You can achieve application HA as:
- Assign 2 queue managers to a given application
- Define queues on both queue managers
- build CCDT channel using the 2 qmgrs
- mask the queue manager names, so the app does not know the real qmgr name
- setup channel afinity etc.. to load balance between the 2 queue managers
Now when you take down qmgr 1, qmgr 2 is yet available.
during this time, traffic in transit on qmgr 1 will fail.
Otherwise, look into uniform cluster.

Is there an option to make the (non-ha) application behave HA based application so that it can connec to a queuemanager in RDQM without break should there be a failover occur.
Thanks.
