IMS Library Integrity Utilities

The architecture of IMS Library Integrity Utilities is centered around z/OS batch processing. The main components include the Integrity Checker, Consistency Checker, DBD/PSB/ACB Compare and Mapping utilities, and MFS Utilities. These components are implemented as executable modules that are invoked via JCL.

The Integrity Checker validates the structural integrity of ACB, DBD, and PSB libraries. The Consistency Checker verifies the consistency between different library members. The DBD/PSB/ACB Compare and Mapping utilities compare and map definitions across libraries.

The MFS Utilities provide comparison and reversal capabilities for MFS libraries. Communication between components occurs through the processing of input datasets and the generation of output reports or updated libraries. The utilities use standard z/OS datasets for input and output.

Input datasets typically include ACB, DBD, PSB, and MFS library members. Output datasets include reports detailing integrity checks, comparison results, and generated definitions. The utilities do not expose any APIs.

The utilities do not require specific network ports or external databases. The utilities are designed to integrate seamlessly with the z/OS environment, leveraging existing security and access control mechanisms. The utilities are accessed through JCL, with parameters specified in control statements within the JCL.

The utilities provide a robust and reliable solution for managing IMS libraries, ensuring data consistency and operational efficiency.
