Hi guys, This is not a problem itself, but I would like to know why this happens, maybe this has happened to any of you.
Some consumer applications (I dont have access to them or their code  ) dont increase the Open Input Count value in the queues when they connect. I tried setting MONQ(HIGH) also checking the queue status as TYPE(HANDLE) but they dont show up, even while they are actively consuming.
I was wondering if there is any type of call in the application programming that might cause this behavior.
Again, this is nitpicking a minor issue but I would like to figure out why.
Thanks in advance. |

They open the queue, get the message and close the queue. That happens so fast that you just haven't been lucky enough to issue your command to display open input count at the exact milliseconds they OpenThenGetThenClose.
No, there is no way to get a message from a queue that is not open for gets.

As Mr. Potkay suggests, likely, the entire sequence of connect, open, get/put, close, disconnect, took a few microseconds.
For your amusement, you could run an mq trace on the app to see this interesting behavior.

You could switch statistics and accounting on for this queue.
