Installing a Local GIMR for a New Cluster

Complete this procedure to install a local Grid Infrastructure Management Repository (GIMR) for Oracle Standalone Cluster and Oracle Domain Services Cluster.

If you want to place GIMR on an Oracle ASM disk group, then create an Oracle ASM disk group for GIMR either during Oracle Grid Infrastructure installation or using Oracle ASMCA before installing the GIMR.

1. Ensure that you can access other nodes with SSH. The installer requires that the grid user is permitted to set up passwordless SSH. The installer can set this up for you automatically, or your system administrator can set this up for you before installation is started.
2. As the grid user, create GIMR home directory on all cluster nodes:

   $ mkdir -p /u01/app/21.0.0/gimr
   $ chown grid:oinstall /u01/app/21.0.0/gimr

3. Download the Oracle Database image files and extract the files into the GIMR home. For example:

   $ cd /u01/app/21.0.0/gimr
   $ unzip -q download_location/db_home.zip

   db_home.zip is the name of the Oracle Database image zip file.

   Note:

   • You must extract the zip image software into the directory where you want your GIMR home to be located.

   • Download and copy the Oracle Database image files to the local node only. During installation, the software is copied and installed on all other nodes in the cluster.

4. From the GIMR home directory, start the Oracle Database software installation:

   $ cd /u01/app/21.0.0/gimr
   $ ./runInstaller

   Note:

   Run the runInstaller command from the GIMR home directory only. Do not run runInstaller command that resides at $GIMR_HOME/oui/bin/, or any other location, to install Oracle Real Application Clusters.
5. In the Select Configuration Option screen, select the Setup Software Only option. Click Next.
6. In the Select Database Installation Option screen, select the Oracle Real Application Clusters Database Installation option. Click Next.
7. In the Node Selection screen, select all the nodes to install Oracle RAC or Oracle RAC One Node software. Click Next.
8. In the Select Database Edition screen, select the Enterprise Edition option. Click Next.
9. In the Specify Install Location screen, provide the location of Oracle base for Oracle RAC software installation.
   The Oracle base directory must be different from the GIMR home directory. Click Next.
10. In the Privileged Operating System Groups screen, accept the default operating system group names for Oracle Database administration and click Next.
11. Select the option to Automatically run configuration scripts. Enter the credentials for the root user or a sudo account, then click Next.
    Alternatively, you can run the scripts manually as the root user at the end of the installation process when prompted by the installer.
12. The Perform Prerequisite Checks screen displays the results of the prerequisites checks. If any of the checks have a status of Failed and are not Fixable, then you must manually correct these issues. After you have fixed the issue, you can click the Check Again button to have the installer recheck the requirement and update the status. Repeat as needed until all the checks have a status of Succeeded. Click Next.
13. Review the contents of the Summary screen and then click Install.
    The installer displays a progress indicator enabling you to monitor the installation process.
14. If you did not configure automation of the root scripts, then you are required to run root.sh script as the root user, as specified in the Execute Configuration Scripts window. Do not click OK until you have run the root.sh script on all nodes as directed.
    You can run the root.sh script simultaneously on all nodes in the cluster for Oracle RAC installations or upgrades.
15. Create GIMR container database using the following command:

    $ /u01/app/21.0.0/gimr/bin/mgmtca createGIMRContainer [-storageDiskLocation disk_location]
