Improve IMS performance for DLI calls that hit empty areas.

Improve IMS performance for DLI calls that hit empty areas. By “empty “ we intend to mean - areas that have no data populated in them since allocation , OR an area that had some data but it was deleted and is now empty. And this should target process - either batch or online and not be limited to a SETR card.

Performance Degradation with empty areas is usually observed when range based lookup is done.

DLI call was provided with the Initial Case, pasted here again. In this example we expect IMS to return “GE” fast enough.

EXEC DLI GU USING PCB (DBDAMK3-PCB-NUM)
SEGMENT (AMSFH00)
WHERE (AMFFH00K >= WS-FH00-LOW-KEY AND
AMFFH00K <= WS-FH00-HIGH-KEY)
INTO (FH00-SEGMENT)
END-EXEC

We want acceptable performance in both batch and online – Card uses BMP for both batch and online.

    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. We think it’s a great idea but we are rejecting RFE 138793 because 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.
    Thank you.
    Sincerely,
    Deepak Kohli - deepakk@us.ibm.com
