Jobs exist to be read in, converted, classified, and ultimately run. Many factors can affect how, where, when, and if they will run, such as:

• Job Class
• Control of Initiators by JES2 or WLM
• Job Selection Priority
• Job Hold Status
• Member Affinity
• Scheduling Environment
• Job Name
• Number of other Jobs queued for Execution
• Configuration of Active Initiators
• Workload Manager Policy

This topic describes each of these factors and how they influence job flow during the execution phase.
