IBM Data and AI Ideas Portal for Customers

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.

Mirror LUW Db2 history file

The RFE is to improve database integrity, backup and recovery. Db2 has a "history file" that tracks things such as backups, rollforward, log archive, etc. The history file exists in the database path (DBPATH) directory. There are two history files, db2rhist.asc and db2rhist.bak. Both of the history files are on the same file system. The history files are critical files used for database recovery as they contain information to recover the database.

My RFE is to request is to mirror the history file(s) to a different file system. The history files(s) would still exist in the same directory but could optionally be mirrored to a separate directory. If the file system or history files were lost a backup would exist on the other file system, assuming the files were mirrored. I am thinking you could create a new parameter in the database manager configuration file to enable mirroring and define the mirrored directory.
