Oracle 12C Architecture ____oracle

July 8, 2013, Oracle China announced that the company's new generation of database oracle12c officially listed, and can be downloaded through the Oracle Technology Network (OTN). The product was released by CEO Larry Ellison at Oracle's global convention as early as October 1, 2012, and after 9 months of waiting, users can finally use Oracle's most heavyweight products.

Compared with Oracle's previous generations of databases--oracle 8i, 9i, 10g, 11g, the Oracle 12c named "C" is a clear database designed for cloud computing (Cloud). According to the information disclosed by Oracle Company, Oracle 12c has added more than 500 new features, with new features covering six areas: a new multi-tenant architecture for cloud database consolidation, automatic data optimization, deep security protection, maximum availability for database cloud, efficient database management, and simplified large data analysis. These features can be high speed, high scalability, high reliability and high security database platform, to provide customers with a new multi-tenant architecture, the user database to cloud migration can improve the quality of enterprise applications and application performance, but also reduce the hundreds of database as a management, Improve the flexibility and effectiveness of the overall operation in the process of helping the enterprise move towards the cloud.

Oracle has also disclosed that Oracle 12c has been optimized for the company's SPARC processors and Intel Xeon processors, after years of research and development for over 2,500 people, as well as the results of more than 12 million hours of testing, as well as a large number of test projects by Oracle customers and partners. In addition, Oracle database 12c is also integrated with Oracle SPARC T5 servers. As a foundation for Oracle's Public cloud services, Oracle 12c provides more benefits for customers to deploy private database clouds, and SaaS vendors gain the higher value of Oracle databases in secure multi-tenant models.

Andy Mendelsohn, senior vice president of Oracle Database server technology and chief architect Tom Kyte, will introduce the latest product in a webcast on July 10 9:00 (US Pacific Time). Oracle will also have a more detailed description of Oracle 12c database at the Oracle Global Conference in Shanghai on July 21 ~ 24th, when ZDNet will also conduct video interviews with Andy Mendelsohn on Oracle 12c in Shanghai.

Oracle 12c features that Oracle first disclosed:

A new multi-tenant architecture for cloud Database consolidation

As a new feature of Oracle 12c, Oracle Multi-Tenant technology can insert any database into a multi-tenant architecture, as well as inserting any standard Oracle database into the application without any impact on the operation of existing applications. Oracle 12c retains its own functionality for decentralized databases and enables database consolidation within the private cloud model. By supporting multiple tenants at the database level rather than at the application tier, Oracle Multi-Tenant technology enables the application of all independent software developers (ISVs) to run smoothly on Oracle databases prepared for SaaS. Oracle multi-tenant Technology realizes the integration management of multiple databases, improves the utilization of server resources and saves the time and work required for database upgrade, backup and recovery. The multi-tenant architecture provides almost instantaneous configuration and database replication, making the architecture an ideal platform for database testing and development cloud. Oracle Multi-Tenant Technology works with all Oracle database features, including true application clustering, partitioning, data protection, compression, automated storage management, true application testing, transparent data encryption, database vault, and so on.

Automatic data optimization

To help customers manage more data effectively, reduce storage costs, and improve database performance, Oracle 12c has added the latest Automatic data optimization features. Thermal map Monitoring Database read/write functionality makes it easy for database administrators to identify how active data is stored in tables and partitions, whether it's hot (very active), warm data (read-only), or cold data (rarely read). With intelligent compression and storage tiering capabilities, database administrators can easily define server management policies to automate compression and tiered OLTP, data warehousing, and archived data based on data availability and time to use.

Deep security Protection

Oracle 12c has introduced more security innovations than previous versions of Oracle databases to help customers cope with escalating security threats and stringent data privacy compliance requirements. New editing features enable organizations to protect sensitive data without changing most applications, such as credit card numbers displayed in the application. Sensitive data can be proofread at run time based on predefined policies and client-side information. Oracle 12c also includes the latest runtime priority analysis to enable organizations to determine the rights and roles that are actually used, to help the enterprise revoke unnecessary permissions while fully enforcing the required permissions, and to ensure that business operations are not affected.

Maximum availability for database-oriented cloud

Oracle 12c adds several high-availability features and enhances existing technologies to enable uninterrupted access to enterprise data. Global Data Services provide load balancing and failover capabilities for distributed database configurations worldwide. Data protection remote synchronization is not limited to latency and extends to any distance of 0 data loss of standby protection. The application of Oracle is continuously perfected, and failure processing is automatically restarted to overwrite the end user's application.

Efficient database Management

The seamless integration of Oracle Enterprise Manager 12c Cloud control enables administrators to easily implement and manage new Oracle database 12c features, including new multi-tenant architectures and data revisions. By simultaneously testing and extending the true task load, Oracle truly applies the comprehensive testing capabilities of the test to help customers verify upgrades and policy consolidation.

Simplifying Large data analysis

Oracle database 12c enhances MapReduce capabilities in large data-oriented databases through SQL pattern matching. These features enable direct and scalable presentation of business event sequences, such as financial transactions, blog entries, and click-Stream logs. With the latest database prediction algorithm and the high integration of open source R with Oracle database 12c, data experts can better analyze enterprise information and large data.
