I am installing 11.2.0.2 database. I have to upgrade my OPatch to apply the latest patch. When I download the p688088_112000.zip. I unzipped it under the $ORACLE_HOME. When I check to see if my OPatch version has been upgraded, it hasn't. I tried several times but can't figure out why it is not upgrading. Anybody have any idea what is wrong? Any help would be appreciated.
