Examples

The following example generates an OracleException due to a missing database, and then displays the exception.

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.");
   }
}
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

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.
