What command did you use to determine that you had 768m central storage?
QUERY STOREAGE?

All of this with 8gig? It's certainly doable but I wouldn't recommend
it. Do you have any XSTORE (extended storage) defined? Issue a QUERY
XSTORE command if you don't know. I'd say you might have some paging
issues.

Hello Dave,
In either case, if a linux (zlinux or intel) gets 768M it will
eventually allocate all storage it can get. If not for applications it
will use the 'free' memory for datacache. So in that repect, yes, the
linux will use the storage you assign to the guest. But as for if the

What other virtual machines do you have running along with this z/OS virtual

Hi all,
Today, for the first time ever, I had a z/OS go into z/VM's ELIGIBLE list. The
z/OS stopped completely and the console was unresponsive. My questions is:
how did it get there and how do I query z/VM to see what it is supposedly
waiting for?

It depends.
The cpu power of a z9 (or now z10) is larger than a z9BC.You need to
consider what 'size' IFL's you're talking about, what kind of
applications- do they do a lot of I/O use cpu, use memory, etc.
From: The IBM z/VM Operating System [mailto:[EMAIL PROTE
You can use SET SHARE to stop the CPU runaways.
We have one bad app server we decided to cap permanently.
The application code problems have actully been on a Windows server -but
it impacts the oracle db on the mainframe- we just capped the test db
server so it doesn't impact the other servers.

I believe the PIPESERV package from the IBM VM Downloads website contains
a
SYSRECS REXX stage that will collect accounting cards. PIPESERV is a tool
for creating a service vitual machine, like DISKACNT and this stage seems
just right for being the primary task for PIPESERV to run there.

The ACCOUNT command is part of the CUF and does a simplified report on a
subset of the accounting records. The RETRIEVE command does the actual
movement of accounting data to disk.
