Even though all Forms processes might at one point call out to Java, if only a subset of these call out to Java at any given point in time, only as many JVMs as are necessary at peak usage, need be started. The recommended location to define custom parameter types, would be in src/test/java/com/example/ParameterTypes.java. JVM pooling makes provisions for sharing a limited number of JVMs among all participating Forms processes. The other parameters take on their default values.

In that case, it is possible to have multiple "child" JVMs for the same JVM controller which get created dynamically as needed. Leave Log Directory blank to use the log location for the default JVM controller. When you delete a named configuration section, you delete all the information within it. Copy the hub.jvmoptions.dist file and save it as hub.jvmoptions or Create a hub.jvmoptions file in this directory and paste the contents of the sample configuration file into it. Each Orders application that runs sends requests to ordersJVM. Alternatively, this information can also be passed as a parameter in the URL for invoking the Forms Application.
