Is there an easy way to determine what percentage an individual Queue's messages is consuming of a Pageset's storage? I have a pageset which has expanded to its maximum, and dozen of queues have messages in them. I'm trying to figure out which queue is taking up the lion's share of the pageset space so I can contact the developers about getting the messages off the queue.
This is for MQ for z/OS 6.0 running on z/OS 1.9, in a "clone of PROD" testing environment for the developers. |

Try this: DISPLAY USAGE(PAGESET)
Then work backwards. Identify which PSIDs map to which STGCLASSes; and which DEF QLs map to which STGCLASSes.

Thanks Bruce. We are using TMONMQ and it shows which queues are in a given Pageset. The problem is that a Pageset filled up and about 20 queues in it have thousands of messages. Given that a queue can have variable length messages, I can't just look at depth and multiply by MaxMsgLength.
I was trying to see if there is an easy way to determine which percentage of the Pageset space a single queue is occupying. It doesn't sound like there is.
Thanks for responding. |

Hi, Phil.
SMF statistics and accounting records will be your solution.
Take a look at the WMQ z/OS System Setup Guide, "Using Performance Statistics."
I would have thought TMON able to consume and report the number and size of messages get/put.
I seem to recall that you have/had MXG. True?

well, or you have a browse program that loops over the queues with messages, browses all messages and accumulates their size, then you can compute the size used within the pagesets ....

I would have thought this wheel already invented.
