We have set up the ASM (Automatic Storage Management), a new feature of Oracle 10g, on Linux server. In this article, I would like to share the installation and configurations steps what I have followed.
System Details:
Operating System: Linux – Red Hat Enterprise Linux 4.0
Kernel Version: 2.6.9-42.ELsmp
Architecture: 32 bit x86
Database: Oracle 10g
Version: Release 2 (10.2.0.1)
Following are the steps I have followed.
1) Download the ASMLib software packages from the Oracle Technology Network, below is an URL for the same.
http://www.oracle.com/technology/software/tech/linux/asmlib/rhel4.html
oracleasm-support-2.0.3-1.i386.rpm
oracleasmlib-2.0.2-1.i386.rpm
oracleasm-2.6.9-42.ELsmp-2.0.3-1.i686.rpm
Note: Download as per your OS Kernel and Architecture
# uname -r
2.6.9-42.ELsmp
# uname -i
i386
3) Upload the above 3 packages using ftp in Linux server, and log on to the server as root , and install them as below.
$ su – root
Password:
Go to the rpms directory where rpms are downloaded.
# rpm –Uvh oracleasm-support-2.0.3-1.i386.rpm \
oracleasmlib-2.0.2-1.i386.rpm \
oracleasm-2.6.9-42.ELsmp-2.0.3-1.i686.rpm

2:oracleasm-2.6.9-42.ELsm############################# [ 67%]
3:oracleasmlib######################################## [100%]
ASMLib software packages are now installed successfully.
4) Run the following command to configure ASMLib, outputs of the commands are the self explanatory.
To Configure
# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library driver. The following questions will determine whether the driver is loaded on boot and what permissions it will have. The current values will be shown in brackets ('[]'). Hitting
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Fix permissions of Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: [ OK ]
Creating /dev/oracleasm mount point: [ OK ]
Loading module "oracleasm": [ OK ]
Mounting ASMlib driver filesystem: [ OK ]
Scanning system for ASM disks: [ OK ]
To Start and Stop ASM
# /etc/init.d/oracleasm disable
Writing Oracle ASM library driver configuration: [ OK ]
Unmounting ASMlib driver filesystem: [ OK ]
Unloading module "oracleasm": [ OK ]
# /etc/init.d/oracleasm enable
Writing Oracle ASM library driver configuration: [ OK ]
Loading module "oracleasm": [ OK ]
Mounting ASMlib driver filesystem: [ OK ]
Scanning system for ASM disks: [ OK ]
5) Making Disks Available to ASMLib
To create a Disk Group
# /etc/init.d/oracleasm createdisk VOL1 /dev/sda2
Marking disk "/dev/sda2" as an ASM disk: [ OK ]
To Delete a Disk Group
# /etc/init.d/oracleasm deletedisk VOL1
Deleting Oracle ASM disk "VOL1" [ OK ]
To query the disks
# /etc/init.d/oracleasm querydisk /dev/sda2
Disk "/dev/sda2" is marked an ASM disk with the label "VOL1"
# /etc/init.d/oracleasm querydisk /dev/sda1
Disk "/dev/sda1" is not marked an ASM disk
To list and query the existing disks
# /etc/init.d/oracleasm listdisks
VOL1
# /etc/init.d/oracleasm querydisk VOL1
Disk "VOL1" is a valid ASM disk on device [8, 2]
We are now done with installation and configuration of ASMLib on Linux platform.
Conclusion: This article is specific to one of our Linux boxes, I would request you to refer other documents in Oracle or Google for respective Operating Systems i.e. Windows and Unix.
