The Instance System Properties page displays a list of the Java system properties that are set for the selected GlassFish Server instance. Java system properties are passed to the Java application launcher through the -D option of the Java application launcher whenGlassFish Server is started.
These properties override property definitions for port settings in the instance's configuration. Predefined port settings must be overridden if, for example, two clustered instances reside on the same host. In this situation, port settings for one instance must be overridden because both instances share the same configuration.
For information about predefined port settings in a configuration, see Predefined Configuration System Properties.
For each property, the following information is displayed:
The name of the system property.
The value of the property that is set for the selected instance. This value overrides the default value.
The value that is set for the property in the named configuration that the instance references. This field is read only.
The Additional Properties table also contains the following options.
Button to add a property. Clicking this button adds a row to the Additional Properties table.
Button to delete one or more selected properties. Any property that is deleted reverts to its default value or, if no default value is set, is undefined.
