The Vusers can accept command line parameters when invoked.
For a complete list of the command line options, type mdrv at a command prompt from the LoadRunner bin folder, without any arguments.
To send command line parameters to a Vuser from within VuGen, add the attributes and their values in the runtime settings. For details, see the General > Additional Attributes runtime settings view.
To control a Vuser from the Windows command line, type mdrv at a command prompt from the LoadRunner bin folder, with the desired commands. You can also add custom user parameters, after all the other driver parameters. For example:
mdrv.exe -usr c:\tmp\Vuser\Vuser.usr -out c:\tmp\vuser command_line_params
There are several Vuser API functions available to reference them (such as lr_get_attrib_double, and so forth). For details, see the Online Function Reference.
Note: The Linux utility, run_db_vuser, does not support some of the standard Windows command line options. For details, see How to Run a Vuser Script from a Linux Command Line.
