Install Oracle RAC or Oracle RAC One Node software using the gold
image-based installation with Oracle AI Database setup wizard.
Oracle Real Application Clusters Database installation is a two-step process.
This procedure describes the first step — to install Oracle RAC
software.
If you have an existing Oracle installation, then write down the version
numbers, patches, and other configuration information, and review upgrade
procedures for your existing installation. Review Oracle AI Database Upgrade
Guide before proceeding with the installation.
Ensure that you have su or sudo credentials, because you will be required to either provide root credentials to automatically run the root scripts or run a script as the root user during installation.
- Ensure that you can access other nodes with SSH. The installer requires that the user account running the Oracle RAC installation 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.
- Open the terminal from which you intend to run the installer,
and log in as the user account that you want to own the
Oracle AI Database installation (for example,
oracle).
If you are not able to turn off
stty commands, or have other
restrictions that prevent automatic SSH
configuration from within the installer, then you
must ensure that SSH is configured and enabled
before you proceed to start installation.
- Download the Oracle AI Database installation image files
(
db_home.zip) and extract the files
into a new Oracle home directory. For example:
$ mkdir -p /u01/app/oracle/product/23.0.0/dbhome_1
$ chgrp oinstall /u01/app/oracle/product/23.0.0/dbhome_1
$ cd /u01/app/oracle/product/23.0.0/dbhome_1
$ unzip -q /tmp/db_home.zip
Note:
-
Oracle recommends that the Oracle
home directory path you create is in compliance
with the Oracle Optimal Flexible Architecture
recommendations. Also, unzip the installation
image files only in this Oracle home directory
that you created.
-
Oracle home or Oracle base cannot
be symlinks, nor can any of their
parent directories, all the way to up to the
root directory.
- From the Oracle home directory, start the Oracle AI Database
software installation:
$ cd /u01/app/oracle/product/23.0.0/dbhome_1
$ ./runInstaller
Note:
Run
the
runInstaller command from the
Oracle home directory only. Do not
run
runInstaller command that
resides at
$ORACLE_HOME/oui/bin/,
or any other location, to install Oracle Real
Application Clusters or Oracle Grid
Infrastructure.
- In the Select Configuration Option screen, select the Setup Software Only option. Click Next.
- In the Select Database Installation Option screen, select the Oracle Real Application Clusters Database Installation option. Click Next.
- In the Node Selection screen, select all the nodes where you want to install Oracle RAC or Oracle RAC One Node software. Click Next.
- In the Select Database Edition screen, select the Enterprise Edition option. Click Next.
- 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 Grid home directory. Click Next.
- In the Privileged Operating System Groups screen, accept the
default operating system group names for Oracle AI Database
administration and click Next.
- 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.
- 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.
- Review the contents of the Summary screen and then click Install.
The installer displays a progress indicator enabling you to monitor the installation process.
- 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.
After installing Oracle RAC software, run Database Configuration Assistant (DBCA) from the ORACLE_HOME/bin/dbca directory to create and configure Oracle RAC databases.
