Take a look at this ( if you don't want to download it from a site ending in .de ... find it somewhere else ).
Why you probably don't need RAC ... written by a real expert and former Oracle employee.
Unless you have some really strong experienced RAC DBA's ... you probably will end up with more downtime not less attempting something like this.
The regular uptime of most servers ( especially unix/linux ) ones does not have much downtime. Probably more than reliable enough for many/ most organizations.
RAC does do a good job of selling Oracle software licenses and can be helpful in certain cases. It is good experience on a resume for a DBA to have.
There's a ton of similar discussions here on cdos from the past. If you use the google groups interface you can search and find them pretty easily. Received on Wed Sep 02 2009 - 08:45:10 CDT
