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.

Limit the number of tape drives allocated when using a TEMPLATE with STACK NO specified
In our reorg utilities against lobs using inline image copy it is required to use STACK NO, however, since we image copy to tape it causes the DB2 utility to acquire multiple tape drive units all at once for each partition of a UTS. This is an iss...
