There are thin XA, thin non-XA, thick (OCI) XA and non-XA drivers for
Oracle (and from multiple vendors) so you can choose whichever suits
your situation best.
The only issue with the thin drivers is that they do not support RAC/TAF
so if fail over is an issue then the OCI drivers are the way to go.

Thin drivers are easier for deployment since you don't have to have the
Oracle client libraries installed in order to connect to the DB but in
my experience they are not very well performing when used in XA
transactions (5-10 times slower than OCI drivers that we've tried).
