Hi gurus,
JOB1 run daily and it create a GDG verion daily. We need to write JCl which will merge all the version created in the particular month. This job will run at the end of the month.
How this can be achieved .
TIA

ranjit5311,
Just give the base of GDG as input and code disp=(old,delete,keep). By doing so the daily base will have versions starting over from 1 after the monthly job.
According, to the soltuion above, If we run the JOB at the end of month feb then it will merge gdg vertion from JAN to Feb. But I want just the version of the feb month.
TIA

ranjit5311,
Look carefully on the DISP parameter on this input GDG. I am Deleting all the versions which is explained clearly in my post.
according to his query he asked you to keep only last month backup...
if you look into jcl , jcl disposition refers to DISP=(OLD,DELETE,KEEP)..means you are deleting the existing version if it runs successfully if it not it keeps that dataset..
could you please explain me. in the JCL $$DD01 referring to first DD then what about the second DD... it automatically refers to the second DD?
one more doubt on KEEP, what is difference between KEEP and UNCATALOG..what is differences between PASS. _________________ Thanks&Regards
