Oracle Technology Network announces that “Oracle Unbreakable Linux support customers at the Basic and Premier support levels now can download and deploy Oracle Clusterware at no additional license fee or support cost.”
Before this the clusterware needed at least one Standard Edition License.
Now you can download the clusterware and use it as an extension of your Linux to make virtually any application highly available even without having an Oracle Database Server.
For more info on this and ready made scripts see my previouse post on how to protect a single instance database with the clusterware.
This is really cool!
