Create/Edit/Select Database Connection

The database connection dialog box displays any existing connections. Depending on the context, you can select a connection to connect to the database, edit the information about existing connections, or specify information while creating a new connection. (See Creating and Editing Connections.)

Connection Name: An alias for a connection to the database using the information that you enter. (The connection name is not stored in the database, and the connection is not a database object.) Suggestion: Include the database name (SID) and user name in the connection name. Example: personnel_herman for connecting to the personnel database as user Herman.

Username: Name of the database user for the connection. This user must have sufficient privileges to perform the tasks that you want perform while connected to the database, such as creating, editing, and deleting tables, views, and other objects.

Password: Password associated with the specified database user.

Role: The set of privileges to be associated with the connection. For a user that has been granted the SYSDBA system privilege, you can specify a connection that includes the privilege.
