Oracle Fail Safe
Posted on 2010-08-20
Can somebody explain how failsafe works from a networking point of view.
Does the primary publish a virtual IP address; the primary and secondary share this IP address and and MAC address and following fail-over, the secondary just answers the same requests as the primary.
Or do they share an IP address but have different MAC addresses, so a re-ARP is required by the client is required, or is action required by the client to re-initiate a connection to the secondary server after fail-over (i.e. a specially written client is required?
