6: Administer applications

Typically, one or more application developers with different areas of expertise (such as architects, Java programmers, legacy programmers, and Web programmers) design and create a new application or migrate an existing application to support new Java specifications based on input from business users.

After the files comprising an application have been developed, then the application can be added to the application server for access by users. This section of documentation helps you learn the flow of administrative activities, whether you are a code developer introducing an application into a test environment, or an administrator responsible for the production environment.

A feasible end-to-end administrative procedure

The following procedure provides links to more information about each step. To practice the procedure using an application provided with WebSphere Application Server, perform the application configuration and deployment tutorials.

  1. Install the product. Plan and install a topology comprised of one or more product installations and the necessary prerequisites.

    • Who: Lead architect, network administrator, systems administrator
    • How: See components section, installation section .
  2. Install the application files. Install the application into the test environment.

  3. Configure the runtime, supporting resources, and the application itself. Create application servers and other resources that will support applications.

  4. Test the application. Test the application prior to enabling runtime security so that you can tell the difference between security-related problems and other problems.

    • Who: Systems administrator
    • How: Using a Web browser or other application client -- see the tutorial for examples
  5. Configure runtime security. Configure and enable security in the application server runtime.

  6. Test application security. Test the application again, this time with security enabled.

  7. Perfect the test environment. Debug and verify the application in the test environment. Perform preliminary tuning.

    • Who: Tester, systems administrator
    • How: Using the administrative console
  8. Port the application to production environment. Configure the production environment and move the application there.

    • Who: Network administrator, systems administrator
    • How: Using the administrative console
  9. Manage the production environment. Manage the production application, tuning the application files and configuration as needed. Update the production application as needed.
