Move DLI OSAM and VSAM control blocks above the bar

There are many OSAM and VSAM storage control blocks that are currently stored below the line.
The use of HALDB databases and number of databases datasets defined to IMS is always increasing. HALDB also requires additional dataset to cater for Secondary indexes compared to a standard database.

The current design poses a limit on the number of database that can be defined to a single IMS because of the limited amount of below the line storage available.

We are currently looking at converting large databases that do not require OSAM sequential buffering to VSAM as we have noted slight relief in doing so.

Even though there is some relief of PVT storage in V15 moving the control blocks above the bar would completely remove this limitation.

    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 close / reject it. We think it’s a great idea and we have placed this on our futures road map. We are closing RFE 125210 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. But we have placed the item on our futures roadmap.

    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
