ORA-15591: encountered corrupt workload capture files

文档解释

ORA-15591: encountered corrupt workload capture files

Cause: The captured workload contained one or more corrupt recording files.

Action: For a list of the incomplete files, check the alert log for lines containing DBMS_WORKLOAD_REPLAY.PROCESS_CAPTURE after capture processing. The corrupt files will be replayed up to the point of the corruption. Alternatively, it is possible to remove the corrupt files and run DBMS_WORKLOAD_REPLAY.PROCESS_CAPTURE again. In this case, no workload from the corrupt files will be replayed.
