DB2 product updates are through fix packs (also known as FixPaks, patches, updates, or PTFs). Some fix packs can be applied to any level of a DB2 installation, while others require that previous fix packs are applied as a prerequisite. Each supported DB2 operating system has its own fix pack numbering scheme, and its own schedule for creating fix packs.
There is an Internet site where you can download DB2 fix packs and find out more about the fix packs that are available. Fix packs are stored in separate directories for each locale (national language).
The Internet site also provides lists of fixes that you can browse to see if there is a fix for a problem you encountered.
To access this site, either:
When you have downloaded a fix pack, please ensure that you fully review the associated README file before applying the fix pack. The README file contains any special instructions regarding the fix pack. Release Notes also accompany each fix pack, and may contain corrected documentation as well as supplemental information about DB2 Universal Database and other vendor products.
Note that the README file may instruct you to rebind the applications and utilities on your DB2 server and clients. For information on binding, see the Quick Beginnings for the appropriate operating system.
Before you use the fix pack on all of your production systems, use the fix pack on your test environment to ensure that it installs correctly. This should be done . On the rare occurrence when a fix pack may not install correctly, it is easier to recover from a problem with your test environment than with your production systems.
