Hi All,
I m facing a probleM on AIX 5.1 using MQ5.3.When my program is trying to pick up the message from the local Queue i m getting an error with reason Code 2102.Though the reason code suggests that system resources are full i find no such problem.
Can anyone suggest me what exactly is meant by System Resource problem or whether it is any other problem.Thx in advance |

This maybe related to your memory segment. Are you also doing DB connect with your application? There is a topic in the Quick Beginings guide on extending the memory segment on AIX. Check that out if it is related.

By default, AIX has a different System V Shared Memory model from the other UNIX platforms. No more than 10 shared memory segments can be attached simultaneously by an individual process.

The types of situations that can increase the number of segments that WebSphere MQ tries to attach are:
v Many threads all attach to WebSphere MQ
v Large messages transfer between the application and WebSphere MQ
v An application uses other application libraries, such as database connections, and these other libraries allocate shared memory from the 10 slots available.

| I thought the memory segment problem was in 5.2? |

| An app MIGHT still run into shared memory limitations, unless it sets EXTSHM=on in the environment first. Which is fully described in the books. In any case, I'd expect an FDC to give more details that pointed to the root cause. |
