Oracle Database Oracle Clusterware Installation Guide for HP-UX

Preparing to Install Oracle Clusterware with OUI
❏ Prepare for Clusterware Upgrade If You Have Existing Oracle Cluster Ready
Services Software
During an Oracle Clusterware installation, if OUI detects an existing Oracle
Database 10g release 1 (10.1) Cluster Ready Services (CRS), then you are given the
option to perform a rolling upgrade by installing Oracle Database 11g release 1
(11.1) Oracle Clusterware on a subset of cluster member nodes.
If you intend to perform a rolling upgrade, then you should shut down the CRS
stack on the nodes you intend to upgrade, and unlock the Oracle Clusterware
home using the script mountpoint/clusterware/upgrade/preupdate.sh,
which is available on the 11g release 1 (11.1) installation media.
If you intend to perform a standard upgrade, then shut down the CRS stack on all
nodes, and unlock the Oracle Clusterware home using the script
mountpoint/clusterware/upgrade/preupdate.sh.
When you run OUI and select the option to install Oracle Clusterware on a subset
of nodes, OUI installs Oracle Database 11g release 1 (11.1) Oracle Clusterware
software into the existing Oracle Clusterware home on the local and remote node
subset. When you run the root script, it starts the Oracle Clusterware 11g release 1
(11.1) stack on the subset cluster nodes, but lists it as an inactive version.
When all member nodes of the cluster are running Oracle Clusterware 11g release
1 (11.1), then the new clusterware becomes the active version.
If you intend to install 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.
❏ Determine the Oracle Inventory location
If you have already installed Oracle software on your system, then OUI detects the
existing Oracle Inventory directory from the /var/opt/oracle/oraInst.loc
file, and uses this location.
If you are installing Oracle software for the first time on your system, and your
system does not have an Oracle inventory, then you are asked to provide a path
for the Oracle inventory, and you are also asked the name of the Oracle Inventory
group (typically, oinstall).
See Also: The preinstallation chapters in Chapter 2 for
information about creating the Oracle Inventory, and completing
required system configuration
❏ Obtain root account access
During installation, you are asked to run configuration scripts as the root user. You
must run these scripts as root, or be prepared to have your system administrator
run them for you. Note that these scripts must be run in sequence. If you attempt
to run scripts simultaneously, then the installation will fail.
❏ Decide if you want to install other languages
During installation, you are asked if you want translation of user interface text into
languages other than the default, which is English.
Note: If the language set for the operating system is not supported
by Oracle Universal Installer, then Oracle Universal Installer, by
default, runs in the English language.
