The argument is that unless you have some very very strong in house expertise you are likely to get less uptime ( more downtime ) in a RAC configuration than you are in a single server configuration. Plus that expertise has to be available pretty much immediately 24 x 7 x 365.

When you toss in the idea of running RAC on a windows based server that kind of magnifies this type of issue.

The reliability/availability of a unix/linux server tends to be in the 99.9 percent range. ( Some might argue that linux is more like 99.8 ).

Many many years ago "if" one was running oracle on a windows based server it was not uncommon to have to plan a weekly if not daily reboot of the server. Not necessarily oracle based problems but from the operating system.

That left a very bad taste in many people's experience of oracle on windows. Some if not all of those types of considerations may not be so valid any longer ( no real idea thank you very much ).

You probably won't get this much honest real world experience from a 3rd party oracle partner trying to push a RAC windows based system sales opportunity. Received on Thu Sep 03 2009 - 08:47:04 CDT
