EPA2

EPA2's architecture is centered around a batch processing model on z/OS. The main components include the EPA2 program, the JCL interface, and the dataset I/O. The EPA2 program is the core executable that performs the analysis.

It reads load libraries specified in the JCL's `SYSLIB DD` statements. The JCL acts as the primary interface for configuring and executing the analysis. It defines the input load libraries, output report datasets, and various processing options.

The dataset I/O component handles the reading of load libraries and the writing of report data. The tool uses standard z/OS file formats for input and output. The communication between components is managed through JCL control statements and dataset definitions.

The EPA2 program processes the load modules and extracts metadata. The tool generates reports in various formats, including text and CSV. The reports contain details about the compiler version, options, and other relevant information.

The tool does not expose APIs. The tool does not have built-in authentication mechanisms. Access control is managed through z/OS security features, such as RACF or similar security products.

The tool does not perform encryption of data. Security is provided by the underlying z/OS environment. Sensitive data is protected through dataset-level security and access controls.

The tool does not have built-in audit logging capabilities. Auditing is handled by the z/OS system, which logs all dataset accesses and JCL executions.
