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″

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 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.

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

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

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

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

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.

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.

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.

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

Hi Atul,
how come I can only create a single ASM instance vs clustered ASM instance when creating the database?

Thank you.

Hi Atul,
I’ve change the display name and i’ve check the user equivalence also, everything it is showing passed accept the virtual-ip node connectivity.

ERROR: could not find a suitable set of interfaces for VIP’s
Result : Node connectivity checked failed

I thought the VIP interface should not work until *after* the cluster installed and VIPCA ran.

still i’ve got the same error you must enter the unique values for all the nodes in the cluster,the name rac2 that you entered is being used by more than once for the same node

I’ve check all ssh combination also it is working fine .
I’m using RHEL AS4 operating system
can u plz. let me know how to solve the problem

thanks
Majid

Still I’ve got the same issue after changing the /etc/hosts file by putting three IP’s

Hi Majid I’m getting the same error as you are did you manage to fix the error?

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.

Hi Atul,

Still I’m facing the same problem after changing the /etc/hosts file.

Majid

Atul,

I have followed line by line and word by word of your doc, i still face the same issue of ” unique values for public node name, priv node name, virtual host name for all nodes in the cluster”.
Please do let me know how to resolve this issue.

Thanks,
Sathya

any update?

Chucks

check following as suggested to majid

Open vmx (Vmware configuration file for second node i.e. RAC2) “Red Hat Enterprise Linux 3.vmx” and change DisplaName to RAC2

This is mentioned in my doc as

######

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

#######

Hi Atul,
i successfully configured RAC with ASM based on your step by step approach.
the suggestions i am giving is
1)For vip issues in /etc/hosts make separate ip for vip –
127.0.0.1 loalhost.localdomain localhost
# Public
192.168.1.101 rac1.majid.com rac1 rac1-vip.majid.com rac1-vip
192.168.1.102 rac2.majid.com rac2 rac2-vip.majid.com rac2-vip

#Private
192.168.0.101 rac1-priv.majid,com rac1-priv
192.168.0.102 rac2-priv.majid.com rac2-priv
#vip
192.168.0.201 rac1-vip.majid,com rac1-vip
192.168.0.202 rac2-vip.majid,com rac2-vip
During running of root.sh at rac2 i got error (i resolved with m/l doc 356535.1
2)regarding ssh without passwords i changed home direcory permissions 700 (by default )with useradd and chmod .Instead of oracle group, i created oinstall(primary) and dba groups only with useradd.
3)regarding ownership and permissions on raw devices
i used chown -R root:dba /dev/raw/raw1 &raw2 (ocr+vd)(chmod 660) and chown -R oracle:dba /dev/raw/raw3 with 660 permissions
4)During installation of RHEL i went manual partition and created separate directory /apps (15g)
– I checked off several compat* rpm’s and later i installed by taking rhel as3 RPM’S (cd 2/3)which are in sync with cluvfy
5)the success of cluvfy is much depends on JDK installation. I installed jdk1.4 in /usr/local/java and made reflection in /etc/profile(export java_home/path). the same i reflected in oracle .bash_profile (PATH)
If you follow these changes,atul’s approach may lands you towards success.
thanks,

Hi Atul,
Im trying to install RAC based on your documents. While Specify Cluster Configurtion ie. adding second node rac2, im facing error “You must enter unique value for public node name,the private node name and the virtual host name for all nodes in the cluster.The name rac1 you entered is being used more than once for the same node.”
My /etc/host is like

# Private

After running the command “./runcluvfy.sh stage -pre dbinst -n rac1,rac2 -r 10gR2 -verbose” i got the following output.

As per you old comments for the same error i changed the vmx file of RAC2 to displayName=”rac2″

Can u pls let me know how can slove this issue

regards

jibin

Hi Atul,
Thanks for immediate reply
I made changes in the hosts file as u said. But still i am getting the same error.
In the second node the hostname is rac2 only, when i am giving hostname -a its showing “rac2-vip rac2-vip”.
can u pls advice me to solve this error.

regards,
jibin

I am getting the same error inpsite of making changes..

The name rac1 you entered is being used more than once for the same node.

Atul Please help

Will I be correct to say the following error which everyone is getting i.e “The name rac1 you entered is being used more than once for the same node” will not arise if I create a virtual machine for RAC2 from stratch instead of clonning it for RAC1.

I am about to get to that stage and I just want to know if this can be a workaround for the above error.

Thanks
