RE: Connection Timeout/Reset by Peer while in GUI

["George Sagen" <gsagen@xxxxxxxxxxxxxxxxxxx>]

Martyn,

Connection timeouts and connections being reset by peer are more likely
networking issues or index problems, not PC hardware performance issues. I
wouldn't use resources on upgrading the PC hardware with an expectation that
timeout issues will go away, though I might do it to speed up CEA and COM in
general.

Regarding network problems with the PC connection timing out, I once saw on
6.0.02 PC's taking a long time to connect or timing out when DHCP was turned
on for internet addressing purposes. When the user wasn't connected to the
internet it would search for the DHCP server and be unable to find it.
Eventually the PC would use some other service for IP address resolution,
but BPCS would sometimes time out before that. Turn off DHCP and suddenly
everything connected fine. I also recently saw a system where the router
table on the AS/400 was incorrectly configured to look for addresses on the
wrong segments across the WAN before looking on the LAN. Slowed down the
connect time so it took over 30 seconds just to load a program (6.1 GUI).

Regarding index problems, there have been many recent discussions on this
list about how having the right indexes can speed up data access and
sometimes avert a fatal timeout by helping the programs avoid sequential
file scans.

How can you tell if your problem is likely network or index problems? If it
takes a long time to load all your programs or they timeout before they can
load, you probably have a network problem. Also, if while in the middle of
working, you are spontaneously disconnected with no apparent pattern, you
may have duplicate IP addresses. Find out if your network uses static IP
addressing or some service that assigns addresses. If static, two or more
nodes likely have the same address. Of course you may have an evil IT weenie
randomly yanking patch cables from the hub and cackling to himself as users
across the building start swearing (I know you're reading this, Nevin).  If
your programs load okay, but some of them are just slow and eventually time
out, you probably have an index problem.

Bottom line...I wouldn't upgrade the PC's for your timeout issue.

Best wishes.

Geo.

.  We are also having time-out problems especially in order
.  entry/maintenance. Can you please tell me what upgrades you made to your
.  PC's? We currently have all PC's with 32 Mb and are considering
.  upgrading to 64Mb. in the hope that it will solve the problem. I am
.  extremely interested in your experiences.
