How does TVS compare with SYSB-II?

TVS, also known as Transactional VSAM or DFSMStvs, is IBM's solution to file sharing. Modifications or rewrites can be extensive depending on the batch job. Also, TVS uses a longer I/O path. This will slow down data centers running at capacity during peak demand times, regardless of file sharing. In order to use TVS, you must have VSAM RLS. In contrast, SYSB-II can run with or without VSAM RLS, and you don't need to make source-code changes.
