How to set AUDIT_TRAIL=DB in a snapshot standby database?
I converted a physical standby database (12.2.0.1) to a SNAPSHOT STANDBY with an spfile containing AUDIT_TRAIL=DB.
According to the alertlog the AUDIT_TRAIL is reset to OS when this database is opened : "AUDIT_TRAIL initialization parameter is changed to OS, as DB is NOT compatible for database opened with read-only access"
Since a SNAPSHOT STANDBY database is opened READ-WRITE, we want auditing on it in the database (SYS.AUD$). Is there a workaround to bypass this reset of AUDIT_TRAIL?
Thanks,
Koen
