Sounds to me like you want use Symmetric Replication. First thing you want to do is have ALL your databases on the same page, get them running the SAME version of Oracle. Symmetric Rep is a complex animal and I don't recommend trying it or Prallel Server unless both nodes and or databases are on the EXACT SAME release.
