Batch scheduling tools eliminated this concern by providing additional security features from the batch processing prospective, that is, provide user authentication for accessing the batch scheduling console, and group users into different levels of privileges according to their job role. For example, users in the application development group are allowed to define and modify jobs, users in the operation group are allowed to trigger or rerun jobs, and some third-party users may only have the rights to monitor a certain group of jobs.
In a mixed scenario, Job D will run if Job A or Job B and Job C is completed. During normal running, the batch scheduling tool constantly looks at its record of jobs to find out which jobs are eligible to be triggered according to the job's scheduling criteria, and then it will automatically submit the job to the operating system for execution. In most cases, the batch scheduling tool can control the total number of parallel running jobs to keep the machine from being overloaded. The execution sequence among parallel jobs can be based on individual job's predefined priority, that is, the higher priority jobs can be triggered before the lower priority ones.
Technically, all these steps can be combined within one processing unit (for example, steps with a JCL), but if a step fails during the processing, rerunning that specific step can be challenging. There are third-party products provided on the mainframe computers just for managing rerun JCL steps. On the distributed systems, it is up to the program designer to design their own way in the program to detect the error and handle such rerun action. In most cases, we have to restart the entire process from the beginning.
