Tim,

Why not use Oracle VM? It's free, faster and supported by Oracle...

hi i tried to follow all the instructions but at certain point i took a snapshop of RAC1 using vmware, not knowing that is will using the 10g space of the RAC1 /dev/sda. I have installed the CRS software but when i tried to install Oracle Db software it gave me a warning that available disk space is 2gb only required 3.5gb. so i shut it down and added another disk to RAC1 using vmwre add hardware utility and than restarted RAC1 and mounted the new disk to /etc/fstab. Now when i run the ./runInstaller it dosent give me the "Cluster Install option" instead it goes straight to the pre-requisite checks screen. What can i do to get it to do the Clusterd db installation.

thanks

a great 'how to'. After each backup, I found it necessary to run the following:

exec /usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add

before running any oracle installs.

Also, I have had problems with the listener crashing every 5-10 minutes.

Will try oracle VM.

I have done that toutorial , it is working , thanks, 2 questions

1-i can't issue conn system/passwprd@rac2
2- what is the next step i should do to master RAC

Hi.

1) It means either your listener.ora or tnsnames.ora configuration is incorrect. Make sure they are correct.

2) Read the manuals and practice every scenario they discuss. Many performance tuning issues are hard to simulate on on a test system. You need a significant load to cause performance issues associated with RAC. Consider using SwingBench or some other load tool.

Note. Questions in forum please, not in comments. :)

Cheers

Hi

There is little change for the RAC2 .bash_profile
Old Entries
ORACLE_SID=RAC2; export ORACLE_SID
ORACLE_HOSTNAME=rac1.localdomain; export ORACLE_HOSTNAME

New Entries
ORACLE_SID=RAC2; export ORACLE_SID
ORACLE_HOSTNAME=rac2.localdomain; export ORACLE_HOSTNAME

ORACLE_HOSTNAME needs to be changed to rac2.localdomation in the RAC2's oracle user's .bash_profile

thanks

hi tim, i am having issue while installing oracle 11g, i have completed Install the Clusterware Software without any issue but unable to complete create the asm instance part. the rac2 node keep on crashing . i use 1792 meg memory for each node ( kept some for host system).
please help
syed

Hi.

For 11gR2 I am easily able to do the installation with only 1G of RAM on each VM. Remember, the host OS is doing a lot of work, so don;t try and run it with less than 1G.

If the CPU is underpowered, the clusterware can freak if the VMs stay at 100% too long, so this could be the problem. Also, if the times of the two machines vary,this will cause clusterware to freak.

When clusterware freaks it will often cause one of the nodes to reboot.

Cheers

thank you Tim I finished this.

There small problem u didnt mention is that when install db instance there is two error
ora-15032
ora-15063

I solution is here
http://forums.oracle.com/forums/thread.jspa?threadID=600837&start=15&tstart=0
modify /u01/app/oracle/admin/+ASM/pfile/init.ora

specify all the disk is ASM_DISKSTRING without *.

just in case someone meet the same problem.

Thank you again.

Tim... said...

Hi.

I didn;t mention it because I don't get that error. Done this installation many times and never seen it.

Cheers

Hi

I tried installing the CRS Software. Up to installation it went well, running the root.sh script is failing. Successfully run the root.sh on first node(RAC1). When I tried to run the root.sh on second node(RAC2) its rebooting. Not able to proceed further. Don't know why!

If some one can spare time for me, that will be a gr8 help.

Thanks
Bhupesh

Hi.

Failures are typically because:

1) You've not used the same software and versions as me.
2) Your shared disks are not configured correctly.
3) Your servers do not have the same system time.
4) Your networking is not set up properly.
5) You've not followed all the prerequisite steps.
6) You are trying to perform the installation without enough memory on the host OS.

I've been doing these installations for years with no problem. Every time someone fails it invariably comes down to one of these issues.

Cheers

Hi Tim,
Thank you. I have downloaded Nero to copy Oracle software to a CDrom then read from VM. Everything works fine now. Thank you very much for all the instructions to make VMware/Linux/RAC work together.
you are the best.
Robin

Oh Tim, my email is as following:

Thank for your help.

I think Oracle-base did great job on all Oracle RAC and 11g installation on Linux. However, I wish this instruction for 11g RAC/Linux could be more specific on the cluster installation. I downloaded clusterware, but never see any ./runInstaller from the download. nowhere to find the executable to start cluster installation.
Please help!
Thanks,
robin

Tim... said...

Hi.

Just like every other bit of Oracle database software you've ever installed, when you unzip the software you are left with a directory. When you CD into that directory there is a runInstaller script. If it is not there then you have a faulty download.

Cheers
