IMSLTERM sysview

[Martin Svidrnoch]

Hi, 

Is it possible to find out in sysview where are message comming from  for example BA9RATS see below.   Customer is asking us, if it's even possible to track those messages in queue to be able get rid of those. Application team is not able to find a source. So mby sysview is powerfull enough to track it.

Last time we have 4000 in queue and some tickets created because LMSGQ was over 40%. LMSGQ is 2% now so there isn’t any real problems with this.

Thanks in advance.

Hello Martin,

There's no way to determine where the messages queued to a specific LTERM originated from in SYSVIEW. You can set a threshold for metric IMLTQUE to trigger on a specific queue depth for the LTERM, or create a threshold  for the total long message queue use (IMLMSGQ%) or the total short message queue use (IMSMSGQ%). Since BA9RATS is a static terminal, a DEQALL line command from that data row on the IMSLTERM display should dequeue any messages to that LTERM.  The only other suggestion I have is to possibly search the IMS PSBLIB for the string BA9RATS to see if you can identify the PSB(s) that have a PCB specifying LTERM=BA9RATS.
