How to refer the GDG generations If the step restarted

There are 10 steps in my job. The job abended at step6. I created some generations before step6. If I restart the job at step6 then how should I refer to those GDG generations?

Hi Ramana,

It depends on how many generations you created in the orig run:

If you created 3:

You created the 1st w/dsn=dsn1(+1), use dsn=dsn1(-2) on restart.
You created the 2nd w/dsn=dsn1(+2), use dsn=dsn1(-1) on restart.
You created the 3rd w/dsn=dsn1(+3), use dsn=dsn1(0) on restart.

If you created 2:

You created the 1st w/dsn=dsn1(+1), use dsn=dsn1(-1) on restart.
You created the 2nd w/dsn=dsn1(+1), use dsn=dsn1(0) on restart.

The thing is GDG won't be cateloged until the end of job successfully.
If the job isn't completed successfully then the gdg won't be catelog successfully.

I agree with rohit.

It also depends on the dispositions used in the previous steps.

Thanks

Rohit-Y,

The datasets CAN be cataloged even if the job abends, provided that the job abends AFTER the the step that created the GDG dataset completes SUCCESSFULLY and the DISP was coded appropriately.

hi ,
in this case i think there is no need to use restart to step 6 to create new , because new generation always starts with (+1)
this is how u r jcl look like
//job
//step1 dd dsn abcd.gdg(+1), disp(,catlg)
//step2 dd dsn abcd.gdg(+2), disp(,catlg)
//step3 dd dsn abcd.gdg(+3), disp(,catlg)
//step4 dd dsn abcd.gdg(+4), disp(,catlg)
//step5 dd dsn abcd.gdg(+5), disp(,catlg)
//step6 dd dsn abcd.gdg(+6), disp(,catlg)
//step7 dd dsn abcd.gdg(+7), disp(,catlg)
//step8 dd dsn abcd.gdg(+8), disp(,catlg)
//step9 dd dsn abcd.gdg(+9), disp(,catlg)
//step10 dd dsn abcd.gdg(+10), disp(,catlg)

in this case let us say u r job abends at 6
u will have the following generations

abcd.gdg.g0000v00
abcd.gdg.g0001v00
abcd.gdg.g0002v00
abcd.gdg.g0003v00
abcd.gdg.g0004v00

if u want to create generation 5 then u have to again start with (+1) ,but if u start the step in 6 u will get (+6) which will not give u correct result

correct me if i am wrong

thanks
