Many thanks to Eric Voisard and Sam Nelson for sharing their expertise. Eric provided insight to another variable tcp_time_wait_interval, that it can have an affect on connections. Sam , very graciously provided a script that he uses to tune and sanitize the tcp stack Below is the original message With Eric and Sam's replays Thanks again for the info Rich -----Original Message----- From: Rich Bonfoey Sent: Thursday, March 31, 2005 9:55 AM To: Sun Managers (sunmanagers@sunmanagers.org) Subject: TCP_keepalive Greetings Have any of you, had much dealings with the tcp_keepalive ? On Solaris 8 and 9 the value is 7200000 or 2 hours. What are some of the pit falls if this value was lowered to about 10 minutes. I have read the RFC but was looking for people who have had real experience with tweaking this value. Part of the reason for tweaking, is we have a large number of PC and OS 10 users connecting to several different systems and they have been having performance issues. Our dba decided to bring in a consultant ( that's another story ) and they said this value should be 5 minutes. I am not quite buying it, as I have read that there are multiple opinion on the correct use of tcp_keepalive.
