Applies to:Oracle Server - Enterprise Edition - Version: 10.1.0.2 to 10.2.0.4 - Release: 10.1 to 10.2
Information in this document applies to any platform.
The schema in question is the core schema in a PEOPLESOFT database and it contains about 38000 tables and an even larger number of constraints.
The source of the performance problem is the statement:
SELECT NVL(MAX(CO.SCN), 0) FROM
ALL_CAPTURE_PREPARED_TABLES CO WHERE CO.TABLE_OWNER = :B2 AND CO.TABLE_NAME = :B1
