⟩ WHAT IS DIFFEENCE BETWEEN PDS AND PDES?STEPS BEFORE MERGING?DUMMY DATASET USES?DIFFERENCES BETWEEN IDCAMS AND ICETOOLS?DIFFERENCE BETWEEN ALL JCL UTILITY TOOLS?
dummy dataset means it dont have any control fields. so,we
place a dummy
ex:SYSIN DD DUMMY(NO FUNCTION).
JCL UTILITY TOOLS:
IEBGENER UTILITY:
IT IS USED TO CREATE,COPY OR PRINT SEQUENTIAL DATASETS.
IEBCOPY UTILITY:
I IS USED TO COPY NUMBERS OF PARTITIONED DATASETS.
IEFBR14 UTILITY:
THIS UTILITY IS CALLED DUMMY UTILITY ALSO BY USING THIS
UTILITY WE CAN CREATE A DATASET.
