Thanks,
Merri

Hi,

### find package installed 

 rpm -qa |grep oracleasm

### Remove package

rpm -e <package_name>

Hi,
Check if SELinux is disable or in permissive mode.

If SELinux is enable(enforcing) you must disable SELinux or put it in permissive mode.

Use this tool
# system-config-securitylevel

or manually:

1) Go to modify /etc/selinux/config in redhat. It looks like this:

# SELINUX= can take one of these three values:
# enforcing – SELinux security policy is enforced.
# permissive – SELinux prints warnings instead of enforcing.
# disabled – SELinux is fully disabled.
SELINUX=enforcing —> change it to SELINUX=disabled
2) Reboot server to take it effect

Thanks alot levi for prompt reply,will you please give some useful link to download asm guide and good articles,kindly share your experience i am new in asm technology

Tell me one more thing i install oracleasm-2.6.9-55.EL-2.0.3-1.i686.rpm but i had to install this oracleasm-2.6.9-55.ELsmp-2.0.3-1.i686.rpm this rpm i found in rhel-4 becauze i am working on 2.6.9-55.ELsmp i686 kernel which use ELsmp
am i right?

Thanks & Regards,
Merri

Hi,
You can use this notes on MOS:
*FAQ ASMLIB CONFIGURE,VERIFY, TROUBLESHOOT [ID 359266.1]*

*Tips On Installing and Using ASMLib on Linux [ID 394953.1]*

Or OTN:
http://www.oracle.com/technetwork/topics/linux/asmlib/index-101839.html

> The package oracleasm must be installed according version and type of Kernel.

You can install all packages (kernel types) from an Kernel Version (i.e 2.6.9-55.*).


e.g

Kernel : 2.6.9-55 ( EL)
You must install and use oracleasm-2.6.9-55.EL-2.0.3-1.i686.rpm

Kernel : 2.6.9-55 ( ELsmp)
You must install and use oracleasm-2.6.9-55.ELsmp-2.0.3-1.i686.rpm

You can have both packages installed, but each package will use only your kernel current.


See this example in my envorimment.

$ rpm -qa |grep oracleasm-2.6
oracleasm-2.6.18-194.el5debug-2.0.5-1.el5
oracleasm-2.6.18-194.el5xen-2.0.5-1.el5
oracleasm-2.6.18-194.el5-2.0.5-1.el5
oracleasm-2.6.18-194.el5PAE-2.0.5-1.el5

### I have installed 4 package to 4 different types of kernel.

## My current kernel is :

uname -r
2.6.18-194.el5

So the package configured and in use : oracleasm-2.6.18-194.el5-2.0.5-1.el5

Hello,
i have installed linux redhat 4.5/4.7 and i manually set the partition in the starting of Linux installation for e.g
/ 30gb
/boot 4gb
/tmp 4gb
/oracle 15gb

when i installation required rpm oracleasmlib,oracleasm-support and kernel.asm convert above partition to it's own partition....is this right?

Thanks,
Merri

Hi Merri,
No, its complete wrong.

You need the concept of ASM.

I recommend you: Introduction to Automatic Storage Management (ASM)
http://download.oracle.com/docs/cd/B28359_01/server.111/b31107/asmcon.htm

Here an good article about how configure ASMLib and ASM
ASM using ASMLib and Raw Devices
http://www.oracle-base.com/articles/10g/ASMUsingASMLibAndRawDevices.php

You don't need format device (partition) just create a partition with fdisk like /dev/sdb1 and mark this partition as ASMDISK

e.g
/etc/init.d/oracleasm createdisk VOL1 /dev/sdb1
After that you install Oracle Software and Configure ASM.

Levi Pereira

Thank alot levi for brief description,All asm package configure with help of you.

will you please guide me how to create partition through fdisk i want to create 4 partition/disk.please explain in brief i want to learn but unable to create fdisk partition i tried it but it corrupt my vm machine partition and machine got hang.

Hi,

Please follow this guide STEP-BY-STEP.

http://www.oracle-base.com/articles/11g/OracleDB11gR2RACInstallationOnOEL5UsingVMwareServer2.php

You don't need format device (partition) just create a partition with fdisk like /dev/sdb1 and mark this partition as ASMDISK

e.g
/etc/init.d/oracleasm createdisk VOL1 /dev/sdb1
After that you install Oracle Software and Configure ASM.

How can i create i tried but failed.firstly i have to create primary then select second /dev/sdb2 then create primary then /dev/sdb3,so what is role of extended partition and logical shud i create extended and logical also?

Thanks,
Merri

Hi,

Let's use the disk sdb but without using extended partition.
I suppose wich the disk sdb is only for tests and is avaliable only to Oracle ASM.

cd /dev
# ls sd*
sda  sda1  sda2  sdb  

So, lets create primary partition on disk sdb

fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.


The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Then just mark the Partition sdb1 as ASMDISK.
