EPIC Modernization Guide

EPIC provides disk and tape management capabilities for zVSE/VSEn environments. It automates tasks such as backup, restore, and archiving, improving efficiency and reducing manual intervention.

EPIC supports various tape formats commonly used in mainframe environments, including 3480, 3490, 3590, and LTO cartridges. It handles different recording densities and data compression techniques.

EPIC uses standard VSE/ESA catalog management facilities to track datasets and volumes. It integrates with the VSE librarian to manage program libraries and source code.

Common commands include BACKUP to create dataset backups, RESTORE to recover datasets, ARCHIVE to move data to long-term storage, and RECYCLE to manage tape volumes. For example: BACKUP dataset.name TO tape.volume.

EPIC uses configuration files to define storage pools, tape libraries, and backup policies. These files are typically maintained by system administrators and specify parameters such as retention periods and compression options.

EPIC does not expose standard APIs like REST or SOAP. Integration is typically achieved through command-line scripting or by invoking EPIC commands from within VSE/ESA batch jobs.

By automating disk and tape management tasks, EPIC reduces the need for manual intervention, minimizing the risk of human error and freeing up IT staff to focus on other priorities. It also optimizes storage utilization and reduces costs associated with data storage.

EPIC helps organizations meet compliance requirements by providing features for data retention, archiving, and audit logging. It ensures that data is stored securely and can be retrieved when needed for regulatory purposes.

EPIC supports authentication through VSE/ESA security mechanisms, such as user IDs and passwords. It integrates with external security systems like RACF for centralized user management.

EPIC uses an access control model based on VSE/ESA security features. Access to datasets and volumes can be restricted based on user IDs and security profiles.

EPIC provides audit logging capabilities to track user activity and system events. These logs can be used to monitor security and compliance.

EPIC provides a command-line interface (CLI) for administrative tasks. It also offers a GUI for monitoring and managing disk and tape resources. User management is handled through VSE/ESA security administration tools.

Key configuration parameters include storage pool definitions, tape library configurations, backup schedules, and retention policies. These parameters are typically defined in configuration files.

EPIC provides monitoring capabilities through its GUI and command-line interface. It generates logs that can be used to track system activity and identify potential issues.
