What are the differences between JES2 & JES3 ?

Answer Posted / bala

JES3 = Job Entry Subsystem 3

An MVS subsystem that receives jobs into the
system,converts them to internal format, selects them for
execution, processes their output, and purges them from the
system. In complexes that have several loosely coupled
processing units, the JES3 program manages processors so
that the global processor exercises centralized control
over the local processors and distributes jobs to them via
a common job queue.


JES2 = Job Entry Subsystem 2

An MVS subsystem that receives jobs into the system,
converts them to internal format, selects them for
execution, processes their output, and purges them from the
system. In an installation with more than one processor,
each processor's JES2 subsystem independently controls job
input, scheduling, and output processing.
