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.
A switchover was performed between a physical standby and a primary databases.
Initially both primary and standby databases had the parameter audit_trail set 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.
