Aims to enhance performance of in-memory database caching in the middle-tier
Oracle has introduced its TimesTen In-Memory Database 11g and In-Memory Database Cache 11g, the database caching option for Database 11g.
The company said that the new offering features enhancements including performance and scale-out through the Database Cache Grid; support for PL/SQL, Oracle Call Interface (OCI), and ProC embedded SQL Programming language; and reliability and availability through automated failover via integration with its Clusterware and Data Guard.
These new product capabilities are expected to enable enterprises to benefit from the performance that in-memory database caching in the middle-tier offers. The company's In-Memory Database Cache is also integrated with its infrastructure software stack including its Database, Real Application Clusters, Enterprise Manager, SQL Developer, and components of Fusion Middleware.
Oracle TimesTen In-Memory Database is an in-memory relational database. The company's In-Memory Database Cache is the pre-integrated SQL cache database option for its Database. Both products are said to be designed for deployment in the middle-tier.
The company's In-Memory Database Cache reportedly allows caching data in memory for consistent response times. The in-memory caches are transactional read-write caches with persistence, recoverability and automatic data synchronisation with the company's Database.
Rex Wang, vice president of product marketing at Oracle, said: “The demand for high-performance applications continues to expand across industries. The tight integration between Oracle Database 11g and the Oracle In-Memory Database Cache option allows customers to obtain significant performance boosts to existing applications with minimal changes. And, the new Database Cache Grid capabilities enable customers to scale their middle-tier platform incrementally, as needed by their performance and capacity requirements.”
Database Cache Grid is said to enable scale-out of in-memory database caching with online addition/removal of cache grid nodes without service interruption. PL/SQL, OCI, and ProC support are expected to simplify the use of the company's In-Memory Database Cache by its existing Database applications to improve application response time and throughput. Integration with its Clusterware and Data Guard reportedly achieves near zero-downtime with virtually no data loss in case of failure.
