Lr Advance Param Function In Loadrunner With Example

This function is not recorded during recording. We manually insert this function whenever there is a need of it. lr_advance_param works depends upon the settings we give in parameter list (ctrl+L). lr_advance_param is like update value on each occurrence. Whenever we want to update a parameter value in the same iteration we use lr_advance_param. For example when we want to use two parameters Google and Bing in one Iteration. Usually the Vugen takes the first value google and if we want to use the second value in the same iteration we use  update value on each occurrence  in the parameter settings. We can do the same using lr_advance_param function. Example: I have set following settings in Parameter Select Next Row:  Sequential Update value on:  Each Iteration If we want to take the next value in the pramater list we use lr_advance_param as shown below. Parameter Name:  DomainName Google Bing Yahoo Ask Vugen Script: Action () { web_u

Error -27492: "HttpSendRequest" failed, Windows error code=12057 (certificate revoked) and retry limit (0) exceeded for URL="

This error occurs when using WinInet replay instead of sockets with Integrated Authentication enabled in run-time settings. The purpose of this was to allow vusers to use SSO with SPNEGO authentication in an IBM WebSEAL environment. After spending some time with the mystical HP level 3 support, they identified an undocumented flag which helps out significantly in this. So, instead of using the WinInet replay engine (which is not encouraged by HP) you should do something similar to the following. vuser_init() {             // Preferred run-time settings             // Browser -> Browser Emulation        // [ ] Simulate a new user on each iteration        // Preferences -> Options        // Enable Integration Authentication [Yes]             web_set_sockets_option("INITIAL_BASIC_AUTH","1");             web_set_user("DOMAIN.LOCAL\\username",                         "password",                         "s
