iBATIS & DB connections

[Broderick, Andrew (GE Indust, ES Rail, consultant)]

Hi,

I am using iBATIS 2.3 with Spring 2 and Oracle 10g. I have a few questions:

-Does iBATIS get a new Connection for each query and then close it again 
afterwards? 
-Is it different for select vs insert or update? 
-Does it depend on whether a transaction is open?

Thanks,

Andrew B
