Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Lower CPU consumption in CDC for Db2 z/OS (local capture): Modify IIDR CDC for z/OS to reduce its priced general CPU consumption by moving some consistent CPU processing to zIIP

This Request for Enhancement is to modify IIDR CDC for z/OS to reduce its priced general CPU consumption by moving some consistent CPU processing to non-priced zIIP eligible processing. IIDR CDC is a large general CPU consumer in our shop resulting in a high cost of ownership and an inhibitor to more CDC exploitation. During the month of July CDC was the highest CPU user at 15.34% of our MSUs for the LPAR it ran on during the day's peak.

    Yes, we know about the "CDC Replication Engine for Db2® for z/OS® Remote Source" product but this is no solution (not useable) for IIDR CDC customers like us who use IIDR CDC to replicate data from Db2 for z/OS to Db2 for z/OS. So, pls. consider to make the IIDR CDC for z/OS workload zIIP eligible. Thank you.

    This looks to be what you're looking for :

    The CDC Replication Engine for Db2® for z/OS® Remote Source is a new replication engine for IBM® Data Replication as of version

    This engine provides full source-side replication capability for Db2 for z/OS with a minimal footprint on z/OS. The replication engine is installed on a distributed platform (Linux, UNIX, or Windows) and after initial setup is entirely administered and maintained on that platform.
