The system records the activity of each process in two types of logs:
-
The system log (SUMLOG)
This central log stores information about all kinds of actions on the system.
-
Job logs
A separate job log is created for each job on the system and is stored in the job's job file. The system creates a job log for WFL jobs and other independent processes, as well as for CANDE and MARC sessions. The job log contains information about the job (or session) and its descendant tasks. Depending on the values of various task attributes and system options, the system might create a printout of the job log, called the job summary.
The following subsections explain how the programmer and system operator can control the contents of these logs and the generation of reports from these logs.
