Still not enough information.

How many systems, are all of them expected to be read/write at all times  ?

Is HA cluster software (such as Sun Cluster) involved ?

Does the replication need to be synchronous (ie a transaction on A will 
fail if B can't commit it) or is asynchronous sufficient ?  If 
asynchronous what is the time window for replication ?

Is it a single master with remote copies (that are in standby) ?

What network/storage infrastructure is available ?
