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:
- They can be required by non-CICS regions such as batch jobs or a CICS data sharing
server.
- They must be consistent across several CICS regions.
- They can be required by both CICS and non-CICS regions.
- 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:
- Adding these modules, as required, to an existing APF-authorized library
defined in the MVS linklist, or
- Defining SDFHLINK itself as an APF-authorized library and including it
in the MVS linklist.
Compatibility with earlier CICS releases
Unless 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.
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 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:
- DFHDTSVC and DFHDTCV, because all regions using shared data tables must
use the same level of SVC code
- DFHMVRMS, the RESMGR exit stub, because CICS JOBLIB/STEPLIB data sets are unavailable
at end-of-memory
