Editing Remote Instances

A remote instance defines the connection details that OpCon uses to communicate with a separate OpCon database. Use this procedure to update the connection properties of an existing remote instance in Enterprise Manager.

For conceptual information about each field, refer to Remote Instances in the Concepts online help.
