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.
Enable customers running 24/7 to create unique indexes
Our Internet and Mobile applications are used 24/7 and we do not have any batch windows nor any maintenance windows.
When creating new indexes on existing tables the a CREATE INDEX operation generates an unwanted outage when created with DEFER NO.
To avoid the outage you would like to use DEFER YES which defers the index build until a REBUILD INDEX utility execution. This works perfectly well for an index that is not defined as UNIQUE. For a UNIQUE index it is put into Rebuild Pending status which in turn means that the data cannot be read or updated with SQL until the index is rebuilt. An SQLCODE-904 will be returned to applications trying to access the table independent on access path.
