White paper: Using Transactional VSAM to let CICS and batch access VSAM files concurrently
Transactional VSAM (DFSMStvs, or TVS) is an optional z/OS feature that enables batch jobs and CICS transactions to concurrently update shared VSAM data sets. Multiple batch jobs and CICS transactions can process with the same VSAM data sets. Data integrity is ensured for both CICS and concurrent batch updates. In this white paper, you will learn more about how this option works, the features, and the issues to consider.
