Use administrative programs (JMX)

This topic describes how to use Java API to administer WAS and to manage the applications. We can administer WAS and the applications through tools that come with the product or through programming with the Java APIs.

The wsadmin scripting tool, the administrative console, and the administrative command-line tools come with the product. These administrative tools provide most of the functions that manage the product and the applications that run in WAS. We can use the command-line tools from automation scripts to control the servers. Scripts that are written for offer a wide range of possible custom solutions that you can develop quickly.

Investigate these tools with the Java APIs to determine the best ways to administer WAS and the applications. For information on the Java APIs, view the application programming interfaces documentation.

WAS supports access to the administrative functions through a set of Java classes and methods. We can write a Java program that performs any of the administrative features of the WAS administrative tools. We can also extend the basic WAS administrative system to include your own managed resources.

We can prepare, install, uninstall, edit, and update applications through programming. Preparing an application for installation involves collecting various types of WAS-specific binding information to resolve references that are defined in the application deployment descriptors. This information can also be modified after installation by editing a deployed application. Updating consists of adding, removing or replacing a single file or a single module in an installed application, or supplying a partial application that manipulates an arbitrary set of files and modules in the deployed application. Updating the entire application uninstalls the old application and installs the new one. Uninstalling an application removes it entirely from the WAS configuration.

Perform any or all of the following tasks to manage WAS and your Java EE applications through programming.



Depending on which tasks you complete, we have created your own administrative program, extended the WAS administrative console, connected and managed vendor servers, or managed the applications through programming.

What to do next

We can continue to administer WAS and the applications through programming or in combination with the tools that come with the WAS.
