Thank you for your consideration, Tim.
I need the way for collecting performance data of Linux at z/VM side.
And it'll be better if I could save the data from z/VM to mysql or
files on the other Linux server.
Is it possible to read and get the files from CMS using cmsfs driver

You need to address 3 problems using "native tools" (or any tools for that

Hi,

Little wary of doing so. A "fix" would probably break our /etc/fstab

Absolutely agree with that!
There is also what I consider a bug in SLES 9 - if the address ends in a
A-F as opposed to a 0-9, the "p" is left off. We've coded around it
where needed. (See 900A-900F below).

Mary Anne,
You'd think dump space would be related to storage in use but we have a
minor problem in VM5.2 where not using our central storage frequently
enough causes CP to allocate larger dump areas. Maybe it'll improve in
VM 5.3.
Back in 2006 IBM support told us-

Ah, thanks John. One has 73485, the other 468941. I guess it allocates dump
space based on, usage or something? Setting dump off shows a spool usage of
1%.
