Oracle Database 12c, is now available for download from Oracle Technology Network (OTN), introducing a new multitenant architecture that simplifies the process of consolidating databases onto the cloud, enabling customers to manage many databases as one without changing their applications.
The foundation of Oracle Public Cloud Services, Oracle Database 12c can greatly benefit customers deploying private database clouds and Software-as-a-Service (SaaS) vendors looking for the power of Oracle Database in a secure multitenant model.
Oracle Database 12c, optimized on SPARC and Intel Xeon processors, is a major release. It introduces 500 additional features and is the result of 2,500 person-years of development and 1.2 million hours of testing, plus an extensive beta program with Oracle’s customers and partners. The software is also co-engineered with Oracle’s SPARC T5 servers.
Oracle Database 12c addresses the key challenges of customers who are consolidating databases in a private cloud model by enabling greatly improved efficiency and lower management costs, while retaining the autonomy of separate databases.
The new Oracle Multitenant feature of Oracle Database 12c allows each database plugged into the new multitenant architecture to look and feel like a standard Oracle Database to applications allowing existing applications to run unchanged. The company says that by supporting multi-tenancy in the database tier, rather than the application tier, Oracle Multitenant makes all ISV applications that run on the Oracle Database ready for SaaS.
Oracle Multitenant manages many databases as one and can increase server resource utilization and reduce the time and effort required for database upgrades, backup, recovery, and much more. The multitenant architecture provides virtually instantaneous provisioning and cloning of databases, which makes it an ideal platform for database test and development clouds.
Oracle Multitenant works with all Oracle Database features, including Real Application Clusters, Partitioning, Data Guard, Compression, Automatic Storage Management, Real Application Testing, Transparent Data Encryption, Database Vault, and more.
Oracle Database 12c also introduces new Automatic Data Optimization features. A Heat Map monitors database read/write activity enabling Database Administrators to easily identify the data that is hot (very active), warm (read-only) and cold (rarely read) stored in tables and partitions.
Using smart compression and storage tiering, Database Administrators can easily define server managed policies to automatically compress and tier OLTP, Data Warehouse and Archive data based on the activity and age of data.
Oracle Database 12c includes more security innovations than any other previous Oracle database release, helping customers address evolving threats and stringent data privacy regulations. New redaction capabilities allow organizations to protect sensitive data such as credit card numbers displayed in applications - without changes to most applications. Sensitive data is redacted at run-time based on pre-defined policies and account session information.
Oracle Database 12c also includes new Run-Time Privilege Analysis, enabling organizations to identify privileges and roles actually being used, helping revoke unnecessary privileges and enforce least privilege with confidence that business operations will not be disrupted.
The new version introduces several high availability features, as well as enhancements to existing technologies that enable continuous access to enterprise data. Global Data Services offers load balancing and failover to globally distributed database configurations while Data Guard Far Sync extends zero-data-loss standby protection to any distance, not limited by latency.
