Service providers that wish to create Oracle Advanced Support Platform users must first ensure that the individual is not already a contact for the customer organization in Oracle Advanced Support Platform.
To determine whether a customer user already has a registered Oracle Advanced Support Platform username, and therefore doesn’t need to be added as a contact:
Open a Web browser and navigate to https://myprofile.oracle.com/EndUser/faces/profile/createUser.jspx?tid=minimal. See Logging in to Oracle Advanced Support Platform.
In the Email field, enter the customer username (email address.)
If no message is displayed, continue with Oracle account creation.
If the following message is displayed, “Username already exists. Please log in or enter another username”, then the customer username has been registered.
