Using EXCI sample application programs

CICS® provides a number of sample programs that are designed to help you in writing your own application programs. To help with writing programs that use the external CICS interface, CICS provides sample MVS™ client programs and a sample CICS server program.

The samples show you how to code client applications that use both the EXCI CALL interface and EXEC CICS LINK command.

Description of the sample applications

The sample external CICS interface programs are included on the CICS Transaction Server for z/OS distribution tape.

Two sample MVS client programs are supplied. One is provided in assembler language, COBOL, C, and PL/I. The other is only provided in assembler. The sample CICS server program is provided in assembler only. Assembler language programs are in source and executable form. COBOL, PL/I, and C programs are provided in source form only. Each version of the client program has basically the same function, but programming methods vary somewhat according to the language used.

The sample programs, shown in Table 23, are supplied in source form in CICSTS31.CICS.SDFHSAMP. The sample assembler server program is also supplied in executable form in CICSTS31.CICS.SDFHLOAD. The assembler client program is supplied in CICSTS31.CICS.SDFHEXCI.

Notes:
  1. The assembler versions of the client program use BSAM, which requires the programs to be link-edited in RMODE(24), Start of changeas a switch to AMODE(24) is made around the BSAM call.End of change The assembler source code includes the required RMODE(24) statement. Normally, EXCI client programs run AMODE(31),RMODE(ANY).
  2. Start of changeBecause of this, the assembler versions of these client programs are unsuitable for use as Language Environment® MAIN programs.End of change
  3. Start of changeSDFHEXCI and SDFHDLL1 are downwardly compatible with CICS TS 2.3 and CICS TS 2.2.End of change

The sample client programs show you how to code a simple MVS client application using the EXCI CALL interface and the EXEC CICS LINK command.

Each version of the client is divided into three separate sections as follows:

  1. The first section issues a single EXEC CICS LINK command to inquire on the state of the sample VSAM file, FILEA, in the target CICS system.

    If the file is in a suitable state, processing continues to sections two and three, which together provide complete examples of the use of the EXCI CALL interface.

  2. The second section initiates a specific MRO connection to the target CICS system and, once the pipe is open, performs a series of calls that each retrieve a single sequential record from the sample VSAM file, until no more records are available.
  3. The third section is a simple routine to close the target sample file once processing of the data is complete. It also terminates the MRO connection now that the link is no longer required.

Some of the parameters used on the EXCI CALL and EXEC CICS LINK commands in the client program need to be tailored for your own target CICS server region. Change these as required, then retranslate, compile (or assemble), and link-edit the program.

The variables and their values specified in the sample programs are given in Table 24.

Table 24. Parameters used in the sample client programs
Variable name in sample program Default value
TARGET_FILE FILEA
TARGET_TRANSID EXCI
TARGET_SYSTEM DBDCCICS (applid)
TARGET_PROGRAM DFH$AXCS
TARGET_USERID Defaults to batch region's user ID
APPLICATION BATCHCLI

The assembler versions of the client programs are supplied pregenerated in an executable form. All versions of the program accept two run-time parameters, as follows:

  1. The first (TARGET_SYSTEM) specifies the server region APPLID.

    For the pregenerated assembler versions this avoids you having to reassemble the programs to specify the applid of your own CICS server region. You can also use the sample client programs with different CICS regions without needing to modify the programs each time.

  2. The second specifies the user ID to be used on the call interface DPL_request.

You specify these positional parameters on the PARM statement, separated by a comma.

Using the COMMAREA in the sample programs

Data is passed between the sample client and server programs using a standard CICS communications area (COMMAREA) for passing data between programs. The definitions of this COMMAREA are identical on each side of the EXCI link to ensure that data is mapped correctly.

The sample client program DFH$AXCC minimizes data transmission by specifying a specific data length to avoid sending the whole COMMAREA over the link. The data length option specifies a binary value that is the length of a contiguous area of storage, from the start of the COMMAREA, to be passed to the server program. This is because the amount of data being passed to the server is small, but the COMMAREA itself is much larger so that the server can return the requested records from FILEA. Specifying a data length when the amount of data being passed is smaller than the COMMAREA improves performance.

Sample program DFH$ATXC passes the full COMMAREA to the server program because it makes changes to the file records and the whole of the changed record needs to be passed to the server.

The first and third sections of the sample client programs define the COMMAREA as only 18 bytes (no data is requested from the server in these sections). For the second section, the sample client program defines the COMMAREA as 98 bytes, the extra 80 bytes being required for the sample server program to return a record from FILEA. In all sections, the data length is defined as 18 bytes. The COMMAREA structure is defined in the sample programs as follows:

Bytes Data type Field description
0-3 Fullword Call type code.
4-11 Char(8) Target file name.
12-17 Char(6) Ridfield identifier.
18-97 Char(80) FILEA record data area.

Note that, although the COMMAREA structure is described in both the client and server programs, the actual size of the COMMAREA made available by CICS to the server is determined by the client program. If you modify the sample programs to work with one of your own application programs, make sure you specify a COMMAREA large enough to handle the maximum amount of data the server is expected to return to the client. The server must not attempt to return data that is larger than the COMMAREA specified by the client.

For more information about using a COMMAREA for passing data between CICS programs, see the CICS Application Programming Guide.

Installing the EXCI sample definitions

Resource definitions that support the EXCI sample programs are included in the CICS system definition file (CSD) in groups DFH$EXCI and DFH$FILA.

Note that the sample definitions, while included in the CSD, are not included in the IBM-defined group list DFHLIST. Thus, if CICS is initialized with GRPLIST=DFHLIST, you must install the EXCI resource definition groups before using the samples. Alternatively, you can add the sample groups to your startup group list, so that they are installed automatically at system initialization.

Start of changeTransactions that are to be linked to from the batch program need to specify the mirror program (DFHMIRS) as the program name in their transaction definitions.End of change

The resource definition groups that must be installed are as follows:

DFH$EXCI
This contains definitions for the sample server transaction, server program, EXCI connections, and sessions.

Only one server program is included--in assembler language, called DFH$AXCS.

The sample application is designed to run the transaction EXCI, which is defined to invoke the DFHMIRS mirror program and references profile DFHCICSA. The required transaction definition for EXCI is included in the group.

Sample CONNECTION and SESSIONS definitions for specific and generic connections are included.

Note:
Both the generic and specific connection definitions supplied in the sample group DFH$EXCI specify ATTACHSEC(IDENTIFY). This security option causes the server program DFH$EXCS to fail with an ATCY abend if you run the sample programs in an environment that does not have RACF®, or an equivalent external security manager (ESM), installed and active.

If you want to run the external CICS interface sample programs without any security active, you must alter the connection resource definitions to specify ATTACHSEC(LOCAL).

DFH$FILA
This contains the definition for the supplied sample VSAM file, FILEA, which is referenced by the EXCI sample programs.

Once these are installed, you must ensure that interregion communication (IRC) is open. If IRC is not opened during CICS initialization, set it open using the CEMT SET IRC OPEN command.

Running the EXCI sample applications

If you want to use the COBOL, PL/I, or C version of the EXCI client program, you must translate, compile, and link-edit the program into a suitable library.

You can use the sample JCL shown in Figure 22 as a basis for creating your own batch job to run the client program.

If you use the pregenerated assembler version, specify the APPLID of your target CICS server region as a parameter on the EXEC statement for the client program, as follows:

//*===============================================================*
//ASM       EXEC  PGM=DFH$AXCC,PARM='applid,userid' 

Where: applid is the applid of the CICS server region userid is the userid for the DPL_request call. Note: If you omit applid, you must keep the comma preceding the userid.

Change PGM=DFH$AXCC to PGM=DFH$ATXC to run the other client sample program.

Results of running the EXCI sample applications

An example of the output produced by successful execution of the pregenerated assembler version of the client program, DFH$AXCC, is shown in Figure 23.

If an error occurs while running the application, then, assuming the error is not severe, messages are written to the SYSPRINT output log displaying the reasons and/or return codes that cause processing to be aborted. Several examples of error-invoked output are shown in Figure 24, Figure 25, and Figure 26.

An example of the output produced by a successful execution of the pregenerated assembler version of the client program DFH$ATXC is shown in Figure 27. If an error occurs while running the application, errors are produced as for DFH$AXCC.

After running DFH$ATXC, program DFH$AXCC should be re-run. The output should be as shown in Figure 28. The changes up to and including records with RIDFLD values of 500000 were committed using an SRRCMIT call to tell RRS to tell CICS to perform commit processing. Later changes were backed out by issuing an SRRBACK call. This caused RRS to tell CICS to perform a ROLLBACK of these changes.

Clearly, FILEA is changed as a result of running DFH$ATXC. It should be restored to its original state by running the LOADFILE step of DFHDEFDS.
