Installing CRS

If you chose Install Oracle Clusterware (CRS) in the SF Oracle RAC configuration program, then after you set the Oracle 10g environment variables, the program launches the Oracle utility to install CRS.

Make sure any required HP-UX patches listed in the Oracle documentation are installed before you install the CRS software. You must install CRS in the $CRS_HOME location on each node that you created.

See Preparing $CRS_HOME on each node

Note When the Oracle 10g CRS installation prompts you to run the root.sh script, make sure to patch the init.cssd script before running root.sh.

To install CRS

Make sure you set the environment variables using the configuration program.
See Setting Oracle environment variables and invoking the Oracle installer
When the Oracle installer prompts you to run the /oracle/oraInventory/orainstRoot.sh script, make sure the script exists on each node before proceeding.
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.

As you run the installer, be prepared with the following information required for the installation and configuration of the CRS component:

Specify File Locations dialog box

The installation destination ($CRS_HOME) on each node.
For example, /oracrs.

The path to $CRS_HOME.

Cluster Configuration dialog box

The names of the nodes and their associated host names.

In the example CRS installation, the nodes and their associated host names are galaxy and nebula.

Private Interconnect Enforcement dialog box

The private NIC IP addresses you have set up for each node.

For example, lan1 on subnet 1.0.0.0.

Oracle Cluster Registry dialog box

The name of a file in the OCR directory or raw volume.

For example, a file named ocr_file in the directory /ocrvote/ocr.

Voting Disk dialog box

The name of a file in the Vote-disk directory or raw volume.

For example, a file named vote_file in the directory /ocrvote/vote.

When you arrive at the Install screen, click Install.
Follow the wizard instructions to install CRS.
In the Setup Privileges Notice dialog box, click OK.
The installer prompts you to run the root.sh script.

Before you run the root.sh script, you need to add the init.cssd.patch.

Open another window on the system where you are running the installer.
Log in as superuser.

Change to the directory where the patch is to be copied:

Oracle 10g R1

# cd $CRS_HOME/css/admin

# cp /opt/VRTSvcs/rac/patch\

/init.cssd-10gR1.patch .

Oracle 10g R2

# cd $CRS_HOME/css/admin

# cp /opt/VRTSvcs/rac/patch\

/init.cssd-10gR2.patch .

Run the following command to install the patch:
# patch < init.cssd.patch init.cssd
Run the root.sh script. For example:
# cd $CRS_HOME

# ./root.sh

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

Repeat step 9 on each cluster node.
