Hi,
Here is what I created.
Environment : AIX 4.3.3
MQ Series ver 5.2 CSD04
1. created user id umq01, made a member of mqm group
2. created user id umq02, made a member of mqm group
3. login as umq01 and created a QMgr QM1. Since I wanted the logs to be created in a different directory I updated the mqs.ini file and logs are created at /work/QM1/var/mqm/log
4. started the QM1 using umq01 id. and it started.
5. Similarly I created QM2 using umq02 id and the logs at /work/QM2/var/mqm/log and started the QM2 and it works fine.
6. I checked the IPCS resources using ipcs | grep umq01 and I couldn't find any, but when I tired with ipcs | grep mqm, I could see all of them.
The main idea is to isolate the shared memory of different QMGr's. Now QM1 is having problems and after I stop the QMgr I want to clear any shared memory or semaphores related to it, which I am not able to and the only way is to stop all the QMgrs including QM2 and then clear all the shared memory and start all on them.
The main reason of creating QMgrs with different user id is so that shared memory will be created by that user id. Instead all are created by mqm. Is there a way to overcome this ?. Has anyone encountered similar kind and is there a solution.
Thanks,

If all you are trying to achieve is to clear shared memories of only a particular QMGR by doing this, then I think you don't have to do this.
There is a command called amqiclen which would do this. I don't see it in the docs but if you do a search on it in this forum you will get a bunch of results. |

The owner of IPC resources created by WMQ will always be "mqm". The reason for this is all the WMQ binaries have the set User ID bit on. That means all the binaries will be run under the owner mqm irrespective of any user starting them.

Also As per the suggestion of vennela, using amqclen might no resolve your issue as I never got it working in 5.2. I am not sure if this is working better in 5.3
my $.02.
