The purpose of this document is to give a description of Oracle Interim Patch Installer (OPatch) and how to use it with Oracle Application Server 10g Release 2 (10.1.2), Release 3 (10.1.3) , and Identity Management 10g (10.1.4).


Updating OPatch to the latest release is a REQUIREMENT for all one-off patches, including the Critical Patch Updates. Without the latest release, the patching may fail due to new functionality introduced.

First, there is a patch required which upgrades the Oracle Universal Installer (OUI <Patch 6640838>). Apply this according to the readme and/or <Note 565374.1>. This updates the OUI Installer files from to and allows certain functions such as applying newer overlay merge patches. (Where you will get an error, "OPATCH_JAVA_ERROR=CheckConflict: OPatch cannot process overlay patches" without Note this updates OPatch to but the next step instructs to apply the latest OPatch to avoid some other known issues with newer one-off packages.

When patching Oracle Application Server 10g where the OPatch utility is required, only OPatch should be downloaded. It will actually be a version, as <Patch:6880880> is used to obtain the latest OPatch utility available. The readme states the actual version which will be downloaded. It should be simply extracted into the Oracle home over the original directory to provide a version - which is required version.

The following is the method to see what version you have installed:
ORACLE_HOME/OPatch/opatch version
