They're the number of open input and output handles on the queue.

The DISPLAY command will give you the ids.

what can be understood by an Input handle (Is it reading or writing on a queue).

Similarly what about Outputr handle..

By doing a display queue command we can know the number of IPPROCS and OPPROCS on that queue but to know which is the process what is the command..

Can we know that or is it the application guys can know about the process

It's an input handle. Guess.

Likewise guess. Or try looking them up in the documentation.

If you're not going to believe me when I tell you it's the DISPLAY command, why bother to ask?

You can find the process. What it's doing is a question for the application developers.

Maybe not so obvious to someone new and guessing. Into the q? Or into the program?

But the MQ InfoCenter will keep you from guessing. Do a search for IPROCS here:

DISPLAY QSTATUS(QName) will give you the number of threads opened that particular queue for reading or writing msgs.

IPPROCS - will tell you how many threads are pulling(reading) the msgs from that queue.

OPPROCS - will tell you how many threads are writing the msgs onto that queue.

If you want to know which PIDs are reading/ writing msgs to that particular queue, you can use the below command:

DISPLAY QSTATUS(QName) TYPE(HANDLE) ALL

you can look for the PID and grep for that PID to know which application is using that queue. You need to look for the APPLTYPE(USER) and not the APPLTYPE(SYSTEM) .

Think of a queue being like a file from an app point of view. The app will have it open for INPUT to get messages. The app will have it open for OUTPUT to put messages.

Hi bruce2359, I think Jackson32 is a bot - their reply is an identical copy on an earlier post by Sam Uppu to this thread. It should be deleted, and they should be removed. All their other posts are odd or a copy as well...
