LIBRMVS

The architecture of LIBRMVS is designed to facilitate the migration of LIBR backups from z/VSE to z/OS. The main components include the Backup Extractor, Data Converter, and Dataset Creator. The Backup Extractor reads the LIBR backup files, handling the specific format and structure of the z/VSE backups.

The Data Converter performs any necessary transformations, such as character set conversions or data format adjustments, to ensure compatibility with the z/OS environment. The Dataset Creator then writes the converted data to the target z/OS datasets. Communication between components is primarily through z/OS I/O operations.

The product uses a configuration file to store settings for character set conversions, data format mappings, and other operational parameters. There are no external databases or storage mechanisms used beyond the input LIBR backup and the output z/OS datasets. Network requirements are minimal, as the process typically runs on a single z/OS system.

The primary command is `LIBRRESTORE`, which orchestrates the entire process. DATASET)`.
