Hi Matt,
Thank you for the details.
I used Camel-Integration as I realized true clustering is not possible between
IBM MQ and ActiveMQ.

The full repository QMGR (MFQMGR) is on Mainframe IBM MQ (remaining as-is).
There are two QMGRs on Linux which are being migrated to ActiveMQ (A & B).
I configured the connectivity between MFQMGR and A using camel integration. Now
I need to configure B to become part of this group. This should look like my
existing configuration in terms of functionality. What would be the approach
here?
Here is how my existing configuration (names changed)
dis clusqmgr(*)
4 : dis clusqmgr(*)
AMQ8441I: Display Cluster Queue Manager details.
CLUSQMGR(MFQMGR) CHANNEL(TO.MFQMGR)
CLUSTER(MyCluster)
AMQ8441I: Display Cluster Queue Manager details.
CLUSQMGR(A) CHANNEL(TO.A)
CLUSTER(MyCluster)
AMQ8441I: Display Cluster Queue Manager details.
CLUSQMGR(B) CHANNEL(TO.B)
CLUSTER(MyCluster)
Thanks & Regards,

Hi Rohini-
ActiveMQ is a great option to migrate from IBM MQ. For many use cases, there is
little to no coding change required to applications (other than the connection
factory swap out).
ActiveMQ supports store-and-forward clustering (IBM MQ-style), and also
on-demand consumer driven (better for running cloud/Kubernetes where you may
want to scale your cluster). These two approaches can also be combined to
support really cool topologies =)
Migration is usually very straight forward!
Thanks,
Matt Pavlovich
