Questions on Data Server Manager and Db2 Edition?

Data Server Manager or DSM has come a long way and is now the tool of choice for many companies for managing Db2. I get a lot of questions on how to get it and what Db2 editions are supported. Check out Peter Kohlman’s info here and you should find what you need.

Db2 Version and OS Requirements

I have lots of clients running Db2 on Windows Server 2008 R2… End of Service for Windows 2008 R2 is 1/14/2020. Db2 11.1 and above requires Windows 2012 Standard Edition or above so if you are running a Db2 10.5 on Windows Server 2008 R2 you should be making plans to upgrade to Db2 11.1 and Windows Servers 2012 Standard Edition or preferably Windows Servers 2016 Standard Edition.. Get the details for all of this at the below links:

Db2 11.1 Mod 4 Fix Pack 4

This fix pack was released on 27 Nov 2018 so it isn’t new but it has some enhancements worth moving to and exploiting. Reads on standby has been improved via reduction in replay window thru a the new  variable DB2_HADR_ROS_AVOID_REPLAY_ONLY_WINDOW.  The DB2_USE_ASYNC_FOR_MIRRORLOG variable can be used to improve mirror logpath performance by enabling log writing in parallel to the active and mirror log path.  The performance of online backups can be improved by using the new DB2_REDUCE_FLUSHING_DURING_BACKUP registry variable by reducing the amount of changed pages that have to be flushed from the bufferpool at online backup startup.

There are a bunch more of improvements, get all the details here:

Db2 Continuing Support

I get a lot of questions regarding whether or not a clients Db2 version is supported or other questions on extending support. IBM announced the Db2 continuing support program quite some time ago. For a refresher, go to this page
