You may need to adjust JVM parameters to meet your testing needs. This can be done different ways depending on how you run your TestOptimal server. The most frequently changed parameters are the heap min and max size, adding jar packages to classpath.

If you are running TestOptimal as a standalone server, you can change JVM startup parameter in startTestOptimalServer.bat (in Linus, startTestOptimalServer.sh).

If you are running TestOptimal inside Eclipse or netBeans, the JVM parameters can be found in the property of run command.

Check Startup Arguments section in Server Configuration for more details about the server arguments.
