You can configure different Java settings for the controller (the Silk Performer Workbench) and for your remote agents. This means that you do not need to maintain identical Java environments (Java versions, settings, directories) for your controller and agent machines. For agents, a JRE is sufficient, but on the controller, usually a JDK is required.
If a class or .jar file is not found on the agent machine within the specified path, the local data directory will be searched in addition.
There is a corresponding profile settings tab at that pulls its initial values from the remote agent settings at . It is the values on the active profile tab that are actually applied to remote agents at test time.
