Thanks for your reply Osama, but its not even there.
I want to put AUDIT/LOG on skipping and unskipping of tables performed by the DBA.
Given that your Database is 10g, the auditing options were extended to included DML from only SELECT in 9i, but not audit on procedures. You could double check the Fine Grained Auditing options in 10g, but I don't think this extends to DBMS_ packages.
I would consider writing a trigger or a small job that monitors the DBA_LOGSTDBY_SKIP view for additional entries. This is the only workaround that I can suggest that might fit your needs.
