In loadrunner to capture the Dyanmic value in each run of
the script execution.
Two types of correlation are there in loadrunner.
1.Auto correlation 2.manual correlaion
The function of correlation is Web_reg_save_param("param
name","Lb=","RB=","ORD=",LAST);
web = webapplication(HTTP)
reg = Regestration
save = saving the next comming dynamic value into the
parameter name
param = parameter
The web_reg_save_param() function registers a request to
retrivew dynamic information from the downloaded page and
save it to the above mentoned parameter name.
1.parameter name:-it captures the newly server generated
value and replace through the script.
LB: it indicates the left boundary value of the correlted
value.
RB: it indicates the right boundary value of the correlated
value.
ORD value: ordinal vlue. The specific position of the
correlated value with the left and right boundary match
cases.

Answer / rajvelur
Correlation is used to obtain data which are unique for each
run of the script and which are generated by nested queries.
Correlation provides the value to avoid errors arising out
of duplicate values and also optimizing the code (to avoid
nested queries).

Process for Auto and manual corelation :
Auto Correlation Process: once u execute the scripts and
click Ctrl+f8 system displaying what values u have to do
correlate select the value and click Correlate ...
so Auto correlation done u r scripts
When u want to do Manual Correlation :
If u know the values where exactly changing fine other
wise
After scripts creation :
Step 1: go to run time setting change the Log option
select Extended log and select 3 check box
Step3: Run the script " completion of run "
Step 3: Click Ctrl+ F8
Step 4: check the values where exactly changing and what
value while recording and what value while executing time
system displaying ..
Step5: Take Replay value and go to Replay Log and find out …
Step 6: Take the complete line values exactly where it’s
and paste on notepad
( Make Sure u should know what transaction
this value in your scripts …when u click the value in
replay log in script Tree view system shows the transaction
name …
Step7: go to that Transaction above and right click mouse
Insert-- New Step-- Service- Find Web_reg_save_param and
click OK
Step 8: Enter the Param name ( make sure what name u given
here u should replace the value place in your script)
enter the LR and RB and select Search depending on Body or …
Step 9: Click OK
Step 10 : Change ( Replace ) the Param name
Step 11: Save the script and run …
When u want to check the results either u r scripts capture
the dynamic value or not after completion execution go to
replay log find with Param name …if u r did correct manual
correlation system displaying new dynamic values beside of

Correlation means "Handled the data which is dynamically
generated by the server".
1.Manual correlation.
2.Automation Correlation.
i.After Recording of the script.
ii.During Script Recording.
1.->Handled the correlated data without help of the tool
functionalities i.e Manual Correlation.
2->Handled the correlated data with the help of the tool
functionalities i.e Automation Correlation.
Correlation why means...........
We can Handling into the Web Applications like
1.OnlineReservations(Train,Bus,Airlines)->When u complete
transaction of reservation server it will creates one
OrderNumberID/TransactionID.
2.Bank Applications->Customers doing Online DDRequests it
will generates Automatic DDRequest ID.
3. MyNaukari->Users without performing actions just login
and they can do other work.when it exceeds session it will
automatically display ur Session Expired.(SessionID).
Why means we can reduce the burden of Application Server.
Then we can increasing into the our application performance.
Then client expected Response time,Throughput,Resource
Utilization.....all we can satisfied.
