SYSDATA in CONTROL-M


SYSDATA:

SYSDATA is the term used to designate the data in three job sysout datasets:
• job log (console messages)
• expanded JCL
• system output messages

SYSDATA datasets are usually produced for each execution of a job or
started task. However, not all three datasets are necessarily present in all
cases. For example, in JES2, if a job is canceled by the operator before
execution, the system output messages dataset might not be produced.
For jobs, the output class for this data is defined by one of the following:
• MSGCLASS parameter on the job card, which is added or overwritten by
CONTROL-M during job submission.

• JCL job-level //OUTPUT statement using the JESDS subparameter.
• Default values defined in JES initialization parameters.
• For started tasks, the output class for this data is defined in JES
initialization parameters.

When CONTROL-R is installed, it uses the SYSDATA to analyze the
execution of a job order, beginning with the archived SYSDATA of the most
recent non-restarted run.
