DB2 unable to detect dead network card on server when setting registry variable DB2TCP_CLIENT_KEEPALIVE_TIMEOUT. Since it does not detect the dead network card, this prevents automatic client re-route from starting. Problem is specific to Linux platform.

Workaround: Manually tune Linux keepalive TCP/IP kernel parms, however this will affect all applications on the system. DB2 should be able to tune keepalive values so it can quickly detect dead NIC on server side. Oracle has this capability. Linux kernel introduced TCP/IP socket parameter TCP_USER_TIMEOUT in kernel 3.10 to implement functionality for DB2 to tune these parameters at application level instead of system level.

Please add DB2 support for TCP_USER_TIMEOUT so it can detect dead NIC on server side without affecting other applications on same system.
