A note about the jTDS Drivers: Using both the JtdsDataSource and the DBCP BasicDataSource seem to result in client connection starvation on Windows. The JtdsDataSource is better behaved, though, i.e. it doesn’t throw an exception. There is mileage in upping the maximum number of client ports and dropping the Tcp wait delay down to 30 seconds. Use RegEdit to add the following values:
