Hi
MIPS topic again:
One of our customer has reported that our (long runing) server
application is using 500 MIPS /day.
How to understand this, and is there any standard tool to generate a
report like this(i.e how many MIPS has used )

This particular kind of thing is sometimes seen where a program is
NON-LE compliant and gets called by LE compliant code. R12 is not what
LE want's it to be (and x'000c' is NOT what LE wants) and so it
augers in and makes a crater.

Unfortunately, not all of the CPU consumed by a task is collected.

Not really. A disk failure - two disk failures actually - on an Array Group
of 3390-3 can affect over 300 volumes. I would much rather manage restoring
4-10 large volumes than 300+ small ones.

SYSLIB statements must come before LNKLST entries. Much simpler IMO to
create a separate PROGxx member with just the SYSLIB statement(s).
Lot of sysprogs like to throw everything into one PROGxx member but I find it
easier and clearer to separate them. For example, PROGxA for APF
