I will make the same comment I made last time this topic came up -
avoiding garbage collection is not usually a wise goal.
It depends on the workload(s). The point I made is that with the z13 and
z13s you have more such options, when/as they make sense.
To pick an example, I recall dealing with a Java workload that had an
unresolved memory leak.
Memory leaks are not a usual case, but I would suggest you will still
want to garbage collect.
I'm not arguing against large memory - I am all in favour of as much as
you can afford. It's just the suggestion that avoiding Java GC is a good
idea.
I believe that Java is one of the keys to the future of z/OS.
Suggestions like "allocate enough memory that you don't have to GC"
contribute to the view that Java is a memory hog and performs poorly.
That is damaging to Java on z/OS and as a result damaging to z/OS as a
whole.
