Hints and tips on using MSCS

This section contains some general information to help you use IBM® MQ support for Microsoft Cluster Service (MSCS) effectively.

Note: From Windows Server 2016, the new name for Microsoft Cluster Service (MSCS) is Windows Server Failover Clustering (WSFC).

How long does it take to fail a queue manager over from one machine to the other? This depends heavily on the amount of workload on the queue manager and on the mix of traffic, for example, how much of it is persistent, within sync point, and how much committed before the failure. IBM tests have given failover and failback times of about a minute. This was on a very lightly loaded queue manager and actual times will vary considerably depending on load.
