How to make Two-Way Replication Setup.

Hi,

I need setup like :

Consider, Master - A and Slave - B machine.

We do operations on master will replicate to Slave. But in case if

Case 1:

If master(A) goes down then slave (B) become a master. So changes on slave(B - which is now master) needs to replicate to master (A) when master (A) gets up.

Case 2.

If master(A) down and then up then it again will become a master and B becomes slave.

Is ORACLE database supports this kind of mechanism? If Yes, How ?

Or Any other database support ?
