This is a quick note to self for when the password on the service account for IBM MQSeries needs to be changed. When the password expired I got an error message like this when I tried to start a queue manager:
Initialization of resource 'amqmsrvn' failed, rc=0x8000401a
The server process could not be started because the configured identity is incorrect. Check the username and password.
exitvalue = -4
I then got the resolution from here: http://ecommunity.groupintelligence.com/websphere/forums/showthread.php?t=2036
First, you need to change the service account / password on the IBM MQSeries windows service (from the Services MMC):
And second you need to go into Component Services (COM+) and find the "IBM MQSeries Services" in the DCOM Config node:
And then update the password in the "Log On" tab.
Hopefully I won't waste an hour rebuilding my queues next time!
