Business Editors

Common, Fall 2001

MINNEAPOLIS--(BUSINESS WIRE)--Oct. 22, 2001

DataMirror Corporation (Nasdaq: DMCX; TSE: DMC), a leading provider of integration and resiliency solutions and an IBM high availability business partner, today announced an update to its High Availability Suite(TM) solution for IBM iSeries business environments. The update includes enhanced monitoring capabilities and performance enhancements that are designed to help customers dramatically reduce latency for system mirroring to achieve even higher levels of availability and resiliency for their critical data assets.

"DataMirror High Availability Suite already leads the industry with advanced features and functionality including exclusive XtremeCache(TM) technology, IFS mirroring support and a unique, high performance match/merge architecture," said Glen Sakuth, Director of Development, DataMirror Corporation. "The new features in this latest update further High Availability Suite's already superior mirroring performance for virtually bulletproof data protection. Customers who implement DataMirror resiliency technology realize a rapid return on their investment through increased productivity, lower operational costs and the peace of mind that they have a proven disaster avoidance and recovery solution in place."

DataMirror announced its latest update of High Availability Suite at the Fall COMMON IT Education Conference & Expo in Minneapolis, MN. COMMON is the world's largest membership of IT professionals who use IBM and IBM-compatible information technology.

New Features and Real-world Customer Benefits

Data area and data queue journalling support for V5R1 - This new functionality ensures synchronization and reduces the volume of data that must be sent from the primary system to the recovery system. This maximizes performance and reduces system overhead and latency. With OS/400 V5R1 changes to data areas and data queues are journalled and High Availability Suite will mirror in real-time only the changes to the data areas and data queues rather than the entire object, resulting in an overall throughput improvement. In any data-intensive environment, performance equals availability. The faster a solution can mirror critical data from the primary iSeries system to the recovery system, the lower the risk of latency and data loss.

Advanced monitoring capabilities - High Availability Suite now includes a simple monitor to provide administrators with a critical measure of latency in the resiliency environment through a single view. Latency that exceeds a pre-determined threshold is highlighted and an alert is generated so that administrators can rapidly take action. Administrators can quickly analyze and troubleshoot latencies so that critical line-of-business data is always available. The new monitoring capabilities provide enhanced views and readily available information for more efficient administration and greater peace of mind.

High Availability Suite unlocks the experience of now(TM) by empowering IBM iSeries customers with continuous access to the data they need to do business and get their jobs done in real-time.
