Question { GE, 39586 }

what is Rendezvous Point?


Answer

It is like a traffic signal.

In general scenario using loadrunner we are running the
test for some duration like 30 min or 1 hr. In this
scenario all the vusers not hitting the transaction at a
time. some of the users may wait between the transactions.


if you want to stress on the particular business
transaction then insert Rendezvous. it will stop all the
vusers at that point and it i will release all the users at
a time .

Question { 28334 }

What is think time? How do you change the threshold?


Answer

Think time means the time gap between the two actions done
by the user

It is used to Generates a real time scenario

Means, Suppose if you take two users A and B, A is expert
with Yahoo application And B is littlebit poor, then A will
done the Actions faster than B. B will wait some time
between the actions. that time is called think time.

In real time scenario we will use random, 50-150%

Question { IBM, 13009 }

what is think time when u will use it?


Answer

It is the time, that a normal user waiting between two
actions.

Use of this think time is to simulate real time scenario.

We can limit the think time or we can modify the thinktime.

There is onemore timeparameter in Loadrunner is THRESHOLD
TIME.
It is useful to limit the think time.i.e suppose we enter
threshold as 5 sec, Loadrunner wont generate any Function
into the script

What is Latency in LoadRunner? What is Network Latency?
could u explain in detail how to define this network Latency
in LoadRunner?
Thanks in Advance


Answer

when client send a request to the server,server sends the

time taken to the request & response in the network side.
this latency depend on the network bandwidth.
