Oracle 26ai- Installing Oracle Grid Infrastructure for a Standalone Server Using the Command-Line Interface

Before Oracle AI Database 26ai, Oracle Grid Infrastructure could be installed using a response file.

For example(using a response file):

./gridSetup.sh -silent \
INVENTORY_LOCATION=/oraInventory \
SELECTED_LANGUAGES=en \
ORACLE_BASE=/grid/base \
oracle.install.option=HA_CONFIG \
oracle.install.asm.OSDBA=asmdba \
oracle.install.asm.OSOPER=asmoper \
oracle.install.asm.OSASM=asmadmin \
oracle.install.crs.config.autoConfigureClusterNodeVIP=false \
oracle.install.asm.diskGroup.name=ASM \
oracle.install.asm.diskGroup.redundancy=EXTERNAL \
oracle.install.asm.diskGroup.diskDiscoveryString='ORCL:*' \
oracle.install.asm.diskGroup.disks=ORCL\:ASM01 \
oracle.install.asm.SYSASMPassword=Your_Password \
oracle.install.asm.monitorPassword=Your_Password \
-ignorePrereqFailure

At the end of the installation, the installer displays a message similar to the following:

As install user, execute the following command to complete the configuration.
        /grid/19.25/gridSetup.sh -executeConfigTools -responseFile /grid/19.25/install/response/grid_2025-03-28_08-34-17AM.rsp [-silent]

Therefore, we should use a response file such as the following:

[grid@OL95 ~]$ cat /grid/19.25/install/response/gridsetup.rsp
oracle.install.responseFileVersion=/oracle/install/rspfmt_crsinstall_response_schema_v19.0.0
INVENTORY_LOCATION=/oraInventory
oracle.install.option=HA_CONFIG
ORACLE_BASE=/grid/base
oracle.install.asm.OSOPER=asmoper
oracle.install.asm.OSASM=asmadmin
oracle.install.asm.OSDBA=asmdba
oracle.install.asm.SYSASMPassword=Deraz_Kolah_122_Kebria
oracle.install.asm.diskGroup.name=ASM
oracle.install.asm.diskGroup.redundancy=EXTERNAL
oracle.install.asm.diskGroup.disks=ORCL:ASM01
oracle.install.asm.diskGroup.diskDiscoveryString=ORCL:*
oracle.install.asm.monitorPassword=Deraz_Kolah_122_Kebria

Starting with Oracle AI Database 26ai, Oracle Grid Infrastructure can be installed and configured using the command-line interface. Oracle provides the -configureCluster and -configureStandaloneServer options for the gridSetup.sh command. The -configureCluster option is used to configure Oracle Grid Infrastructure for a cluster, while the -configureStandaloneServer option is used to configure Oracle Grid Infrastructure for a standalone server.
In this article, I will show how to install and configure Oracle Grid Infrastructure on a standalone server using the -configureStandaloneServer option.
As the grid user, run the following command:

[grid@OL95 26ai]$ ./gridSetup.sh  -silent -configureStandaloneServer \
  -OSDBA asmdba \
  -OSASM asmadmin \
  -OSOPER asmoper \
  -ORACLE_BASE /grid/base \
  -dbDiskGroupName ASM \
  -diskList 'ORCL:ASM' \
  -redundancy EXTERNAL \
  -diskString 'ORCL:*'  \
  -executeRootScript \
  -configMethod root \
  -auSize 64 \
  -INVENTORY_LOCATION /oraInventory

The command completes the Oracle Grid Infrastructure configuration and creates and starts the ASM instance. After the configuration completes successfully, we can verify the ASM instance by connecting to it using SQL*Plus as SYSASM:

[grid@OL95 ~]$ sqlplus "/as sysasm"

We can also use ASMCMD to verify that the ASM disk group was created and mounted successfully:
