The first step in starting Oracle Applications is to enter the appropriate URL for your site in an Oracle Applications certified browser. After starting Oracle Applications, the first window you see is the login window. You need an Oracle Applications username and password to log in to Oracle Applications. It is different from the username and password you use to log in to your computer. If you are not sure of your Oracle Applications username and password, consult your system administrator. Oracle Applications security is based on your Oracle Applications username. Your username connects you to your responsibilities, which control your access to applications, functions, reports, and data.
