6.5: Maintaining and updating applications

This section includes information about monitoring daily operations and the health of applications, updating applications, and performing necessary tasks after updating an application (such as stopping a process and starting it again).

To update the contents of an application, use the Application Assembly Tool. Typical maintenance tasks include adding or editing assembly properties, adding or importing modules into an application, and adding enterprise beans, Web components, and files.

What should you do if an application changes?

Depending on what you have changed, you can sometimes replace an application with a newer version, or modify configuration settings or application bindings, without having to disrupt the application server or the installed application.

Article 6.5.1 discusses various changes and the minimum actions you must take to update the application in your server runtime.

In the very worst case, you will need to:

  1. Reassemble the application, using the Application Assembly Tool.
  2. Uninstall the current version of the application.
  3. Install the new version of the application.
