What is RESTART? How is it invoked?

Answer Posted / devang

The restart parameter is usually referred as RD(restart
definition) in JCL.

I can be coded on any job steps with conditions like
RD=RNC(restart with no check point)
RD=R(restart)
RD=NC (no checkpoint)etc

Stratigically placing of RD parameters is a task which
requires extensive analysis of the JCL flow.
