Invoke Vugen from a .net app

1. Add System as a Reference to the project
2. Here is actual code to run the script -
Shell("[Vugen Installation Folder]\bin\mmdrv.exe -usr [Full path of the script] -vugen_win 0", AppWinStyle.NormalFocus)

Example :

Shell("C:\Program Files\HP\Virtual User Generator\bin\mmdrv.exe -usr C:\FlightsTool\FlightCal.usr -vugen_win 0", AppWinStyle.NormalFocus)
Note: Neither Vugen now the Run Time window will be visible as the script runs in the background, however the results, log files, etc will be still be saved in the usual location.

Sample date conversion program using vugen scripting in Load runner

char *ConvDate;

//Call date conversion function
dateConv("10/JUL/2009", ConvDate);
lr_output_message("date is %s",ConvDate);
return 0;
}

//Date conversion function

dateConv(char *MyDate, char *ReqDate)
{
lr_save_var(MyDate,2,0,"Date");
lr_save_var(MyDate+3,3,0,"pMonth");

lr_output_message("Month is %s",lr_eval_string("{pMonth}"));

if(strcmp(lr_eval_string("{pMonth}"),"JAN")==0)
lr_save_string("01","Month");

/*  Similar rest of the code goes here....*/

else if(strcmp(lr_eval_string("{pMonth}"),"DEC")==0)
lr_save_string("12","Month");

lr_save_var(MyDate+7,4,0,"Year");

ReqDate = lr_eval_string("{Month}/{Date}/{Year}");
lr_output_message("date is %s",ReqDate);

return 0;

How do I identify the SSL protocols and certificates used by a website when testing with LoadRunner

Cause -Understanding the SSL Protocols and certificates used by a website.
Solution -To identify the type of SSL and certs used on a web server, type the following commands from a Loadrunner client workstation :

• Go to the Loadrunner/bin directory.
• Type "openssl", this will then display an >openssl prompt.
• Type "s_client - connect www.test.com:443" where test.com is your web site.

This will then return details of the web servers SSL configuration.

Other usefull commands to use in LoadRunner Web protocol scripts are as follows:

web_set_sockets_option("SHUTDOWN_MODE", "FAST");Allows the disconnection of the SSL session to be completed quickly.

web_set_sockets_option("SSL_VERSION", "TLS");
web_set_sockets_option("SSL_CIPHER_LIST", "RC4-MD5");These options allow the version and cipher for SSL to be specified. Possible versions and ciphers are detailed in the Loadrunner Function Reference.

web_set_sockets_option("TRACE_SSL_IO","1");This option will detail all SSL IO in the normal vuser log.

web_set_sockets_option("PRINT_SSL_INFO","1");This option will detail the version and certificate used in the SSL configuration.

Error: “License manager does not support objects of this type or license is invalid”

Verify the followings:

Check the properties of the license key. If you apply a license key that has components that does not come with that version of LoadRunner, you will get this error.

Example:Apply WAN emulation license (introduced in LoadRunner 7.6), or J2EE diagnostics (Introduced in LoadRunner 7.8 FP1) license on LoadRunner 7.5
Make sure that you are applying the license key on a machine where the license is generated for. In LoadRunner7.x, license keys are host lock. If you try to apply the license key on a separate machine, you will get this error.

Error: “Cannot install license information, probably access to system resource was denied”

Solution:

This error indicates that you need to log in with local administrator permission, since you installed the product with administrator permission. If you still get the error after login as local administrator, run setlicensepermissions.exe from the \bin directory to change the registry permissions
