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.
