   --------------

1. I have reviewed this report on Form N-CSR of Oppenheimer Senior Floating Rate
Fund;

2. Based on my knowledge, this report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements

information included in this report, fairly present in all material respects the

flows (if the financial statements are required to include a statement of cash

4. The registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Rule 30a-2(c) under the Investment Company Act of 1940) for the registrant and
have:

a) designed such disclosure controls and procedures, or caused such disclosure
controls and procedures to be designed under our supervision, to ensure that
material information relating to the registrant, including its consolidated
subsidiaries, is made known to us by others within those entities, particularly
during the period in which this report is being prepared;

b) evaluated the effectiveness of the registrant's disclosure controls and
procedures and presented in this report our conclusions about the effectiveness
of the disclosure controls and procedures, as of a date within 90 days prior to
the filing date of this report based on such evaluation; and

c) disclosed in this report any change in the registrant's internal control over
financial reporting that occurred during the registrant's most last fiscal
half-year that has materially affected, or is reasonably likely to materially
affect, the registrant's internal control over financial reporting.

5. The registrant's other certifying officers and I have disclosed to the
registrant's auditors and the audit committee of the registrant's board of
trustees (or persons performing the equivalent functions):

a) all significant deficiencies and material weaknesses in the design or
operation of internal controls which are reasonably likely to adversely affect
the registrant's ability to record, process, summarize, and report financial
information; and

b) any fraud, whether or not material, that involves management or other
employees who have a significant role in the registrant's internal control over
financial reporting.
