Re: MSCS Cluster failover problem with MQ5.3
Erik Klemetti Hi all, Thanks for all the responses, This is not a "Real" problem since the failover works. But I was concerned when failing over didn't stop the MQSeries Service as I expected, because this could be a sign of some not to obvious problem that I migth encounter down the line. Anyway I have recived several answers saying that this is happening to a lot of folks and there is no problem. Best regards Erik Hi Erik, I only have MQ 5.2 running on the MSCS cluster, not 5.3. So may be there are some differences. However, I don't understand why you concern about the MQSeries services running on the failing node. Is there a problem? When MSCS cluster vary off the qmgr from the failing node and bring up the qmgr from the standby node, the MQ services are always running and both nodes and it won't be brought down. So in my case I have 1 active and 1 passive node and the MQ services are running on both nodes all the time. Only the qmgr is running on 1 node. This is the same when you have a standalone PC installed with MQ. If you don't have qmgr running, you still have the MQ services running during start up. In my case, I have 3 processes running, amqsvc (MQ services process), amqmsrvn (DCOM) and amqmtbrn (task bar icon for MQ services) when no qmgr is up. BTW, I got the description of the processes from a spreadsheet I received from the list last year. I remembered it was prepared by Peter but not sure. I can send you that if you want but I am not sure mine is the latest or not.

Anyone out there who have experienced a similar thing or have an idea how to solve this. And if someone have an idea where I could find the descriptions to these process it would be appriciated.

Re: MSCS Cluster failover problem with MQ5.3
Here is a description of the 2 processes. I have this same setup and do not have any problems with these. amqsvc The MQ Service process. Does almost nothing except launch amqmsrvn.exe via (d)com. Normally runs under SYSTEM account. amqmsrvn The COM service process. Launched by the service process or anything else which needs it and runs under a predefined userid (Normally MUSR_MQADMIN but can be changed via dcomcnfg). Anything launched via this is effectively running as a service and can survive a logoff as they should all be running under the MUSR_MQADMIN account. Note that the processes this can launch (runmqlsr, runmqchi, strmqm) may also be launched via the command line in non-service mode.
