Add parameters related to logging and CHKW calls for USERMOD elimination

We have a USERMOD in place for IMS V15 related to performance. This USERMOD was originally put in place for logging performance issues in our environment related to high volume BMPs causing logging delays and holding up the BMP and online environments.

It makes adjustments to these modules as follows:

Module DFSFDLS0 is being updated to change the log timer task from 250ms to 50ms, field LMTINTVL.

Module DFSFDLD0 is being updated to change the constant so the log timer task writes out log records waiting 10ms versus 100ms, field
LCDWTHRS.

We are requesting that these values be made available through parameters (e.g. DFSPBxxx).

It would be ideal if there was a type-2 command to change the parameters while IMS remains up.

    Hi,

    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 115282 is the following: We are certainly evaluating this item as part of our scalability futures roadmap, however, we don’t feel we can deliver it within the next 18-24 months which is the goal we have set for RFE deliverables as part of our IMS Gold program. You are welcome to resubmit this RFE at a later date and we will reconsider.

    We appreciate your input to IMS, and we hope that you will continue to submit ideas for improvements as customer feedback is a key component to shaping the future direction of IMS.

    Adding the actual usermod source.

    ++SRCUPD(DFSFDLS0) DISTLIB(ADFSSRC)
    /* CHANGE SLEEP TIME FOR LOG TIMER TASK FROM 250MS TO 50MS
    TO SPEED UP WAITWRITES FOR FASTPATH AND IMSDC*/.
    ./ CHANGE NAME=DFSFDLS0
    * MVC LMTINTVL,=F'25' SET STIMER INTERVAL =.25 SU00013 03471000
    MVC LMTINTVL,=F'5' CHANGE STIMER FROM 250MS > 50MS SU00013 03471100
    ./ ENDUP
    ++SRCUPD(DFSFDLD0) DISTLIB(ADFSSRC)
    /* CHANGE WAIT CONSTANT SO LOG TIMER TASK WRITES OUT LOG
    RECORDS WAITING 10MS OR LONGER */.
    ./ CHANGE NAME=DFSFDLD0
    * MVC LCDWTHRS,TENTHSEC SET 0.1 SEC WTWT INTERVAL SU00013 01700000
