CICS Transaction Server

To exploit the functions that VSAM RLS provides, you need CICS® Transaction Server (CICS TS) Version 1 Release 1 or later, which provides these features:

VSAM RLS support, enabling CICS systems to share the VSAM data sets directly rather than function shipping to a file owning region
Application programming interface (API) extensions for VSAM RLS
The CICS TS log manager
The CICS TS recovery manager

If you are running DFSMStvs and CICS TS, a compatibility PTF is required for CICS TS because DFSMStvs support requires some changes to the VSAM problem determination information used to report locking conflicts. The problem determination information is used by both DFSMStvs and CICS TS.
