As you all know, most of OS files generated by oracle, like traces and logs can be cleared/managed using ADRCI. However, more than once, I saw filesystem get full of Audit Trail files.
In general, I see DBAs and companies implementing shell scripts to house keep those files. Usually some variation of the find with rm I posted some weeks ago. However, we have a very good “official” solition for this, using the DBMS_AUDIT_MGMT.
Basically we can create Scheduler Jobs in our databases to keep track on this. The advantages are seveal. The job clear in both nodes, this keep all Oracle information correctly updated, you may receive OEM notification for failure if monitoring jobs, etc.
You can see more detaiils here in MOS Note 731908.1 New Feature DBMS_AUDIT_MGMT to Manage and Purge Audit Information.
How I did?
1. Initial Cleanup to clear files older than a week.
2. Set last archive to a week ago.
3. Created Purge Job, purging older than a week
