The best option is to use SNMP. Configure and run the netsnmp or ucdsnmp
packages and have an agent collect the appropriate MIBs. ESALPS does this very
well. This option will also be the same for 2.4 or 2.6.
I had used the XASTOR package (I think available on the VM download site) and
created a

Any user with normal class 'G' user can do this easily
using ESALPS. Or any browser can do this as well.
(ESALPS uses SNMP as it's data source, thanks Tom)

Hi, folks.
I need to be able to follow the running task structure of a Linux guest
from outside the virtual machine that hosts the Linux guest. I want to
be able, from a CMS guest with class E privs, discover what Linux is
running and how much resources the processes are taking.
Anybody got a clue,
Right...but who does it?
Meaning, when I issue a Flashcopy command (is it a command?)
For proper flashing, Linux has to respond and "sync" the buffers
and NOT do anything until told the flash was done, plus Oracle has to
pick up on this fact, and prep itself for the flash. Then, I would
assume,
sync flushes filesystem buffers.

The question was, does Linux and Oracle understand Flashcopy or in your
case snapshot.
The DDR backup is just first cut recovery.
TSM backup is second but these in our case were done with the Oracle
database down.
As far as table reloads go our Oracle support unit handles them.
I'm not sure what their scheme is. They may have other backups in addition
to TSM.

Apparently we are going to be moving a large set of resources to the
mainframe, and will be moving the data to Oracle 10g (note..64 bit).
The last time I ran Oracle on the mainframe was Oracle 6, under VM/ESA

there).
