Unified audit and two policies with the same audit option
I am setting up unified audit on a 12c database and have seen that two policies are per default enabled in Oracle, ORA_SECURECONFIG and ORA_LOGON.
Then there is a created policy but not enabled, ORA_CIS_RECOMMENDATIONS. This policy if enabled would mean that there will be two policies auditing the same Audit Options and that does not make any sense in my world.
It doesn't seem to cause any problems except that only one policy will log the audited action and you can't trace it back to both policies. Not a problem for me but I can think of cases where it would be.
