Clustering is an OS thing. If the OS supports clustering of the two boxes, then
Oracle can run in a clustered configuration.

Still doesn't tell me what form of redundancy. Machine failure and disaster
recovery are two completely different requirements. You can't use a single
cluster to provide both.

Active-active means users are connected to the database from both nodes of the
cluster. In Oracle terms, that requires OPS in 8i, or RAC in 9i.
Active-standby means only one node of the cluster is used for active database
connections. The second node will be failed over to if there are problems with
the first one. This is what Oracle FailSafe does in Oracle terms.

HTH. Additions and corrections welcome.
