Re: Data Guard Standby Database

I beg to differ.
With stand by server we are usually talking about short periods that the server needs to be able to serve the company. 
Those periods will be far apart.

The ROI usually will not justify going with RAC for this kind of activity.
Of course, if business requirements demand otherwise then the ROI does not count. 
For example:
Both RAC servers are now at 75% capacity.
Single, same configuration, server will not be able to meet the load and will cause a slow down. If this slow down is not acceptable for short period of time you need also RAC for the stand by.
