Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
This class is created whenever the OracleDataAdapter encounters a situation that it cannot handle.
If the severity of the error is too great, the server may close the OracleConnection. However, the user can reopen the connection and continue.
Example
[Visual Basic, C#, C++] The following example generates an OracleException due to a missing database, and then displays the exception.
[Visual Basic] Public Sub ShowOracleException() Dim myConnection As OracleConnection = _ New OracleConnection("Data Source=Oracle8i;Integrated Security=yes") Try myConnection.Open() Catch e As OracleException Dim errorMessage As String = "Code: " & e.Code & vbCrLf & _ "Message: " & e.Message Dim log As System.Diagnostics.EventLog = New System.Diagnostics.EventLog() log.Source = "My Application" log.WriteEntry(errorMessage) Console.WriteLine("An exception occurred. Please contact your system administrator.") End Try End Sub [C#] public void ShowOracleException() { OracleConnection myConnection = new OracleConnection("Data Source=Oracle8i;Integrated Security=yes"); try { myConnection.Open(); } catch (OracleException e) { string errorMessage = "Code: " + e.Code + "\n" + "Message: " + e.Message; System.Diagnostics.EventLog log = new System.Diagnostics.EventLog(); log.Source = "My Application"; log.WriteEntry(errorMessage); Console.WriteLine("An exception occurred. Please contact your system administrator."); } } [C++] public: void ShowOracleException() { OracleConnection* myConnection = new OracleConnection(S"Data Source=Oracle8i;Integrated Security=yes"); try { myConnection->Open(); } catch (OracleException* e) { String* errorMessage = String::Format( S"Code: {0}\nMessage: {1}", __box(e->Code), e->Message ); System::Diagnostics::EventLog* log = new System::Diagnostics::EventLog(); log->Source = S"My Application"; log->WriteEntry(errorMessage); Console::WriteLine(S"An exception occurred. Please contact your system administrator."); } }
