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 Houskeeping of combination of Snapshot Backups and TSM Backups
At the moment Db2 supports housekeeping of backups by DB configuration parameters rec_his_retent and num_db_backups. These parameters are used by the customer for years for Db2 TSM backups. Both parameters are set to a value of 8 - ensuring...

Verify OVERFLOWLOGPATH is valid at the BEGINNING and allow override in RESTORE DATABASE command.
When restoring a DB2/LUW database Db2 currently restores the database and then abneds if the OVERFLOWLOGPATH is invalid. A restore can take many hours and having the restore fail at the end of the restore wastes all those hours.
