When creating the Spotfire Server application database on Oracle Database 12c, you will be using the oracle_install scripts present in Spotfire Server downloaded package. After providing values to the variables like SERVERDB_USER = spotfiredb, DEMODB_USER=demodata, and ACTIONDB_USER =actionlogdb, when you execute the create_database.bat, you may encounter the following error:
ORA-65096: invalid common user or role name
Cause: An attempt was made to create a common user or role with a name that was not valid for common users or roles.
In addition to the usual rules for user and role names, common user and role names must start with C## or c##
and consist only of ASCII characters.
Action: Specify a valid common user or role name.
In Oracle 11g, with the same user names you will not get any error.
