I have some experience with it. We use it to protect some sap databases. It works reasable well, had some strange installation problems with older versions, but these seem to be gone now. One thing to remember is to have the parameter file (init or spfile) on a location that fails over to the other node, otherwise you probable end up with differences between parameter files and failing failovers.

About the licensing cost: you don't need to license the failover server only if there is only 1 failover server for your primary server and you only run the database for a maximum of 10 days per calendar year. And ff you run the database today for 2 hours on the failover server, it is counted as a full day. Otherwise you need to licence all servers.

Subject: Oracle Fail Safe

Does anyone have any experience with Oracle Fail Safe? We are looking into this as an option for High Availability of our Oracle databases running on Windows. It is supposed to work with MS clustering for server failover. From what I have found, it is available for standard or enterprise editions of Oracle, and there is no additional cost. Any opinions, good or bad, would be helpful.
