CICS Program & JCL - Failure

Postby aamirhirani » Sat Jan 14, 2012 12:11 am

Hello,

I am trying to run a CICS program but am not sure whether the JCL being created is of the CICS program or not. Secondly what is DFHRPL for and how can one install that in CICS? Lastly, I had assigned a DSN to Loadlib 'USER.CICSAOR1.LOADLIB' in my JCL as this was not present but on submitting the JCL it did not work.

I have created a program and transation in CICS and on running the transaction I get a message 'Transaction cannot run because program is not available.'

My Program and JCL are below

1. CICS programs are NOT run through JCL. They run under the control of CICS. The program needs to be compiled into a load library that is concatenated into the DFHPRL for the CICS region your program will run in. DFHRPL is merely a special DD name used by CICS to indicate where to load programs from.

2. Depending upon how the region is set up, you may need to define the transaction and program (and files, if any) to CICS before you can execute your program. These days, CICS transaction CEDA is used to define programs and transactions.

3. JCL to execute CICS will start something like this:
//CICS220  EXEC PGM=DFHSIP,                                             00320029
//         REGION=&REG,                                                 00330029
//         TIME=1440,                                                   00340029
//         PARM='START=&START,SYSIN'                                    00350029
//*                                                                     00360000
//********************************************************************* 00370000
//*        THE CICS STEPLIB CONCATENATION                               00380000
//********************************************************************* 00390000
//STEPLIB  DD   DISP=SHR,DSN=&INDEX1..PROD.SDFHAUTH                     00400061
//*TEPLIB  DD   DISP=SHR,DSN=&INDEX1..CICS.SDFHAUTH                     00400061
//         DD   DISP=SHR,DSN=SYS5.MAINVIEW.V505.BBLINK                  00420029
//         DD   DISP=SHR,DSN=CEE.SCEERUN                                00430044
//********************************************************************* 00440000
//*    THE CICS RELOCATABLE PROGRAM LIBRARY (DFHRPL) CONCATENATION      00450000
//********************************************************************* 00460000
//*                                                                     00500036
//DFHRPL   DD   DISP=SHR,DSN=CICS.JPUE.R242.CICS.LOADLIB                00620061
//*        DD   DISP=SHR,DSN=&INDEX1..OS390.V210.UPGRADE.SDFHLOAD       00620061
//         DD   DISP=SHR,DSN=&INDEX1..PROD.SDFHLOAD                     00620061
//*        DD   DISP=SHR,DSN=&INDEX1..CICS.SDFHLOAD                     00620061
//         DD   DISP=SHR,DSN=TCPIP.SEZATCP
but there will be plenty of other DD names -- usually dump data sets, intrapartition definition, extrapartition data sets, along with other internal files used by CICS.

Hello and welcome to the forum,

Suggest you talk with whoever gave you the assignment to write this cics program. They should be able to tell you in which cics region you should compile, link, and run your program. Most often someone writing their first cics program will not have the security permissions to create their own cics region. . .

Later, this may be part of the learning, but i would not think for the very first coding attempt.
Hope this helps,
d.sch.
