Jmeter - why linux gives different answer than windows?

1
votes

I wrote a test plan on Windows 7. I remotely started a test on two machines, both Windows Vista. A problem came up when I tried do same thing on Linux - I used the same test plan.

I can login a group of users and simulate their behaviour, but when I try to log them out nothing happens.

On windows, they are logout but linux gives me empty response data. Listeners show green status so I'm rather confused to what's going on. Should I change something in properties or is it problem with my script?

EDIT:

Script:

  1. Login user using authorization data. every user gets different JSESSIONID.
  2. Simulate user behaviour using Access Log Sampler.
  3. Logout user.

On Windows, everything works fine login and logout. Listener shows: sample result, request data and response data for every sample.

On linux response data is blank for every sample.

Examples of Sample result for windows and linux

Request Data is the same for both.

Response data for linux is blank.

EDIT2:

  • Test Plan
    • setUP Thread Group
      • Clean cache server
      • Clean file with JSESSIONID
    • Thread Group
      • HTTP Request Defaults
      • Login (once only controller)
      • Acces Log Sampler
      • using beanshell script i save JSESSIONID (cookie variable) to file
      • Cookie Manager
    • tearDown Thread Group
      • HTTP Request Defaults
      • read JSESSIONID from file
      • logout all users
      • Cookie Manager
    • result tree
    • Summary report

Logout must be performed after all samples from access log are done. That's why i save JSESSIONID to file to share same session between thread group.

Ok somehow I eliminate error with response. Apparently there was a problem with java version on linux server.

Current problem is that when i start remotely script on Linux it doesn't follow redirect. The same script on win XP or Vista follow redirects and user is logout. Exp.

GET connection.rpc?logout=D5D076123FD6CCBF137FE1673F531006

On Windows I get two redirections and user is logout.

On Linux I don't get redirects and user is not logout.

It is strange because during authorization there are a few redirects and linux performs them correctly.

Could you provide more information? This is hardly enough to go on. – beatgammit
I add more information – kendzi
Show your test plan structure and if you can show response tab in view tree result – UBIK LOAD PACK

You should check that jmeter accesses correctly your jsessionid file on linux:

  • check path is ok (no )

  • check read access

If you are using distributed testing, issue may be that file is not found by agent or some file is overwritten by another agent

Problem is solve, yupi :) It turned out that the target server has set the lock for some machines. On such a machine was a Linux. That is why I could not log users in a separate thread.

Therefore, if someone encounters a similar problem (from one machine request are handled correctly from another are not), he should check if his machine have correct permission in my case i needed to do correct entry in adm.list in test server.
