NetComrad and Dan:

Guys, unfortunately, I'm not in work today so I can't get to the RAC to rerun the CVU (Dan's posting).

NetComrad: Unfortunately, my facility is more geared towards Windows based systems. This differes from the majority of Oracle installations in my organization. Yea, I have some reasonably nice HPUX  boxes (running Oracle) but unfortunately, we're more geared towards Windows. Trust me, I'd love to do this on Linux. I do have a request for some money to replace our single K580 HP-UX box with a couple of smaller, faster, fibre based systems specifically so I can test RAC under UNIX.

Dan: It seems to me I did go through a verification when I installed the 10g clusterware. There were some items I had to cleanup and I did. Once I did that, it installed flawlessly and I was able to create a database, etc., etc. The only problems are the periodic random crashes (they don't happen often).

I also experienced this same behavior with Oracle 9i RAC under VMware, though in that setup, I only lost instances and didn't have entire virtual machines randomly crashing. Once it was put on real hardware, I haven't had a single crash or lost instance and it's been over a year now.

You are correct in from what I've read, this isn't supported. Luckily, it's NOT production. Still, I find it a bit strange that Oracle themselves send out RAC by example DVDs that make use of VMware's products. And I believe other people do have this working without the random crashes.

I'll see if I can get through the CVU next week, as soon as possible. If it's anything like my 9i RAC under VMware experience - it's going to return no errors.

Thanks for everybody's help and suggestions...
