Hello,
Is it an extract from MySQl or Oracle? Describe in greater detail what is the problem and what do you want to achieve. Make sure that you meet the prerequsites.
Regards,
Nice post I was checking constantly this blog and I’m impressed! Very useful info specifically the last part I care for such info a lot I was looking for this certain information for a long time Thank you and good luck
I am curious about your 11.2.0.1 –> 11.2.0.3 RAC upgrade on Linux. You did not mention where you got ASMlib .. as far as I can tell, there is no ASMLib for OEL 61 .. which means your guide is bogus in the part where you show you are marking ASM disks .. you typed that part versus showing us a screen shot .. please explain .. BTW, I am impressed with the overall quality of the guide except for this glaring error. Please advise.
Hi,
I am using OEL 6.0 and 6.1 for some my articles and ASMlib DOES come with the media in OEL 6.0 and OEL 6.1. So I reuse the old ASMlib knowledge that are still valid and applicable for OEL 6.X.
There is ASMlib for OEL 6.X, look for the rpm that install it.
Regards,
Hi,
There is nothing bogus. See for yourself.

Hi,
Thanks for your rapid reply. Everything in your response makes perfect sense. However, where did you get the kernel-specific portion of the 3 components of ASMlib. When I issue
root@oel61a Packages]# /usr/sbin/oracleasm scandisks
Reloading disk partitions: done
Cleaning any stale ASM disks…
Scanning system for ASM disks…
[root@oel61a Packages]# /usr/sbin/oracleasm createdisk DISK1 /dev/sdb1
Writing disk header: done
Instantiating disk: failed
Clearing disk header: done
This is due to my not having the kernel-specific part ..I am running the same version of OEL61 as your guide .. in fact, I have been very successful in the execution of your clearly written steps; however, I cannot continue until I can stamp the 5 disks as ASM .. what am I missing?
Thanks for your help.

Hi,
ASMlib is there it is a permission issue due to the SELINUX. I remember disabling SELINUX. Set the SELINUX=disabled and reboot the servers.
vi /etc/sysconfig/selinux
SELINUX=disabled
Regards,
You got the missing part 🙂 I now have 5 ASM disks .. I might suggest that you put that step in your guide about disabling SELINUX .. I look forward to continue the setup with your excellent guide. Thanks for your continued assistance. BTW, are you from Sofia? I have a co-worker who is from Sofia 🙂
Hi,
Which article are you referring to that needs an update? Usually SELINUX is disabled for all my RAC installations as Oracle RAC used to be incompatible with SELINUX. Specify the URL so that I change it accordingly.
Small world huh? No I am not.
Regards,
I am working with ‘Build two node Oracle RAC 11gR2 11.2.0.3 with GNS .. the default install of OEL61 has SELINUX enforced by default. If you mention to disable it during the OS install, then there will not be an issue with creating the ASM disks .. it was from October 05 2011. BTW again, I only mentioned Sofia as your install screen in this guide showed Sofia as the time zone .. no big deal 🙂
Hi,
Thank you for pointing it out.
Added a Revision 1.0 : 19th April 2012 : DISABLE SELINUX in order to successfully create ASM disks using ASMlib

Hi,
Love your website. Will you be posting example of VM Server 3x and Oracle VM Manager 3x installation either in Virtual Box or on actual Linux?
Hi,
Good idea.I will take some spare time to really test it and post the documented steps for installation.
Regards,
Hi,
Seems that you cannot run Oracle VM Server 3.0.X under VirtualBox, although you can install it. Oracle VM Server 3.0.3 relies on dmidecode for some hardware detection capabilities and this is not exposed to VirtualBox guests. Thus, discovery from VM Manager fails. VM Server 3.1.1 is supposed to drop the dmidecode requirement (Not released yet).

Dear all,
Does any body try to install oracle 10.2.0.1 64 bit RAC clusterware in OLE5 Update 8 using vmware workstation 9 and then update to it to 10.2.0.5 clusterware.
I had installed 10.2.0.1 clusterware successfully. When I upgraded it to 10.2.0.5, the both nodes kept rebound suddenly.
Does any body know why?

Hi,
Thanks for posting the detailed steps for RAC to RAC Data Guard setup. It is very nice article. In your DG setup you temporarily set cluster_database=FALSE during the clone with RMAN, I am wondering what is the benefit of this or because there was issue with duplicate from RAC to RAC.
Best
