EAServer supports several JDK versions, and each JDK version can support multiple VM types such as Server Hotspot, Client Hotspot, and Classic. You specify the JDK version and VM type when starting the server from the command line, or for servers that run as Windows services, with the command that you run to install the service. For details, see “Starting the server” in the EAServer System Administration Guide.
As a general rule, you should use the Server Hotspot VM in the latest supported JDK version. However, always consult the EAServer Release Bulletin for your platform for updated recommendations.
For more information on Java Hotspot technology, see the Sun Microsystems white paper Java HotSpot Performance Engine Architecture.
