Preparing to install a fix pack

In order to install a fix pack, you must first download and extract the fix pack. You must also stop the Db2® instances that you plan to update to the new fix pack level.

Before you begin

If a IBM® PowerHA® SystemMirror® for AIX® cluster is running, you cannot perform a IBM Tivoli® System Automation for Multiplatforms (SA MP) installation, upgrade, or update because SA MP bundles Reliable Scalable Cluster Technology (RSCT) file sets that are dependent on PowerHA SystemMirror. You can skip the SA MP installation when you install a fix pack. For information about installing or upgrading SA MP using a PowerHA SystemMirror cluster, see the white paper entitled Upgrade guide for Db2 Servers in HACMP Environments, which is available from the IBM Support and downloads website (

Remember: If you have IBM Tivoli Composite Application Manager Agent for Db2 (version 7.1) installed, you must first stop the DB2 Agent of the Tivoli Composite Application Manager before you can update to a new fix pack. After the fix pack installation, you can restart the DB2 Agent. For more information, refer to DB2 agent 7.1


To prepare to install a fix pack:

  1. Check the fix pack prerequisites.
  2. Get the fix pack.
  3. Extract the fix pack.
  4. Optional: Reduce the size of the fix pack.

    You can use the db2iprune command to reduce the size of your Db2 fix pack installation image. Before installing a pruned fix pack, you must ensure that the pruned fix pack image contains at least the same components that are in the Db2 copy. If you prune too much from the fix pack image, the fix pack installation fails.

  5. If you already have Db2 database products installed in the selected installation path:
    1. Optional: Back up your current configuration and diagnostic information.

      Gathering diagnostic information might be helpful when you are about to install a fix pack. This information will help to diagnose any problems that might arise after the installation.

      See Backing up DB2® server configuration and diagnostic information.
    2. Perform one of the following actions:
