Is JES3 really considered by all to be better than JES2 ??
I know it was 20 years ago, but JES3 gave me nightmares, whereas JES2 never has.
From an application point of view.
The announcement mentions a few of the JES3 functions that have been
recently added to JES2, as well as one of the new capabilities being
added in z/OS 2.4, as justification for the decision to finally sunset JES3:
"JES2 has added functionality, including dependent job control, deadline
scheduling, 8-character job classes, and interpreting JES3 JECL control
statements. For z/OS V2.4, additional function to aid in migrations is
planned, including Disk Reader capability and enhanced JES3 JECL support
in JES2 (ROUTE XEQ). Today, as a result of our strategic investment and
ongoing commitment to JES2, as well as continuing to enhance JES3 to
JES2 migration aids, IBM is announcing that the release following z/OS
V2.4 is planned to be the last release of z/OS that will include JES3 as
a feature."
They have actually done considerably more than what is listed in the
SOD. There is still more to do, but as I said they have until September
2023 to get it all done...
