In OpenWorld 2016, Andy Mendelsohn announced the availability of Database 12.2 (actually 12.2.0.0.3) on the Exadata Express Cloud Service and explains the new 12.2 features and discusses the Oracle Database roadmap. The highlights are as follows:
- In Memory Database
An ADG standby now runs with the primary database. Database queries are improved 40x, 60x (JSON). The new in-memory column format are moved in Exadata Flash Cache. Non Volatile Memory is coming in 2018. - Transforming to Big Data
Tools and storage are available for big data with fast SQL access. Big data guide can extract metadata out of the JSON documents. Comprehensive data science capabilities such as machine learning, graph, spatial and multi-media analysis are ready for use. - Optimized for Cloud (Lower Cost, Agility, Elastics Scaling)
Instead of simply running databases on commodity hardwares, Oracle database is optimized for cloud with its multi-tenancy support. Oracle Database 12.2 increases the max number of PDBs per container to 4,096 PDBs with configurable isolation between private and public cloud. The PDBs within the same container now can share application objects in an Application Container including code, metadata and data. Additionally, sharing and RAC scaling out capability are available in this release.
