Backing up the broker domain on z/OS

These steps tell you how to back up a broker domain so that it can be restored for migration purposes or, in the event of an unrecoverable failure. The backup and restoration of a broker needs to extend to every broker that is deployed to by the Configuration Manager. All the topics that you need to carry out these steps are listed in the 'Related information' section at the end of this topic.
To back up the components:
  1. Stop each broker.
  2. Note the BrokerUUID value from the following file: <broker directory>/registry/<broker name>/CurrentVersion/BrokerUUID.
  3. Stop the Configuration Manager.
  4. Back up the Configuration Manager data repository using the mqsibackupconfigmgr command, or JCL job BIPBUCM.
  5. Back up each broker database.

To restore the components:

  1. Stop and remove the existing components in the Configuration Manager domain.
    1. Disconnect from the domain on the Message Brokers Toolkit.
    2. Stop each broker.
    3. Stop the Configuration Manager.
    4. Delete each broker.
    5. Delete the Configuration Manager.
  2. Recreate the components.
    1. Create the Configuration Manager repository.
    2. Create each broker.
  3. Restore the components.
    1. Restore the Configuration Manager repository using the mqsirestoreconfigmgr command, or JCL job BIPRSCM.
    2. Restore each broker database.
    3. Set the BrokerUUID by editing the following file: <broker directory>/registry/<broker name>/CurrentVersion/BrokerUUID.
    4. Start the Configuration Manager.
    5. Start each broker.
    6. Connect to the Configuration Manager on the Message Brokers Toolkit. This re-imports the broker topology, excluding execution groups and flows, from the Configuration Manager.
    7. Deploy the topology configuration on the Message Brokers Toolkit. This causes the Configuration Manager to give the UUIDs to the brokers.
