1. there are various kind of clusters: single system image clusters
(oracle rac falls under this category); high performance cluster
(oracle claims rac is high performance);load-balancing cluster (oracle
rac does this); high availability clusters (rac is ha as well).
2. some one has to manage services (say, cluster file system, nfs,
oracle instance, interface, disks, sendmail, dns, etc). There is a way
to manage syslog across all nodes: here comes evmd of tru64 cluster or
of oracle rac.
3. If you want to manage only oracle rac instances, yes, you have no
choice but to deploy oracle clusterware. If your organization has
already deployed clusters supporting non-oracle related services, then
go with a clusterware that is certified to be compatible with oracle
clusterware.
