Oracle Database Oracle Clusterware Installation Guide for HP-UX

Installing Oracle Clusterware with OUI
❏ Identify shared storage for Oracle Clusterware files and prepare disk partitions
if necessary
During installation, you are asked to provide paths for two files that must be
shared across all nodes of the cluster, either on a shared raw device, or a shared
file system file:
– The voting disk is a partition that Oracle Clusterware uses to verify cluster
node membership and status.
The voting disk must be owned by the user performing the installation
(oracle or crs), and must have permissions set to 640.
– The Oracle Cluster Registry (OCR) contains cluster and database configuration
information for the Oracle RAC database and for Oracle Clusterware,
including the node list, and other information about cluster configuration and
profiles.
The OCR disk must be owned by the user performing the installation (crs or
oracle. That installation user must have oinstall as its primary group.
The OCR disk partitions must have permissions set to 640, though
permissions files used with system restarts should have ownership set to
root:oinstall. During installation, OUI changes ownership of the OCR
disk partitions to root. Provide at least 280 MB disk space for the OCR
partitions.
If your disks do not have external storage redundancy, then Oracle recommends
that you provide one additional location for the OCR disk, and two additional
locations for the voting disk, for a total of five partitions (two for OCR, and three
for voting disks). Creating redundant storage locations protects the OCR and
voting disk in the event of a disk failure on the partitions you choose for the OCR
and the voting disk.

6.3 Installing Oracle Clusterware with OUI
This section provides you with information about how to use Oracle Universal
Installer (OUI) to install Oracle Clusterware. It contains the following sections:
■ Running OUI to Install Oracle Clusterware
■ Installing Oracle Clusterware Using a Cluster Configuration File
■ Troubleshooting OUI Error Messages for Oracle Clusterware
6.3.1 Running OUI to Install Oracle Clusterware
Complete the following steps to install Oracle Clusterware on your cluster. At any
time during installation, if you have a question about what you are being asked to do,
click the Help button on the OUI page.
1. Unless you have the same terminal window open that you used to set up SSH,
enter the following commands:
$ exec /usr/bin/ssh-agent $SHELL
$ /usr/bin/ssh-add
2. Start the runInstaller command from the /Disk1 directory on the Oracle
Database 11g release 1 (11.1) installation media.
