Perhaps it is just my ignorance about java things, but ...
What is the difference between "database switch" and
"disconnect from one database / connect to another one" ?
Why should the later occupy more resources ?
Also, "switching connection in same connection" makes
as much sense to me as starting transaction inside transaction.
