Error description
If a v9.5 DB2 product is installed first then the v9.5 merge modules are subsequently installed. the DB2 product copy will be the default copy. When you try to uninstall that DB2 product, the installer asks user to switch the default copy first. This is correct if there is other non-merge module db2 copy installed on the system. Otherwise, as in the scenario described above, it is not correct because the v9.5 DB2 merge module copy can not be set as the default db2 copy on the system. In other words. it is the design that you can not switch the default copy to the v9.5 DB2 merge module copy.
Local fix
If there is no other db2 copy installed on the system, except the v9.5 db2 merge module copy, you can use the following command to demote the default copy before uninstalling it: db2lswtch.exe -demote
