COMPILES

The architecture of COMPILES is designed for high performance and scalability within the z/OS environment. The main components include the Compile Manager, Compiler Interface, and Job Executor. The Compile Manager is the central control point, responsible for coordinating the overall compilation process.

It receives compile requests, manages the job queue, and monitors the status of running compiles. The Compiler Interface provides a consistent interface to various compilers, including Enterprise COBOL, CA Easytrieve, Assembler, Enterprise PL/I, and CA IDMS DML. It handles the communication with the compilers, passing the necessary source code and options, and retrieving the compilation results.

The Job Executor is responsible for submitting the compile jobs to the z/OS system and monitoring their execution. It interacts with the z/OS Job Entry Subsystem (JES) to manage the jobs and retrieve the output. Communication between components occurs via internal system calls and TCP/IP.

The Compile Manager and Job Executor communicate using internal system calls for job control and status updates. The Compiler Interface uses TCP/IP to communicate with the compilers, which may reside on different LPARs or systems. COMPILES utilizes datasets for storing configuration files, job logs, and compile reports.

The configuration files define compiler settings, job submission parameters, and logging options. The system leverages the z/OS security manager for authentication and access control, ensuring secure operations. The CLI provides a command-line interface for administration and control.

The START, STOP, SUBMIT, STATUS, and REPORT commands are used to manage the compilation process. COMPILES' architecture is designed to maximize compile throughput and minimize resource consumption, providing a robust and efficient solution for mainframe compilation automation.
