Error Upgrading to 8.1.8.0

I performed an upgrade today on a server going from 8.1.0.0 to 8.1.8.0 and after the upgrade we encountered the following errors in the actlog as the system was starting.

Although the server started, I wanted to make sure this would not cause issues with the instance. I searched the error ANR9999D_2835836899 and found the following IBM APAR notice. It appears that after the upgrade you may have to manually upgrade the DB2 version using the DB2 update tool. While it appears to be a minor issue, I would recommend you check your instances after upgrade to verify whether you need to run the manual steps to resolve the errors. I've included them here for your convenience.

NOTE: I've added a couple commands (in bold) that we have had to add to the process to make it work.

Local fix

Even though the db2-level might be updated to the latest version 11.1.4.4, run the below set of commands
Stop TSM server and issue the following commands as the instance owner.
  • db2 start
  • db2 force application all
  • db2 terminate
  • ipclean

login as root user and run
  • /opt/tivoli/tsm/db2/instance/db2iupdt -d <instance name>

login as the instance owner ID and issue the command:

  • db2updv111 -d TSMDB1

This issue is supposedly fixed in version 8.1.9.0 and higher.
