Oracle has shared nothing clusters. They're called "MySQL Clusters". As for HA in shared nothing architecture, it's always achieved by replication, it cannot be achieved by any other way because there is no sharing in shared nothing cluster. Oracle supports several types of replication: advanced replication (trigger based), STREAMS replication, Golden Gate replication and active standby (11G).
