Installing the CRS

Use the Oracle10g RAC runInstaller utility to install the CRS component before installing Oracle 10g binaries and the database. The software is installed on each node in the location created in Preparing $CRS_HOME and $ORACLE_HOME on each node. Complete the procedure below and refer to the Oracle Real Application Clusters Installation and Configuration Guide for additional information:

 To install the CRS

1. Log in as Oracle user and launch the Oracle 10g runInstaller utility on the first node. With the Oracle10g CRS disc in the CD-ROM drive, enter:

   $ cd /cdrom/cdrom0

   $ ./runInstaller

   • When runInstaller prompts you to run the script /oracle/oraInventory/orainstRoot.sh, make sure the script exists on each node before proceeding. If so, skip to step n.
   • If the /oracle/oraInventory/orainstRoot.sh script does not exist on each node, copy it from the first node to each of the other cluster nodes.
   • Run the /oracle/oraInventory/orainstRoot.sh script on each node.
2. As you run the installer, prepare the following information required for the installation and configuration of the CRS component:
   • The installation destination, $CRS_HOME, on each node (for example, /oracrs/), and the path to $CRS_HOME for the Specify File Locations dialog box.
   • The names of the nodes and their associated host names for the Cluster Configuration dialog box.
   • The private NIC IP addresses for each node (for example, qfe1 on subnet 192.168.0.0) for the Private Interconnect Enforcement dialog box. Make sure the correct interface type exists for the interface name.
   • The name of a file in the OCR directory or raw volume for the Oracle Cluster Registry dialog box.

     Example: /oravote/ocr

   • The name of a file in the VOTE-disk directory or raw volume for the Voting Disk dialog box.

     Example: /oravote/vote

3. When runInstaller prompts you to run the script, run root.sh on each node:

   # cd $CRS_HOME

   # ./root.sh

   This starts the CRS daemons on the node where you enter the command.

4. Click OK on the Setup Privileges message and exit the wizard.

   The VIP Configuration Assistant appears. This wizard prompts you for the virtual IP address you configured.
