Ajax (Click and Script) Miscellaneous Tips
Caution: Support for the Ajax Click & Script protocol will be discontinued in upcoming versions of LoadRunner and Performance Center.
Do not use the Ajax Click & Script protocol for new scripts.
We recommend that you migrate your existing Ajax Click & Script scripts to another Web protocol such as TruClient - Web or Web - HTTP/HTML.
The following additional tips may help you in troubleshooting problems that you experience with click-and-script Vuser scripts.
Note: Some of the items below apply to specific click-and-script protocols only.
Search for warnings or alerts in the Output pane.
Verify the response of the previous step is correct using web_reg_find. For more information, see the Function Reference.
For problematic steps or those using Java applets, use Alternative Navigation to replace the Web step with an HTTP level step. Note that the HTTP level steps may require manual correlations. To perform Alternative Navigation, select a step in the Step Navigator, or the text in Script View, and select Replace with alternative navigation from the right-click menu.
If you are using the Kerberos Protocol for authentication, you must customize VuGen to properly convene authorization sessions. Advanced users can attempt to perform this customization themselves.
In order for the Kerberos Protocol to work properly, create a krb5.ini file and put it in an available folder. Save the full path name of krb5.ini into the KRB5_CONFIG environment variable.
The krb5.ini file should contain detailed information about each domain (KDS and AS addresses) and trust chains.
