It takes z/OSMF about an hour to fully initialize on my ZD&T … same behavior
(lots of SIOs and CPU) IBM says its fixing this but its been quite a while. Its
Java related.
And how much does ZD&T cost? We had customer complain that our Apache
Tomcat server was taking 15 minutes to start on one LPAR and 15 seconds
on another. Turns out the didn't have a ZIIP enabled
on the first LPAR. Java is not viable on z/OS without zIIP engines.

Im using z/OSMF on my little zPDT system, and it is doing about 50,000 SIO
a second,
when it is doing "nothing"
How canI tell what it is doing? I expect most of these files are in the
zFS file system, but I dont know the best way of finding out what is going
on.
I do not have tools like Strobe or APA,and I am familiar with dumps etc
