Upgrading Opatch from 10.2.0.4.2 to 10.2.0.5.1 Version

Upgrading Opatch to Latest Version :

It is so simple to upgrade th Opatch version for your database.

I will check my current version of Opatch
[oracle@linux5 OPatch]$ opatch version
Invoking OPatch 10.2.0.4.2

OPatch Version: 10.2.0.4.2

OPatch succeeded.

Now download the latest Opatch version from oracle support site.
in this case I have downloaded p6880880_101000 & moved it to the database server
Move the patch file to your oracle home

[oracle@linux5 OPatch] mv p6880880_101000_SOLARIS64.zip $ORACLE_HOME
[oracle@linux5 OPatch] cd $ORACLE_HOME
(If a former OPatch directory already exist, then rename it)

Make sure you backup your current Opatch home
                                                                     
[oracle@linux5 OPatch] mv Opatch OPatch_100057_OLD    

Now unzip the patch file
[oracle@linux5 OPatch] unzip p6880880_101000_SOLARIS64.zip
