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.

New db2diag.log message to indicate when an optimizer plan is missed due to missing temp tablespace(RIMS)
(See Discussion entry for full details) When an optimizer plan is ineligible due to the non-existence of a sufficiently large temporary tablespace (ie. sort is unable to handle the width of workload row size), a db2diag.log message should be writt...
Optimizer should account for bufferpool hit-ratio when estimated page access time.(RIMS)
In PMR 00962,7TD,000, Goldman Sachs had a scenario where optimizer was choosing a more expensive HSJN over a less expensive NLJN. Shu Lin summaries the problem well: 'In terms of CPU cost and number of IOs, we correctly estimate that NLJN is bette...
