DB/DC vs. DCCTL CSA storage comparisons

The usage of resources like CSA is expected to be different between IMS in a DB/DC configuration and IMS in a DCCTL configuration. Analysis proved that some "DB" modules are currently (IMS V14) loaded also in a DCCTL environment even if not required. As an example the DL/I DATA BASE OPEN/CLOSE module DFSDLOC0 is loaded in a DCCTL environment without any apparent reason. A DCCTL vs DB/DC comparison in term of resource/storage usage needs to be considered as a possible VSCR in a future IMS version.

    Hi Gianmario,

    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 121834 is because we don't feel that much VSCR can be obtained by doing comparions of modules of DCCTL vs DB/DC environmentts, We would rather invest our resources into future items that involve moving modules / control blocks to 64 bit processing.

    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.
    Warmly,
    Deepak Kohli - deepakk@us.ibm.com
