Last updated on OCTOBER 07, 2010

Oracle Server - Enterprise Edition - Version: to - Release: 10.2 to 11.1
Information in this document applies to any platform.


The Clusterware patches for 10g and 11g contain binaries that can be installed in the Clusterware home (CRS_HOME), and the database home (RDBMS_HOME). Due to normal upgrading of the Oracle software in a RAC environment, customers may want to maintain multiple Oracle homes of different versions. Under some situation, customers may need to apply a CRS patch to either CRS_HOME or RDBMS_HOME.

The README.txt that comes with a CRS patch generally assumes customers apply the patch to both CRS_HOME and RDBMS_HOME at the same time. This note gives instructions on what to do if customers need to apply a CRS patch to only CRS_HOME or only RDBMS_HOME.

Customers may need to do this when:

1). Customers have a mixed CRS and RDBMS version. Details of this scenario can be found in note: 363254.1
2). Customers need to apply a CRS patch to a single ASM instance environment, or single instance Exadata ennvironment. For example, patch ocssd.bin on single ASM instance environment; patch diskmon.bin on a single instance Exadata environment.

Disclaimer: This note only gives a general guidance on what to do if customers applies the CRS patch to only CRS_HOME or RDBMS_HOME, it does not intend to replace README.txt that comes with the CRS patch. Customers should always read README.txt thoroughly and follow the applicable steps carefully in the README.txt.
