In an attempt to tune our system (AIX 5.3, TSM 5.2.7) we changed the following AIX parameters and now several archive jobs tend to just die and hangout until they timeout.
sb_max = 2097152 tcp_sendspace = 262144 tcp_recvspace = 262144 udp_sendspace = 131072 udp_recvspace = 131072 rfc1323= 1 We made these changes trying get to better throughput on our gig network. (we are now working on 2 problems at once). The gig nics are set to auto_negotiate since AIX does not have a 1000/full setting. The network folks say everything is clean from their end. I would like to resolve the hung condition first and then continue to address the gig speed issues. Does anyone have some ideas. I can remove the options I changed but on face value I believe they should be set like this. Any and all help is appreciated. Have a nice day everyone. Ralph
