I don't want to use session reliability because that will keep the application
open on the users PC if the network connection is broken for any reason. The
end users will be traders using trading systems with figures constantly being
updated on the screen while they trade. If the system lost connectivity and
they thought it was still working, they could be loosing a lot of money.
What we want is to use the keep alives to know when the network connection is
broken, then if it is, the user cannot see the application but is still open on
the server for 15 minutes. Then if before the 15 minute period happens they can
connect back in, they can then finish their trades. This is the way the traders
want this particular application to behave.
We have another system for traders using CPS4 that will disconnect and reset
the session once 60 seconds is elapsed. This works fine. But this is not the
case for the scenario outlined above.
Thanks,
Chris

Sorry to be blunt, but that doesn't make sense. That is not what Session
Reliability is. SR does not reset/logoff session, it simple reconnects to a
session (in the background) if there is a break in connectivity (a nurse
pushing a cart on the floor, she hits a temporary dead spot and regains
connectivy. The end user doesn't see anything other than a short pause). SR
is different than ICA Keepalive... ICA keepalive is just that, sending a ICA
ping through the network to keep the network equipment from idling and dropping
the connection. This can happen if the user session sits idle (user is not
doing anything for a length of time).
So based on the business driver you just described, ICA KA is not what you
want. SR is. If you need to deal with idle or disconnected session, simply
set the upper limits you want.

No, I've turned off session reliability on the Farm and on the WI. We
don't want to keep the applications open if they are not connect because they
are getting live trading information.

You're look at the wrong setting... What you're asking for is session
reliability, not ICA keepalives. Make sure the firewall is able to pass port
2598 from the CSG box to you Presentation Servers. On presentation servers,
make sure that the disconnect timeout value is what you want it to be as well
as the Reset on Disconnect option is not set.

I've got an issue where I want run the ICA keepalives to 15
minutes. After this I've set the sessions to reset. This works fine through the
PN or a WI with a direct connection.
I've got an issue where when users connect through a pair of
load balanced (Cisco load balanced) CSG servers to their WI page and when they
get disconnected (I pull the network cable) there session gets reset after 1
minute. As I said before, if I go through the same WI server with a direct
connection the session does get disconnected after the 15 minutes.
It seems like the CSG has changed the ICA keepalive settings
from the Citrix Farm and using it's own. I've done various searches and have
tried different things but can't get this working to the 15 minutes through the
CSG servers. I'm running PS4, CSG3 and WI4.2
Any ideas?
Thanks,
Chris
