Administer instances of WebSphere Application Server

The WebSphere Application Server product includes a default instance that consists of a single application server. The application server, named server1, contains the administrative console application, a default application, and the install verification application.

The use of multiple instances allows you to create multiple WebSphere Application Server environments that are completely isolated from one another. For example, you can create separate instances for application development and application testing, or you can create one instance with security enabled and one with security disabled.

You can run your applications in any of these environments:

The instance management scripts for WebSphere Application Server are shipped in the /QIBM/ProdData/WebAS5/Base/bin directory.
