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!

Hello Lutz,
If I correctly understand this is legal to use licensed Oracle SE1 on 2-node cluster consisting of double CPU Intel servers with licensed OEL and Oracle Clusterware (for free) installed?
from licensing
Thanks, Igor
Hi Igor,
no, you understood wrong!
It is SE not SE1 which includes the two node cluster license.
SE1 is cheeper and only for one node and does not include the clsuterware license.

I believe that Igor has this correct. SE always included the clusterware; at least since it had RAC for free.
This means that you can now get free clusterware for a series of SE1 2 CPU boxes. That does not preclude the servers from having SE1 licenses though. Before this yo would have had to upgrade to or buy SE licenses, now you can do the same with SE1.
By the way I work with a group that provides free license planning and assessments so if you want any well researched advice contact me and we’ll make sure you know the parameters.
At last, I found the right place to read some quite interesting stuff, thanks for sharing.
