According to the stantards Auto Correlation may satisfies
only 50%.
Some times autocorrelation Didn't Identifies the string
values. And aslo it may not found the session id
automatically generates this may confuse to tester.
Always Better to go for Manual Correlation.
i agree with all the above, manual correlation is best and i will suggest one thing. when you are not able to find LB n RB, then do auto-correlation, note down the LB n RB, then go for manual correlation. We can use auto correlation like this also..
The Manual Correlation or the Automatic Correlation Needs
both the Left or Right Boundaries
We will go for automatic correlation only if the particular
parameter will be occured in multiple requests and
different values in each request.
Hence we can keep the Left Boundary and Right Boundary in
automatic correlation and record the script and each
instance it will replace with a new correlation value.
Example:- when we are recording any .net application we
generally have View State and Event ID Validation then
which will be occured in almost all the requests and
different values but the left and right boundaries will be
one and same hence if we automatic this correlation
function then it will repalce all the instance properly
other we need to manually do it which takes lot of time.
Manual Correlation:- we generally use the this when the
dynamic value from the server is generated only at one
instance and you can capture it manually rather than
automating it.
Example:- Order number it will be generated only once by
the server but used in multiple places of the script.
We can also automate this also but some times this will
replace with unnecessary values in the script which is not
good and it leads to confusion, hence we will not do
automatic correcation if it in single instance

1.How can you Calculate load / stress testing in manually ?
Is there any Calculators are available?
If yes
Please send me the Formulas?(I mean how the tools Ex: load
runner, JMetter, Silk Performer .calculating the
load )
I need to perform a 4hr test run in performance center 9.0
there i need to rampup 10 users after 1 hour. I selected
the run tab and added users to down state -> Ready state->
initialise-> Run state. 10 users ramped up successfully for
the next 1 iteration only after that the 10 users
automatically goes to the stop status. But i want the
ramped up users to be carried out for the next 3 hours.
Please help me out how to do the rampup successfully for
the remaining time period.
i want to chek the load of users on sign-in page of website
i want to knw tht by the option transcation i will do it or
if yes do i have to select only tht snapshot for it and wht
is trancation and wht is the used of it ?i m using trail
version of loadrunner8.1
Dear Gurus,
I have an interview in a company in Chicago and my latest
project has the following description can anyone let me
know what would be the QUESTIONS that can be asked from the
following.
Thanks,
 Developed test cases and test plans and analyzed
the test results using for LoadRunner.
 Involved in Load/Performance Testing
 Created LoadRunner Scenarios and Scheduled the
Virtual user to generate realistic load on the server using
LoadRunner.
 Created and implemented Performance tests using
Mercury Interactive LoadRunner.
 Enhancing the scripts using Generator and performed
Parameterization and Correlation to meet the requirements.
 Involved in performing load and stress test on the
application and server by configuring LoadRunner to
simulate hundreds of virtual users and provided key metrics
to the management.
 Configured and Using Performance Monitor to monitor
and analyze the performance of the server by generating
various reports for CPU utilization, Memory Usage, load
average etc.
 Involved in conducting stress test and volume test
against the application using LoadRunner.
 Used Quality Centre to invoke the scripts and
initially performed the baseline testing and organized all
the scripts systematically and generated reports.
 Performed regression testing for every modification
in the application using Win Runner.
 Involved in performance testing of servers load
and scalability by creating multiple Virtual Users by using
Load Runner Virtual User Generator component.
 Created detailed test status reports, performance
capacity reports and graphical charts for upper management
using Load Runner analysis component.
 Involved in parameterization of script using VuGen
in Load Runner.
Please.........
AFter generation the script for a application i am trying
to make correlation but it is showing 404 error after
customization.could u please help me how i have to make
correlation give me steps please
