Add the new broker to the imq.cluster.brokerlist property
in the cluster configuration file.
Issue the following command to any broker in the cluster:
imqcmd reload cls
This forces each broker to reload the imq.cluster.brokerlist property.
It is not necessary to issue this command to every broker in the cluster;
executing it for any one broker will cause all of them to reload the cluster
(Optional) Set the value of the imq.cluster.url property
in the new broker’s instance configuration file (config.properties) to point to
the cluster configuration file.
Start the new broker.
If you did not perform step
3, use the -D option on the imqbrokerd command
line to set the value of imq.cluster.url to the location of the cluster
