If you use .NET as your primary Content Delivery technology, you can configure the JVM for all .NET services and .NET Web application. Regardless of your technology, you can also run the JVM in server mode.
Configuring the JVM for Windows services and .NET Web applications Content Delivery Server Roles running as Windows services or .NET Web applications start a Java Virtual Machine (JVM). You can specify switches for these JVM calls. (To configure JVM calls from Java Web applications, refer to the documentation of your Java/JSP Web application server.)
Running the JVM in server mode The Sun Java Virtual Machine (JVM) used by Content Delivery services can run in Client or Server mode. You can run Java applications using the server virtual machine by modifying the jvm.cfg file
