Hello!
I've run into a problem with MQ in our Prod environment where only 1 instance of RUNMQSC is being allowd to run at a time. I do not see this behavior in our development environment. Is this a configuration or licensing issue? We have multiple queue managers running and should be able to run that command more than just a single time.
Thanks in advance for the help. Please let me know if you need further information from me.

I never faced this restriction.
Maybe they have put a wrapper in your environment to restrcit multiple runmqsc's to prevent more than one person using it.
Can you do a which on runmqsc and see if it is the native runmqsc that you are invoking. |

Thanks for the reply.
Both our Dev and Prod MQ installations are using the same runmqsc program ("which runmqsc" generates the same result on both - /usr/bin/runmqsc).
Here is an error I found in the AMQERR01.LOG file (found in /app/mqm/errors/ directory):
11/15/04 11:26:46
AMQ6119: An internal WebSphere MQ error has occurred ('28 - No space left on
device' from semop.)
EXPLANATION:
MQ detected an unexpected error when calling the operating system. The MQ error
recording routine has been called.
Does this make sense to anyone?

| It sounds like you are on a Unix system that requires configuration of the kernel parameters and one of your semaphore values is probably too low. There are recommended values given in the Quick Beginnings manual. |

Yep, that's the same conclusion my UNIX admin came up with. We definitely have a resource issue.
Thanks for the info!
