Rocket JOB/SCAN

The architecture of Rocket JOB/SCAN comprises several key components designed for efficient JCL management on z/OS. The JCL Parser is responsible for parsing the JCL source code, breaking it down into its constituent parts. The Validation Engine then analyzes the parsed JCL, checking for syntax errors, dataset availability, and compliance with predefined standards.

The Formatting Engine provides the capability to reformat JCL according to organizational guidelines, improving readability and consistency. The Reporting Module generates reports on validation results and any identified issues. Communication between these components is primarily internal, managed through the tool's core processing logic.

The tool utilizes z/OS datasets for storing configuration files, JCL source code, and validation results. There are no specific port requirements, as it operates within the z/OS environment. The tool integrates with the z/OS security infrastructure, leveraging existing security profiles and access control lists (ACLs) for dataset access validation.

This design ensures comprehensive JCL validation, reformatting, and reporting capabilities, contributing to improved batch job reliability and developer productivity.
