I am not familiar with Data Guard and I am trying to patch a database. It appears that Data Guard may be partially configured. According to sources it would have been done through Grid Control. Archivelog is not running, Fast Start is set to maximum performance and failover is set to disabled. When I log into dgmgrl and issue any commands I get ORA-16525 error code. When I check the switchover_status it returns sessions active value. I have searched for documentation on Data Guard and have not found the right info that can help me figure out the current configuration. If it is a partial configuration I need to know what is missing and how to complete it.
