Based on your business needs, Cornerstone can recommend and implement Oracle technologies to maximize your data availability and fault tolerance.

Oracle Real Application Clusters (RAC) is a shared or fused cache architecture that offers linear scalability and high availability. A shared database is leveraged by multiple servers allowing the most effective load balancing of system resources.

Oracle RAC can be implemented for either the Enterprise Edition or Standard Edition Oracle Database. Standard Edition offers RAC out of the box included with the Standard License for up to four CPU sockets. This provides a highly competitive solution for organizations seeking an active/active clustered solution.

Oracle Data Guard in combination with Oracle RAC delivers a disaster recovery solution that is the most advanced in the industry. Data Guard provides for the deployment of Physical / Logical / Active standby databases. These standby databases can be hosted locally or across a wide distance of separation from the primary production database site, thus providing data protection in the event of loss of primary site. Additionally with Oracle 11g Active Data Guard and 10g/11g Logical Data Guards, data warehousing sourcing can be achieved by leveraging the standby database(s) for reporting / ETL /ELT or any other OLAP/BI solutions.

Oracle GoldenGate is a comprehensive software package for enabling the replication of data in heterogeneous data environments. The product set enables high availability solutions, real-time data integration, transactional change data capture, data replication, transformations, and verification between operational and analytical enterprise systems.
