Thank you Emilio.
In my load tests etc I will possibly try to measure and share some stats
later with the list in future.
I understand zenloadbalancer being a small community and I am willing to
compile it myself and built it in s390 platform SuSE Linux. I will need
some direction from someone experienced in the project. Hopefully
someone can help. I don't want to be aggressive in it, but I want to
start it when someone is ready to give me some directions.
First thing I would need to acquire is list and versions of all the
sources used to built it. A lot of them I can directly copy-PERL code
etc from ISO image. I would need the sources for the binaries found in
the ISO. Hopefully original sources were not modified except the install
locations-someone may confirm/help me. Also, someone may give me basic
steps if possible so I could do similar to the current ISO build
process. I would not want to code the installer-of course I cannot make
the installation program as nice and simple as it is in Intel platform
ISO today- because I am not experienced in creating a distribution.
Later, if I am successful, I plan to share the detailed steps with the
community.
Lastly, I want to state that I am not a developer, I am a system admin
so hopefully I can still do it unless, it needs heavy coding.
I feel this product/setup can be very useful for the mainframe Linux
community if we can port it.

Subject: zenloadbalancer port to Linux on Mainframe S390 platform under
z/VM
First of all Zenloadbalancer is a wonderful product, nicely implemented
using already existing tools like pen, pound, mini_httpd, ucarp,
check_http, rsync etc. Nicely written lightweight GUI. Running with RAM
usage of 70MB-impressive! I am very pleased with its reliability, I
have just tested it until now for TCP loadbalancing, it's not in
production yet.
I wish I could keep it running in VMware environment but we need to run
it in our mainframe Linux (zLinux under z/VM) -we use Novell's SLES
(SuSE Linux Enterprise Server).
So my question would be- how could this be ported to s390 platform?
Since this is opensource and each of the tools can support s390 linux,
how could I run it on my small little SLES instance in the mainframe.
Most of the code is written in Perl. But there are some binaries
too.(see ELF binaries below). Are there any procedures I could follow to
do this myself if possible?
There is not procedure to do it
Also, any reason why the virtual appliance is based on 32 bit
version and the physical one is instead 64bit.-we use only 64 bit Linux
on our mainframe.
not yet 64 bits support .
My wish list:
1) Port to other Linux platform like S390(mainframe)-CentOS/RHEL
etc
2) command line support /documentation for regular LB activities
etc (because the GUI is a little slow-its works perfectly fine, please
don't get me wrong)
3) some documentation/specifications listing requirement for
sizing purposes listing traffic/data/CPU/memory/workload sizing limits
etc.
Good wish, we accept help of other members to do this and other wishes,
the help is welcomed.

Thank you for keeping it open source!!
It's difficult to maintenance an open source project:
give support
solve bugs
new features
web content
documentatcion
a long etc..
Always we accept any help in work that the community could give us and
we are open to hear proposals!
