Systems programmers or applications programmers that need a better understanding of the z/OS dumps and dump reading.
This class is an introduction to reading dumps. Topics will include examining control blocks, recovery/termination management, using IPCS, and abend types.
The course will focus on several dumps to extract various causes of failures, and examining control blocks for pertinent run-time information. Specifically S0C4 abends will be examined, as being more variable than many of the common errors.
Diagnosis will focus on using formatted printed dumps, as well as dumps that are processed by IPCS. Using IPCS, various tools and commands will be reviewed to illustrate how diagnostic data can be extracted from a machine-readable dump. Exercises include several dumps, as well as examining memory contents using various tools.
TSO/ISPF knowledge and z/OS basics.
