DB2 Version 9.7 for Linux, UNIX, and Windows

Uninstalling fix packs

After installing a fix pack, you can revert to a previous fix pack or the GA level of the DB2® product.

Before you begin

On Linux and UNIX operating systems, you can go back to an earlier fix pack or the GA level.

On Windows operating systems, you cannot go back to a previous fix pack or the GA level unless you uninstall the current fix pack, then install the previous level.

Procedure

On Linux or UNIX operating systems, to uninstall a fix pack, use the installFixPack command with the force option (-f) to bypass the level check. The command must be run from the lower level fix pack or GA image. For example:
```
./installFixPack -f level -b DB2DIR
```
where
- DB2DIR is the location of the DB2 product that you want to force to a lower level fix pack or GA image. For example:
```
./installFixPack -f level -b /opt/ibm/db2/V9.7
```
On Windows operating system, to uninstall a fix pack, use the Add/Remove Programs window, accessible through the Windows Control Panel. Refer to your operating system's help for more information about removing software products from your Windows operating system.
Associate the instance with another DB2 copy that is at a lower level than the original DB2 copy where the instance was running. You can update all instances by issuing db2iupdt -D from the new directory.

What to do next

Note: Before you uninstall the current fix pack, you remove or uninstall any functionality that does not apply to the earlier fix pack or the GA level. For example, before you revert to DB2 Version 9.7 GA level, you must do the following:

Drop any work action sets that were associated with a workload.
Drop any UOWTOTALTIME thresholds.
