When you import an Oracle database into an enterprise industry model project, you specify a password. Whenever users open projects that contain industry models that correspond to the Oracle database, Infrastructure Map Server supplies this password to Oracle “silently” (without any user interaction.
You must change the password (or remove the industry model from projects) if the password for the Oracle database changes. This can happen if someone changes the password using an external tool, or due to expiration. In Oracle 11g, passwords expire after 180 days (unless your Oracle administrator specifies otherwise).
