Answer :

STEPS BEFORE MERGING?
DUMMY DATASET USES?
DIFFERENCES BETWEEN IDCAMS AND ICETOOLS?
DIFFERENCE BETWEEN ALL JCL UTILITY TOOLS?

Dummy dataset manner it dont have any manipulate fields. So,we region a dummy

Answer :

A PDS or Partitioned Data Set is a dataset containing more than one contributors, every of which holds a separate sub-information set, similar to a directory in other styles of report structures.

This type of dataset is regularly used to keep executable programs (load modules), supply application libraries (mainly Assembler macro definitions). A PDS is most incredibly analogous to a Zip record on microcomputers, besides the documents stored in a PDS aren't compressed.

The Partitioned Data Set can only allocate on a unmarried extent with the maximum size of 65536 tracks.

Besides participants, a PDS is composed also of their listing.

Each member may be accessed directly using the directory structure. Once a member is positioned, the statistics saved in that member is dealt with in the equal way as a PS (sequential) records set.
