Applying fix packs


It is recommended that you keep your DB2® environment running at the latest fix pack level to ensure problem-free operation. To install a fix pack successfully, perform all of the necessary pre-installation and post-installation tasks.

A DB2 fix pack contains updates and fixes for problems (Authorized Program Analysis Reports, or "APARs") found during testing at IBM®, as well as fixes for problems reported by customers. Each fix pack contains an APARLIST.TXT file, which describes the fixes it contains.

Fix packs are cumulative. This means that the latest fix pack for any given version of DB2 contains all of the updates from previous fix packs for the same version of DB2.

The fix pack images available are:


For non-root installations on Linux or UNIX, root-based features (such as High Availability and operating system-based authentication) can be enabled using the db2rfe command. If root-based features were enabled after installing your DB2 product, rerun the db2rfe command each time a fix pack is applied in order to re-enable those features. For details, see the non-root related links below.

On Linux or UNIX operating systems, if national languages have been installed, you also require a separate national language fix pack. The national language fix pack can not be installed alone. A universal or product-specific fix pack must be applied at the same time and they must both be at the same fix pack level. For example, if you are applying a universal fix pack to non-English DB2 database products on Linux or UNIX, apply both the universal fix pack and the national language fix pack to update the DB2 database products.

If you have multiple DB2 copies on the same system, those copies can be at different version and fix pack levels. If you want to apply a fix pack to one or more DB2 copies, install the fix pack on those DB2 copies one by one.

To install a fix pack:

  1. Access and download the latest DB2 fix pack by selecting the link for fix pack downloads from the DB2 Support Web site at

  2. Check fix pack prerequisites, and perform the necessary tasks prior to installing a fix pack. If you already have DB2 database products installed, also stop various DB2 processes. See the fix pack Readme for details.

  3. Choose a fix pack installation method and install the fix pack.
Check the log file for any post-installation steps, or error messages and recommended actions.
