VSAM Assist

The architecture of VSAM Assist centers around several key components: the Backup Engine, Restore Engine, Data Integrity Checker, and JCL Interface. The Backup Engine handles the creation of backup datasets, while the Restore Engine facilitates data recovery. The Data Integrity Checker verifies the consistency of the backed-up data.

The JCL Interface provides the primary means of interaction, allowing users to submit jobs and specify parameters. Communication between these components is managed internally within the z/OS environment. The product uses VSAM datasets for storing data and relies on standard z/OS storage mechanisms.

There are no specific network ports required for operation, as it operates within the z/OS environment. The primary administrative interface is through JCL. User management is handled through the z/OS security manager, such as RACF, which controls access to datasets and VSAM Assist commands.

Configuration parameters are specified within JCL control statements. Monitoring and logging are provided through z/OS system logs, which record job status, errors, and other relevant information. Compared to other VSAM backup solutions, VSAM Assist's architecture emphasizes data integrity and streamlined operations.
