Today, Oracle announced the availability of Oracle® TimesTen In-Memory Database 11g and Oracle In-Memory Database Cache 11g, the database caching option for Oracle Database 11g.
- This latest release features major enhancements including performance and scale-out through the Database Cache Grid; support for PL/SQL, Oracle Call Interface (OCI), and Pro*C embedded SQL Programming language; and rock solid reliability and high availability through automated failover via integration with Oracle Clusterware and Oracle Data Guard.
These new product capabilities further enable enterprises to benefit from the extreme performance that in-memory database caching in the middle-tier offers.
Oracle In-Memory Database Cache is fully integrated with the Oracle infrastructure software stack including Oracle Database, Oracle Real Application Clusters, Oracle Enterprise Manager, Oracle SQL Developer, and components of Oracle Fusion Middleware.
Oracle TimesTen In-Memory Database is a stand-alone in-memory relational database with full persistence and recoverability. Oracle In-Memory Database Cache is the pre-integrated SQL cache database option for the Oracle Database. Both products are designed for deployment in the middle-tier.
Improved Performance for Mission-Critical Applications
- Oracle In-Memory Database Cache provides applications with extreme performance by caching data in memory for fast and consistent response times. The in-memory caches are transactional read-write caches with full persistence, recoverability, and automatic data synchronization with the Oracle Database.
New features include:
- Database Cache Grid: enables incremental scale-out of in-memory database caching with online addition/removal of cache grid nodes without service interruption. It also provides data location transparency so that applications need not know where the data resides; each cache grid node can access data from its local memory, from another cache grid node, or from the backend Oracle Database. Database Cache Grid provides transactional consistency across cache nodes with high availability and data synchronization with the backend Oracle database.
PL/SQL, OCI, and Pro*C Support: simplifies the use of the Oracle In-Memory Database Cache by existing Oracle Database applications to improve application response time and throughput.
Cross-Tier High Availability: delivers improved high availability out-of-the-box, with automated failover of the in-memory databases and applications. Integration with Oracle Clusterware and Oracle Data Guard achieves near zero-downtime with virtually no data loss in case of failure.
