iACS chats behind the scenes with the same host server threads that have
serviced the C and Java APIs since the 1990's.

That's what all that "authorization" noise is about.

If it won't "authorize", it's either not connecting to the host servers or
timing out on them.

I, too, have had an ACS session drop when I'm signed-on and away for
"awhile". Sometimes not.

However, what I and our staff have experienced is the inability to
sign-on -
period. I.e., after entering the user id and password to initially access
the system, we usually get the IBM i sign-on screen.

But occasionally there is a dialog box with "Sign On in Progress"
sometimes
followed by a dialog box with "Checking Authorizations". Then an error
about a firewall blockage or such (sorry, don't have any notes; I don't
remember the message id). After pushing the 'OK' button, I run the
'Connect' option again. Sometimes that works; sometimes I have had to go
through this sequence as many as seven [7] times before I get the IBM i
sign-on screen.

The service provider decided that re-IPLing the system weekly should fix
the
problem. That was done for the first time this morning at 0400. I logged
into the system at 0545. It did *not* solve the problem.

Take a look at the .HOD file you created for this user. Search on
keepalive. The default after I created a session is keepalive=false, I
would change it to true and see if it makes a difference.

Just hoping there is a simple resolution.

A user at a remote site recently received a replacement PC and we
installed iACS for 5250 access to IBMi running V7R3.

This is the only user at the site with iACS - five other users have
Client Access for Windows.

The user with iACS is the ONLY user experiencing drop outs.

The user will leave the 5250 session for a few minutes or more and
come back to a signon screen.

The option for keepalives has been ticked.

I opened a PMR with IBM and supplied comms traces from the IBMi and
iACS traces from the PC.

As this is a remote site we are using NAT which means all connections
from that site have the same source IP address and IBM is saying that
they can't interpret the trace because of this. I have suggested we
can get the source port from NETSTAT which will allow the trace to be
filtered to the required connection and have not received a reply to

this.

Has anyone else experienced this situation and been able to resolve ?

Thank you for any suggestions.
