How to Recover from a Disaster

If a production system failure occurs, the endpoints work against the disaster recovery environment. When you recover from a disaster, you move operation from the disaster recovery environment back to the restored production environment.

The following process describes how to recover from a disaster:

1. Stop CA ControlMinder on the production Enterprise Management Server and the production Distribution Servers.
2. Stop all administrative work against the disaster recovery DMS, that is, stop CA ControlMinder Enterprise Management and the policydeploy utility.
3. (Optional) Auto-truncate the updates.dat file.
4. Back up the disaster recovery DMS. You can back up the DMS using either of the following methods:
   • local backup
   • remote backup
5. Restore the production database (RDBMS).
6. Restore the production DMS from the disaster recovery DMS backup files.
7. Start CA ControlMinder on the production DMS.
8. Back up the production DMS.You can back up the DMS using either of the following methods:
   • local backup
   • remote backup
9. Restore each production DH from the production DMS backup files.
10. Start CA ControlMinder on each production Distribution Server.
11. Move all administrative work to the production DMS, that is, start CA ControlMinder Enterprise Management and the policydeploy utility on the production CA ControlMinder Enterprise Management.
12. (Optional) If the disaster recovery DMS is out of sync with the production DMS, complete the following steps:
    1. Restore the disaster recovery DMS from the production DMS backup files.
    2. Back up the disaster recovery DMS.You can back up the DMS using either of the following methods:
       • the sepmd utility
       • selang commands
    3. Restore each disaster recovery DH from the disaster recovery DMS backup file.
