We are using OraDirect .NET 3.50.10 in our .Net application and Oracle 9.2.0.4. .Net code that works with Oracle DB is state inside .DLL that we are calling through another .EXE. We are working in Direct mode and Unicode = true. We reading output cursors by OracleDataReader. Sometimes on closing application I am recieving error:
System.ObjectDisposedException was unhandled
Message="Safe handle has been closed"
Source="System"
ObjectName=""
StackTrace:
at System.Net.UnsafeNclNativeMethods.OSSOCK.getsockopt(SafeCloseSocket socketHandle, SocketOptionLevel optionLevel, SocketOptionName optionName, Int32& optionValue, Int32& optionLength)

The problem occurs occationally and hard reprodusable. Do you have any idea what is the reason of this exception?

Some details: reading output stored procedure cursors implemented like this:
GlobalData.DataBaseAccess.oraConnection.Open();
GlobalData.DataBaseAccess.getDescriptiveCommand.ExecuteNonQuery();
CoreLab.Oracle.OracleDataReader dataReader =
((OracleCursor)getDescriptiveCommand.Parameters ["cursorName"].OracleValue).GetDataReader();
while (dataReader.Read())
{
}
dataReader.Close();

May be the problem is somewhere here? When I am commenting this code the exception is disappear.

We are investigating this problem.
You will be notified on results as soon as possible.

This problem is fixed in OraDirect 3.55.15.

Hi,
