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 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.
Daimler needs support of btrfs on Db2 11.1 on SLES 12 SP3. result of IBM PMR (Case TS000138704): â€œAlthough the DB2 documentation only lists recommended file systems, support for unlisted file system might be limited and there is no guarantee that DB2 will work with it. Whether it is not supported or not tested would mean that it can generate an error on your machine in certain phases.â€
https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.1.0/com.ibm.db2.luw.admin.dbobj.doc/doc/r0056470.html BTRFS is not listed, therefore it is not recommended. Technote swg21978698 covers installation of Db2 on BTRFS (in our blueprint: /opt/IBM/db2), which has already known issues. http://www-01.ibm.com/support/docview.wss?uid=swg21978698
Even we at Daimler are currently discussing root filesystem (â€œ/â€) and we basically do not use the root filesystem for DB2 (no installion, no data container), root fs is still used: - in installation which uses /tmp => solution: we could define /tmp as separate filesystem - by any kernel call (forking process , performing I/O) Setup layout at Daimler on SLES: /opt/IBM/db2 xfs Installation directory /srv/db2/home xfs Instance home directory /srv/db2/var xfs dumpg directory /srv/db2/data1 xfs Data$Index tablespace container directory /srv/db2/temp1 xfs Temp tablespace container directory /srv/db2/evmon xfs Event monitoring directory /srv/db2/onredop xfs Logpath /srv/db2/onredom xfs Mirrorlogpath /srv/db2/offredo xfs Archive log path for emergency /dbshare xfs Application related data /free_SOD xfs Free Storage to sue on demand / ??? OS root filesystem Default Filesystem of "/" (root fs ) is btrfs, but it is not supported by Db2!
