The following are some of the new ASM related features introduced in 11g R2:
[oracle@redhat346 stage]$ sqlplus sys/xxx as sysdba SQL*Plus: Release 11.2.0.1.0 Production on Fri Oct 16 09:10:55 2009 Copyright (c) 1982, 2009, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Automatic Storage Management option SQL> shutdown immediate; ORA-01031: insufficient privileges
The example below will show how we can configure and mount a ACFS on Red HatLinux with 11g R2.
Note: ASM operations like creating and adding disk groups etc which were earlier performed via DBCA will now be performed via the GUI ASM Configuration Assistant which needs to be launched via the ‘asmca‘ command from the Grid Infrastructure Home.
We first create a disk group called ASMCFS and then create a volume called ASMCFS_VOL1 of 25 GB using the disk group that we just created.
We will then use a mount point /u03 to mount this file system. A configuration script is created which includes the commands to be run as root to mount this file system. After the script is run we will see the ACFS file system mounted on /u03.
/bin/mount -t acfs /dev/asm/asmcfs_vol1-44 /u03 chown oracle:dba /u03 chmod 775 /u03 [oracle@redhat346 stage]$ df -k Filesystem 1K-blocks Used Available Use% Mounted on ..... ...... /dev/asm/asmcfs_vol1-44 26214400 89112 26125288 1% /u03

Hi ,
I need clearification before i can start installing of 11g grid infrastructure can i need to install GRID_HOME and ORACLE_HOME binary all other node separately or it’ll install automatically . As i know from some other doc that these HOME we can’t install on ACFS or cluster file system then how can we share across all nodes .
Thanks in advance .

Hi Santosh – if you have say two nodes in the cluster, you need to only do the installation once – when you configure SSH (which is one of the initial RAC setup steps), it will enable the installation user account to remotely login to the other nodes in the cluster and perform the software installation – not very clear what you question regarding ACFS is – can you please clarify – thanks
Gavin,
Thansks for such a nice article! I am planning to go with ACFS and my question to you is what are the prerequisits which I may need to deal with SA team. If I get storage, how do I deal with to make it ACFS copatible, if you remeber there used to steps to configure OCFS2 in 10g, if we have to do same then couold you please provide all those details.
Thanks
Narendra
