I want to update my OPatch version from 126.96.36.199.1 to 188.8.131.52.3 on My LINUX server, to do so we need to apply patch 6880880
$ cd $ORACLE_HOME/OPatch
crs docs emdpatch.pl fmw jlib ocm opatch opatch.ini opatch.pl opatchprereqs
Download patch 6880880 from Oracle support and Copy the p6880880_112000_Linux-x86-64.zip file to $ORACLE_HOME location.
Before unzip the file backup the existing OPatch folder
$mv OPatch OPatch.bak
Now, unzip the file then you’ll see new OPatch folder.
$ unzip p6880880_112000_Linux-x86-64.zip
New OPatch version is created.
$ cd /opt/oracle/app/184.108.40.206/OPatch
