create an Oracle ASM cluster file system using the Oracle ASM Configuration Assistant (ASMCA)

Create Mount Point

From each Oracle RAC node, create a directory with root user that will be used to mount the new Oracle ACFS:

[oracle@MUMCHORA38 ~]$ su - root

[root@MUMCHORA38 ~]# mkdir /GG

[oracle@MUMCHORA39 ~]$ su root

[root@MUMCHORA39 ~]# mkdir /GG

Create ASM Cluster File System

As the Oracle Grid Infrastructure owner, run the ASM Configuration Assistant (asmca) from only one node in the cluster (MUMCHORA38 1st node for example):

When the Oracle ASM configuration assistant starts you are presented with the 'Disk Groups' tab.

Click on the 'Volumes' tab then click the [Create] button.

Create a new ASM volume by supplying a "Volume Name", "Disk Group Name", and "Size".

I will be creating a 99GB volume named " ACFSGG_VOL1" on the "GG" ASM disk group.

After verifying all values in this dialog are correct, click the [OK] button.

After the volume is created, acknowledge the 'Volume: Creation' dialog.

When returned to the "Volumes" tab, the "State" for the new ASM volume should be ENABLED for

all Oracle RAC nodes (i.e. 'ENABLED(2 of 2)').

Click on the 'ASM Cluster File Systems' tab then click the [Create] button.

Verify that the newly created volume (ACFSGG_VOL1) is selected in the 'Volume' list.

Select the 'General Purpose File System' option.

Select the 'Yes' option for 'Register MountPoint'.

After verifying all values in this dialog are correct, click the [OK] button.

Enter the previously created mount point directory (/GG) or leave the suggested mount point as in

above screen shot.

After the ASM Cluster File System is created, acknowledge the 'ASM Cluster File System:

Creation' dialog.

The newly created Oracle ASM cluster file system is now listed under the 'ASM Cluster File

Systems' tab.

Note: the new clustered file system is mounted. That no need to be performed manually on all Oracle RAC nodes after exiting from the ASMCA.

Exit the ASM Configuration Assistant by clicking the [Exit] button.

Verify Mounted Cluster File System on all node

To verify that the new cluster file system mounted properly, run the following mount command

from all Oracle RAC nodes:

Set Permissions

With the new cluster file system now mounted on all Oracle RAC nodes, change the permissions

to allow user access. I want to grant the oracle user account and oinstall group read/write

permissions. Run the following as root from only one node in the Oracle RAC:

Test

Now let's perform a test .

Create one directory on 1st node and check is it visible on both node.
