Does Oracle Clusterware or Oracle Real Application Clusters support heterogeneous platforms?
Oracle Clusterware and Oracle Real Application Clusters do not support heterogeneous platforms in the same cluster. Enterprise Manager Grid Control supports heterogeneous platforms. We do support machines of different speeds and size in the same cluster. All nodes must run the same operating system (I.E. they must be binary compatible). In an active data-sharing environment, like Oracle RAC, we do not support machines having different chip architectures.
