How to Verify that the ACFS Driver is installed and loaded

How to Verify that the ACFS Driver is installed and loaded - Oracle Server - Enterprise Edition - Version: 11.2.0.2 and later [Release: 11.2 and later ]

This node describes how you can verify that

1.) your platform supports ACFS

2.) the ACFS driver is installed

3.) the ACFS driver loaded

Solution

There is a tool called acfsdriverstate in the folder $GRID_HOME/bin , that can be used.

usage: acfsdriverstate [-orahome <ORACLE_HOME>] <installed | loaded | version | supported> [-s]

First we would like to know if your OS platform supports ACFS. We use the option supported and find:

acfsdriverstate -orahome /home/oracle/app/oracle/product/11.2.0/grid supported

ACFS-9200: Supported

that means our platform is supported. In case it is not supported we get

acfsdriverstate -orahome $ORACLE_HOME supported

ACFS-9459: ADVM/ACFS is not supported on this OS version: '2.6.32-100.26.2.el5'

ACFS-9201: Not Supported

To check if the driver is installed, we can use

acfsdriverstate -orahome /home/oracle/app/oracle/product/11.2.0/grid installed

ACFS-9203: true

The result true shows here that it is installed.

To see if the Driver is loaded into the kernel we can use the following command:

acfsdriverstate -orahome /home/oracle/app/oracle/product/11.2.0/grid loaded

ACFS-9203: true
