Restoring data

If a disaster occurs in the primary data center, you can continue to provide business support if you have a valid backup. You restore the backup to the secondary data center and then verify the restored data.

Restoration is the process of rebuilding all or part of a backup to the corresponding secondary environment, as shown in Figure 1:

Figure 1. Restoration process

Important: To ensure the consistency of all data, the restoration must occur for the whole cell and underlying database.


Procedure

To restore the production environment to the secondary environment:

  1. Reinstall the installation data, including the IBM BPM installation data and the IBM Business Monitor installation data.
  2. Reinstall DB2 and create the DB2 instance.
  3. Restore the configuration data to all servers from the backup configuration data.
  4. Restore the runtime data to all servers by replicating the backup runtime data.

  5. Perform changes that are specific to the environment.

    For example, update the host name to reflect the secondary environment, or change the data source configuration to point to the secondary database.

  6. Validate the connectivity to the resources outside the recovery scope.

  7. To restart the environment...

    1. Start the database server.

    2. Start the dmgr and node agents.

    3. Start the message servers of IBM BPM.

    4. Start the support servers of IBM BPM.

    5. Start the application servers of IBM BPM.

    6. Start the message servers of IBM Business Monitor.

    7. Start the support servers of IBM Business Monitor.

    8. Start the application servers of IBM Business Monitor.
  8. Verify the restored environment and determine whether it is valid.
  9. Recover inflight transactions.
  10. Redirect load to the new environment.

    You can typically set the same host name and IP address for the secondary environment as for the primary environment. This step depends on your backup policy.
