Hello *SM*ers,
since we changed our network interface on the tsm server (IBM P630,
AIX5.3)
to Gigabit Eth, we get very often the error ANR0481W, Session lost.
On the
Client Error Log we get the message ANS1809W, ANS1810E very often.
On the
server side the option for commtimeout is 3600 and idletimeout is 60.
Has anyone an idea what the problem my be? Can I increase
commtimeout to
7200 and idletimeout to 120?
Best regards

Gerd -
Your timeout values look sufficient to me - and if they were good for
processing before this change, then they probably are still good,
unto themselves.
I would suspect the network change, which may have been introduced
into the environment without adequate testing or configuration
guidance to those using it. I would pursue TCP load testing outside
of TSM, looking for anomalies in operation, as well as conferring
with your networking people.
Note that the TSM Messages manual says of ANS1809W:
"Frequent occurrences of the ANS1809W message can indicate a problem
with the network. If this message is repeatedly found in the
dsmerror.log, investigate possible networking trouble, such as a
failing network interface card or router problem. One common problem
is the media speed of the network adaptors: If the network adaptors
are set to ′′auto-negotiate′′, try changing them to ′′100%
fullduplex ′′."
[Note that with gige, you may be forced to use autonegotiation rather
than fixed settings; but perform quality assurance tests nonetheless.]
