Your error message means that you get database locks on the ADSM
database. I have no idea why, is it possible to put a sniffer on your
FDDI ring ? Otherwise I recommend to forward this problem to IBM and
check if they can help you.

                Master TJ:

                The CommTimeOut is set at 600 (10 minutes).  Sometimes
this is not long enough for reestablishing communications.  Often they
do reconnect and restart the session before the time is up.  Increasing
this setting might allow a complete backup most of the time, but I would
still like to solve the base problem.

                Gerry,

                Do you have the COMMTimeout parameter in the server
option file, if yes
                let me know the value.

                Regards Tj

                                Dear TJ,

                                Both the AIX ADSM server and the NetWare
client are on
                the FDDI ring--no routers.  In fact, the NetWare clients
that are on
                ethernet and have to traverse a switch have no problem.

                                I am still wondering what the ADSM error
messages mean.

                                If you can not ping during your session
lost, that sound
                like a network
                                problem and not a ADSM problem.
Recommend to track down
                your network
                                connections and check if you have any
routers between
                the client and the
                                server is yes look to the routers log
file.

                                Regards Tj
                                Riscmanagament

                                When I query actlog, if the interruption
goes long
                enough so that the
                                session is terminated, I get the
following:
                                ANR0481W Session 1485 for node FTC-IS
(Netware)
                terminated - client did not
                                respond in 600 seconds.

                                Otherwise, nothing.  Where else might I
look?

                                I am attempting to backup NetWare 4.11.
We have a FDDI
                backbone to which
                                the
                                AIX ADSM server attaches directly.
NetWare boxes which
                use an Ethernet
                                connection have no problem.  However,
NetWare boxes with
                FDDI cards lose
                                connection to the AIX ADSM server during
a backup.  The
                interruption can
                                last
                                several minutes, after which another
connection is
                usually established.

                                This happens repeatedly during the
incremental.  The
                ADSM error log on the
                                NW
                                server gives the following message,
apparantly for each
                time the connection
                                is
                                lost:

                reestablished.

                                During the disconnection hiatus, you
can't ping from
                either the NetWare
                                client
                                to the AIX server or from the AIX to the
NetWare client
                it can't, but each
                                can
                                ping other addresses.

                                I have tried manipulating the
TCPWINDOWSIZE,
                TCPBUFFSIZE, and
                                LARGECOMMBUFFERS
                                parameters to solve the problem, to no
avail.

                                Anybody run into this problem before?
What do these
                error messages mean?
