I know that Oracle support for Phalcon 2 is not finished yet.
@phalcon: Would it be possible to use oci8 driver instead of pdo_oci for Oracle adapter?
It was really annoying to get pdo_oci running on a debian 7.5 server with php 5.6. Oci8 driver on the other hand was available after 10 minutes ;-)
Oci8 is activly maintained by the community and Oracle.
