jmeter: multiple sessions

Thu, 09 Feb 2012 13:52:17 GMT

Hi,

using QVScriptGenTool I realized my jmeter script.

Testing with 50 threads (users), I find in session log a lot of messages like "Killed because Named User Cal was needed from another client". Every thread interrupts started session.

In Qlikview server we have only Named User CALs and Document CALs.

NTFS authorization is required.

Different logins ,added using HTTP Authorization manager, are not used. Only the login of user that run jmeter is used.

Someone launched the script with more contemporary sessions in qv10?

I am working on this issue also. Have you found a solution?

Did you see the document called "GenericTool-BA-how-to-enable-and-disable.docx" in the QVScriptGenTool package?

Thanks for your suggestion about the document called "GenericTool-BA-how-to-enable-and-disable.docx".

Unfortunately this solution uses dms authorization.

I need ntfs authorization in order to identify qlikview administrator users and launch dynamic update commands.

I tried to modify jmeter in order to add ntlm support (see http://hc.apache.org/httpcomponents-client-ga/ntlm.html or http://agilitator.com/blog/?p=987), but without success.

Alex -

The environment we wanted to test was using QVWS rather than IIS. We were trying to use the password mechanism that comes with QVScriptGen. Our main problem was that when we tried to pass credentials in using the password file, IWA (integrated windows authentication) always intercepted and passed my local logged in account credentials, rather than the accounts we were trying to use in the password file.

Our workaround was to install IIS to run on port 8080, side by side with QVWS, and disable Windows Auth and enable Basic Auth in the IIS config. This forces a Basic Auth dialog to pop up when you go to AccessPoint, and IWA doesn't intercept. JMeter has the ability to pass in Basic Auth credentials from the password file, which we utilized. The Basic Auth users in the password file are real Windows users. We are still running in NTFS mode.

One more thing - the generated JMX had to be modified in JMeter to enable Basic Auth. It's only a few steps that need to be done.

Hey Gary,

Can't you just change authentication scheme from "NTLM" to "Basic" in config.xml for QVWS in your case, instead of installing and configuring IIS?

Just a thought, never tried it together with jMeter, but that's how I change my QVWS to support Basic auth or Kerberos if required ("Negotiate").

Cheers,

Can we? How would we know? There's no documentation or discussion of this option.

Hi Bjorn,

I am also using the Jmeter with Qlikview GUI generator.

Used to get the error

"Killed because Named User Cal was needed from another client". Every thread interrupts started session.

But i have changed to use the cookie license in the xml file. And i am not getting the error . But the problem is in the even log it is having the messages Mount, Document Load. It has only the Ticket Created ,Ticket Found. Also Cpu spent in session log is always zero . And the QliKView user is shown as ${H}. It would be great if you could suggest some solutions.

Hi brindlogcool,

If the QlikView user is shown as ${H} or ${H1}, it seems that the script expects a file with headers which it does not find. If the "Authorization enabled" checkbox is checked on the Properties tab in the QlikView Script Generator GUI, the script will require a file containing authorization variables.

That file should be defaulted to "..\SupportFiles\usrpwd.txt" so it might be that the file is missing (or folder structure has changed) or no file at all has been specified.

Thanks Sebastian,

I have rechecked my supportfiles.

There is no change in the folder structure and it is fine. I have specified the username(without domainname) and password in the usrpwd file.Do i need to provide with Domain/Username.Also for more clarification QVWS authentication is NTLM. Do i need to change it to Custom Header.

Where can we get this QVScriptGenTool ?

Hi,

You can find the tool and other useful information on the main page of this community group. The direct link to the tool is http://community.qlik.com/docs/DOC-2705.

Hi Sebastian,

I am trying to figure out what authentication type to use NTML or Basic, our Qlikview server default authentication type is NTML (under System > Set up> Authentication), I am testing a QV server licensed with 100 named user CALS.

I understand that for testing scenario of multiple users acessing different documents in different JMeter instances, should we choose NTML?

For NTML one authenticated windows user account which runs load test needs to be enough, we need not create and supply other test windows accounts, right?

When do we need to choose authentication type Basic?

please suggest, I appreciate your help!

Thanks,

Swetha

Hi,

Actually I would recommend using header authentication, if possible. Set the environment up to use header authentication, and do the same for the tools, which means creating a textfile with usernames for the users you want to simulate. No extra windows accounts need to be created (you still need the one running the script to belong to the domain etc)

Basic can do the trick as well, but there is some more steps to take so I would try the header first.

As an advice, before running multiple users, run the script with one user only to verify that one user can be simulated, then test with multiple users.

Hi Sebastian,

Continuation with the last response on using header authentication, does authentication type has any dependence on Cals Type avaliable on QV server?

We have QV server licensed with 100 named user CALS.

Could we able to access files from QV server with only Named cals and header authentication type setup?

Or do we need Session cals for header authentication type setup?

Thanks,

Kamal

Hi Kamal,

You are not limited to have session CALs if using header. If you have Named user CALs and have set up the environment to assign them properly it will work with the tools if it works for single users accessing the document(s) manually via a browser.

Regarding how it should be setup on the server side,that information can be found the Qlikview Server Reference Manual.

Do we need DMS Authorization to be set for Multiple User and Basic Authenticatin?. Can we still create user in Local machine and use Basic Authentication. I have checked that it works if user are created in the QVS using DMS and Basic Authentication. Any document related to user creation on Local Machine and Basic Authentication wouild be great

Hi Gary,

Might you be able to help me with resources on how you setup jMeter to use Basic Auth as well as IIS config?

Hi Sebastian,

Could you explain, please – what are other steps that need to use the scenario of multiple users accessing with just NTLM authentication?
