Oracle <-> PostgreSQL
I have been asked to look at linking an 11gR2-on-64bit-Linux database to a PostgreSQL 8.4 database (also running on 64-bit Linux), and vice versa. I really don't have much clue where to start, and Google hasn't been of much help.
Am I right in thinking that the "Oracle Database Gateways 11g Release 2 (11.2.0.1.0) for Linux x86-64" is my starting point for making Oracle 'talk to' PostgreSQL? If so, can anyone point me to the relevant doco. I couldn't even find that!
And will the Gateway let the PostgreSQL database select from the Oracle database? Or do I need to do something else to enable that?
Sorry for the clueless-ness. I don't have much idea where to start on this. Any pointers appreciated.
