Installing an Upgrade On a Subset of Nodes
B-6 Oracle Clusterware Installation Guide
Checking to see if Oracle CRS stack is down...
Oracle CRS stack is down now.
7. Confirm that you are logged in as the Oracle Clusterware installation owner, and
start Oracle Universal Installer to install the software.
For example:
$ whoami
crs
$ cd /cdrom/clusterware/
./runInstaller
Provide information as prompted by the Installer.
Note: You cannot change the owner of the Oracle Clusterware home.
8. During an Oracle Clusterware installation, if Oracle Universal Installer detects an
existing Oracle Clusterware 10g release 1 or release 2 installation, then you are
given the option to perform a rolling upgrade by installing Oracle Clusterware 11g
release 1 on a subset of cluster member nodes.
By default, all the cluster member nodes are checked for upgrade. To perform a
rolling upgrade of a subset of nodes, uncheck the cluster member nodes you do
not want to upgrade on the Specify Hardware Cluster Installation Mode
installation screen.
9. After you select the nodes you want to upgrade, the Installer installs the Oracle
Clusterware 11g release 1 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 release or patchset. The
script starts the Oracle Clusterware 11g release 1 stack on the upgraded subset of
nodes. However, it lists it as an inactive version.
10. After you upgrade the initial node or subset of nodes, repeat steps 1 through 10 for
each remaining node or subset of nodes until all nodes in the cluster have been
upgraded 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.
11. Check with Oracle Support, and apply any recommended patch sets, bundle
patches or critical patches.
