Introduction:


DFSORT is one of the IBM Data Facility family products and is a high-performance data arranger developed by IBM for OS/390 and MVS/ESA users. The whole data set is affected, for most of the processing done by DFSORT. The term record refers to a collection of related information used as a unit (Field).

DFSORT is purely mainframe related utility which is used to process or manipulate Sequential files with the help of JCL or other mainframe utilities which can run IEBGENER in background.


Audiences:


Readers who are having or not having mainframe knowledge.


Objective:


The tutorial is intended for the readers with a little mainframe experience as the tutorial mainly focuses on how it is used in mainframe environment. In the tutorial, all the topics are covered with in depth description and can understandable by anyone who had minimum computation background.


Prerequisites:


Need to have the JCL knowledge if learning the DFSORT for mostly processing Sequential files. Learn JCL tutorial at JCL Tutorial here if required.

Having the computation background will be an advantage in understanding the concepts a bit easy. Without having computation background, it is a bit time taking to understand the concepts and need to go through the topic more than once to understand clearly.
