Hi,

I have seen one of my production job it has 5 steps.At step3 there are using the gdg as input GT.C00T.KBY.DOCUTEXT.DATASET.XREF(+1),DISP=OLD/DISP=SHR.This GDG is not created any where in the current job.As I know if we code the GDD like GT.C00T.KBY.DOCUTEXT.DATASET.XREF(+1),DISP=SHR this should be created in the prior steps of the current job.

Can u please any body let me know what is the meaning of it.

yrcreddy,

Are you sure that they are not creating the GDG in the first 2 steps? Your Job will fail with a JCL error if you try with +1 gen

yrcreddy,

Read my post carefully once again. If the GDG is not created in the same job and if you are refering the +1 generation your job will ABEND.

Hi yrcreddy,
Is the job using procs or includes? If so are you looking at the jcl listing that is produced when the job runs? That will tell you all of the files that were used.

May be it is created in one of the programs you are executing step1 and 2 of your JCL.

Hi hchinnam,

You mean to say the dataset is getting created dynamically.

if that is true there should be a DDNAME for that Dynamically created file,

In our shop we have a utility callled MBALLOC which will be used for dynamically creating a file.

For that we have to give the DDNAME SYSALLOC

HI reddy please check in your JCL any extra DDNAME is present.If you have one Browse the file associated with the DDNAME you will find the file name that is dynamically created.

Correct me if i am wrong

dynamically creating gdg's is not alot of fun, I doubt if that is the problem.

I believe jyoung, has hit upon the solution (actually the problem).

gotta look at them jes outputs; viewing JCL in edit or view just does not allow for proper interpretation. I often use TYPRUN=SCAN if I have a question on how the JCL expands.

I have no idea what yrcreddy meant by this:
