I am in the process of migrating from cloudscape to db2 for Websphere Portal Server 220.127.116.11.
One of the pre-requisite is to have db2 v9.1 client installed without FP4 on the same box where websphere portal is installed.
I currently have db2 v9.1 FP4 client installed & want to remove the FP4 keeping the sanity of db2 v9.1.
For Linux® and UNIX® operating systems, you can go back to an earlier fix pack level by reinstalling an earlier fix pack. On Windows® operating systems, you cannot remove a fix pack once it has been installed.
To uninstall a fix pack on Linux or UNIX operating systems, use the installFixPack command with the force option (-f) to bypass the level check. For example, to uninstall DB2® Version 9.1 Fix Pack 2, run the installFixPack command from within the DB2 Version 9.1 Fix Pack 1 installation image as follows:
./installFixPack -f -b DB2DIRwhere DB2DIR is the location of the DB2 database products that you want to force to a lower level fix pack image.
