the jdbc driver isn't happy
can you check your alert logs and see if there's a problem being reported in the db that would cause the connection to drop?
we may also need to enable tracing and generate some jdbc logs to see that's going on
ords 19.2 is using a 19c driver and you're connected to a 18c database, so there shouldn't be any real conflict of note
my suggestion is to do a bit of detective work to figure out why the connection drop is happening so we can fix that - and no, i i know of no way to suppress those messages
Nothing in the Alert Log. It's very clean.
I will try to reproduce an example.
