You have my total sympathy. I'm hoping you get some magical replies so
and if you do I'll be saving those replies myself. You might try turning on
tracing on the client. I believe (haven't tried this myself) that if you
have a sqlnet.ora file on the client, you can set trace_level_client to turn
on tracing. The reason that server side tracing often doesn't help much is
that from the perspective of the server the client just never showed up
again.
Other things to consider are just randomly changing stuff (one thing at a
time) like Oracle client version.
The other thing you should consider is to start preparing others for the
fact that you may never solve this problem, or certainly won't solve it
easily. Press the Microsoft developers for whatever they can do.

Subject: ORA-03113 (See http://ORA-03113.ora-code.com) end of file on communication channel
Any help would be appreciated.
Oracle 8.1.7 on Windows 2000 Server.
We have a complex process here, written in VB. It takes about 4 hours to
run. Last week it crashed with ORA-03113 (See http://ORA-03113.ora-code.com) showing on the user's screen, but
no trace or log files. It's crashed twice today, again with no files
generated. This is a major process and I'm under pressure to come up with a
solution. I've googled, and checked Metalink, but the error is so general
that without an error file I don't know where to start, other than blindly
applying "solutions" and hoping one works. I tried tracing the session, but
I ended up with 5Mb of FETCH/EXEC in a cursor loop within seconds. There is
a lot of VB code, cursors and temporary tables used, and it's politically
difficult to re-write. Anyone have any idea where I can start looking for
the problem?
