The J2EE Engine components have two types of properties: global and local. Global properties are common for all cluster elements while local properties are only valid for a specific cluster element.
Each property has a default and a custom value. The default value of a property is assigned by the time of its creation. A subsequent change to the value of this property assigns and changes its custom value, without affecting the default one. When, for example, a property value is changed using the SETSP and SETMP shell commands or the Visual Administrator, this property is saved as a local property for the cluster element on which the change is made. If this property already exists as a local property, the value is stored as local custom, else new property is created and the value is stored as local default.
For more information about changing properties with shell commands, see ADMIN command group in the Reference Manual.
For more information about changing properties with the Visual Administrator, see Accessing Components in the Administration Manual.
