Problem determination skills
In a large-scale enterprise system such as the WebSphere® Application Server for z/OS® environment, diagnosis might require a variety of skills to progress from a symptom to fixing the underlying cause of that symptom.
Because WebSphere Application Server for z/OS exploits many of the qualities and services that are unique to the z/OS operating system,
diagnosing system-related problems might require skills in the following areas:
- Parallel sysplex
- TCP/IP
- Security Server (RACF®) or the equivalent
- Database systems such as DB2 Universal Database for z/OS
- UNIX Systems Services
You can find information for many of these topics in the publications available through the z/OS Internet Library.
Similarly, diagnosing application-related problems might require a variety of skills because of
the variety of application components that WebSphere Application Server for z/OS supports. Programmers who diagnose
application problems in the WebSphere Application Server for z/OS environment need some familiarity
with the following:
- The process of assembling, deploying, installing, and running server applications and clients in the WebSphere Application Server for z/OS environment.
- Various tools such as the WebSphere Application Server for z/OS error log, and the job logs for programs running on z/OS.
