Installing CRS

The CRS software is installed on each node in the location created in Preparing $CRS_HOME and $ORACLE_HOME on each node.

 To install CRS

1. Make sure that the Oracle installer is in a directory that is writable. If you are using the CD-ROM, make sure that the Oracle installation files are copied locally.

   By default, the installsfrac utility uses ssh for remote communication. However, rsh can be used in place of ssh by using the "-rsh" option with the installsfrac utility.

2. On the same node where you have set the environment variables, execute the following command as root:

   # cd /opt/VRTS/install

   # ./installsfrac -configure

   The installer will display the copyright message.

3. When the installer prompts, enter the system names separated by spaces on which to configure Storage Foundation for Oracle RAC. For the installation example used in this procedure:

   galaxy nebula

   The installer checks both systems for communication and creates a log directory on the second system in /var/tmp/installsfracxxxxxxxxxx, where xxxx represents the timestamp.

4. When the initial system check is successfully completed, press Enter to continue.
5. The installer proceeds to verify the license keys. When the licenses are successfully verified, press Enter to continue.
6. Following the instructions presented, navigate to the Main Menu and select Install or relink Oracle. Some choices choices for installing and configuring may vary, depending on the operating system you are running.
7. In the Choose Oracle version menu, select the appropriate version of Oracle (10gR1 or 10gR2).
8. In the Choose task menu, select the task Install Oracle Clusterware (CRS).
9. In the Set DISPLAY dialog, enter the value for DISPLAY. The value of DISPLAY variable should be <ip-address-of-the-machine>: 0 .
10. Enter Oracle user and group information.
    • In the Oracle Username dialog, enter Oracle Unix User Account when prompted. The installer checks for the user on all systems.
    • In the Oracle Groupname dialog, enter Oracle Inventory group when prompted. The installer checks for group existence on all systems.
    • Press Enter to continue.
11. In the CRS Install Image dialog, enter the absolute path of CRS install image when prompted. The installer validates the CRS installer. Press Enter to continue.
12. In the Oracle base directory dialog, enter the location of base of the Oracle directory structure for OFA compliant databases. The installer validates the Oracle Base Directory. If the directory doesn't exist , installer prompts for the creation of oracle base directory on all nodes. Choose option 'y' to create oracle base directory on all nodes.
13. Press Enter to continue.
14. In the CRS Home directory dialog, enter absolute path of CRS home directory when prompted. Installer validates the CRS home directory. If the directory doesn't exist , installer prompts for the creation of the directory on all nodes. Choose option 'y' to create oracle base directory on all nodes.
15. Press Enter to continue.
16. The Installer prints the CRS installation information for verification. If the information displayed by the installer is correct choose option "y" otherwise choose option "n".

    Example:

    Oracle environment information verification

    Oracle Unix User: oracle

    Oracle Unix Group: oinstall

    Oracle Clusterware (CRS) Installation Path: /orcl/10gR2/CRS/Disk1

    Oracle Clusterware (CRS) Home: /app/oracle/crshome

    Oracle Release: 10.2

    Oracle Base: /app/oracle

    Is this information correct? [y,n,q] (y)

17. Press Enter to continue.

    The Storage Foundation installer invokes the Oracle Universal Installer (OUI) for Oracle CRS Installer.

18. Consult Oracle documentation to provide the required information and install Oracle CRS using the Oracle interface.
19. If you are installing Oracle 10gR1 as a base install, when you reach the Summary dialog box, click Install. When the installation ends, a Setup Privileges message appears. Do not click OK at this point; instead, apply the init.cssd.patch patch on each node:
    • Log in as root user.
    • Navigate to $CRS_HOME/css/admin.
    • Run the following command:

      # patch init.cssd. < /opt/VRTSvcs/rac/patch/init.cssd.patch

20. In the Summary dialog box, click Install. When the installation ends, a Setup Privileges message appears. Do not click OK; instead, first run the root.sh script on each node. For example:

    # cd $ORACLE_HOME

    # ./root.sh

21. Click OK on the Setup Privileges message.
