In the previous chapter we learned how to schedule a job. In this chapter we will learn how to process a scheduled Job.
Once the job is scheduled it is up to the system to process the job based on how the job was defined (Steps and Start Condition). The Batch Scheduler initiates the start of background jobs at the specified starting time. The Dispatcher dispatches this request to the appropriate background (batch) work process. Remember: The actual processing of the job steps takes place in the work process.
To display the work processes for a particular application server, use the menu path “Tools -> Administration -> Monitoring -> System Monitoring -> Process Overview” (or transaction “SM50”).
After a background job has been initiated, start & end modules are automatically generated. Each of these modules puts an entry into the job log.
During the execution of each step in a background job, entries are made to the job log with any “MESSAGE” statements in the job’s programs or with any job-progress messages from the system.
Also, “WRITE” statements within a program will create a list. Printing specifications can be determined when scheduling each job step (i.e., print list immediately or put list in print spool). Only one list is possible for each job step.
