Thanks everyone. http://www.samag.com/documents/s=1323/sam0110e/0110e.htm ------------------------- http://www.rvs.uni-hannover.de/people/voeckler/tune/EN/tune.html -------------------------- Try a netstat -i to see if you have any interface errors. Check to see if there are errors or a duplex speed mismatch by checking these settings on the switch that you are connected to. The error your getting is a TCP error but if the lower levels of networking aren't configured proeprly it could cause timeots and a hit on performance. By correcting speed/duplex mismatches on my switch i got our sites down from 5 second pageloads to 1.25 and collectively they get more than 1 million hits a month. ----------------------- There are some tuning hints for websphere on Solaris at: http://www-3.ibm.com/software/webservers/appserv/doc/v30/se/as3stmsb.html#Head er_67 I would definitely consider exploring setting your device to hard-coded 100 full-duplex if possible. Talk with your network administrator to make sure you are plugged into a switch which is capable of full-duplex mode, then run through the following: # ndd -set /dev/hme adv_10fdx_cap 0 <-- don't use 10 full duplex # ndd -set /dev/hme adv_10hdx_cap 0 <-- don't use 10 half duplex # ndd -set /dev/hme adv_100hdx_cap 0 <-- don't use 100 half duplex # ndd -set /dev/hme adv_100fdx_cap 1 <-- DO use 100 full duplex # ndd -set /dev/hme adv_autoneg_cap 0 <-- don't use auto-negotiation Note that the last ndd above will cause the hme interface to reset, causing a temporary network outage. You'll also want to make sure that the interface on the switch is hard-set to 100/full as well, auto-negotiation is bad on either end. Also, did you make sure to set the tcp_conn_req_max_q on system startup? Parameters set with ndd will not persist across reboot, they must be set on startup every time (typically via an initialization script under /etc/rc*.d). _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Mon Jun 3 08:12:51 2002
