Hi all,

I'm using ODP.NET , OracleDataAccess.dll

1. cannot find this server message in the documentation
2. here is the code where this exception occurs:

Dim dataadapter As New OracleDataAdapter(cmd)
dataadapter.ReturnProviderSpecificTypes = False
'dataadapter.SafeMapping.Add("*", GetType(System.String))
dataadapter.MissingMappingAction = MissingMappingAction.Passthrough
'dataadapter.MissingSchemaAction = MissingSchemaAction.AddWithKey

dataadapter.Fill(Dataset1, table)
Catch ex As OracleException
MsgBox(".Fill1 dbAccess: " & ex.Message & " bei Tabelle: " & table & _
Environment.NewLine & "Aufruf: " & strSQL)
Return False

many thanks for all replies

         connection lost contact
    Cause:      1) Server unexpectedly terminated or was forced to terminate. 2) Server timed out the connection.
    Action:      1) Check if the server session was terminated. 2) Check if the timeout parameters are set properly in sqlnet.ora.

    Start with those two and let us know how it goes. :)
