Thanks Jacques.

About how much data can you push over the gig network between Tivoli and one 
client.  The best I ever do is about 40 GB an hour.

Hi,

My settings for udp (send & receive) are as follow (1GIG Network):
udp_sendspace=65536
udp_recvspace=65536

The rest of the settings are the same.

Subject: [ADSM-L] archive hangs


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
