TNS-12547 : TNS Lost Contact using ODBC / OLE DB on Windows 2000 Laptop

22042Jul 29 2004 — edited Jul 14 2006

We are experiencing application failures on Windows 2000 laptops running Oracle9i versions 9.2.0.3 and later.

The symptom is intermittent ODBC / OLE DB failures resulting from: TNS-12547: TNS:lost contact

The LISTENER.ORA has (QUEUESIZE=100) specified.

The INIT<SID>.ORA file has open_cursors=1000 and processes=250.

Any suggestions?
