Cloning Oracle Home from RAC to Stand-Alone

I cloned Oracle software before and it is a simple process: tar $ORACLE_HOME, copy the tar file to the new server, untar, run the cloning script which will register the new home with the inventory, and you are done! In theory, at least. Here is what actually happened:

Presentation and Interview at NoCOUG Spring Conference

NoCOUG Spring Conference 2010 is in just 10 days, I’ll be doing my two hour long presentation — Demystifying Oracle RAC Workload Management. If it’s your local conference, I hope you can attend and say hello. You might also want to download the whitepaper that I put together few years ago for Hotsos Symposium — Oracle RAC Workload Management.
