Hello All,
we have a problem in our support project architecture. We found one xmitq curdepth is increasing. We checked for channel but no channel is using it.
this Xmitq is created with the source qmgr name only.
Someone help me why an xmitq created like that and under use. |

| Someone is using the name of the queue manager to address messages. That's why they're getting put to the xmitq. |

Look at the connection handles on the queue, find out what process has it open for writing.
Something is addressing messages using the name of this xmitq as either the name of a queue or the name of a queue manager.
See if the messages on the queue have a transmission header on them. If they do, you know it's because someone is trying to use the name of the queue as the name of a queue manager. If they don't, it's because someone is using it as the name of a queue. |

We couldn't check the QSTATUS for finding the processes connected. i think xmitq never let us see the handles 
checked the header and it started with XQH but not sure who is keeping these msgs and who created this queue without channel association. |

An XQH tells us that the app mqopened a QRemote definition. Look for the original MQMD and application data in the xmitq.
You could put disable the xmitq, then wait for someone to call to complain.

Or they didn't use a Remote Q definition but instead supplied both the destination QM and destination Q in the MQOPEN / MQPUT1.

The source QM? The XMITQ on QM1 is called QM1? Or did you mean the destination QM?

Ooooh, ooooh!
Does the qmgr object default xmitq attribute specify an xmitq name? And is that name also the same name as the qmgr?

A message in an xmitq should contain an XQH (with its own MQMD), and your original application-created MQMD and application data.
Display a few complete messages from the xmitq (with amqsbcg, or equivalent). You may suppress proprietary application data - we don't need to see that.

In addition to what bruce requested...
What is your exact QM name?
On this same QM, what is the exact XMITQ definition that you are questioning? Post the whole definition from a runmqsc command.
What you have said so far is the QM name is something like APPLE, and you are saying the XMITQ on the APPLE QM is aslo called APPLE, and that it has been like this since 2010, and things have been fine. This cannot be.
