Has anyone implemented MQSI broker clones in a queue manager cluster. We have MSCS for availability but failover at around 15 minutes is too high. We are therefore considering running two identical brokers, on separate servers, with cluster queues as input to the message flows. MSCS will still be used so that if a broker stops it can be restarted on the alternative server to recover the in-flight messages. Thinking through the complexities of operation, management and maintenance is making my head hurt and I therefore wondered if anyone had tried it.
I had this problem with the MSCS where it was taking forever > 15min. There was a fix from IBM on this for the supportpac, so make sure you have downloaded the latest supportpac. You may want to contact the author as well to make sure the fix is included in the latest. I did this at the beginning of the year. I haven't put MQSI in a MQ Cluster though.
