Yup, we work 'together' in the sense that we are working on the same problem. Two different companies, two different locations. Same machine, same problem.

That's the long answer

Hi,

This completely sounds like the account MQ is running under is incorrect.

Go to the component services snap-in under control panel/administrative tools. Or do start, run, dcomcnfg.

Look under Dcom Config section for IBM MQ Services, right click properties. Click on identity tab. Check account has correct privileges - test with local admin account to be certain.

Alternatively run the prepare Websphere MQ wizard from the start menu which allows you to specfiy the account there also.

Also make sure you are not using the command line STRMQM command - under windows it will be started as the current user. Use the Websphere MQ Explorer to start the queue managers - this way ensures the QM's are being started as the account specified above.

Good luck

This may not be clear from the posts above, but the queue manager will start up and run for periods of time (sometimes days), before shutting down.

I would have expected an account or permissions problem to manifest immediately at start up.

Yes, I read that.

Unfortunately in Windows you can start the queue managers up using STRMQM or with an incorrect account and it will work fine, then you logout and the QM is asked to perform some work maybe hours or days later and will then fail. I have a list as long as my arm of other Windows specific MQ funnies that i don't get on other platforms.

cheers

Right now that looks to be the issue. The identity is set to The Interactive User. I'm working on getting a userid built and used.

Thanks for the help.

Interactive User will mean any process started in MQ will fail at some point after that user has logged out.

Cheers

Do we need to shutdown & restart MQ for this to take effect?

If you change the user using DCOMCFG or by rerunning the Prepare MQ Security wizard, then you need to restart the IBM MQ Service - not just the queue manager.

And it's probably better to restart the whole machine.
