CHANGES

Executed
SQL> grant sysdba to xxxx;
on the Primary Database

CAUSE

Bug 3013741: ORA-1031: INSUFFICIENT PRIVILEGES ERROR ON LOGICAL DB IN DATA GUARD MANAGER

A Background Process, e.g., a Logcial Apply Slave, never runs with SYSDBA Privileges. This would be needed to perform the grant of the SYSDBA privileges.


.

SOLUTION

At standby side, grant sysdba to xxxx manually
SQL> alter session disable guard;
SQL> grant sysdba to xxxx;
SQL> alter session enable guard;

2. Skip the Transaction of the grant using DBMS_LOGSTDBY.SKIP_TRANSACTION

2.1 Check xid with the grant.
