With WebSphere® Application Server Hypervisor Edition Intelligent Management Pack, the on demand router (ODR) is automatically tuned based on the virtual resources that are allocated to the virtual image. While the automatic tuning attempts to optimize your virtual system for performance, you can modify the applied parameters to meet the specific needs of your application.
When you deploy Intelligent Management Pack to run in a cloud group, two automatic ODR tuning parameters are applied: the Java virtual machine (JVM) heap size is set and ODR caching is automatically disabled. The heap size of the JVM is based on the allocated virtual memory, and ODR caching is disabled by default since IBM HTTP Server can already perform this function in a deployment topology. Depending on your application and performance needs, you can complete the following steps to modify the automatic ODR tuning parameters.
