Oracle RAC SCAN is not compatibile with NAT (and thus with PCI DSS) failure scenario3: client might succeed DNS hostname resolution, might even be able to route to the the OracleVIPX IP is, but there is firewall somewhere in between (e.g. on the same box that is doing DNAT/TCP proxy) blocking “some client” to reach directly OracleVIPX on TCP/ yep, i can ping the SCAN. This is something i am unclear on, is there a difference between the SCAN and the cluster? on our DNS server i have the cluster entries with 3 ip address, but from the oracle doc it seems to say the SCAN is a different beast altogether, and mentions that my default the scan is mycluster-scan, is this correct, do i need to have DNS entries for mycluster-scan as well as. I found PDF about Oracle Single Client Access Name (SCAN). Using SCAN with Multiple Ports on the Same Subnet. For the purpose of allowing applications to maintain a distinguishable connect string on host / port level using one SCAN as the host or to enable port-based firewall configurations, SCAN can be set up to support more than one port for the same subnet.
