1. Log in to SQL*Plus as user SYS with the SYSDBA administrative privilege.
2. Find out if your database has been migrated to use unified auditing. (if not, complete the remaining steps)
3. Stop the database
4. Stop the listener. (Stopping the listener is not necessary for Oracle RAC and Grid Infrastructure listeners.)
5. Go to the $ORACLE_HOME/rdbms/lib directory
6. Enable the unified auditing executable (make -f ins_rdbms.mk uniaud_on ioracle ORACLE_HOME=$ORACLE_HOME)
7. Restart the listener
8. Restart the database
