SEVERE:OUI-67073: Apply Session failed: ApplySession::processLocal() failed in system

Problem Description
OPatch apply Patch failed with the following error.
SEVERE:OUI-67073: Apply Session failed: ApplySession::processLocal() failed in system, inventory

From the OPatch logfile I get the following entries,

INFO:Finish backing up system for rollback at Thu Apr 01 12:12:13 EST 2010
INFO:Start the Apply preScript at Thu Apr 01 12:12:13 EST 2010
SEVERE:OUI-67021:SEVERE:OUI-67073: Apply Session failed: ApplySession::processLocal() failed in system, Return Code = 1
INFO:Finish the Apply preScript at Thu Apr 01 12:12:13 EST 2010
INFO:Execution of PRE script failed, with return value = 1

Cause of the Problem
The problem occurred due to oracle bug 6880880. This bug fire if the OPatch version in the $ORACLE_HOME isn't up to date.

Solution of the Problem
Look at the post http://arjudba.blogspot.com/2010/03/severe-oui-67073-applysession-failed.html where the similar error is described.

To solve above bug you have to use the latest released OPatch 10.2, which is available for download from My Oracle Support patch 6880880 by selecting the 10.2.0.0.0 release. After you download that OPatch, install it and then try to apply the patch set again.
