Script Params/CSV Read Issue in Win -> Linux Remote Test
Hello!
I'm trying to set up remote servers to deliver load to any one of several
middle tier applications that do XML-RPC soap-ish things.
I'm using the same JRE/JDK (1.5 series) and have tried running my tests with
both the 2.2 and 2.3RC4 versions of JMeter. (No mixed versions going client
to server...) The controller machine is running XPSP2 and the windows based
server machine is also running XPSP2. My Linux server machine is running the
latest stable Ubuntu LAMP release.
I've got a few tests which work as expected going from Win -> Win or just
locally on my Windows laptop. My linux jMeter servers accept requests and
are running the tests and are picking up the text file used for storing test
inputs. From there, things get odd.
While the Linux machine appears to be accepting/pulling data from the CSV,
it only uses the first line from the file and only for the first sampler in
the thread group. I have converted the input file to unix style carriage
returns (on the server side only), which doesn't seem to cause any
improvement.
Any thoughts?
Thanks,
Sean Slattery

It only needs write access for the log files, and you don't have to
start JMeter in the bin directory. So you should just be able to run
it from a directory in which you have write privs.

I might be having an issue with the distro or unpack location and executing
user. I'm using Ubuntu LAMP Server, rather than any of the desktop distros;
and I was messy, and unpacked everything (as root) in the root directory,
like I do in Windows.
Since doing anything to files in the root directory requires root
privileges, jMeter didn't have sufficient rights to write in its own
directories.
In the future, I should probably unpack into /usr/ or /usr/bin/ which may
avoid much of the headscratching I've just done. This install is a prelude
to doing something much more cool and fun with jMeter (dedicated bigger
iron), so some experimentation is called for...

Mostly what the doctor ordered. Running the test only locally on the linux
machine revealed a few issues which were otherwise obfuscated:
- The permissions for the directories/files/all that were set so
that jmeter couldn't write logs or anything else. I suspect that
this was causing several other problems.
- jMeter couldn't actually find the csv file where my data is stored.
What I specified and what was saved in the jmx were different things.
I specified ./../tests/TestData/DataFile.csv
jMeter saved this as /TestData/DataFile.csv
My solution for the permissions was brute force and probably poor form:
sudo chmod 7777 /jakarta_jmeter/ -R
On the other hand it works. (An RTFM for how to properly set the permissions
for jMeter to be run by a regular user would be appreciated...)
For the other problem, a minute or so in nano on the linux box and syn in
windows did the trick.
The result is that I my tests run correctly now.
Thanks!

No, I mean try running JMeter in non-GUI mode - not as a server.

There is no client.

There is no separate controller.

Oh, you mean there a different way to start the server? What would the
switches be for that? Does that change how the client/controller can view
the test results? Does it mean no Windows GUI on the controller?

Pesky shift key... Um, yah, like that, using a lowercase s for the switch.
Thanks again!

Server mode does not require a GUI, but is not the same as non-GUI mode.

Thanks for your reply.
I should have mentioned that I've built the server without a GUI, will
primarily be using SSH to enter the system remotely.
I've started rmiregistry and jMeter (jmeter -S) both separately and using
the jmeter-server shell script. I've also done most startup variations which
use "nohup" and "&". The data file does exist in the directory where the
script should expect it (%jMeter_home%/tests/TestData/) on the linux box as
well as the windows control box.
Perhaps try running the test in non-GUI mode on Linux, in case there
is some interaction with RMI. I think it's unlikely, but it's easy to
test.

Perhaps try running the test in non-GUI mode on Linux, in case there
is some interaction with RMI. I think it's unlikely, but it's easy to
test.
