ORA-12571, ORA-03114 and other connection errors.

[Paul Green]

What might cause the following behavior?
We have a set of front-end programs accessing an Oracle database on
the server.
Things work fine on our older computers and mostly OK on our new
computers - except one particular program, after being used for a few
minutes gives errors like ORA-12571, ORA-03114.
This suggests the network is disconnected, but tnsping shows the
Oracle DB is still there, and the other programs in the suite still
work.

So, I think my question is, what sort of setup options on the new
computer might cause this sort of thing to happen? The new computer
has got Windows 2000 with service pack 4.

The fault is an intermittent one in the sense that how long it takes
to happen seems to vary, but once it has happened, the program won't
work at all until the program is closed and started again.

Any help very welcome!

Did you have any founding, as I got the same problem now.

End users are regularly experiencing the ORA-03114 not connected to database error while performing update actions in their application.
