z/OS Diagnostics and Debugging
5 days

This class is a lecture-workshop for experienced systems programmers with a focus on using the tools available to narrow down the scope of system problems, identify failed components and debug operating systems problems. Emphasis will be on problem diagnosis and “hands-on” exercises using the available tools.

AUDIENCE
This class is intended for experienced systems programmers with a good understanding of TSO/E, JCL and OS/390 functions.
