Hints and tips on using MSCS

 

This section contains some general information to help you use WebSphere MQ support for MSCS effectively.

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, that is, how much of it is persistent, within syncpoint, how much committed before the failure, and so on. In our test we have seen 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.

• Verifying that MSCS is working
  

• Using the IBM MQSeries Service
  

• Manual startup
  

• MSCS and queue managers
  

• Always use MSCS to manage clusters
  

• Working in Active/Active mode
  

• PostOnlineCommand and PreOfflineCommand
  

• Using preferred nodes
  

• Performance benchmarking
