OracleException

Cannot change the database.

The OracleConnection draws an open connection from the connection pool if one is available. Otherwise, it establishes a new connection to the database.

NoteNote:

If the OracleConnection goes out of scope, the connection it represents does not close automatically. Therefore, you must explicitly close the connection by calling Close.
