B How to Perform Oracle Clusterware Rolling
Upgrades
This appendix describes how to perform Oracle Clusterware rolling upgrades. Because
you must stop database processes on the nodes you intend to upgrade when you
perform an Oracle Clusterware upgrade, it includes information about how to stop
processes in Oracle Real Application Clusters (Oracle RAC) databases.
The instructions in this section specify a single node, and assume that you are
upgrading one node at a time. To upgrade a subset of nodes together, you can specify
a list of nodes (the subset), where the example commands specify a single node. For
example, instead of -n node, specify -n node1,node2,node3.
This appendix contains the following topics:
Note: You can use the procedures in this chapter to perform rolling
upgrades of Oracle Clusterware from any Oracle Clusterware 10g or
Oracle Clusterware 11g installation to the latest patchset update. For
example, you can use these procedures to prepare to upgrade from
Oracle Clusterware 10.2.0.1 to 10.2.0.3.

B.1 Back Up the Oracle Software Before Upgrades
Before you make any changes to the Oracle software, whether you intend to upgrade
or patch part of the database or clusterware, or all of your cluster installation, Oracle
recommends that you create a backup of the Oracle software.
B.2 Restrictions for Clusterware Upgrades to Oracle Clusterware 11g
To upgrade existing Oracle Clusterware and Cluster Ready Services installations to
Oracle Clusterware 11g, you must first upgrade the existing installations to a
minimum patch level. The minimum patch level is listed in the following table:
