When disaster strikes and the primary database is no longer available the standby database must be activated to become the new primary database to continue operation.
To activate and open the standby database for continued operation in the event of a disaster the following procedure must be used: |

1. Manually run Dbvisit Standby to ensure all log files have been applied.

The new production database is now operational and users can connect to continue operation. Once the old primary server is available again, a new standby database can be built on this server. Dbvisit Standby can then be run as normal to keep the new standby database in synch with the primary database.
