The xcom.glb parameter TXPI_RECEIVE_TIMEOUT allows you to set the time (in seconds) after a TCP/IP failure is detected before a socket error is generated. This parameter defaults to zero and should remain at zero unless it becomes necessary for a broken connection to generate a retryable error.
A value of zero disables the TXPI_RECEIVE_TIMEOUT.
Change this parameter from zero to 20, for example, to invoke the TCP/IP function, "select". This allows XCOM to detect a broken connection, but sacrifices some performance. Recycle xcomd after changing a value in xcom.glb
Note: In older releases this parameter appears in xcom.glb as TCPIP_RECEIVE_TIMEOUT Either parameter name will work.
