Sorry, too excited, "right" not "write"
Thanks again

You are write. The http_sessions directory was automatically removed
after reboot. I recreated this temp directory, and every thing worked
well. Thanks very much!

My guess was that you have not created the "/tmp/http_sessions"
directory. Note that the "successfully logged in" message is shown
even if the login fails. You must see the user home page if the login
is really successful (i.e., create event, logout, … must be visible).
The login failure message is also generated when the quality of
service is not good and SOME users fail to login. However, in your
case ALL login attempts fail which does not look like a QoS problem.
25 concurrent users is too small to saturate the system. You should
be able to get good QoS (no failure) for ~750 users per core on a
typical system.

As you pointed out , i found "UIDriverAgent[0].6.doLogin: Found
login prompt at index 1969, Login as csdjs16jl6, 707 failed." in the
run log. However, when i enter "csdjs16jl6" and "707" in the
browser, the application returns "Successfully logged in!"
P.S: i am running cloudstone on three vms on a single host machine.
I allocate 256MB memory to each vm. In the "driver tab", i use 25
concurrent users. Is there any possibility that the frontend is too
busy to serve too much users?

It can mean both but in this case the run log shows that all
"Login" attempts have failed which looks like a setup problem. Try
to login with one of the username/passwords in the browser to see
what error message you get. You can select a user from the database
or log file, or create a new one.

Hi Mohammad,
Thanks for your reply. I think the websit
"http://ip.of.frontend:80"; works well, since the browser can
display the "Web 2.0 Php Application" correctly.
Acctually, i am wondering wether the "Failed" results mean
that the installation or configuration of cloudstone is incorrect?
Or, "Failed" means that the system performance is not good enough?

Hi,
These exceptions are not critical. You need to install the proper
tools (e.g., nicstat and mpstat) to get rid of them. For the last
one you should pass the correct path to the Mysql error log file.
I examined the run log of your experiment and it seems that there
is a problem with your setup. Check to see if you can access the
Olio application in your browser by pointing the browser to
http://IP.of.frontend:port.

Mohammad
