Max Concurrent User for HTTP/HTML Protocol

[RaJ]

Could any one clear my doubt regarding to loadrunner ,my question is
that what is the maximum Vuser can run concurrently using HTTP/HTML
protocol in loadrunner controller?

[Anand]

I believe you are only limited by the number of licenses you/your
company hold and the performance capacities of the controller.

There used to be a document that details the footprint for each kind
of Vuser on the Mercury support site, but I do not know whether it is
available on the HP Support site.

[Krishnakanth PPS]

how many you want to run??

[rohit sharma]

Hi,

As per my knowledge for 1 Vuser 2MB. so based on your system capacity you can run n number of Vuser.

With Regards
Rohit

There is no license problem. The load runner which i am using can ramp up 999 Vuser concurrently but my question is that is it fixed if i m using any particular protocol .
let me clear some doubt

1- I created a scenario for one Script which is recorded using HTTP/HTML protocol.I ran the script for 100 Vuser .After 49 Vuser ramped up  Some Vuser started failing .Error which i was getting is "HTTP Server connection prematurely shutting down".

2- Is it depend upon system configuration  like  CPU  RAM  etc.?

3-- is it depend upon port through Vuser sending request to server that might not allowing more then 49 user??

Plz Help!!!

Hi Rajiv,

generating Vusers is only dependent from LG (load Generator) memory
perspective... if you are trying to simulate 100 VUsers (HTTP only)
then a 2GB machine would be enough..

But the error you are getting is from application server side.. its
not a client side error..

check with the application configuration / deployment team... what is
the no of sessions / active threads it can generate/handle.
Check the CPU and Memory usage of application server during this
process...
when you get the below mentioned error (while executing the test) try
to access the application manually and see whether you can access all
the flows... If you are getting the error manually then check with the
application dev team or deploy team to sort out the issue.

Regards,
Sunil

I believe this is an application/script error, not a loadrunner
error.
You mentioned that "some vusers are failing after 49 are up and
running." Does that mean, the total number of Vusers gets to more than
49 ever or do all Vusers fail after 49 are running?

no arvind not all user fails affter 49 Vuser rampup rremaining User which was in int section start failing with same error.. 49 Vuser passed all transection.

[Rajiv kumar]

could you please tell me from where i can get this memory usage related  info??

[Rajiv kumar]

sunil my machine configuration is Having 3 GB RAM .it's not like all Vuser fail at the end
if i will run my script for 49 user then all will pass but i will increase Vuser then it's will start failing

[Rajiv kumar]

if it is related to Memory usage by Vuser can any one provide some useful link ..?

i cant the link rite now.. but search in google for " mark tomlinson vuser footprint".

 there is a blog written by mark, and it shows how to calculate it

hi rajiv,

check this link...

Hi,

 

As many as you are willing to Pay for and provided you have enough generators.

 

Enjoy,

OK... a sustaned load without faults with 50 users or less is what
your saying.
But then you ramp towards 100 users and everything above that fails.
And you believe your controller is out of memory. Add a couple
agents.

To me it looks like your connection pool on the server side is full.
But then its your system.

Hi

 

Add the following code in your script and let me know if it works after that.
 
web_set_socket_options("MAX_CONNECTIONS_PER_HOST","1");
web_set_socket_options("IGNORE_PREMATURE_SHUTDOWN","1");

hi ,

the no of concurrent users to use in LR depends on license type. to
more information download the manual from the below link. to download
the loadrunner manuals from this link u have to register in this site.

hi abdul,

can u plz tell me actually where we need to add those code???/starting of the script/end, init, action or in the end section.
pls let me know all these......

thanks,

You should listen to SuperKevy and investigate hard limits in the
number of connections allowed on the server.

Try browsing manually while the virtual users are failing. If you see
errors then this proves that LoadRunner is not at fault.
Look at the graphs of TCP connections, CPU and RAM on the server side.
Their shapes will give you clues to what is happening.
Try to understand what the server is doing when it fails, find the
error logs and read them. Learn about the technologies that you're
testing, find the experts and ask them for advice, get the developers
to draw you diagrams until you understand each component in the
system.
Use smaller scripts to pinpoint the failing component in a scientific
manor: Could it be connections to the web server? Could it be web
services called within the pages? Could it be connections to the
database?
Once you have found the problematic component, examine and adjust the
configuration, repeating the test each time you change something. If
you have exhausted all available options, ask the developers to add
additional error logging and start again.
