More than one instance of GTF in an MVS image was new in z/OS 1.6.
I'm a little curious about this one.
I was told (over 20 years ago) that, due to architectural constraints, only one
instance of the monitor instruction could run.
I had a few times (same era -- I haven't been involved with GTF in over 15
years) where I could have run two (or more) traces and solved problems in
parallel rather than sequentially.
As implemented right now in z/OS, PER is system wide and not changed
when address space switching occurs (though that should be technically
feasible). But, what's to stop multiple GTFs in z/OS 1.6 and higher from
processing a single PER event?
