Basis of Presentation and Recent Accounting Pronouncements [Abstract]
BASIS OF PRESENTATION AND RECENT ACCOUNTING PRONOUNCEMENTS	1.    BASIS OF PRESENTATION AND RECENT ACCOUNTING PRONOUNCEMENTS
	Basis of Presentation
	We have prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, we believe that the disclosures herein are adequate to ensure the information presented is not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2014.
	We believe that all necessary adjustments, which consisted only of normal recurring items, have been included in the accompanying financial statements to present fairly the results of the interim periods. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for our fiscal year ending May 31, 2015.
	We adopted Accounting Standards Update No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as Going Concern, during the three months ended November 30, 2014, which had no impact on our reported financial position or results of operations and cash flows. There have been no other significant changes in our reported financial position or results of operations and cash flows as a result of our adoption of other new accounting pronouncements or changes to our significant accounting policies that were disclosed in our Annual Report on Form 10-K for the fiscal year ended May 31, 2014.
	Certain prior year balances have been reclassified to conform to the current year’s presentation. Such reclassifications did not affect our consolidated total revenues, consolidated operating income or consolidated net income.
	Acquisition Related and Other Expenses
	Acquisition related and other expenses consist of personnel related costs for transitional and certain other employees, stock-based compensation expenses, integration related professional services, certain business combination adjustments including adjustments after the measurement period has ended and certain other operating items, net. Stock-based compensation included in acquisition related and other expenses resulted from unvested options and restricted stock-based awards assumed from acquisitions whereby vesting was accelerated upon termination of the employees pursuant to the original terms of those options and restricted stock-based awards.

	Non-Operating Income, net
	Non-operating income, net consists primarily of interest income, net foreign currency exchange gains (losses), the noncontrolling interests in the net profits of our majority-owned subsidiaries (primarily Oracle Financial Services Software Limited and Oracle Japan) and net other income (losses), including net realized gains and losses related to all of our investments and net unrealized gains and losses related to the small portion of our investment portfolio that we classify as trading.

	Sales of Financing Receivables
	We offer certain of our customers the option to acquire our software products, hardware systems products and services offerings through separate long-term payment contracts. We generally sell these contracts that we have financed for our customers on a non-recourse basis to financial institutions within 90 days of the contracts’ dates of execution. We record the transfers of amounts due from customers to financial institutions as sales of financing receivables because we are considered to have surrendered control of these financing receivables. Financing receivables sold to financial institutions were $197 million and $921 million for the three and six months ended November 30, 2014, respectively, and $216 million and $1.0 billion for the three and six months ended November 30, 2013, respectively.
	Recent Accounting Pronouncements
	Share-Based Payments with Performance Targets: In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12). ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification (ASC) 718, Compensation—Stock Compensation (ASC 718), as it relates to such awards. ASU 2014-12 is effective for us in our first quarter of fiscal 2017 with early adoption permitted using either of two methods: (i) prospective to all awards granted or modified after the effective date; or (ii) retrospective to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter, with the cumulative effect of applying ASU 2014-12 as an adjustment to the opening retained earnings balance as of the beginning of the earliest annual period presented in the financial statements. While we are currently evaluating the impact of our pending adoption on ASU 2014-12 on our consolidated financial statements, we do not expect the adoption will have a material impact on our consolidated financial statements.
	Revenue Recognition: In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for us in our first quarter of fiscal 2018 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.
	Reporting Discontinued Operations: In April 2014, the FASB issued Accounting Standards Update No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (ASU 2014-08), to change the criteria for determining which disposals can be presented as discontinued operations and to enhance the related disclosure requirements. ASU 2014-08 is effective for us on a prospective basis in our first quarter of fiscal 2016 with early adoption permitted for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued. While we are currently evaluating the impact of our pending adoption of ASU 2014-08 on our consolidated financial statements, we do not expect the adoption will have a material impact on our consolidated financial statements.

Acquisitions [Abstract]
ACQUISITIONS	2. ACQUISITIONS
	Acquisition of MICROS Systems, Inc.
	On June 22, 2014, we entered into an Agreement and Plan of Merger (Merger Agreement) with MICROS Systems, Inc. (MICROS), a provider of integrated software, hardware and services solutions to the hospitality and retail industries. On July 3, 2014, pursuant to the Merger Agreement, we commenced a tender offer to purchase all of the issued and outstanding shares of common stock of MICROS at a purchase price of $68.00 per share, net to the holder in cash, without interest thereon, based upon the terms and subject to the conditions set forth in the Merger Agreement. Between September 3, 2014 and September 8, 2014, pursuant to the terms of the tender offer, we accepted and paid for the substantial majority of outstanding shares of MICROS common stock. On September 8, 2014, we effectuated the merger of MICROS with and into a wholly-owned subsidiary of Oracle pursuant to the terms of the Merger Agreement and applicable Maryland law and MICROS became an indirect, wholly-owned subsidiary of Oracle. Pursuant to the merger, shares of MICROS common stock that remained outstanding and were not acquired by us were converted into, and cancelled in exchange for, the right to receive $68.00 per share in cash. The unvested equity awards to acquire MICROS common stock that were outstanding immediately prior to the conclusion of the merger were converted into equity awards denominated in shares of Oracle common stock based on formulas contained in the Merger Agreement. We acquired MICROS to, among other things, expand our software and cloud, hardware and related services offerings for hotels, food and beverage industries, facilities, and retailers. We have included the financial results of MICROS in our consolidated financial statements from the date of acquisition.
	Pursuant to our business combinations accounting policy, we estimated the preliminary fair values of net tangible and intangible assets acquired and the excess of the consideration transferred over the aggregate of such fair values was recorded as goodwill. The preliminary fair values of net tangible assets and intangible assets acquired were based upon preliminary valuations and our estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). The primary areas that remain preliminary relate to the fair values of intangible assets acquired, certain tangible assets and liabilities acquired, certain legal matters, income and non-income based taxes and residual goodwill. We expect to continue to obtain information to assist us in determining the fair values of the net assets acquired during the measurement period. The following table summarizes the estimated preliminary fair values of net assets acquired from MICROS:
	(in millions)
	Cash and cash equivalents	$	675
	Trade receivables, net		191
	Inventories		37
	Goodwill		3,304
	Intangible assets		1,966
	Other assets		160
	Accounts payable and other liabilities		-340
	Deferred tax liabilities, net		-620
	Deferred revenues		-126
	Total	$	5,247
	We do not expect the goodwill recognized as a part of the MICROS acquisition to be deductible for income tax purposes.
	Other Fiscal 2015 Acquisitions
	During the first half of fiscal 2015, we acquired certain other companies primarily to expand our products and services offerings. These acquisitions were not significant individually or in the aggregate.
	Fiscal 2014 Acquisitions
	Acquisition of Responsys, Inc.
	On February 6, 2014, we completed our acquisition of Responsys, Inc. (Responsys), a provider of enterprise-scale cloud-based business-to-consumer marketing software. We have included the financial results of Responsys in our consolidated financial statements from the date of acquisition. The total preliminary purchase price for Responsys was approximately $1.6 billion, which consisted of approximately $1.4 billion in cash and $147 million for the fair value of stock options and restricted stock-based awards assumed. We have preliminarily recorded $39 million of net tangible liabilities, related primarily to deferred tax liabilities, $580 million of identifiable intangible assets, and $14 million of in-process research and development, based on their estimated fair values, and $1.0 billion of residual goodwill.
	Other Fiscal 2014 Acquisitions
	During fiscal 2014, we acquired certain other companies and purchased certain technology and development assets primarily to expand our products and services offerings. These acquisitions were not individually significant. We have included the financial results of these companies in our consolidated financial statements from their respective acquisition dates and the results from each of these companies were not individually material to our consolidated financial statements. In the aggregate, the total purchase price for these acquisitions was approximately $2.3 billion, which consisted primarily of cash consideration, and we recorded $238 million of net tangible liabilities, related primarily to deferred tax liabilities, $1.1 billion of identifiable intangible assets, and $99 million of in-process research and development, based on their estimated fair values, and $1.3 billion of residual goodwill.
	The initial purchase price calculation and related accounting for certain of our fiscal 2014 acquisitions is preliminary. The preliminary fair value estimates for the assets acquired and liabilities assumed for certain of our acquisitions completed during fiscal 2014 were based upon preliminary calculations and valuations and our estimates and assumptions for certain of these acquisitions are subject to change as we obtain additional information for our estimates during the respective measurement periods (up to one year from the respective acquisition dates). The primary areas of those preliminary estimates that are not yet finalized relate to certain tangible assets and liabilities acquired, identifiable intangible assets, certain legal matters and income and non-income based taxes.
	Unaudited Pro Forma Financial Information
	The unaudited pro forma financial information in the table below summarizes the combined results of operations for Oracle, MICROS, Responsys, and certain other companies that we acquired since the beginning of fiscal 2014 (which were considered relevant for the purposes of unaudited pro forma financial information disclosure) as though the companies were combined as of the beginning of fiscal 2014. The pro forma financial information for all periods presented also included the business combination accounting effects resulting from these acquisitions, including our amortization charges from acquired intangible assets (certain of which are preliminary), stock-based compensation charges for unvested stock options and restricted stock-based awards assumed, if any, and the related tax effects as though the aforementioned companies were combined as of the beginning of fiscal 2014. The pro forma financial information as presented below is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisitions had taken place at the beginning of fiscal 2014.
	The unaudited pro forma financial information for the three and six months ended November 30, 2014 combined the historical results of Oracle for the three and six months ended November 30, 2014, the historical results of MICROS for the three and six months ended June 30, 2014 (adjusted due to differences in reporting periods and considering the date we acquired MICROS), the historical results of certain other companies that we acquired since the beginning of fiscal 2015 based upon their respective previous reporting periods and the dates these companies were acquired by us, and the effects of the pro forma adjustments listed above.
	The unaudited pro forma financial information for the three and six months ended November 30, 2013 combined the historical results of Oracle for the three and six months ended November 30, 2013, the historical results of MICROS for the three and six months ended December 31, 2013 (due to differences in reporting periods), the historical results of Responsys for the three and six months ended September 30, 2013 (due to differences in reporting periods), the historical results of certain other companies that we acquired since the beginning of fiscal 2014 based upon their respective previous reporting periods and the dates these companies were acquired by us, and the effects of the pro forma adjustments listed above.

FAIR VALUE MEASUREMENTS	6 Months Ended

Fair Value Measurements [Abstract]
FAIR VALUE MEASUREMENTS	3. FAIR VALUE MEASUREMENTS
	We perform fair value measurements in accordance with ASC 820, Fair Value Measurement. ASC 820 defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at their fair values, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the assets or liabilities, such as inherent risk, transfer restrictions and risk of nonperformance.
	ASC 820 establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset’s or a liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. ASC 820 establishes three levels of inputs that may be used to measure fair value:
	·	Level 1: quoted prices in active markets for identical assets or liabilities;
	·	Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or
	·	Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair values of the assets or liabilities.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Our assets and liabilities measured at fair value on a recurring basis, excluding accrued interest components, consisted of the following (Level 1 and 2 inputs are defined above):
			30-Nov-14						31-May-14

As of November 30, 2014 and May 31, 2014, approximately 42% and 45%, respectively, of our marketable securities investments mature within one year and 58% and 55%, respectively, mature within one to four years. Our valuation techniques used to measure the fair values of our marketable securities that were classified as Level 1 in the table above were derived from quoted market prices and active markets for these instruments exist. Our valuation techniques used to measure the fair values of Level 2 instruments listed in the table above, the counterparties to which have high credit ratings, were derived from the following: non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques, with all significant inputs derived from or corroborated by observable market data including LIBOR-based yield curves, among others.
	Based on the trading prices of our $32.5 billion and $24.2 billion of borrowings, which consisted of senior notes that were outstanding as of November 30, 2014 and May 31, 2014, respectively, the estimated fair values of our borrowings using Level 2 inputs at November 30, 2014 and May 31, 2014 were $34.8 billion and $26.4 billion, respectively.

	Senior Notes
	In July 2014, we issued $10.0 billion of senior notes comprised of $1.0 billion of floating rate notes due July 2017 (2017 Notes), $750 million of floating rate notes due October 2019 (2019 Floating Rate Notes), $2.0 billion of 2.25% notes due October 2019 (2019 Notes), $1.5 billion of 2.80% notes due July 2021 (2021 Notes), $2.0 billion of 3.40% notes due July 2024 (2024 Notes), $1.75 billion of 4.30% notes due July 2034 (2034 Notes) and $1.0 billion of 4.50% notes due July 2044 (2044 Notes and, together with the 2017 Notes, 2019 Floating Rate Notes, 2019 Notes, 2021 Notes, 2024 Notes and 2034 Notes, the Senior Notes). The floating rate notes bear interest at a floating rate equal to three-month LIBOR plus 0.20% for the 2017 Notes and 0.51% for the 2019 Floating Rate Notes (0.43% and 0.74% as of November 30, 2014, respectively) with interest payable quarterly. We issued the Senior Notes for general corporate purposes, which may include stock repurchases, payment of cash dividends on our common stock, our acquisition of MICROS and future acquisitions, and repayment of indebtedness.
	The effective interest yields of the 2019 Notes, 2021 Notes, 2024 Notes, 2034 Notes and 2044 Notes (collectively, the Fixed Rate Senior Notes) at November 30, 2014 were 2.27%, 2.82%, 3.43%, 4.30% and 4.50%, respectively, and interest is payable semi-annually. In July 2014, we entered into certain interest rate swap agreements that have the economic effect of modifying the fixed interest obligations associated with the 2019 Notes and 2021 Notes so that the interest payable on these notes effectively became variable based on LIBOR (0.72% and 0.87%, respectively, at November 30, 2014; see Note 9 for additional information). We may redeem some or all of the Fixed Rate Senior Notes of each series prior to their maturity, subject to certain restrictions, and the payment of an applicable make-whole premium in certain instances. The 2017 Notes and 2019 Floating Rate Notes may not be redeemed prior to their maturity.
	The Senior Notes rank pari passu with any other notes we may issue in the future pursuant to our commercial paper program and all existing and future unsecured senior indebtedness of Oracle Corporation (see Note 8 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2014 for further information on our commercial paper program and other borrowings). All existing and future liabilities of the subsidiaries of Oracle Corporation are or will be effectively senior to the Senior Notes and any future issuances of commercial paper notes. We were in compliance with all debt-related covenants at November 30, 2014.
	In July 2014, our 3.75% senior notes due July 2014 (2014 Notes) for $1.5 billion matured and were repaid, and we settled the fixed to variable interest rate swap agreements associated with such fixed rate senior notes.
	There have been no other significant changes in our notes payable or other borrowing arrangements that were disclosed in our Annual Report on Form 10-K for the fiscal year ended May 31, 2014.

	Fiscal 2015 Oracle Restructuring Plan
	During the second quarter of fiscal 2015, our management approved, committed to and initiated plans to restructure and further improve efficiencies in our operations due to our acquisition of MICROS and certain other operational activities (2015 Restructuring Plan). The total estimated restructuring costs associated with the 2015 Restructuring Plan are up to $626 million and will be recorded to the restructuring expense line item within our consolidated statements of operations as they are incurred. We recorded $13 million of restructuring expenses in connection with the 2015 Restructuring Plan in the first half of fiscal 2015 and we expect to incur the majority of the estimated remaining $613 million through the end of fiscal 2016. Any changes to the estimates of executing the 2015 Restructuring Plan will be reflected in our future results of operations.
	Fiscal 2013 Oracle Restructuring Plan
	During the first quarter of fiscal 2013, our management approved, committed to and initiated plans to restructure and further improve efficiencies in our operations (2013 Restructuring Plan). Restructuring costs associated with the 2013 Restructuring Plan were recorded to the restructuring expense line item within our consolidated statements of operations as they were incurred. We recorded $120 million of restructuring expenses in connection with the 2013 Restructuring Plan in the first half of fiscal 2015. Actions pursuant to the 2013 Restructuring Plan were substantially complete as of November 30, 2014, a portion of which remained outstanding for cash settlement.

	Total deferred revenues	$	7,224	$	7,673
	Deferred software license updates and product support revenues and deferred hardware systems support revenues represent customer payments made in advance for support contracts that are typically billed on a per annum basis in advance with corresponding revenues being recognized ratably over the support periods. Deferred services revenues include prepayments for our services business and revenues for these services are generally recognized as the services are performed. Deferred cloud software-as-a-service (SaaS), platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) revenues generally result from our cloud-based offerings that are typically billed in advance and recognized over the corresponding contractual term. Deferred new software licenses revenues typically result from undelivered products or specified enhancements, customer specific acceptance provisions, customer payments made in advance for time-based license arrangements and software license transactions that cannot be separated from undelivered consulting or other services.
	In connection with our acquisitions, we have estimated the fair values of the cloud SaaS and PaaS, software license updates and product support, and hardware systems support obligations, among others, assumed from our acquired companies. We generally have estimated the fair values of these obligations assumed using a cost build-up approach. The cost build-up approach determines fair value by estimating the costs related to fulfilling the obligations plus a normal profit margin. The sum of the costs and operating profit approximates, in theory, the amount that we would be required to pay a third party to assume these acquired obligations. These aforementioned fair value adjustments recorded for obligations assumed from our acquisitions reduced the cloud SaaS and PaaS, software license updates and product support and hardware systems support deferred revenues balances that we recorded as liabilities from these acquisitions and also reduced the resulting revenues that we recognized or will recognize over the terms of the acquired obligations during the post-combination periods.

Derivative Financial Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	9. DERIVATIVE FINANCIAL INSTRUMENTS
	Fair Value Hedges—Interest Rate Swap Agreements
	In July 2014, we entered into certain interest rate swap agreements that have the economic effect of modifying the fixed interest obligations associated with our 2019 Notes and 2021 Notes so that the interest payable on these senior notes effectively became variable based on LIBOR. In July 2013, we entered into certain interest rate swap agreements that have the economic effect of modifying the fixed interest obligations associated with our $1.5 billion of 2.375% senior notes due January 2019 (January 2019 Notes) so that the interest payable on these senior notes effectively became variable based on LIBOR. The critical terms of the interest rate swap agreements and the 2019 Notes, 2021 Notes and the January 2019 Notes that the interest rate swap agreements pertain to match, including the notional amounts and maturity dates.
	We have designated the aforementioned interest rate swap agreements as qualifying hedging instruments and are accounting for them as fair value hedges pursuant to ASC 815, Derivatives and Hedging (ASC 815). These transactions are characterized as fair value hedges for financial accounting purposes because they protect us against changes in the fair values of certain of our fixed rate borrowings due to benchmark interest rate movements. The changes in fair values of these interest rate swap agreements are recognized as interest expense in our consolidated statements of operations with the corresponding amounts included in other assets or other non-current liabilities in our consolidated balance sheets. The amount of net gain (loss) attributable to the risk being hedged is recognized as interest expense in our consolidated statements of operations with the corresponding amount included in notes payable and other non-current borrowings. The periodic interest settlements for the interest rate swap agreements for the 2019 Notes, 2021 Notes and the January 2019 Notes are recorded as interest expense and are included as a part of cash flows from operating activities.
	In July 2014, we settled the fixed to variable interest rate swap agreements associated with the 2014 Notes. We do not use any interest rate swap agreements for trading purposes.
	Cash Flow Hedges—Cross Currency Swap Agreements
	In connection with the issuance of our €1.25 billion of 2.25% senior notes due January 2021 (January 2021 Notes), we entered into certain cross-currency swap agreements to manage the related foreign currency exchange risk by effectively converting the fixed-rate, Euro denominated January 2021 Notes, including the annual interest payments and the payment of principal at maturity, to fixed-rate, U.S. Dollar denominated debt. The economic effect of the swap agreements was to eliminate the uncertainty of the cash flows in U.S. Dollars associated with the January 2021 Notes by fixing the principal amount of the January 2021 Notes at $1.6 billion with a fixed annual interest rate of 3.53%. We have designated these cross-currency swap agreements as qualifying hedging instruments and are accounting for these as cash flow hedges pursuant to ASC 815. The critical terms of the cross-currency swap agreements correspond to the January 2021 Notes, including the annual interest payments being hedged, and the cross-currency swap agreements mature at the same time as the January 2021 Notes.
	We used the hypothetical derivative method to measure the effectiveness of our cross-currency swap agreements. The fair values of these cross-currency swap agreements are recognized as other assets or other non-current liabilities in our consolidated balance sheets. The effective portions of the changes in fair values of these cross-currency swap agreements are reported in accumulated other comprehensive loss in our consolidated balance sheets and an amount is reclassified out of accumulated other comprehensive loss into non-operating income, net in the same period that the carrying value of the Euro denominated January 2021 Notes is remeasured and the interest expense is recognized. The ineffective portion of the unrealized gains and losses on these cross-currency swaps, if any, is recorded immediately to non-operating income, net. We evaluate the effectiveness of our cross-currency swap agreements on a quarterly basis. We did not record any ineffectiveness for the six months ended November 30, 2014. The cash flows related to the cross-currency swap agreements that pertain to the periodic interest settlements are classified as operating activities and the cash flows that pertain to the principal balance are classified as financing activities.
	We do not use any cross-currency swap agreements for trading purposes.
	Net Investment Hedge—Foreign Currency Borrowings
	In July 2013, we designated our €750 million of 3.125% senior notes due July 2025 (2025 Notes) as a net investment hedge of our investments in certain of our international subsidiaries that use the Euro as their functional currency in order to reduce the volatility in stockholders’ equity caused by the changes in foreign currency exchange rates of the Euro with respect to the U.S. Dollar.
	We used the spot method to measure the effectiveness of our net investment hedge. Under this method, for each reporting period, the change in the carrying value of the Euro denominated 2025 Notes due to remeasurement of the effective portion is reported in accumulated other comprehensive loss on our consolidated balance sheet and the remaining change in the carrying value of the ineffective portion, if any, is recognized in non-operating income, net in our consolidated statements of operations. We evaluate the effectiveness of our net investment hedge at the beginning of every quarter. We did not record any ineffectiveness for the six months ended November 30, 2014.
	Foreign Currency Forward Contracts Not Designated as Hedges
	We transact business in various foreign currencies and have established a program that primarily utilizes foreign currency forward contracts to offset the risks associated with the effects of certain foreign currency exposures. We neither use these foreign currency forward contracts for trading purposes nor do we designate these forward contracts as hedging instruments pursuant to ASC 815 (refer to Note 11 of Notes to Consolidated Financial Statements as included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2014 for additional information regarding these contracts). As of November 30, 2014 and May 31, 2014, respectively, the notional amounts of the forward contracts we held to purchase U.S. Dollars in exchange for other major international currencies were $3.0 billion and $3.6 billion, respectively, and the notional amounts of forward contracts we held to sell U.S. Dollars in exchange for other major international currencies were $1.0 billion and $2.0 billion, respectively. The fair values of our outstanding foreign currency forward contracts were nominal at November 30, 2014 and May 31, 2014. Included in our non-operating income, net were $66 million and $35 million of net gains related to these forward contracts for the three and six months ended November 30, 2014, respectively, and $77 million and $9 million of net losses for the three and six months ended November 30, 2013, respectively. The cash flows related to these foreign currency contracts are classified as operating activities.
	The effects of derivative and non-derivative instruments designated as hedges on certain of our consolidated financial statements were as follows as of or for each of the respective periods presented below (amounts presented exclude any income tax effects):

	Stock Repurchases
	Our Board of Directors has approved a program for us to repurchase shares of our common stock. On September 18, 2014, we announced that our Board of Directors approved an expansion of our stock repurchase program by an additional $13.0 billion. Approximately $13.2 billion remained available for stock repurchases as of November 30, 2014, pursuant to our stock repurchase program. We repurchased 101.6 million shares for $4.1 billion during the six months ended November 30, 2014 (including 2.3 million shares for $95 million that were repurchased but not settled) and 176.1 million shares for $5.8 billion during the six months ended November 30, 2013 under the stock repurchase program.
	Our stock repurchase authorization does not have an expiration date and the pace of our repurchase activity will depend on factors such as our working capital needs, our cash requirements for acquisitions and dividend payments, our debt repayment obligations or repurchase of our debt, our stock price, and economic and market conditions. Our stock repurchases may be effected from time to time through open market purchases or pursuant to a Rule 10b5-1 plan. Our stock repurchase program may be accelerated, suspended, delayed or discontinued at any time.
	Dividends on Common Stock
	During the six months ended November 30, 2014, our Board of Directors declared cash dividends of $0.24 per share of our outstanding common stock, which we paid during the same period.
	In December 2014, our Board of Directors declared a quarterly cash dividend of $0.12 per share of our outstanding common stock payable on January 28, 2015 to stockholders of record as of the close of business on January 7, 2015. Future declarations of dividends and the establishment of future record and payment dates are subject to the final determination of our Board of Directors.
	Stock-Based Compensation Expense and Valuations of Stock Awards
	During the first half of fiscal 2015, we issued 35 million stock options and 24 million restricted stock-based awards, which primarily included awards issued as a part of our annual stock-based award process and awards from companies that we have acquired, that were subject to service-based vesting restrictions. Included in the aforementioned restricted stock-based award total were 3 million of performance-based restricted stock units (PSUs) that vest upon the attainment of certain performance metrics and service-based vesting. Based upon actual attainment relative to the “target” performance metric, certain participants have the ability to be issued up to 150% of the target number of PSUs originally granted, or to be issued no PSUs at all. For each share granted as a restricted stock-based award under our 2000 Long-Term Equity Incentive Plan, an equivalent of 2.5 shares is deducted from our pool of available stock awards. Our stock option and restricted stock-based award issuances were partially offset by forfeitures and cancellations of 12 million shares during the first half of fiscal 2015.
	We estimated the fair values of our stock options using the Black-Scholes-Merton option-pricing model, which was developed for use in estimating the fair values of stock options. Option valuation models, including the Black-Scholes-Merton option-pricing model, require the input of assumptions, including stock price volatility. Changes in the input assumptions can materially affect the fair value estimates and ultimately how much we recognize as stock-based compensation expense. We recognize stock-based compensation expense on a straight-line basis over the service period of the stock option, which is generally four years. The fair values of our stock options were estimated at the grant dates or at the acquisition dates for options assumed in a business combination. The weighted average input assumptions used and resulting fair values of our stock options were as follows for the three and six months ended November 30, 2014 and 2013:
		Three Months Ended				Six Months Ended
		November 30,				November 30,
		2014		2013		2014		2013
	Expected life (in years)		4.9		4.7		5.1		5.1
	Risk-free interest rate		1.70%		1.30%		1.70%		1.40%
	Volatility		23%		24%		23%		27%
	Dividend yield		1.20%		1.50%		1.20%		1.60%
	Weighted-average fair value per share	$	10.94	$	6.28	$	8.97	$	6.62
	The expected life input is based on historical exercise patterns and post-vesting termination behavior, the risk-free interest rate input is based on U.S. Treasury instruments, the annualized dividend yield input is based on the per share dividend declared by our Board of Directors and the volatility input is calculated based on the implied volatility of our publicly traded options.
	We estimated the fair values of our restricted-stock based awards that are solely subject to service-based vesting requirements based upon their intrinsic values as of the grant dates. We recognize expense for these service-based awards on a straight-line basis over the service period of these awards, which is generally four years.
	The fair values of our PSUs were also measured at their intrinsic values as of their respective grant dates. The vesting conditions and related terms of our PSUs were communicated to each participating employee as of their respective grant dates and include attainment metrics that are defined, fixed, and based upon consistent U.S. GAAP metrics or internal metrics that are defined, fixed and consistently determined, and that require the employee to render service. Therefore, these awards meet the performance-based award classification criteria as defined within ASC 718. The performance conditions of the PSUs affect the number of PSUs that will ultimately vest and be issued to the grantee based upon a “target” that is subject to certain attainment maximums, with the possibility that none will vest if applicable performance conditions are not met. As the performance conditions to evaluate attainment of each tranche for each participant are independent of the performance conditions for the other tranches, we recognize stock-based compensation expense for our PSUs on a straight-line basis over the service period for each separately vesting tranche, which is generally twelve months.
	Stock-based compensation is included in the following operating expense line items in our condensed consolidated statements of operations:
		Three Months Ended				Six Months Ended

Income Taxes [Abstract]
INCOME TAXES	11.    INCOME TAXES
	The effective tax rate for the periods presented is the result of the mix of income earned in various tax jurisdictions that apply a broad range of income tax rates. Our provision for income taxes differs from the tax computed at the U.S. federal statutory income tax rate due primarily to certain earnings considered as indefinitely reinvested in foreign operations, state taxes, the U.S. research and development tax credit, acquisition related settlements with tax authorities and the U.S. domestic production activity deduction. Our effective tax rate was 23.5% and 21.7% for the three and six months ended November 30, 2014, respectively, and 20.3% and 19.1% for the three and six months ended November 30, 2013, respectively.
	Our net deferred tax assets were $908 million and $1.4 billion as of November 30, 2014 and May 31, 2014, respectively. We believe it is more likely than not that the net deferred tax assets will be realized in the foreseeable future. Realization of our net deferred tax assets is dependent upon our generation of sufficient taxable income in future years in appropriate tax jurisdictions to obtain benefit from the reversal of temporary differences, net operating loss carryforwards and tax credit carryforwards. The amount of net deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income change.
	Domestically, U.S. federal and state taxing authorities are currently examining income tax returns of Oracle and various acquired entities for years through fiscal 2013. Our U.S. federal and, with some exceptions, our state income tax returns have been examined for all years prior to fiscal 2003 and we are no longer subject to audit for those periods.
	Internationally, tax authorities for numerous non-U.S. jurisdictions are also examining returns affecting our unrecognized tax benefits. With some exceptions, we are generally no longer subject to tax examinations in non-U.S. jurisdictions for years prior to fiscal 1997.
	We believe that we have adequately provided for any reasonably foreseeable outcomes related to our tax audits and that any settlement will not have a material adverse effect on our consolidated financial position or results of operations. However, there can be no assurances as to the possible outcomes.

Segment Information [Abstract]
SEGMENT INFORMATION	12.    SEGMENT INFORMATION
	ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision makers are our Chief Executive Officers. We are organized geographically and by line of business. While our Chief Executive Officers evaluate results in a number of different ways, the line of business management structure is the primary basis for which the allocation of resources and financial results are assessed.
	We have three businesses—software and cloud, hardware systems and services—which are further divided into certain operating segments. Our software and cloud business is comprised of three operating segments: (1) new software licenses and cloud software subscriptions, which includes our cloud SaaS and PaaS offerings, (2) cloud infrastructure-as-a-service and (3) software license updates and product support. Our hardware systems business is comprised of two operating segments: (1) hardware systems products and (2) hardware systems support. All other operating segments are combined under our services business.
	The new software licenses and cloud software subscriptions line of business is engaged in the licensing of our database and middleware software, as well as our application software, and providing access to a broad range of our software through Oracle Cloud SaaS and PaaS offerings on a subscription basis via a cloud-based IT environment that we manage, host and support.
	The cloud infrastructure-as-a-service line of business provides deployment and management offerings for our software and hardware and related IT infrastructure including virtual machine instances that are subscription-based and designed for computing and reliable and secure object storage; Oracle Engineered Systems hardware and related support that are deployed in our customers’ data centers for a monthly fee; and comprehensive software and hardware management and maintenance services for customer IT infrastructure for a fee for a stated term that is hosted at our data center facilities, select partner data centers or physically on-premise at customer facilities.
	The software license updates and product support line of business provides customers with rights to software product upgrades and maintenance releases, patches released, internet access to technical content, as well as internet and telephone access to technical support personnel during the support period.
	The hardware systems products line of business consists primarily of servers, storage, networking, point-of-sale hardware, virtualization software, operating systems including the Oracle Solaris Operating System and management software to support diverse IT environments, including cloud computing environments. As a part of this line of business, we offer our Oracle Engineered Systems, including our Oracle Exadata Database Machine, among others.
	Our hardware systems support line of business provides customers with software updates for the software components that are essential to the functionality of our server and storage products, such as Oracle Solaris and certain other software products, and can include product repairs, maintenance services and technical support services.
	Our services business is comprised of the remainder of our operating segments and offers consulting, advanced customer support services and education services. Our consulting line of business primarily provides services to customers in business and IT strategy alignment, enterprise architecture planning and design, initial product implementation and integration and ongoing product enhancements and upgrades. Advanced customer support provides support services, both on-premise and remote, to our customers to enable increased performance and higher availability of their products and services. Education services provide training to customers, partners and employees as a part of our mission of accelerating the adoption and use of our software and hardware products and to create opportunities to grow our product revenues.
	We do not track our assets by operating segments. Consequently, it is not practical to show assets by operating segment.
	The following table presents summary results for each of our three businesses and for the operating segments of our software and cloud and hardware systems businesses:

Earnings Per Share [Abstract]
EARNINGS PER SHARE	13.    EARNINGS PER SHARE
	Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding stock options, restricted stock-based awards and shares issuable under the employee stock purchase plan using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share:

Legal Proceedings [Abstract]
LEGAL PROCEEDINGS	14. LEGAL PROCEEDINGS
	SAP Intellectual Property Litigation
	On March 22, 2007, Oracle Corporation, Oracle USA, Inc. and Oracle International Corporation (collectively, Oracle) filed a complaint in the United States District Court for the Northern District of California against SAP AG, its wholly-owned subsidiary, SAP America, Inc., and its wholly-owned subsidiary, TomorrowNow, Inc., (the SAP Subsidiary, and collectively, the SAP Defendants) alleging that SAP unlawfully accessed Oracle’s Customer Connection support website and improperly took and used Oracle’s intellectual property.
	Trial commenced on November 1, 2010 on the issue of damages, as SAP had stipulated to liability. The jury awarded Oracle $1.3 billion. On September 1, 2011, the court granted the SAP Defendants’ motion for judgment as a matter of law and for a new trial. The court vacated the $1.3 billion award and held that Oracle could either accept a reduced amount or remittitur of $272 million or proceed to a new trial. On February 6, 2012, Oracle rejected the remittitur and requested a new trial.
	On August 2, 2012, Oracle and the SAP Defendants stipulated to a judgment of $306 million against the SAP Defendants, in lieu of having a second jury trial, while preserving both parties’ rights to appeal prior court orders. We recorded a $306 million receivable in our consolidated balance sheet and we recognized a corresponding benefit to our results of operations for the first quarter of fiscal 2013. Previously during trial we received payment of $120 million in attorneys' fees from SAP under a stipulation, and we recorded this payment upon receipt as a benefit to our results of operations during the second quarter of fiscal 2011. On August 3, 2012, the court entered the judgment and vacated the date set for the new trial. Oracle filed a Notice of Appeal on August 31, 2012, and the SAP Defendants filed a notice of appeal on September 14, 2012. The SAP Defendants subsequently dismissed their appeal. The appellate court heard oral argument on May 13, 2014, and on August 29, 2014, issued an order affirming the district court's grant of judgment as a matter of law but vacated the district court's ruling selecting $272 million as the remittitur amount. The appellate court remanded for a new trial, with instructions to condition any new trial on Oracle's rejection of a $356.7 million remittitur. Oracle accepted the remittitur proposed by the appellate court and final judgment was entered on November 14, 2014, in the amount of $356.7 million plus post-judgment interest of approximately $2.5 million. During the second quarter of fiscal 2015, Oracle received the total payment of approximately $359.2 million, of which $306 million was applied against the receivable recorded in the first quarter of fiscal 2013 and the excess of $53 million was recorded as a benefit to our results of operations. On November 25, 2014, the SAP Defendants filed a Satisfaction of Judgment. This action is now concluded.
	Hewlett-Packard Company Litigation
	On June 15, 2011, Hewlett-Packard Company (“HP”) filed a complaint in the California Superior Court, County of Santa Clara against Oracle Corporation alleging numerous causes of action including breach of contract, breach of the covenant of good faith and fair dealing, defamation, intentional interference with prospective economic advantage, and violation of the California Unfair Business Practices Act. The complaint alleged that when Oracle announced on March 22 and 23, 2011 that it would no longer develop future versions of its software to run on HP’s Itanium-based servers, it breached a settlement agreement signed on September 20, 2010 between HP and Mark Hurd (the “Hurd Settlement Agreement”), who was both HP’s former chief executive officer and chairman of HP’s board of directors. HP sought a judicial declaration of the parties’ rights and obligations under the Hurd Settlement Agreement, and other equitable and monetary relief.
	Oracle answered the complaint and filed a cross-complaint, which was amended on December 2, 2011. The amended cross-complaint alleged claims including violation of the Lanham Act. Oracle alleged that HP had secretly agreed to pay Intel to continue to develop and manufacture the Itanium microprocessor, and had misrepresented to customers that the Itanium microprocessor had a long roadmap, among other claims. Oracle sought equitable rescission of the Hurd Settlement Agreement, and other equitable and monetary relief.
	The court bifurcated the trial and tried HP’s causes of action for declaratory relief and promissory estoppel without a jury in June 2012. The court issued a final statement of decision on August 28, 2012, finding that the Hurd Settlement Agreement required Oracle to continue to develop certain of its software products for use on HP’s Itanium-based servers and to port such products at no cost to HP for as long as HP sells those servers. Oracle has announced that it is appealing this decision. The issues of breach, HP’s performance, causation and damages, HP’s tort claims, and Oracle’s cross-claims will all be tried before a jury. As of April 8, 2013, the trial is stayed pending Oracle’s appeal of the court’s denial of its anti-SLAPP motion, which is fully briefed, although oral argument has not yet been scheduled. We cannot currently estimate a reasonably possible range of loss for this action. We believe that we have meritorious defenses against this action, and we will continue to vigorously defend it.
	Other Litigation
	We are party to various other legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business, including proceedings and claims that relate to acquisitions we have completed or to companies we have acquired or are attempting to acquire. While the outcome of these matters cannot be predicted with certainty, we do not believe that the outcome of any of these matters, individually or in the aggregate, will result in losses that are materially in excess of amounts already recognized, if any.

ACCOUNTING POLICIES (Policy)	6 Months Ended

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	Share-Based Payments with Performance Targets: In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12). ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification (ASC) 718, Compensation—Stock Compensation (ASC 718), as it relates to such awards. ASU 2014-12 is effective for us in our first quarter of fiscal 2017 with early adoption permitted using either of two methods: (i) prospective to all awards granted or modified after the effective date; or (ii) retrospective to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter, with the cumulative effect of applying ASU 2014-12 as an adjustment to the opening retained earnings balance as of the beginning of the earliest annual period presented in the financial statements. While we are currently evaluating the impact of our pending adoption on ASU 2014-12 on our consolidated financial statements, we do not expect the adoption will have a material impact on our consolidated financial statements.
	Revenue Recognition: In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 is effective for us in our first quarter of fiscal 2018 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.
	Reporting Discontinued Operations: In April 2014, the FASB issued Accounting Standards Update No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (ASU 2014-08), to change the criteria for determining which disposals can be presented as discontinued operations and to enhance the related disclosure requirements. ASU 2014-08 is effective for us on a prospective basis in our first quarter of fiscal 2016 with early adoption permitted for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued. While we are currently evaluating the impact of our pending adoption of ASU 2014-08 on our consolidated financial statements, we do not expect the adoption will have a material impact on our consolidated financial statements.

Software license updates and product support revenues for management reporting included revenues related to software support contracts that would have otherwise been recorded by the acquired businesses as independent entities but were not recognized in the accompanying condensed consolidated statements of operations in the amounts of $5 million and $1 million for the three months ended November 30, 2014 and 2013, respectively, and $6 million and $1 million for the six months ended November 30, 2014 and 2013, respectively. In addition, we did not recognize hardware systems support revenues related to hardware systems support contracts that would have otherwise been recorded by the acquired businesses as independent entities in the amounts of $2 million and $4 million for the three months ended November 30, 2014 and 2013, respectively, and $2 million and $10 million for the six months ended November 30, 2014 and 2013, respectively. See Note 8 for an explanation of these adjustments and the table below for a reconciliation of our total operating segment revenues to our total revenues. Our new software license and services revenues for management reporting also differ from amounts reported per our consolidated statements of operations for the periods presented due to certain insignificant reclassifications between these lines for management reporting purposes.

Additionally, the margins do not reflect amortization of intangible assets, acquisition related and other expenses, restructuring expenses, stock-based compensation, interest expense or certain other income (expense), net.

[1]	New software licenses and cloud software subscriptions revenues, software license updates and product support revenues and hardware systems support revenues for management reporting included revenues that would have otherwise been recorded by our acquired businesses as independent entities but were not recognized in the accompanying condensed consolidated statements of operations for the periods presented due to business combination accounting requirements. Refer to footnote (1) of our business and operating segments summary results table above in this Note 12 for additional information.

Software license updates and product support revenues for management reporting included revenues related to software support contracts that would have otherwise been recorded by the acquired businesses as independent entities but were not recognized in the accompanying condensed consolidated statements of operations in the amounts of $5 million and $1 million for the three months ended November 30, 2014 and 2013, respectively, and $6 million and $1 million for the six months ended November 30, 2014 and 2013, respectively. In addition, we did not recognize hardware systems support revenues related to hardware systems support contracts that would have otherwise been recorded by the acquired businesses as independent entities in the amounts of $2 million and $4 million for the three months ended November 30, 2014 and 2013, respectively, and $2 million and $10 million for the six months ended November 30, 2014 and 2013, respectively. See Note 8 for an explanation of these adjustments and the table below for a reconciliation of our total operating segment revenues to our total revenues. Our new software license and services revenues for management reporting also differ from amounts reported per our consolidated statements of operations for the periods presented due to certain insignificant reclassifications between these lines for management reporting purposes.
