1. Randomly at least one, sometimes both of my vmware instances would hang. At the time of the hang I could see that they were both accessing shared disk, specifically the voting and ocr disks.
In my vmware.log file I could see the following error:
Msg_Post: Error Mar 12 16:47:25: vmx| [msg.log.error.unrecoverable] VMware Server unrecoverable error: (vmx) Mar 12 16:47:25: vmx| NOT_IMPLEMENTED
I searched in vain for a solution and finally sent an email to the Oracle-L list. Thankfully Edgar saw my post and provided me with the solution. If your running on a slow computer (I didn't think my brand spanking new laptop was slow ;) you could have locking issues. In each of your vmware configuration files put the following line:
2. You should read the following notes before you start and modify your steps accordingly:
Subject: 10gR2 RAC Install issues on Oracle EL5 or RHEL5 or SLES10 (VIPCA Failures) Doc ID: Note:414163.1
Subject: VIPCA FAILS COMPLAINING THAT INTERFACE IS NOT PUBLIC Doc ID: Note:316583.1
If you are trying to install 10g on Oracle Enterprise Linux 5, as I am, you will hit errors installing clusterware. The first note above describes how a workaround used for a Linux threading bug is no longer valid. So before you run the root.sh script you will need to modify some files.
Note: The first time I installed clusterware I didn't see any errors. It was only when I verified the install I noticed something was wrong and found this note.
The second metalink article describes how vipca (which is executed automatically when you run root.sh during the clusterware install) doesn't like Private Network IP's being used for your public interface. It describes how to execute vipca manually.
I'm not 100% finished yet so I may encounter more issues. I have to recover from a backup and start my clusterware install again. While I was installing the database software my laptop BSOD'd and it corrupted my shared disks.
