I have never worked in a single system shop,
either before or after SYSPLEX, so I have
always been in an environment where the job
could be handled in three different places.
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.
BTW, the results are not indeterminate.
If you use a symbol in the JCL, you will
always get a JCL error.
That's because it is forbidden by IBM. I'd prefer "determinate on single
system *only*". Limited functionality. This is more than I have today.
Today I have nothing.
