I have a production environment of Oracle 11g R2 patchset 4 primary database configured with 2 standby machines.
- Primary database unique_name is DBIDI
- 1st standby database unique_name is DBIFI
- 2nd standby database unique_name is DBIGI.
These unique_names are configured in parameter
This parameter is configured through Enterprise Manager with My USER with dba grant. Last night we bounced the primary database. After bounce back, the parameter log_archive_config is changed and DBIGI is removed from this parameter:
Can any one tell what is the reason for this?
