Doesn't answer your Q. However, unless you have a very I/O intensive workload
e.g. TPF system, normally there is sufficient SAP capacity for Z servers. The
other point to note is SAPs on z14 servers also support SMT (Simultaneous
Threading) as standard..

Is SMT a good thing for a SAP invocation?
Speaking of z14 servers, would you consider the default number of SAPs on a ZR1
sufficient most of the time?
What do you consider "very I/O intensive"?

Quite different. The sell the security as part of the OS. They don’t then bash
the security (their own product) and try to sell you additional products.
IBM actually tells you how great mainframe security is and use it as a selling

IREXCOM has no interface for reporting that a variable has been dropped. All
that it can do is to return the variables that are still known. The statement
foo. = 'Blanket' does not create any variable other than foo., even though
