Parts of a Batch
A Batch Definition contains instructions in the form of components that define both the schedule and the components that are executed. When the Batch Definition is scheduled on the Manager, it creates a Batch Entry, which typically waits until its scheduled time, then creates a Batch Execution. The Batch Execution then creates Service Sessions, PDriver Jobs, or other Grid workloads that are executed on the Manager.
A Batch Definition contains Batch Components; each of which defines what the Batch Definition does. When a Batch Definition is scheduled, it creates a Batch Entry, which is an instantiated Batch Definition and runs as defined by the Batch Components. When it runs, it creates a Batch Execution, which then runs the components according to the definition.
