I’m not really claiming to troubleshoot this but I wonder - based on your
EXCP count comment - what JVM heap specification people (you) are running
with. I wonder if it’s garbage collecting to death.
I'm no expert of z/OS Java garbage collection but I'm wondering how it
can cause high EXCPs?
I suspect it's opening all the zFS files required for WLP.
(I’d also observe Liberty Profile has a generally good reputation for being
lightweight and swift to start. As always, and z/OSMF Development forgive
me for this comment :-) , it depends on what you run in the JVM.)
That's my experience. But we have a zIIP.

On our z14, z/OSMF takes some 60m+ EXCPs and 300 seconds of CPU time
(according to SDSF) before it can even be used...
(and anything that announces its availability with "...ready to run a
smarter planet" just makes me cringe.)
Carmen's remark about 'clear documentation' is very much on point. Like
him, I've been battling with the Configuration Assistant in order to
create
a comms policy.
Every time I find any documentation that might help me, the examples
given
show a z/OSMF UI that is different to mine and so the confusion starts
right at the point of logging on.
I suppose its because z/OSMF is still a very young bit of software and so
changes between versions are much more visible.
The idea that z/OSMF is intended to eventually replace SMP is quite
depressing, but - disclosure - I remember I had similar difficulty taking
SMP on board some aeons ago... using it is almost second nature now.

No zIIP here either. I guess, it doesn't matter. I expect 1 more
migration, 2.1 to 2.2. Then mothballing

I thought my situation was bad - it only takes 30 minutes at 100% CPU
on
my
test system to bring up z/OSMF.
Does anyone run this on a production system?
