Pete Silva talks with F5 Solution Engineer Chris Akker about Oracle Real Application Cluster (RAC) connection management.  This is a topic that has come up the last couple of days at the OpenWorld conference and the two discuss a solution that F5 is looking at testing and documenting.

Gravatar Hi all.
Interesting interview.

Gravatar Unless the app server is not configured to use connection pools but instead opens a unique connection per request the problem are as follows:
1. The app needs to log into a connection so the BIG-IP LTM would need to make 2 or more logon connections per VIP logon to allow the traffic to move in a transparent configuration.
2. Event if you create two or more VIPs that are then configured to use nodes that are in two or more server pools you need to do something to rebalanced the work load after the recovery of a server node. (a three node cluster, one node goes down all the work moves to one of the remaining two nodes, when the failed node is brought back on line unless app boxes kill one of their connection pools the no work would move back to the recovered node.)
