Oracle 11.2 Now does not allow you to deinstall software via the OUI interface directory . Any Requests for software deinstallation using the OUI will tell you to use the deinstall utility
There is a new utility know as deinstall available in $ORACLE_HOME/deinstall that allows for deinstallation
$ORACLE_HOME/deinstall/deinstall will allow for deinstallation in the form shown below
The deinstall process will cleanly deinstall the software and detach the Oracle Home.
