InfoCenter Home > 6a: Administrative overview of Version 3.5
Looking for a summary of the tasks and resources you can manage with IBM WebSphere Application Server Version 3.5? See the quick reference, including links to instructions and descriptions of resource settings. Administrative modelIBM WebSphere Application Server provides administrators with a single system view of applications that are typically deployed across multiple machines. An administrator working on a physical machine can remotely administer resources located on another physical machine. These elements comprise the WebSphere administrative model:
Relationships among resources (the topology tree)The Topology tree demonstrates the relationships among resources. The relationship is the "containment hierarchy." The Topology tree is visible in the Java console (WebSphere Administrative Console). The containment hierarchy imposes a structure on the topology of the administrative domain. Becoming familiar with the hierarchy will make administrative tasks seem easier to accomplish. Anyone who has worked with directory and file representation systems, such as Microsoft Windows Explorer, has already been introduced to the concept of containment. Containment defines a relationship in which one resource is a part or "child" of another resource. If you have ever tried creating a directory in a file, you know that your file management program will not allow it. The directory-file containment hierarchy imposes the following rule: Directories can contain files, but files cannot contain directories. Similar relationships and rules exist among resources in the WebSphere Application Server administrative domain. For example, an application server resource can contain just one servlet engine. Some relationships depend on each other. Adding a servlet to the administrative domain requires a Web application. A servlet engine must exist to contain the Web application. Finally, an application server must exist to support the Web application containing the servlet. The containment hierarchy enables:
