OracleAS Cluster Migration

Question

I'm currently running in an active-passive configuration using OracleAS Cold Failover Cluster on the middle-tier. From reading the Oracle High Availability Framework documentation (http://download-east.oracle.com/docs/cd/B25221_04/core.1013/b15977/framewk.htm#CIHDGDGC) I understand that some of the benefits of going to an active-active OracleAS Cluster are increased scalability, performance and availability.
Should I consider migrating from an active-passive topology to an active-active topology to increase performance, scalability and availability on the middle-tier/infrastructure tier?
I understand there are several contributing factors in making such a decision and I will incorporate some performance testing eventually, but I wanted to know if there are any white papers, benchmark analysis or other documentation that might offer why an active-active might increase performance, scalability and availability.
Thanks for any thoughts, you guyz rock!
oh, BTW I'm running OAS 10.1.2.2.0 with OracleAS Cold Failover on two Dell 2950 Application Servers, Dual Core Xeon 5160 processors @
3.00GHZ, 8GB RAM, Microsoft Windows Server 2003 R2 Enterprise 64bit.

Answer 1

This is as simple as "Two heads think better that once", for this you will have two points (or more) of access to your applications, the process are split between servers and if one of the nodes fails, there are other to backup them. That's the only think that a Cold Fail Over cluster does, as well the administration is centralized if you have a nice configuration you will need to do only one configuration and all nodes will notice about it, finaly when you have a cold fail over cluster you have 50% of your potential workload in use, you have a server as a portrait that only is good to look at it but doesn't do nothing else, you dont need benchmarks or notes, this is really simple as it sounds.
