Solution for Oracle Error ORA-16194

ORA-16194: Modifying DB_UNIQUE_NAME requires SID='*' qualifier

What triggered the Error:

The setting for the DB_UNIQUE_NAME parameter must be exactly the same on all RAC instances so the SID='*' qualifier is required.

What should we do to fix it:

Re-enter the command using the SID='*' qualifier.
