Startup order is used to configure which application in an application server will start first and which will start last.

1. In the WebSphere admin console, expand Applications > All applications.
2. Select All applications.
3. Select an application.
4. Select Startup behavior.

In this example, the startup order of the application is "1". Applications with a lower startup order value will start before applications with a higher startup order value. For example, if betaApp has a priority of "1", deltaApp has a priority of "2", and alphaApp has a priority of "3", betaApp will start first, followed by deltaApp, and finally alphaApp.
