Administration Services 

Purpose

The J2EE Engine administration is based on the Java Management Extensions (JMX™) 1.1. For this purpose, several services are available that provide a means for working with MBeans:

Basic Administration Service

This service provides instrumentation of the kernel and the server components (services, libraries and interfaces). It also registers MBeans that can be used for managing a single cluster node or the whole cluster.

Generally the Basic Administration Service registers two logical types of MBeans:

●     Standard – provide standard functionality for start/stop, get/set properties, and so on. These MBeans are registered by default for all deployed components.

●     Specific – provide component specific functionality that varies from one component to another.

For more information about how to use MBeans with J2EE Engine, see Administration in the Development Manual.

Administration Adapter Service

This service is part of the distributed services level of the JMX infrastructure. It provides the following features:

●     Remote connector to the MBean server based on RMI/P4

●     Convenience interfaces for working with the MBeans registered by the Basic Administration Service. You can use these interfaces to invoke operations on the MBeans. These interfaces also provide methods for cluster administration and for viewing all registered MBeans.

●     A swing-based GUI for remote administration (the Visual Administrator tool)

●     Shell commands for console administration

The service also gives you the ability to access the MBeanServer remotely. To do this you have to lookup the Administration Adapter Service interface from the JNDI Registry

JMX Adapter Service

Creates the MBeanServer and registers all MBeans, except for those used for administration, which are registered by the Basic Administration Service. For more information, see JMX Adapter Service.

JMX Notification Service

Provides notifications for events connected with the MBeans. For more information, see JMX Notification Service.

Additional Administration Services

Two other services are available, which provide different types of administration:

●     Shell Administration Service – provides console administration using shell commands. For more information, see Shell Console Administrator.

●     Telnet Provider Service – provides remote administration using the Telnet protocol. The administration is done using shell commands. For more information, see Connecting and Working Using Telnet.
