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.
Introduce a new parameter to the export utility to be able to export data from a table that is in a backup image.This functionality is especially useful for data extraction without touching/impacting the source system

Inplace Reorg should be allowed on a table with an Expression Based Index
Expression Based Indexes (available since V10.5) are a great feature that can improve query performance without adding a new (generated) column and modifying existing code. But, you cannot do an Inplace Reorg on a table with an Expression Based In...
Provide a documented and supported procedure to generate ddl (db2look as SP - like db2lk_generate_ddl)

use of wildcards for table selection with REORG,RUNSTATS etc
Certain utilities that most of the time operate on a (sub)set of tables like REORG and/or Runstats would be much easier to operate if the set of tables to be processed could be selected by means of wildcarding. The wildcarding should be enabled on...
