Way to include file tailoring output in next step of JCL

Hi,

Is there any way to include file tailoring output in next step of jcl. My file tailoring output will only be having files names as below.

//DD1 DD DSN=DSN1,DISP=SHR
//DD2 DD DSN=DSN2,DISP=SHR
//DD3 DD DSN=DSN3,DISP=SHR
.
.
//DDX DD DSN=DSNX,DISP=SHR

There all are database related files used to run my application program. It should present in my run program step.

As you can not modify an active JCL, then the answer is NO

Can you please let me know what is the modification I need to do in JCL?

The easiest thing to do is submit a second job from the first.

I cant submit because I need to have all these files names in the second step.

I am purposely using skeleton to have those files depends on some conditon. It is not a JCL. the file tailoring output wll having only the files names to run the program.

Hello,

You have a solution in search of a requirement. . . For whatever reason you chose file tailoring. That is not the only way to create/modify jcl.

Many of us have created jcl "depending on some condition" and submitted it via the internal reader. So far, i see no reason that you cannot do the same. Instead of a second step, you would have a second job. . .

Possibly you can explain the file tailoring requirement? Or why the alternative won't work for you.

Can you show us what your 'next step JCL' is supposed to look like, if you could build it?

Thanks for the Help. I am doing by below way.

// JCLLIB ORDER=XXXX.SKELETON.OUTPUT'
//STEP1 EXEC PGM=IKJEFT01..
//.......
//.....
//STEP2 EXEC PGM=XXXXX,PARM=&RRRRR
// INCLUDE MEMBER=DDDDDD
//STEPLIB DD DSN=HLQLOAD,DISP=SHR
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*

DDDDDD will be my file tailoring ouput. which will be having file names as below.

//DD1 DD DSN=DSN1,DISP=SHR
//DD2 DD DSN=DSN2,DISP=SHR
//DD3 DD DSN=DSN3,DISP=SHR
.
.
//DDX DD DSN=DSNX,DISP=SHR

Instead of writing it to physical files is it possible to use temp files?

You can use IKJEFT01 in the next step and invoke a Rexx program to parse the output , the allocations and then call the program you were going to call. Of course, if you are going to do this, there is no reason to use file tailoring since you can probably call the step2 program directly in step 1.

If you think you must do it using JCL (and there are reasons that may be true) then as others have sayd, no, you can't dynamically change JCL while the job is running

Hello,

If you are using JCLLIB...

Use file tailoring to get your tailored list of datasets, and also include the static part of your job step and also formatted as a PROC . Put this into the JCLLIB dataset.

In the second step, refer to the newlib created PROC JCL.

Hi Pedro,

I maybe misunderstanding what you are saying, but how do you get STEP2 to refer to a PROC created in previous step.

I am not sure it is possible to do.

I am not sure how much checking is done ahead of time, but I think they are just member names. Create a new member in one step and refer to it in another step. If that is not possible, then submit another job, as has been recommended several times.

Hi Pedro,

PROCS are expanded at soon as the job hits JES2.

Hello Jeyaseelan,

Do you have something running yet?

If not, i recommend you go ahead and generate all of the jcl needed for the 2nd process and submit via the internal reader.

How does your current first step know which dd statements to use?

Thanks for all you replies. Dick can you please send me the piece of code to write the skeleton output to temp files?
