You work for big shops. Majority of mainframe users is not sysplexed.
Probably almost every shop, even monplex use more than one systems
(that's why we have LPARs). Probably many of them have NJE
established, I don't know how many (*), nevermind.
The question is how many of them use NJE to submit the jobs on
regular basis.
(*) However I wonder if NJE is so popular for "everyday", "regular"
use. Once upon a time I studied NJE RACF security, asked questions
to RACF-L group. Limited number or answers indicated it's not very
popular.
BTW: Here, in Poland, we have approx. 100 mainframe sites, and 140
CPCs.
Only 4 (four) of them have production sysplexed. As numbers above
show, many of them have one CPC. As far as I know, vast majority of
them do not use NJE, even do not have NJE configured. Whole job's
lifecycle is on same system.
About 20 years ago we had approximately 75 systems connected up via
NJE (SNA & Bisync). These were *SEPARATE* companies (not connected by
anything but a telco wire . The company I worked for had 2 sites
(Chicago & NY) were connected up VIA NJE and there were thousands of
jobs submitted on one system and sent to the other site everyday for
execution.
We were a small-medium company yet had many connections across the US
(mostly NY & west coast) .
