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.

Request for RUNSTATS SHRLEVEL REFERENCE with SAMPLE to update RTS TOTALROWS
Recovery to PIT or to current, and non-standard recovery methods such as DSN1COPY or DF/SMS dataset DUMP/RESTORE from flashcopy backups can leave TOTALROWS set to 0, NULL or invalid values. Trying to run something like a REBUILD index relies on TO...
