This section provides information about how to troubleshoot a problem with your IBM software.
- Installing maintenance packages
- This topic describes how to use the IBM Update Installer for WebSphere Software to install interim fixes, fix packs, and refresh packs. The Update Installer for WebSphere Software is also known as the update installer program, the UpdateInstaller program, and the Update installation wizard
- Debugging applications
- To debug your application, use your application development tool (such as Rational Application Developer) to create a Java project or a project with a Java nature. You must then import the program to debug into the project. By following these steps, you can import the WebSphere Application Server examples into a Java project.
- Adding logging and tracing to your application
- Designers and developers of applications that run with or under WebSphere Application Server, such as servlets, JavaServer Pages files , enterprise beans, client applications, and their supporting classes, might find it useful to use Java logging for generating their application logging.
- Diagnosing problems (using diagnosis tools)
- The purpose of this section is to aid you in understanding why your enterprise application, appserver, or WAS is not working and to help you resolve the problem. Unlike performance tuning which focuses on solving problems associated with slow processes and un-optimized performance, problem determination focuses on finding solutions to functional problems.
- Troubleshooting WebSphere applications
- For various components that might have failed, this section summarizes how to detect, confirm, and solve the resulting problem. The instructions are specific to various application types. For example, you can focus on troubleshooting access problems for an enterprise bean application, or a problem that presented itself as soon as you enabled security.
