IMS LOG56FA Field TPMGU=1 after a LOG08 created

In the record x'56FA' of the LOG, the field TPMGU=2 after the creation of a LOG08. Even if the region is in PWFI and that the LOG08 is created because of the PLCT.
So we can't use the field TPMGU to count the number of messages processed.

    Hi Alain Arnulf,

    Thank you for your interest in keeping IMS a vital and successful product. Software development has continuously evolved during IMS's lifetime, and so has IMS itself. We have kept pace with, adopted, and implemented many industry standard best practices within our organization, including Continuous Delivery, Design Thinking, and Agile.

    When choosing new features to add from the list of requirements in our backlog, we assess which will bring the most value to as many clients as possible and prioritize those.

    At this time, after reviewing this request for enhancement and assessing its potential value, we have decided to reject it. The reason we are rejecting RFE ID 103677 is because it is not recommended to use the TPMGU field to count the number of messages processed by the application. Instead, we strong advise customers to use the field DLRMCNT in the 07 Log Record because that is the field that indicates the number of messages actually processed by the application during the last schedule. The TPMGU field is meant to indicate the number of GU calls issued against the message queue. A GU call could result in a QC status code being returned to the application instead of an actual message. So, a one-to-one correlation does not exist between the number of GU calls issued by the application and the number of messages actually processed by an application.

    If you have any further questions - please let us know.

    Thank you.
    Haley Fung - hfung@us.ibm.com

    1) Yes we had opened the PMR 51448,661,706.
    2) Our metrology tool use only the LOG56FA and not the LOG07.

    Don't you think that it's not logic that the field TPMSG is at 2 at each PLCT value, even if the application don't receive a Status Code QC ?

    Hello.
    This is Carlos Alvarado from IBM and I am currently looking at your RFE and I have a couple of questions.
    We are trying to better understand this particular RFE.

    1- Have you opened a PMR to have our Support personnel look at the contents of the x'56FA' log records and were told to open an RFE?
    2- Have you looked at the x'07' log record "DFSLOG07" for application level statistics?
    ie: "DLRGUMES DC F'0' NO OF MSG QUEUE GU CALLS"
