Add second node rac2 by clicking on Add link,after adding second step i am geting below error.
The name rac1 you entered is being used more than once for the same node.
can u pls let me know how can solve this problem.

On which step of this doc you are facing this issue ?

Did you follow all steps from previous post specially this one

--Now on vmx file of RAC2 “Red Hat Enterprise Linux 3.vmx” change following lines from displayName = "RAC1" to displayName = "RAC2"

Oracle RAC Part IV : Install Oracle Clusterware and Cluster Database.

step : Add second node rac2 by clicking on Add link

i am facing my problem here.

OK so when you add second node you have to select RAC2 node or second machine and not rac1 as RAC1 is already there

while adding second node i am getting this error.

while specifying OCR location i am geeting below error.
----------------------------------
the location /apps/oracle/oradata/ocr enteted FOR ocr is not shared across all the nodes in cluster specify shared raw
partion oracle cluster file system that visible by the same on all nodes on the cluster.

i have solved my previous problem

can i pls get help on this.

You again missed some of step from previous part.

Make sure you can view ocr filesystem/directory from both nodes.

check again that you followed all steps documented.

Hi Atul,
How do I download the files mentioned and copy them over to my vm????
My internet does not work from my vm (I have a wireless connection)...

Thanks in advance
Chris

Chris download them to your laptop and burn cd. CD drive should be accessible from virtual machine

Hi Atul, can u suggest some possible scenarios to test the RAC

Hi Atul,

Atlast my dream comes true by installing RAC, becos of UR great articles in this post.

Can u plz suggest on this,

Customer has a 3 node 10.1 RAC cluster database on RHEL3.0. They want to move to RHEL4.2 with 10.2. Since 4.2 is a brand new install, I am trying to find out whether they need additional servers to do this upgrade OR can they do this:
Delete a node from their 3 node RAC and go down to 2 nodes. Yes, the application can run fine with 2 nodes! Build this deleted node as a 1 node RAC with RHEL4.0 and 10.2 from scratch. Set up this new node as a physical standby for the 2 node RAC primary. Then delete the 2nd node from the primary and build it from scratch with RHEL4.2 and Oracle 10.2 and add to the single node standby to make it into 2 node standby. Then do a FAILOVER from the 1 node primary to 2 node standby. Make this 2 node standby as the new primary. Rebuild the old 1 node primary with RHEL4.0 and Oracle 10.2 and add it to this new 2 node primary to make it a 3 node primary.
This will take a lot of time, but this will provide us with little downtime. So as you can see the Data Guard is not used for DR purpose. It is used for upgrade purpose. If this is possible, then we don't want to ask the customer to invest in additional servers for the upgrade.
Can this be done or am I dreaming?

Yasser.

Yaseer,
RH 3 can be upgraded to 4 and there is no need to do fresh install of RH4 . Do let me know why you want to do fresh install

Hi Atul,

In our company our Linux admin team have planned to do a fresh install of RH 4 becos of some internal issues present in OS(Due to implement of wrong methods in applying OS patches) hence we(DBA) are facing lot of DB performance issues.....

Can you plz suggest that the above solution mentioned in my last post is possible or not!!!!!!
If possible is there any other way to achieve this target with less downtime....

Regards,
Yasser.

Atul,

Thanks for such an excellent step by step instruction about RAC.

Cluster ware Installation successful on node 1 and when I ran root.sh on node2 , I am getting below error message and CRS is not started on node

Any Hint

Failure at final check of Oracle CRS stack.
10

Note:I used Redhat linux es version 3.0 update 9 and the rpm’s mentioned by you were not installed

rpm –ivh compat-glibc-7.x-2.2.4.32.6.i386.rpm
rpm –ivh gnome-libs-1.4.1.2.90-34.2.i386.rpm
rpm –ivh sysstat-4.0.7-4.EL3.3.i386.rpm

Is there any relation to this error and non installed rpm’s

Try this with all RPM's in place and any other required prereqs.

Did anybody get Oracle 10g RAC installed successfully using this detailed guide? I am having raw file permission issues and I found a fix on 2-day RAC on oracle website.

Hi Anonymous User,
I posted this after configuring RAC on my laptop twice so I think this all works but I would really like to hear what issue you got any how you fixed it to understand in what different way you used this guide . This will help me in improving this document

My Linux version:
[oracle@rac1 ~]$ uname -r
2.6.9-42.0.0.0.1.EL

Database Version:
Oracle 10g 10.2.0.1.0

Same instructions to different people can lead to different results. my root.sh stopped somewhere when installing clusterware. and i found out that /dev/raw/raw? permission has been changed from oracle:oinstall to root:oinstall. So I went to oracle office website for instruction and they said a file /etc/udev/permissions.d/oracle.permission needs to be created.

[oracle@rac1 ~]$ cat /etc/udev/permissions.d/oracle.permissions
chmod 666 /dev/raw/raw1
chown root:oinstall /dev/raw/raw2

chmod 666 /dev/raw/raw2
chmod 666 /dev/raw/raw3
chown oracle:oinstall /dev/raw/raw[23]

But for some reason, it still doesn't work so put the scripts to /etc/rc.d/rc.local and I re-install clusterware it is successful (of course I removed some files left by previous installation).

When running root.sh during clusterware installation on rac2, I need to manually run vipca in X to setup the vip interface.

Then I got the online staus when running 'crs_stat -t'. Yeah!!!

Thanks Atul, you really did a good jobs guiding a novice like me to advanced RAC.

Hi Anonymous , first of all congrats for successful RAC installation on your PC/Machine/Laptop. Thanks for sharing this information and yes are true, Same instructions to different people can lead to different results (If even small things is skipped, changed, missed or errored out).

Thanks once again for sharing this

To clarify, I was using Enterprise Linux 4 Update 4 downloaded from Oracle Official website. But your guide is using Redhat Linux ES3. Probably that is the reason. Thanks.

Hi Atul,

I really appricated your efforts.I am facing a problem when i am insatting clusterware in rhel4 linux.After running the root.sh on both noods

OUI-25031: Some of the configuration assistants failed. It is strongly
recommended that you retry the configuration assistants at this time. Not
successfully running any "Recommended" assistants means your
system will not be correctly configured.

1. Check the Details panel on the Configuration Assistants Screen to see
the errors resulting in the failures.
2. Fix the errors causing these failures.
3. Select the failed assistants and click the 'Retry' button to retry them.

Please suggest..

I'm trying to install the a 2 oracle RAC node. the architecture of my Oracle Rac is two database servers and shared disk array.
I've successfully installed the clusterware, ASM and RAC on DBServer1. When i installed the clusterware on DBServer2, installation overwrite OCR and Voting Disk files which is located on the shared disk. So do i have to reinstall the oracle clusterware on DBServer1? when i run "olsnode" on DBServer1, it show only one node. When i run "olsnode" on DBServer2, "PRCO-4: OCR initialization failed, PROC-33: Oracle Cluster Registry is not configured Operating System error [No such file or directory] [2]"

Can anyone have idea what's wrong with it? I've been searching the solutions for several days but i can't.

Thanks in advance,
Ray

Hi Atul,
I'm having problems running oui at the configure ASM stage. oui can't see any member disk. This is after entering /dev/raw/raw3.

The install is on Oracle Enterprise Linux R4

Any pointers please?

Hi Atul,

While specifying the cluster configuration, I am facing below error:

You must enter unique values for public node name, the private node name and the virtual hostname for all nodes in the cluster. The name, RAC1, that you entered is being used by more than once for the same node.

I have changed Display name ='RAC2' for second node.

Could you please look into it.

Hi Atul,

Could you please let me know, from where can I download Enterprise Linux RPMs?

Thanks.

Hi Atul,

Thanks for this article.

many of us facing the same issue as mentioned below.
In Step iv

While specifying the cluster configuration, I am facing below error:

I seen the image 3 in part four & entered exactly the same value but still I am facing the issue.

Thank,
