This Redpaper is intended for system programmers and administrators who need an efficient way to identify problems, analyze them, and fix them so that they can deliver good support for the WebSphere Application Server for z/OS environment. IBM support and technical professionals and Java developers who work in the WebSphere for z/OS environment are also part of this targeted audience.
We identified possible problem areas that can be encountered in WebSphere for z/OS and arranged them into four specific problem phases corresponding to steps in the WebSphere for z/OS life cycle:
Phase 1: Installation, configuration and migration
Phase 2: Application deployment
Phase 3: Testing and running applications
Phase 4: System environment (production)
We give a general overview of the problem areas in the individual phases, explain how to analyze them, and provide valuable hints and tips for avoiding them.
