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.

Issue different return code when no rows loaded

We have an IDAA loader job that disables the table prior to the load to IDAA. Upon successful load of # rows, Loader will end with RC = 0 and enable the table for acceleration again. If the same process is run multiple times and results in "no rows loaded" , loader will end with RC = 0 but the table is not started for acceleration. This results in queries routing to DB2 instead of being accelerated which could cause the application to experience an increase in CPU/Elapsed time. The step ends with this message "HLOU4099I 337 22:31:19.96 No data was transferred to the accelerator."

We would like to request an enhancement to loader to issue a different Return code in this scenario and consider enabling the table for acceleration when no rows are loaded.

I opened CASE TS007741616 with details of this issue that was encountered on our production IDAA system. As an interim fix we will code a step to JCL to handle when no rows loaded as this resulted in our queries not routing to IDAA.
