Hi,
I've got a feeling that this has been discussed before, but I couldn't find
any entries going back through the list for 4 months or so.
We are starting to implement ADSM for our Novell servers. To date we
haven't had a lot of success. First, some information about our
environment.
Server is 2.1.5.12 running on AIX 4.1.4
Communcations is entirely TCP/IP
The network (for the Novell servers) is 10mbit ethernet
Client version is 2.1.0.6
We have two problems:
We our getting extremely poor performance, in the order of 200mb/hour.
As a comparison, we are getting in excess of 1gb/hour from some NT
servers (admittedly faster CPU, disks, etc.). We have checked the things
mentioned in the Performance Tuning Guide. The only thing that we have
changed as a result of that was the TCP/IP MTU size (from 512 to 4000).
The MTU was already set in excess of 4000 on the Novell servers. The
volumes on these servers have 10-20 thousand files.
We are getting a number of TCP/IP failures as show below:
27-03-1997 03:43:45 TcpFlush: Error 60 sending data on Tcp/Ip socket
39358524.
27-03-1997 03:43:45 sessSendVerb: Error sending Verb, rc: -50
27-03-1997 03:43:45 TcpFlush: Error 32 sending data on Tcp/Ip socket
39358524.
27-03-1997 03:43:45 TcpFlush: Error 4 sending data on Tcp/Ip socket
4294967295.
27-03-1997 03:43:45 sessSendVerb: Error sending Verb, rc: -50
27-03-1997 03:43:46 ANS4017E Session rejected: TCP/IP connection failure
27-03-1997 03:43:46 ANS4847E Scheduled event 'BACKUP' failed. Return code
= 1.
Any clues?
