Review this information to configure Oracle ACFS for an Oracle RAC Oracle Database home.
Oracle ACFS is installed as part of an Oracle Grid Infrastructure installation 12c release 2 (12.2).
You can also create a General Purpose File System configuration of ACFS using ASMCA.
To configure Oracle ACFS for an Oracle Database home for an Oracle RAC database:
Install Oracle Grid Infrastructure for a cluster.
Change directory to the Oracle Grid Infrastructure home. For example:
$ cd /u01/app/12.2.0/grid
Ensure that the Oracle Grid Infrastructure installation owner has read and write permissions on the storage mountpoint you want to use. For example, if you want to use the mountpoint
$ ls -l /u02/acfsmounts
Start Oracle ASM Configuration Assistant as the grid installation owner. For example:
The Configure ASM: ASM Disk Groups page shows you the Oracle ASM disk group you created during installation. Click the ASM Cluster File Systems tab.
On the ASM Cluster File Systems page, right-click the Data disk, then select Create ACFS for Database Use.
In the Create ACFS for Database window, enter the following information:
Volume Name: Enter the name of the database home. The name must be unique in your enterprise. For example:
Mount Point: Enter the directory path for the mount point. For example:
Make a note of this mount point for future reference.
Size (GB): Enter in gigabytes the size you want the database home to be. The default is 12 GB and the minimum recommended size.
Owner Name: Enter the name of the Oracle Database installation owner you plan to use to install the database. For example:
Owner Group: Enter the OSDBA group whose members you plan to provide when you install the database. Members of this group are given operating system authentication for the SYSDBA privileges on the database. For example:
Select Automatically run configuration commands to run ASMCA configuration commands automatically. To use this option, you must provide the root credentials on the ASMCA Settings page.
Click OK when you have completed your entries.
If you did not select to run configuration commands automatically, then run the script generated by Oracle ASM Configuration Assistant as a privileged user (
root). On an Oracle Clusterware environment, the script registers the ACFS as a resource managed by Oracle Clusterware. Registering ACFS as a resource helps Oracle Clusterware to mount ACFS automatically in proper order when ACFS is used for an Oracle RAC Oracle Database home.
During Oracle RAC installation, ensure that you or the DBA who installs Oracle RAC selects for the Oracle home the mount point you provided in the Mount Point field (in the preceding example,
