To set 10046 for all sessions, you specify the event
clause (from below) in your init.ora. This brings it
into effect for all connections.
Note this will have a significant impact on
performance - and you'll need plenty of space in your
trace file directory.
I know in this situation its hard to change things,
but have you applied all the relevant patches to both
OS and Oracle software? Generally random drop-outs of
connections are typically more prevalent in earlier
versions of each release.
One radical thing you could try is that in my
experience, most disconnect errors occur with the cost
optimizer - you could try using rule (but this is
obviously not without considerable risk)
