Would anyone know how CICS applications using MQ have resilient ability?
Can CICS connect to a share queue group instead of a explicit queue manager?
Can clustering help without a single point of failure if I do not have sysplex? |

Yes and no, WebSphere MQ is very stable, and it lives together with the OS.
Some of my customers are running in monoplex, they don't consider clustering/shared queues, because they don't get any benefits from it.
I haven't seen bottlenecks in MQ, where a cluster/shared setup would help on a monoplex. And about resilience, you will still have a single point of failure what ever you do... a disc failure, powerfail, operationsfail etc.
So in this case my personally oppinion it's the end user application that is causing most problems regarding in a production environment (developers say they are tested but we know better, we see the ASRA abends...)
Just my $0.02
