As more and more people start to take a closer look at Oracle Database 12c, I believe more will start to see the usefulness in many of the new features. However, at the same time many of the older features that everyone has come to love will be discontinued. Two such features are the Advanced Replication and Oracle Streams options within Oracle. As of Oracle Database 12c (220.127.116.11), Oracle is making a fundamental switch to newer technology within their stack of products. As of the release of 12c, Advanced Replication and Oracle Streams are being discontinued. Moving forward, Oracle Golden Gate is going to replace all features of Advanced Replication and Oracle Streams!
These features include (listed in documentation):
1. Multi-master replication
2. Updateable Materalized Views
3. Hierarchical Materialized Views
4. Deployment Templates.
I for one am looking forward to this change. When I first read this in the beta documentation (confirmed in GA docs) and starting looking through the data dictionary views, I got really excited. Oracle has decided to switch to a very useful tool that was mostly used for migration purposes. In my opinion, a change like this is showing that Oracle has committed to the Golden Gate product and has confidence in it moving forward.
In Oracle’s commitment to Golden Gate, many of you will notice that Oracle has created views to help monitor the Golden Gate process within the Oracle Database 12c. I noticed this during beta testing (being a Golden Gate guy) started to look for docs on how it was going to work. At this point, I haven’t found any docs on the integration between Oracle Database 12c and Golden Gate in the database docs.
This is something that I’m defiantly excited about trying out and see how this is going to work. As I find out more, I’ll be posting it here.
