Oracle: error messages for read only database

The old Oracle database (8i) was switched to the read-only mode. The following messages are shown now in alert.log:
***Warning – Executing transaction without active Undo Tablespace

It’s possible, that the error is caused by Oracle bug 3270493 (EXCESSIVE QMNX TRACE FILES WHEN PLACING STANDBY IN READ ONLY MODE). Workaround is to set aq_tm_processes parameter to 0:


ALTER SYSTEM SET aq_tm_processes=0;
