Failover:

Prerequisites:

  • Standby database must be in MOUNT state.

Usage:

CMD> ubguard.sh failover to <ubguard_database_alias> [-f]

Default Failover:

It is a failover without "-f" option. It applies archivelogs to standby database, activates standby database as primary database. It causes less data loss, but longer failover time.

The alternative manual method by RMAN on standby:

CMD> ubguard.sh stop guard -d <ubguard_database_alias>
CMD> SET ORACLE_SID=<SID>
CMD> rman target /
RMAN> RECOVER DATABASE;
RMAN> SQL 'ALTER DATABASE ACTIVATE STANDBY DATABASE';
RMAN> ALTER DATABASE OPEN;
RMAN> EXIT;

If the manual method is used, ubGuard setup must be run again to update ubGuard's catalog.

Forced Failover:

It is a failover with "-f" option. It doesn't apply archivelogs to standby database. It activates standby database as primary database. It causes more data loss, but less failover time.

The alternative manual method by RMAN on standby:

CMD> ubguard.sh stop guard -d <ubguard_database_alias>
CMD> SET ORACLE_SID=<SID>
CMD> rman target /
RMAN> SQL 'ALTER DATABASE ACTIVATE STANDBY DATABASE';
RMAN> ALTER DATABASE OPEN;
RMAN> EXIT;

If the manual method is used, ubGuard setup must be run again to update ubGuard's catalog.

Switchover:

Prerequisites:

  • Primary database must be in MOUNT or OPEN state.
  • Standby database must be in MOUNT state.

Usage:

CMD> ubguard.sh switchover to <ubguard_database_alias>
