jTDS Drivers

Here's an example of the configuration for the jTDS drivers:

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:

Name

Type

Key

Value

Description

TcpTimedWaitDelay

DWORD

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\TCPIP\Parameters

30 (Decimal)

Reduces the time a connection spends in TIME_WAIT to 30 seconds

MaxUserPort

DWORD

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\TCPIP\Parameters

32768 (Decimal)

Increases the number of ports a client application can use to 32768
