This document provides a description of messages issued by z/Server including possible corrective actions. Every message has an 8-character identification and an associated message text.
Troubleshooting often requires knowledge of configuration settings, such as the name of the holder task, the scheduler task, and the user server task(s). Please see the z/Server Installation Guide for details about these settings.
Most messages only appear in the JESx job log in different DD names and not in the z/OS hardcopy log. True hardcopy log messages are marked.
