We are z/OS 1.9, MQ 6.0.

We collect all type 115 & type 116 SMF records for our MQ systems and I am running the support pack (MP1B) sample programs but I am getting some strange results that I am having trouble understanding.

I have actually sent a question to IBM about this but thought I would ask it here too.

On the MQGET stats I understand the disparity in the MQGETs can be caused by wait intervals popping without a message available (2033 reason code). This is not at issue, but what I don't understand is that in these circumstances, even after a valid MQGET is registered the bytes transfered is 0. Now I understand that 0 length messages are possible, but I really doubt this is happening 'across the board'.

Also we don't see any bytes transfered for any dynamic queues....but this could be because of the issue above.

We also see an awful lot of 'non productive' MQGETs for our workflow queues...about one every 20 seconds but we are following this up elsewhere.

Has anyone got any thoughts on why this is happening?
