Symptoms

After a Data Guard switchover of a physical standby database, the initialization parameter AUDIT_TRAIL is not converted to DB in the new primary database.

Changes

A switchover was performed between a physical standby and a primary databases.

Initialy both primary and standby databases had the parameter audit_trailset to DB.

The ADG (Active Data Guard) was set up in standby database which set the audit_trail to OS in that standby, as expected.

After a switchover the primary became a standby and the standby became a primary. The parameter audit_trail had a value of OS in both databases.

Instead of retaining the value DB in the primary instance, it was changed by the Data Guard to audit_trail = OS.
