Modules required to use the console message-handling facilities
To use the console message-handling facilities that are provided by the MVS™ subsystem functions of CICS®, the CICS modules, DFHSSEN, DFHSSGC, DFHSSMGT, and DFHSSWT must be available at MVS IPL time.
- DFHSSEN
- The module that cleans up CICS resources at end-of-memory and at end-of-task.
- DFHSSGC
- The subsystem generic connect module that connects an active CICS region to the CICS subsystem.
- DFHSSIN
- The CICS subsystem initialization module.
- DFHSSMGT
- The subsystem message table that contains the text of messages for the subsystem interface modules.
- DFHSSWT
- The subsystem interface write-to-operator (WTO) router that determines whether to route WTO calls to the appropriate CICS-dependent modules.
These modules must reside in the LPA or in an APF-authorized library in
the MVS linklist:
- The modules DFHSSIN and DFHSSMGT, installed in the hlq.SDFHLINK library, must reside in an APF-authorized library in the MVS linklist.
- The DFHSSEN module, installed in the hlq.SDFHLPA library, must reside in the LPA.
- The modules DFHSSGC and DFHSSWT, installed in the hlq.SDFHLPA library, must reside either in the LPA or in an APF-authorized library in the MVS linklist.
The current versions of these modules are compatible with earlier CICS releases that support console message handling.
For information about adding modules that are installed in the hlq.SDFHLINK library to the MVS linklist, see Installing CICS-required modules in the MVS linklist.
