CICS-supplied modules required in the MVS linklist

CICS® supplies the modules listed below in the hlq.SDFHLINK library, where hlq is defined by the LINDEX parameter in the DFHISTAR installation job.

AMDUSREF
Alias of DFHTG640.
AXMSC
AXM server connection routines for CICS data sharing servers.
AXMSI
AXM subsystem initialization routine for CICS data sharing servers.
DFHDTCV
Connection validation subroutine for shared data tables.
DFHDTSVC
Shared data tables SVC services.
DFHGTCNV
Subroutine used by LOGR subsystem interface.
DFHLGCNV
Exit routine for LOGR subsystem interface.
DFHMVRMS
General MVS™ RESMGR exit stub.
DFHNCIF
Named counter server interface.
DFHNCOPT
Named counter server options.
DFHPD640
Dump formatting routine for use with IPCS.
DFHRPDUF
System dump formatting routine for ONC RPC.
DFHRPTRI
Trace interpretation routine for ONC RPC.
DFHRXSVC
RRS domain authorized services.
DFHSNNFY
RACF® CICS segment changes notification routine.
DFHSNPTO
CICS RACF dynamic parse TIMEOUT keyword print routine.
DFHSNVCL
CICS RACF dynamic parse OPCLASS validation routine.
DFHSNVID
CICS RACF dynamic parse OPIDENT validation routine.
DFHSNVPR
CICS RACF dynamic parse OPPTRY validation routine.
DFHSNVTO
CICS RACF dynamic parse TIMEOUT validation routine.
DFHSSIN
CICS subsystem that initializes the console message handling facilites.
DFHSSMGT
CICS subsystem message table that contains the text of messages for the subsystem interface modules.
DFHTG640
Link module for the CICS GTF trace printing load module DFHTRGTF.
DFHTR640
Link module for the CICS GTF trace printing load module DFHTR640.
DFHTT640
Link module used for trace interpretation.
Note:
It is not essential that DFHTT640 be included in the MVS Linklist, although it is recommended for the reasons given at the end of this list. If it is not in the linklist, an APF authorized library in the STEPLIB concatenation of the batch job is needed for every job which needs the module.
DFHXCSVC
External CICS interface (EXCI) SVC services routine.

These modules are supplied in an APF-authorized library in the MVS linklist because:

  1. They can be required by non-CICS regions such as batch jobs or a CICS data sharing server.
  2. They must be consistent across several CICS regions.
  3. They can be required by both CICS and non-CICS regions.
  4. The RACF dynamic parse routines are required by the Security Administrator who executes the ADDUSER or ALTUSER commands under TSO. For information about the RACF interface routines, see the CICS RACF Security Guide.

These modules are in the hlq.SDFHLINK library when you install CICS.

Ensure the modules supplied in SDFHLINK are available from an APF-authorized library in the MVS linklist by:

Compatibility with earlier CICS releases

Start of changeUnless otherwise stated, the CICS Transaction Server for z/OS®, Version 3 Release 1 levels of the modules in SDFHLINK are compatible with earlier releases of CICS. The CICSPlex® SM modules in SEYULINK are not compatible with earlier releases. CICSPlex SM modules in SEYULINK are release specific. See Updating the MVS linklist for more information about CICSPlex SM linklist modules.End of change

Note:
DFHPD640, DFHTG640, DFHTR640, and DFHTT640 are release dependant. If you run more than one release of CICS, ensure the correct versions are available (for example, DFHPD630 for CICS TS for z/OS, Version 2.3, DFHTG530 for CICS TS OS/390®, Version 1 Release 3).

CICS shared data tables modules for the MVS linklist

CICS supplies the following modules, for the shared data tables facility, in the hlq.SDFHLINK. If you intend using the shared data tables facility, ensure that these modules are available in the MVS linklist or the MVS link pack area:
