Hi Amir. Your 'workaround' using JMeter 1.7 seems reasonable given 1.7's feature set. Mike advised using the nightlies, to gain access to the User Parameters config element. The online manual says: http://jakarta.apache.org/jmeter/usermanual/component_reference.html#User_Parameters 13.4.10 User Parameters Allows the user to specify values specific to individual threads. Try this: Test Plan Thread Group (numthreads: 4) User Parameters (set up the number of users to match your numthreads) (set up the parameter value sets you need for each user) HTTP Request (your login request, which uses parameters from above) You can also use more HTTP specific config elements (User Parameters are generic and can be used across all JMeter objects). These are available in unstable/1.7.3, as well as the nightlies: HTML Parameter Mask http://jakarta.apache.org/jmeter/usermanual/component_reference.html#HTML_Parameter_Mask HTTP User Parameter Modifier http://jakarta.apache.org/jmeter/usermanual/component_reference.html#HTTP_User_Parameter_Modifier I am using HTML Parameter Mask myself at the moment for a large population of synthetic user identities in my web app's logins. This happened to be best because of the existing tools the end to end system has for generating user identities and related data. Adio, John Kavadias. -----Original Message----- From: Amir Nashat [mailto:[EMAIL PROTECTED]] Sent: Friday, September 06, 2002 12:54 PM To: [EMAIL PROTECTED] Subject: Attn: Denis Wang....RE: multiple user login in multiplethreads of one loop This is in response to an earlier post dated August 27th.

It is only available i>n the nightlies, however. >-Mike However, I believe you can currently do it with 1.7 Beta 3. My solution is as following: 1) Using an interleave controller is not correct. This will only allow you to submit one login for each loop iteration in order from top to down. Thus, loop one user1 login occurs. Loop two user2 login occurs. If you had a loop three user3 login occurs but from what was stated only 2 loops were used. 2) In order to obtain the effect that was required then four thread groups should be created. Each thread group will have only one thread per group and only one loop per group and a ramp up period of 0 seconds. Also, aside from the login being included as well each thread group will have a constant timer set approximately 1000 ms apart from the value of the timer in the previous thread group(e.g. thread group one will have a constant timer set at 1000 ms...thread group two will have it set at 2000 ms...etc). Since each thread group runs concurrently then all four threads will run at the same time with each login 1000 ms apart thus simulating exactly what Denis needed. Now comes my question...sorry for the mess. How exactly would Mike's solution have worked in this same scenario? I am curious to find out. I don't know much about this new UserParameter config and after going through the archives and creating the javadoc from the source I still couldn't get a clear understanding. Mike, if you have the time I am all ears!! or I should say eyes... :>) amir -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
