Hi,
With jdbc pool, is each socket connection in the pool handled by a separate
thread?
Say you have 20 connections set to be open at minimum, does that mean there
will be 20 threads? If not, then there is a degree of serialization then
right?
and
password (just in case it is reading from the wrong file somehow??).

It would be easier if all databases were hosted by a single instance
of MySQL -- then you could use Tomcat-pool's feature of being able to
provide credentials when obtaining connections from the pool -- and
get the right database. That way, a much smaller number of connections

If you have a server with 15 GB of ram (or any large number for arguments

Or can a single instance utilize all the server resources just
