Does this occur if you use JDBC? You can use the Adobe driver
if you have enterprise or use Oracle's own. If you must use ODBC,
try the jadazoom driver instead of sequellink. See this technote -
Lots of Oracle ODBC issues have cleared up by using the
latest Oracle Client for your version of Oracle or even a new
client. IE use the 10.x instant client to connect to a pre-10
Oracle server. Update the client and ODBC driver itself.
