dr-recover

The dr-recover command is normally executed from the Backup-A appliance, but in the event that Backup-A is off-line, may be issued from Backup-B.

dr-recover

This command will only be successful if the production site is inactive or unreachable.

When called, dr-recover does the following:

Verify the production site is inactive.
Verify connectivity to Backup-B.
Synchronize with the most recent snapshot from the production site. Synchronization erases all prior EMS server data from the backup site and overwrites it with the server data from the production site snapshot.
Synchronize with Backup-B.
Activate TIBCO Enterprise Message Service™ services.
Verify that EMS instances on Backup-A and Backup-B are fully operational.

Should one of the Backup appliances also be down, the available backup appliance can be recovered in single appliance recovery mode.
