| Re: Multiple Web (Apache/Tomcat ) and OAS server
Raghu,
First - OTM fully supports multiple web servers and just requires a load balancer that maintains sticky sessions, either based on cookies or source IP. This is often utilized in order to accommodate high user and/or integration loads.
Next - if your volumes are really that high, I would highly recommend looking towards WebLogic as your primary OTM server -- the performance of the JRockit JVM can be several times that of the Sun JVM and will help you scale much higher on the same hardware.
As for multiple app servers - you're looking at the OTM SCA (scalability) functionality and it really requires an expert to analyze the need, determine the right type of SCA (active/active, active/passive, functional split or domain split) and help configure it. This is supported by both OAS and WebLogic.
