Designed for organizations that run online transaction processing (OLTP) applications on distributed systems, IBM® DB2® pureScale™ offers clustering technology that helps deliver high availability and exceptional scalability transparent to applications. DB2 pureScale is based on technology from IBM DB2 for z/OS® and is available as an option on IBM DB2 9.7 Enterprise Server Edition.
DB2 pureScale reduces the risk and cost of business growth by providing unlimited capacity, continuous availability, and application transparency.
Unlimited Capacity
DB2 pureScale provides practically unlimited capacity for any transactional workload. Scaling your system is simply a matter of connecting a new node and issuing two simple commands. DB2 pureScale’s cluster-based, shared-disk architecture reduces costs through efficient use of system resources.
Application Transparency
With DB2 pureScale, you don’t need to change your application code to efficiently run on multiple nodes. Thanks to a proven, scalable architecture, you can grow your application to meet the most demanding business requirements. You can also run applications written for other database software with little or no changes; DB2 offers native support for commonly used syntax and PL/SQL procedure language, making it easier than ever to move from Oracle database to DB2.
Continuous Availability
DB2 pureScale provides continuous availability through the use of highly reliable clustering technology on IBM systems and a redundant architecture.
