With free clustering for Unbreakable Linux, Oracle goes after Red Hat (SearchEnterpriseLinux)

AFAIK, Oracle is not supporting Red Hat Clusters.
It is providing free access to Oracle Clusterware for Red Hat users (used to be free only for
Oracle's Enterprise Linux users or those who paid for Oracle products).
Oracle Clusterware is a closed-source clusterware that runs on linux, unix, windows etc. This
is the clusterware bundled with Oracle's database active-active cluster ("RAC").
