Java Properties

These properties relate to the Java Virtual Machine (JVM) that runs the OpenFusion Services.

JVM Information

This property displays information about the Java Virtual Machine that the Service is running in, for example:

build JDK-1.2.2_006, native threads, symcjit

This information is only displayed while the service is running.

Property Name

JVM.Info

Property Type

DYNAMIC

Data Type

STRING

Accessibility

NO

JVM Flags

These flags are passed to the Java Virtual Machine used to run the Service.

Property Name

JVM Free Memory

Displays the free memory available to the Java Virtual Machine that the Service is running in.

This information can only be refreshed while the Service is running.

Property Name

JVM Total Memory

Displays the total memory available to the Java Virtual Machine that the Service is running in.

This information can only be refreshed while the Service is running.

Use Xbootclasspath

If this property is checked, the JVM is passed the -Xbootclasspath flag when the service is started.

The -Xbootclasspath flag causes the service to use the OpenFusion classes and not those supplied with the JRE. A side-effect of using -Xbootclasspath is the inability of the JVM to find shared libraries.

For a Singleton to register itself with a running Naming Service when it is started, this property must be checked.

Property Name

BOOLEAN
