How to use the SAME transaction in a distributed environment

Hi All,
I'm looking for a possible solution to the following problem:

1. My application consists of 2 separate processes (lets call them A and B), running on 2 separate machines (using CORBA as middleware)
2. Both A & B are using the SAME Oracle-DB instance (probably the same schema too - but not necessarily)
3. The tables are separate (A has its own tables, and so does B)
4. I want to implement kind of a "distributed" transaction:
5. A will start a transaction, do it's INSERTs, and then "pass" the transaction to B.
6. B will do it's INSERTs, on the transaction it got from A
7. The COMMIT can be done either by A (after B finishes) or by B.

Does Oracle have any solution for this issue? (I'm using Oracle 9i, C++, and OTL)

Thanks, merry Christmas and a VERY happy new year...

Allon.
