Window or object is not displayed

Hi
Facing a problem "Error: nca_edit_set("B_LOGON_TI_USERNAME_0","rms12dev") failed, Window or object is not displayed."
I have added the record=names in the URL. but im not sure whether i have to add this in some other place in application files.

Here we are accessing the application with web browser.
Please let me know whether installing ORACLE is mandatory in the VGen machine
