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.

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.");
   }
}
