Truncate Takes A Long Time -- Waits on RO enqueue [metalink ID 286363.1]
1. For 10g slow truncate issues, switch off the new feature and revert to 9i functionality model:
ALTER SYSTEM SET "_db_fast_obj_truncate"=FALSE SCOPE=BOTH;
or change the initora/pfile as appropriate.
2. If the performance is to be improved in 9i, try improving the throughput of DBWR.
Setting db_writer_processes can help.
