Well there is a feature called RAC (Real Application Clusters) that is available for Oracle9i and later versions. This allows you to replicate. This is available with both the standard & enterprise editions but not with standard edition one. If you need more details about this option, you can go to:

If you join the Oracle Technology Network you can access a lot of information about RAC.
