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.

db2pd command to report exact operation that causes HADR replay only window
Currently only "Replay only window is active" is reported in db2diag.log, but not the detailed information about the operation that causes the replay only window, such as exact DDL, reorg, runstats, and etc. statements.
aï¼‰HADR replay master contends with replay worker on queue, and lots of latch contention were observed.bï¼‰HADR replay has IO performance issue. Lots of random IOs were observed, and there should be some sort of prefetch IO to improve performance.
