The releases, which deliver advances in performance and availability, reflect CA's continuing commitment to its mainframe databases, which are used by prominent organisations, such as BT and State Street Corporation, to support mission-critical applications.

As organisations extend their Internet-based and mobile computing infrastructure, they continue to rely on high performance, high availability databases that support some of the largest systems in the world, says Mark Combs, senior vice-president at CA.

The latest CA-IDMS release features an express reorg utility for z/OS that aims to improve system availability by reducing scheduled downtime. The release also provides enhanced compliance and audit reporting capabilities that enable organisations to track database activity by user ID, Combs adds.

Beta test users include BT, local, national and international telecommunications services, and higher-value broadband products and services to customers in Europe, the Americas and Asia-Pacific.

BT uses CA-IDMS to support its 12 terabyte Customer Service System (CSS) database that processes more than 240m customer billing, order processing and fault reporting transactions daily for more 20m business and residential customers, says Alan Fretten, COO for mainframe technical services at BT.
