Oracle 12c R1: A Better Database Performance Experience
Oracle 12c R1 is the latest version of the Oracle database management system. This release of Oracle offers improved performance and new features for database administrators and developers. The improvements in Oracle 12c R1 are related to scaling, performance, and security. In this article, we will take a closer look at the new features and enhancements of Oracle 12c R1.
Improved Database Performance
Oracle 12c R1 has several performance improvements, including a new multithreaded architecture that allows for better scaling of both CPU and I/O resources. This means that the database can now take advantage of more CPUs and faster storage devices to deliver faster query response times. Additionally, with the new In-Memory Column Store feature, querying large tables has become significantly faster. Queries that used to take minutes or even hours can now be executed in just seconds.
Enhanced Security
Oracle 12c R1 has new security features that help protect the database from internal and external attacks. For example, the new privilege analysis tool can identify overprivileged users who have excessive permissions in the database. This tool can also recommend changes to user privileges to improve security. Another security feature is the new data masking tool, which can obfuscate sensitive data in the database to protect it from unauthorized access. The new encryption features also make it easier to encrypt data at rest and in transit, further enhancing data security.
New features for Developers
Oracle 12c R1 introduces several new features that simplify database development. For example, the new JSON support makes it easier to store and manipulate JSON data within the database. Additionally, the new online patching feature allows DBAs to apply patches while the database is running, thus avoiding downtime. This feature also simplifies the process of rolling back patches if necessary. Furthermore, the new pluggable database architecture allows multiple databases to share the same resources, reducing the cost of hardware and administration.
How to Upgrade to Oracle 12c R1
Upgrading to Oracle 12c R1 is relatively easy, but it requires careful planning and testing. Oracle provides several tools and guides that help customers prepare for the upgrade. These tools include the Oracle Database 12c Upgrade Assistant, which automates many of the upgrade tasks. Additionally, Oracle offers an Upgrade Compatibility Matrix, which provides information about the compatibility of different versions of Oracle databases and their associated software.
Conclusion
Oracle 12c R1 offers significant performance improvements, enhanced security, and new features for database developers. It is a recommended upgrade for customers who are currently using an older version of Oracle. The upgrade process requires careful planning and testing, but with the help of Oracle’s tools and guides, it can be a relatively strghtforward process. By upgrading to Oracle 12c R1, customers can take advantage of the latest improvements and ensure that their databases are secure, scalable, and performant.
