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 an idea
Upvote ideas that matter most to you
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.
DB2 does not identify the tables as collocated even though they exist on the same set of db partitions because they reside in different database partition groups. The optimizer doesn't always make a good choice when comparing plans in DPF.
With the improvement to the block index access cost (introduced in the APAR IT00482 ) , our scenario/statement is exposed to errors in the cardinality estimates and a limitation in DPF plan comparison, as well.
