Memory requirement also called as Memory footprint for a Vuser can be called as a function that is dependant on Vuser type (Web, CITRIX, SAP GUI); application and system where you
intend to run the test.
So if your Web/HTTP Vuser takes 5MB when running as a process, 50 Vusers would take 250 MB. Then remote desktop connection , third party program (that is continuously running in background) , memory consumed by application all summed will give you the memory requirement for a test.
You can calculate it empirically. Do it for say 10 Vusers and than extrapolate that requirement for x no of Vusers.

Hello,
You have given an assumption that if a Web Vuser takes 5MB,My question here is:
Is there any way to know how much amount of memory a single web HTTP Vuser actually captures??
.Where can we see??
Waiting for your response!!
Thanks,
Rajiv

Set up a Windows monitor to measure the memory consumption. Ramp up the Vusers slowly and closely monitor the memory resources, you will get an idea.

Posted by Rajiv | April 21, 2009, 8:25 pmHi,
Once vusers running as a thread,How much memory will allocate 1 vusers taken ?
Please reply
Cheers

It is based on the OS… and it will allocated from total RAM size…. it will vary from protocol to protocol.
Refer HP Loadrunner Footprint document for more details. refer following link … u will get/(download file) more info…

Posted by suresh | January 8, 2010, 9:28 pmNot sure if this was ever encountered in Loadrunner Program.
We use Load Runner as a replacement for Rexx in mainframes.
Is there any limitation on the number of fields being used in LoadRunner.
The program we are testing uses a file pointer.
Based on a specific value in input file program executes another sub-routine and after it processes that it returns to the called routine.
Unfortunately the file pointer is being lost and program reads only 1 record and when it tries to read next one it encounters a space.
Same program if i just give a display before that sub-routine call and comment the sub-routine it reads all the records from input file. Also READ happens only in the called para but not in sub-routine.
Did anyone face this issue.
Thanks,
