Oracle Database Oracle Clusterware Installation Guide for HP-UX

Installing an Upgrade On a Subset of Nodes
B-4 Oracle Clusterware Installation Guide
You can patch the entire cluster, and then run the root.sh patch script in a rolling
fashion to make the patch update active.
4. After you select the nodes you want to upgrade, the Installer installs the patch
software in the existing Oracle Clusterware home on the local and the remote
subset of nodes you have selected.
OUI prompts you to run the appropriate root script for the patchset. The script
starts the Oracle Clusterware stack on the upgraded subset of nodes. However, it
lists it as an inactive version.
5. After you upgrade the initial node or subset of nodes, repeat steps 1 through 4 for
each remaining node or subset of nodes until all nodes in the cluster have been
patched, and the new version is the active version.
When all member nodes of the cluster are running the new Oracle Clusterware
release, then the new clusterware becomes the active version. Otherwise, the older
Oracle Clusterware release is still used.
To list the version of Oracle Clusterware that is installed on a node, enter the
following command, where CRShome is the Oracle Clusterware home, and
nodename is the name of the node:
# CRShome/bin/crsctl query crs softwareversion [nodename]
To list the Oracle Clusterware software version that is running on a node, enter the
following command, where CRShome is the Oracle Clusterware home:
# CRShome/bin/crsctl query crs activeversion
If you intend to install or upgrade Oracle RAC, then you must first complete the
upgrade to Oracle Clusterware 11g release 1 (11.1) on all cluster member nodes
before you install the Oracle Database 11g release 1 (11.1) version of Oracle RAC.
6. Check with Oracle Support to confirm you have installed any recommended patch
sets, bundle patches or critical patches.
To check for the latest recommended patches for Oracle Clusterware and Oracle
Real Application Clusters, log on to the following site:

Patches list. Provide information as prompted.
B.5 Installing an Upgrade On a Subset of Nodes
To upgrade an Oracle Clusterware release, you must shut down all Oracle Database
instances on the subset of nodes you want to upgrade before modifying the Oracle
software. Review the instructions in the release upgrade README document for
additional instructions specific to the upgrade.
Before you shut down any processes that are monitored by Enterprise Manager Grid
Control, set a blackout in Grid Control for the processes that you intend to shut down.
This is necessary so that the availability records for these processes indicate that the
shutdown was planned downtime, rather than an unplanned system outage.
To shut down Oracle processes and upgrade a subset of nodes, complete the following
steps:
