Installing Oracle Grid Infrastructure for a Standalone Server

Complete these steps to install Oracle Grid Infrastructure for a standalone server and then create a database that is managed by Oracle Restart.

Note:

Oracle ASM Filter Driver (ASMFD) is desupported on both Linux and Oracle Solaris beginning with Oracle Database 23ai.

On Linux systems running kernel 5.14 or higher (including Oracle Linux, RedHat Enterprise Linux, and SUSE Linux Enterprise Server), ASMFD filtering was disabled and is unsupported. Oracle recommends moving to ASMlib v3 for those environments, as it provides equivalent functionality. For details, see My Oracle Support Document 2806979.1. Migration steps are available for Oracle Restart and Oracle Grid Infrastructure. On Oracle Solaris, ASMFD is now desupported.

Install Oracle Grid Infrastructure for a standalone server, which installs Oracle Restart and Oracle ASM, and creates one disk group.

You should have your network information, storage information, and operating system users and groups available to you before you start the installation. You should also be prepared to run root scripts or provide information to automate root scripts.

Log in as the Oracle Restart software owner user (oracle).
If this is the first time you are installing Oracle software, then create the Oracle base and the Oracle inventory directories as per the Oracle Optimal Flexible Architecture (OFA) recommendations. Specify the correct owner, group, and permissions for these directories.
```
# mkdir -p /u01/app/oracle
# mkdir -p /u01/app/oraInventory
# chown -R oracle:oinstall /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oraInventory
# chmod -R 775 /u01/app
```
Download the Oracle Grid Infrastructure for a standalone server installation image files, create the grid home directory, and extract the image files in this grid home directory.
For example:
```
$ mkdir -p /u01/app/oracle/product/23.0.0/grid
$ cd /u01/app/oracle/product/23.0.0/grid
$ unzip -q /tmp/grid_home.zip
```
Note:
- Ensure that the Grid home directory path you create is in compliance with the Oracle Optimal Flexible Architecture recommendations. Also, unzip the installation image files only in this Grid 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.
Log in as the Oracle Restart software owner user and run gridSetup.sh to start the Oracle Grid Infrastructure setup wizard:
```
$ Grid_home/gridSetup.sh
```
Where Grid_home is the Oracle Grid Infrastructure home directory.
Note:
You can use the gridSetup.sh command with the -applyRU and -applyOneOffs options to install Release Updates (RUs) and one-off patches during an Oracle Grid Infrastructure installation or upgrade.
In the Select Configuration Option screen, select the Configure Oracle Grid Infrastructure for a Standalone Server (Oracle Restart) option to install and configure Oracle Restart and Oracle ASM. Click Next.
During installation, disk paths mounted on Oracle ASM and registered on Oracle ASMLib with the string ORCL:* are listed as default database storage candidate disks.
On Linux, if you are using NVMe over Fabrics storage devices, then use the n:/*/* disk discovery string.
Configure Oracle ASM as needed with additional disk groups.
- The default Disk Group Name is DATA. You can enter a new name for the disk group, or use the default name.
- Any additional disk devices that you create must be owned by the user performing the grid installation.
Respond to the configuration prompts as needed to configure Oracle Grid Infrastructure. Click Help for information.
Provide information to automate root scripts, or run scripts as root when prompted by OUI.

If you configure automation for running root scripts, and a root script fails, then you can fix the problem manually, and click Retry to run the root script again.
Start the Oracle Database installation, and select Oracle ASM disk groups for Oracle Database files storage. For assistance during installation, click Help on the Oracle Universal Installer page where you need more information.
