Configuring the JVM
As part of configuring an application server, you might define settings that enhance the way your operating system uses of the Java™ virtual machine (JVM).
About this task
The JVM is an interpretive computing engine that is responsible for running the byte codes in a compiled Java program. The JVM translates the Java byte codes into the native instructions of the host machine. The application server, being a Java process, requires a JVM to run and to support the Java applications running on it. JVM settings are part of an application server configuration.
To view and change the JVM configuration for an application server process, use the Java virtual machine page of the administrative console or use wsadmin scripts to change the configuration.
