Due

Enhanced Definition

In the context of mainframe operations, "due" refers to the state or condition where a specific task, process, report, or system action is expected or required to occur by a designated time, date, or event. It signifies an obligation or a scheduled completion point within the enterprise computing environment, crucial for meeting business and operational commitments.

Key Characteristics

- Time-Sensitive: Often associated with strict deadlines for batch job completion, report generation, data synchronization, or system maintenance, critical for subsequent business processes.
- Event-Driven: Can be triggered by specific events, such as the end of a business day, month, or fiscal quarter, prompting the execution of related "due" processes.
- Measurable: Performance against "due" expectations is frequently tracked via Service Level Agreements (SLAs) or operational metrics to ensure system reliability and efficiency.
- System-Managed: While the concept is business-driven, the actual enforcement and tracking of "due" items are often managed by sophisticated job schedulers (e.g., IBM Z Workload Scheduler, CA-7), monitoring tools, and application logic.
- Dependency-Based: The "due" status of one task often depends on the successful completion of preceding tasks, forming complex job streams and workflows.

Use Cases

- Batch Job Scheduling: A critical nightly batch job stream, including COBOL programs processing financial transactions, is "due" to complete by 6:
