Re: Real Application Cluster (RAC) - Access Transperency

In a TAF RAC cluster installation the client connection layer (in this case Oracle NET, Net8 or SQL*Net) is "cluster aware" and thus will handle the failover (or even load balancing).

All applications will connect through this connection layer resulting a transparent failover from the viewpoint of the application.

Thank you for your help pointing this out.
