Re: Oracle Parallel Server and 24x7 availability

This will be short and sweet.

I use it. I like it. I would recommend it. Raw devices aren't that hard, infact I prefer them. It's not what is advertised, but it's still worth it. In oltp enviroments you will want to be cautious, although I read that 8.1.6 does have mode that eliminates the problem with pinging that can occur in oltp enviroments.
