Currently, the time between keepalive messages being sent on idle connections is based off the socket sweeper timer value (SOCKSWP in SNAKEY). This socket sweeper value is defined in increments of minutes. Waiting minutes before determining that the remote side is unavailable is too long. SOLUTION: A new SNAKEY macro parameter, TCPALIVE, has been created for the time interval between keepalive messages. This new parameter is defined in seconds. By specifying a value for TCPALIVE in the SNAKEY macro, a TCP keepalive message will be sent for any idle TCP connection that was created with the SO_KEEPALIVE option set in the socket. DEPENDENCIES SEGMENTS TO BE ASSEMBLED OR COMPILED: ctk2.asm SEGMENTS TO BE LINK EDITED: None. COREQS: None. MIGRATION CONSIDERATIONS: Installing this APAR causes the new keepalive timer value to default to the value of the socket sweeper, converted to seconds. To use a value that is different from this, the TCPALIVE parameter needs to be coded in the SNAKEY macro. DOWNLOAD INSTRUCTIONS: http://www.ibm.com/software/htp/tpf/pages/maint -- END APAR PJ28996
