I know I'm stupid for doing this.
I tried changing the Maxhandles for a queue manager to 1. Apparently the change took affect, but now I can't look at or alter anything on the queue manager, including the queue manager itself. I was trying to see whether have a maxhandle of 1 would only effect each thread or the combination of threads. Either way, how do I change the value of MAXHANDLES, if I can't get to the queue manager. I tried running a BATCH RUNMQSC via CSQUTIL, but it just waits indefinitely. How can I do this? I don't want to have to rebuild the queue manager from scratch.
Thanks,
Gary |

When I lock my only set of car keys inside the car...
I call a locksmith.
So open a PMR.

Doesn't this mean he's running on zOS? |

Do you have a different answer for different platforms? I'd think that regardless of the platform, the only resolution will be to stop everything that might need a handle on the QM, and then try RUNMQSC again.
This includes listeners, chins, trigger monitors, and... well almost everything else.

I would go with Jeff's approach...close down everything that is using (or trying to use) the queue manager and run your CSQUTIL again (or runmqsc depending on the platform). Remember that MQ 'takes it's own medicine' and uses the exact same API's for its channels as a users application program uses...therefore they have to also have to open a connection.
Good luck
On a lighter note....when you are finished write this on a white board and read it out loud three times

I'm on zos 1.5. Thanks for the support and reinforcement of my "stupidity". This is only a test queue manager that I use, and I was experimenting. I certainly would not have done this with a production box. So far IBM had 1 recommendation to change the initialization parameters on startup, but that didn't work. Maybe they will come up with something else.

Did you try to close down the CHIN and CICS/IMS regions that use MQ?
I would also restrict who can log on to the box while you repair it too (if possible) as they may be using the TSO ISPF interface and getting in your way.
When you tried putting the ALTER for the queue manager in the startup deck (CSQINP1) what happened?
Other than that if you aren't too bothered about any messages that may be out there how easy would it be to restore from a known good backup? |

When I made the change to CSQINP1, it didn't work. It said command cannot be issued from CSQINP1. So I tried putting it as the first statement in CSQINP2, and it worked. So I guess that is the answer. In answer to did I stop all other processes, yes I stopped everything.
Thanks for all the responses and help
