Bursting

Enhanced Definition

In the context of IBM mainframe systems, **bursting** refers to the automated process of separating continuous-form printed output, typically fan-fold paper, into individual sheets or sets of sheets along their perforations. This post-printing operation prepares reports, statements, or other documents for distribution or further processing. It is a physical process performed by a specialized machine called a **burster**.

Key Characteristics

- Post-Processing Operation: Bursting occurs after a print job has completed and the output has been physically printed on continuous-form paper, often from an impact printer.
- Physical Separation: It involves a specialized mechanical device (a burster) that tears the continuous paper along the pre-perforated lines to create discrete documents.
- High Volume Capability: Bursters are designed for efficiency, capable of processing large volumes of output, often thousands of forms per hour, making them suitable for batch report processing.
- Forms Compatibility: Compatible with various continuous forms, including single-part forms, multi-part carbonless forms, and forms with pre-printed data or special features.
- Automated Feed and Stacking: Many bursters feature automatic feeding mechanisms and output stackers to streamline the process and minimize manual intervention.

Use Cases

- Report Distribution: Separating large batch reports generated by COBOL programs, such as daily transaction summaries, financial statements, or inventory reports, into individual sections for different departments or recipients.
- Customer Statements/Invoices: Bursting continuous-form printouts of customer bills, account statements, or invoices into individual mail-ready documents for external distribution.
- Payroll Checks/Stubs: Preparing continuous-form payroll checks or pay stubs by separating them into individual units, often followed by decollating if multi-part forms were used.
- Form Letters/Notices: Processing personalized form letters or notices printed in bulk for individual mailing or internal distribution to employees or stakeholders.

Related Concepts

Bursting is a critical physical post-processing step for output generated by batch jobs running on z/OS, particularly those producing reports via JCL and COBOL programs. It often follows printing operations managed by JES2/JES3 and might be preceded by decollating if multi-part forms were used, where carbon copies are separated. It's part of the broader output management ecosystem, ensuring that physical output is prepared for its final destination, whether internal distribution or external mailing, connecting the digital world of z/OS processing to tangible paper documents.

Best Practices:

Proper Forms Design: Ensure continuous forms are designed with clear, consistent perforations and appropriate margins to facilitate smooth bursting and prevent paper jams.
Regular Burster Maintenance: Perform routine cleaning, lubrication, and adjustment of the burster machine to ensure optimal performance, prevent paper jams, and extend equipment lifespan.
Operator Training: Provide thorough training to operators on burster operation, troubleshooting common issues, handling different types of forms, and safety procedures.
Environmental Control: Operate bursters in a clean, dust-free environment with appropriate humidity levels to minimize static electricity and ensure reliable paper feeding.
Test Runs: Conduct small test runs when switching to new form types, after maintenance, or for critical print jobs to verify proper bursting alignment and prevent waste.
