This environment is intended for use in a program development, testing, or non-XRF production environment. CICS Subsystems Supported IMS DB can be connected (using the IMS database resource adapter) to CICS, and IMS TM can be connected (using the appropriate TM interface) to CICS. Minimum CICS levels are documented in the Release Planning publications. DB2 Subsystems Supported IMS TM can be connected to DB2 products. Supported DB2 products and release levels are documented in the Release Planning publications.
Accessing IMS TM IMS TM supports an SNA-based network and a TCP/IP network in collaboration with the z/OS Communications Server. Application programs can use IMS Message Format Services (MFS) to define the transaction message input and output metadata and to build the input and output screen for an interactive terminal end user. MFS parses the data to manage the input and output data streams for the application program. To provide network protocol transparency, transaction message integrity, and communication device-independent application programming, IMS TM includes a queue manager.
To provide network protocol transparency, transaction message integrity, and communication device-independent application programming, IMS TM includes a queue manager. Figure 3-1 shows the main interfaces to IMS TM: Open Transaction Manager Access (OTMA), IMS Connect, virtual telecommunications access method (VTAMŴ), and advanced program-to-program communication (APPC). IMS TM also provides two ways to couple multiple subsystems for application program communication: 舦 Multiple Systems Coupling (MSC).
