Hi Darren,

I don't believe that the keep-alive value in RSE preferences panel affects
the connection with the IBM i.

There are keep alive parameters in the remote systems preferences. I
assume its not as easy as adjusting these, otherwise you would have
mentioned those.

Hi John,

I'm going from memory as I don't have the traces of the problem any more
but there is one connection that goes between the workspace and the job on
the i servicing the workspace. This can go for long periods without any
traffic when the user is not actively communicating with the IBM i (in a
meeting, out for lunch, etc., etc.). Most other connections, transferring
some data, running a command and the like are short-lived. So if you open
the workspace and do something with the IBM i the connection will be
started. Now if you do nothing for longer than some bridge or router or
VPN's idle time-out they seem to just "forget" the connection - no
disconnect indication is sent. Then when you go to do something RDI will
try and use the connection and find that it is broken and tell you that
the connection is lost. I've looked at disconnect issues more than once
and even engaged the Java Toolbox folks and it has always been the same
scenario. In most cases the solution has been to get the IT folks to
configure the idle time-out to be longer.

But why does this only happen with Rational Mike?

Like others I have had this problem on and off for years.

_No_ other software that I use - including two other Eclipse-based
products do it.

For me the current version of RDi 9.0.1 hasn't done it yet. But all
earlier versions did.

It is not just the VPN connection that can time-out the RSE connection.
If, for example, the VPN enters your company's intranet on one subnet
and
the IBM i is on another subnet it is likely going though some sort of
bridge or router that can also time-out connections. If you do a
network trace (using Wireshark or the like) then I think what you will
see
is a connection that the PC thinks is just fine having packets rejected
by
the router because it has timed out and discarded knowledge of the
connection which results in RSE giving you the connection lost message.

I don't know if RDi V9 is different from V7 in this respect, but I got
frustrated with disconnections when I had V7 open all day. I had my
network administrator (me) extend the timeout for port 446, 449,
8741-8476
to 8 hours when the traffic was destined for our iSeries. Obviously
actual results will vary depending on VPN technology used, networks
involved, phase of the moon, sun spots, etc.

Hi Kurt, I would be very interested in any responses. I work all the
time
through vpn and my RDi V9 sessions are constantly dropped if inactive
for
more than 10 to 15 minutes. I've gotten into the habit of stopping and
starting RDi if I've been away from the session for a while. It's
usually
faster than trying to reconnect.

But I'd be very interested if anyone has a better solution.

I wasn't heavy into RDi today, and it seemed that every time I went back

to it, it had timed out. I vaguely recall other complaints about RDi
over
VPN. Is there anything I can do to keep the connection open? I don't
recall this ever happening to me when I would work from home on bad snow

days, but it could be that I spent most of my day in RDi.
