Backing up the broker domain on z/OS
The following instructions describe how to
back up a broker domain so that it can be restored for migration purposes
or in the event of an unrecoverable failure. You should back up, and plan
for restoration, on every system on which there is a broker or other broker
domain component. For more information about carrying out these steps, see
the links at the end of this topic.
Backing up components
To back up the components:
Stop each broker.
Note the BrokerUUID value from the following file: <broker
directory>/registry/<broker name>/CurrentVersion/BrokerUUID.
Stop the Configuration Manager.
If you plan to restore the Configuration Manager data
repository on distributed systems, take a copy of the file:
C:\Documents and Settings\All Users\Application Data\IBM\MQSI
On the other distributed platforms the directory is:
/var/mqsi
This needs to be kept with the .zip file produced
by the mqsibackupconfigmgr command,
and must be copied to the equivalent place in the restored Configuration Manager data
repository after running the mqsirestoreconfigmgr command.
Back up the Configuration Manager data repository
using the mqsibackupconfigmgr command,
or JCL job BIPBUCM.
Back up each broker database using the JCL job BIPBUDB.
Restoring components
Stop and remove the existing components in the Configuration Manager domain.
Disconnect from the domain in the Message Broker Toolkit.
Stop each broker.
Stop the Configuration Manager.
Delete each broker.
Delete the Configuration Manager.
Recreate the components.
Create the Configuration Manager repository.
Create each broker.
Restore the components.
Restore the Configuration Manager repository
using the mqsirestoreconfigmgrcommand,
or JCL job BIPRSCM.
Restore each broker database using the JCL job BIPRSDB.
Set the BrokerUUID by editing the following file: <broker
directory>/registry/<broker name>/CurrentVersion/BrokerUUID.
Start the Configuration Manager.
Start each broker.
Connect to the Configuration Manager in the Message Broker Toolkit. This re-imports the
broker topology, excluding execution groups and flows, from the Configuration Manager.
Deploy the topology configuration in the Message Broker Toolkit. This causes the Configuration Manager to give the
UUIDs to the brokers.
