First time poster, but we've been using c3p0 for a while. We're using
c3p0-0.9.1.2 with Oracle and a typically 8 node cluster of appservers.
A year or so ago we actually switched from dbcp because of major
Now, we are starting to see issues with our database pooling load,
receiving large numbers of timeouts after connections ramp up, and often
they don't seem to go away very quickly. If anyone has information to
share or links about using c3p0 under very heavy load it'd be much
I can certainly post more detailed information (in the act of putting it
together), but I'm also trying to assess the health of c3p0 and
0.9.1.2. There hasn't been much activity for a while and there is a
slow trickle on the email list, which seems Ok for a smallish stable
open source library. But seeing the repeated bug reports of deadlock
and other connection issues has me a little worried, and it seems worthy
of investigating whether c3p0 may be the cause of some of these issues (
in addition to our application ).
Any ideas or thoughts greatly welcomed.
