Hi Rodger,

Thanks for your answer. Could you please tell me How many Application Server do

We've had excellent performance with 4 GB and larger JVMs; our experience
with the 1.5 JVM in WAS 6.1 is that you can get excellent performance with
large memory allocations.  Note, though, that can be dependent on the
application.

I would be more concerned about the large session sizes - if you're using
clustering between guests you'll quite likely see high CPU use serialising
sessions that large.

I seem to have run into space problems uploading these, as well as a couple 
others.  That's been taken care of now.  All the presentations check out when I 
download them and compare them to the originals (including the ones Dick Waite 
said don't display anything).

PROP will read a maximum of 960 bytes, what it believes is 12 80-character
lines.

There is an old PROP APAR VM48600 from 1992 that fixes this problem for CP
output (class 3, 6, 7).  Dunno why it wasn't fixed for VMCONIO.

And I don't know if anyone has opened a PMR.

Re: Prop concatenating lines

[CHAPLIN, JAMES (CTR)]

Good afternoon Jan,
We use Tivoli monitor which works good (but not great), and we also
wanted to have a second method, so I looked at PROPs with much
disappointment. However we did come up with capturing exception messages
from Perfkit and send the information to our operational center.

You need to have Perfkit installed on your VM system. We focused on
capturing high DASD I/O and high CPU usage on our zLinux servers. We
wrote a separate set of scripts on each Linux server, not using PERFKIT,
to check swapping and memory (using crontab). But memory and swapping
may also be done through PERFKIT, I just did not explore that option
yet.

This involved setting limits in FCONX $PROFILE on PERFSVM, and then
creating a REXX (JSEND) to pass the message from VM to a Linux guest,
which in turn passed the message to our operators in our situation room
to notify us of any problems.

I can send you detail information on the simple code we wrote to your
email address off the list if you would like. Drop me a request to my
personal email, jhchap...@comcast.net, and I will pass you that
information.

Re: Prop concatenating lines

[Bruce Hayden]

With PROP, it seems, you can't.  I tried to write some automation
using PROP about a year ago, and couldn't get it to work.  Linux may
write multiple lines on the console with a single I/O, separating each
line with a newline character.  CP writes the output on the console as
separate lines.  But, if you also send the output to a secondary user
and use *MSG to read it (as PROP does), CP does not split up the lines
- you get one line per I/O with embedded newlines.  PROP seems to have
a limit on how long of a line it will scan for a matching message.  I
just looked to see if this was documented, but I didn't find it.

My alternative for that particular application was to write a CMS
Pipeline to separate the lines and look for the string.  Commercial
automated operations products should work as well.

AFAIK, GDDM-REXX is an optional feature of the GDDM/VM base priced
product. And the various pointers say this documentation is shipped
with the product materials.

According to IBMLINK, the publication can be ordered for $0.68 (plus taxes) :-)

Re: WebSphere Application Server for zLinux

Probably a bad idea I think, the garbage collector will take a long time and 
might have an
impact on response times.
I'm not an expert on this but what I hear from others here is far from 10 GB, 
more like 500MB-1GB
but I don't know any details abouth their applications.

Thanks a lot for your answers. Our applications have a big session data size

a big JVM heap size. Could we have a heap size of 10 GB using 64 bits?
