Oracle has released Oracle NoSQL Database llg Release 2, a highly scalable, low-latency, key-value database for real-time big data workloads. A key component of the Oracle Big Data platform, Oracle NoSQL Database llg Release 2 enables organizations to easily manage high-velocity transactional data generated by Web-based applications, social media, sensors, smart meters, and communications services (white paper available).
Oracle continues to drive innovation with its unmatched technology portfolio, encompassing all aspects of data management. Oracle NoSQL Database llg Release 2 provides developers with that ‘last mile’ infrastructure to enable crucial real-time interaction between an organization’s applications and its customers. It provides a key mechanism for enterprises to maximize the value of big data.
Data is stored as key-value pairs, which are written to particular storage node(s), based on the hashed value of the primary key. Storage nodes are replicated to ensure high availability, rapid failover in the event of a node failure and optimal load balancing of queries. Customer applications are written using an easy-to-use Java/C API to read and write data.
Oracle NoSQL Driver links with the customer application, providing access to the data via appropriate storage node for the requested key. A web based console as well as command line interface is available for easy administration of the cluster. Network topology and latency aware Oracle NoSQL Database Driver working in conjunction with highly scalable, fault tolerant, high throughput storage engine enables a more granular distribution of resources and processing, which reduces the incidence of hot spots and provides greater performance on commodity based hardware.

Oracle has unveiled the StorageTek Virtual Library Extension, the industry’s first highly scalable second tier of disk storage that optimizes tape processing in mainframe environments. The StorageTek Virtual Library Extension expands the disk capacity of the StorageTek Virtual Storage Manager virtual tape environment to enable a secondary tier of disk-based performance while maintaining streamlined management. This addition provides as much as 3.5 PB of additional effective disk storage space, giving customers more-seamless disk buffer scalability to manage growth and increase performance while reducing costs.
The integrated StorageTek Virtual Storage Manager/StorageTek Virtual Library Extension environment is the only mainframe virtual tape solution to provide a single, policy-based management interface that migrates data between high-performance disk, high-capacity disk, and tape tiers.
The StorageTek Virtual Library Extension maximizes data protection and availability by leveraging the unique StorageTek Virtual Storage Manager architecture that enables data to be dynamically stored and protected in multiple tiers of storage and at multiple locations without involving the mainframe. The product uses Oracle Solaris ZFS technology to provide higher reliability with triple-parity RAID-Z3, which delivers five times more data reliability than IBM systems using RAID-6.
“Oracle continues to address the needs of mainframe virtual tape customers, ” says Robert, research director of data protection and recovery at International Data Corporation (IDC). “Oracle’s StorageTek Virtual Library Extension provides an innovative and cost-effective approach by adding a second tier of disk to its StorageTek Virtual Storage Manager products.”
