Specific exit program samples

Certain user exit points have sample programs that demonstrate how you can use the exit point in your global user exit programs.

Application associated data sample exit program: DFH$APAD
DFH$APAD is a sample global user exit program for the application associated data exit.

DFH$BMXT is a global user sample exit program for the basic mapping support user exits XBMIN and XBMOUT. This sample program shows how you can use the exits to modify mapped input and output data.
Data tables sample exit program: DFH$DTAD
DFH$DTAD is a sample XDTAD global user exit program. It demonstrates the use of the XDTAD user exit for shared data tables. Copybook DFHXDTDS defines the data tables user exit parameter list that is used in the sample.
Data tables sample exit program: DFH$DTLC
DFH$DTLC is a sample XDTLC global user exit program. It demonstrates the use of the XDTLC user exit for shared data tables. Copybook DFHXDTDS defines the data tables user exit parameter list that is used in the sample.
Data tables sample exit program: DFH$DTRD
DFH$DTRD is a sample XDTRD global user exit program. It demonstrates the use of the XDTRD user exit for shared data tables. Copybook DFHXDTDS defines the data tables user exit parameter list that is used in the sample.
Dump domain sample exit program: DFH$XDRQ
DFH$XDRQ is a dump domain sample global user exit program. It is designed to be invoked at the XDUREQ exit. DFH$XDRQ shows you how to manipulate the dump table entry and how to permit or suppress the dump.
Enqueue EXEC interface sample exit program: DFH$XNQE
DFH$XNQE is a sample global user exit program for the enqueue EXEC interface. It is designed to be invoked at the XNQEREQ and XNQEREQC exits. The program demonstrates three ways of adding a SCOPE value to EXEC CICS ENQ and EXEC CICS DEQ requests, to make the requests apply to multiple regions within the sysplex.
File control state sample exit program: DFH$REQC
DFH$REQC is a sample global user exit program for use with the file control state program. It is designed to be invoked at the XFCSREQC exit. DFH$REQC allows you to check VSAM error flags after file requests have been acted upon and, optionally, to write messages and data areas to a system console or a transient data queue.
File control recovery sample exit program: DFH$FCBF
DFH$FCBF is a sample exit program that is designed to be invoked at the XFCBAIL exit for handling backout failures.
File control recovery sample exit program: DFH$FCBV
DFH$FCBV is a sample exit program that is designed to be invoked at the XFCBOVER exit. It allows you to decide whether to allow an update to be backed out, following a batch update run that has overridden retained locks.
File control recovery sample exit program: DFH$FCLD
DFH$FCLD is a sample exit program that is designed to be invoked at the XFCLDEL exit. It allows you to perform logical deletion of records from a VSAM ESDS data set or a BDAM data set during backout.
Function-shipping/DPL queue control sample exit program: DFHXIS
DFHXIS is a sample global user exit program that controls the queueing of function-shipping and DPL requests.
HTTP client sample exit programs (DFH$WB*)
CICS includes four sample programs for use with the Web domain exits XWBOPEN and XWBAUTH. The sample programs are DFH$WBPI, DFH$WBEX, DFH$WBX1, and DFH$WBX2.
Interval control EXEC interface sample exit program: DFH$ICCN
DFH$ICCN is an interval control EXEC interface sample exit program. It is designed to be invoked at the XICEREQ exit.
Log manager domain sample exit program: DFH$LGLS
DFH$LGLS is a sample global user exit program for the XLGSTRM exit point. It shows you how to change parameters such as the model log stream name that is used by the MVS™ system logger when it creates a new log stream dynamically.
Message domain sample exit programs (DFH$SXP*)
CICS includes six sample programs that are called at the XMEOUT exit to complete specified tasks such as suppressing or rerouting messages. The sample programs are DFH$SXP1, DFH$SXP2, DFH$SXP3, DFH$SXP4, DFH$SXP5, and DFH$SXP6.
MRO and APPC session queue management sample exit program: DFH$XZIQ
DFH$XZIQ is a sample XZIQUE exit program that you can use as a base to design your own global user exit program. It implements the same basic function provided by the QUEUELIMIT and MAXQTIME parameters on the connection resource definition.
Session queue management sample exit program for IPIC connections: DFH$XISQ
DFH$XISQ is a sample XISQUE exit program that you can use as a base to design your own global user exit program. It implements the same basic function provided by the QUEUELIMIT and MAXQTIME parameters of the IPCONN resource definition.
IPIC queue control sample exit program: DFH$XISL
DFH$XISL is a sample XISQLCL exit program for controlling the queueing of START NOCHECK requests that are scheduled for an IPIC connection.
Pipeline sample exit program: DFH$PIEX
DFH$PIEX is a sample global user exit program that provides sample processing for the XWSPRROO global user exit.
Transaction abend sample exit program: DFH$PCTA
DFH$PCTA is a sample global user exit program for the XPCTA exit point. It is designed to be invoked at the XPCTA exit to test whether the abend was caused by a storage protection exception condition.
The transient data write-to-terminal program (DFH$TDWT)
DFH$TDWT is a sample program that sends transient data messages to a terminal or printer. You can use it to send messages from a single transient data queue, or from several queues, to one terminal.
Terminal-not-known sample exit program: DFHXTENF
DFHXTENF is a sample global user exit program that handles terminal-not-known conditions that arise from START and ATI requests. It is designed to be invoked at the XALTENF or XICTENF exit.
