Control-M Can be configured to support Active/Active Cluster by the use of Node Groups.

1. Install Control-M Agent on each node which can run the job.
2. Create a Host Group (Node Group in Version 7) from the CCM which conatins all of the agents which can run the application.
3. Schedule the jobs to the Hostgroup

There are 2 ways to handle when a node goes offline or comes online:

1. Make sure that the agent stops when the application is taken offline. This will remove the node from the Hostgroup and prevent new submissions to tihs node. The downside if you cannot access SYSOUT on this node till it is available again.

2. When the Application goes offline remove the agent from the Hostgroup using the ctmhostgrp command (ctmnodegrp in v7) on the agent. This utiliy is documented in the Control-M Utility Guide.

ctmhostgrp -EDIT -HOSTGRP <hostgroup name> -APPLTYPE <application> -DELETE <hostname>

When the application comes online add the hostgrp back:

ctmhostgrp -EDIT -HOSTGRP <hostgroup name> -APPLTYPE <application> -ADD <hostname>

* for Control-M v7 replace ctmhostgrp with ctmnodegrp
