Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. 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.

Avoid Single point of failure for Db2's critical files

If the critical files of Db2 damage, e.g. by erroneously deletion, file system corruption Db2 will no longer be available (#usable). Since some of the critical files are permanently updated a restore of the critical files does solve the problem. A loss of (part of) the local database directory requires a complete restore of a database which means hours of outage.

Mirroring the local database directory to a different path (preferably a different file system) could make Db2 tolerant to such kind of problems. This kind of enhancement could work roughly comparable to MIRRORLOGPATH, which allows to configure a mirror path for the log files, a DB parameter like DBDIRMIRRORPATH could allow to specify a mirror path for the local database directory

SQLOGCTL.LFH.1 and SQLOGCTL.LFH.2 in different directories(RIMS)

SQLOGCTL.LFH.1 contains very important log control file infos, and therefore has a redundant copy named SQLOGCTL.LFH.2 . However, both files always reside in the same directory. An option is needed, to configure a second directory/path, so that bo...
