ExpressConnect for Oracle fails when bulk copy is enabled and the bulk copy threshold is set to 1

[CR #626715] ExpressConnect for Oracle fails when you set dsi_bulk_copy to on and dsi_bulk_threshold to 1. Setting dsi_bulk_threshold to 1 not only deteriorates performance, it also suspends the Data Server Interface (DSI).

Workaround: Set dsi_bulk_threshold to 2 or higher.
