A South American stock exchange using a trading system built with HP NonStop servers faced high data entry error rates. The resulting manual reconciliation process required to correct these errors prevented it from complying with its trade settlement commitments. Working with its clearinghouse, the exchange chose the Shadowbase data replication engine to re-architect its system to eliminate manual data re-entry, thereby eliminating the errors and enabling the stock exchange to meet its settlement commitments. The re-architected system uses Shadowbase software to replicate a Sybase validation database from the clearinghouse’s AIX system to a NonStop SQL/MP database located on the exchange’s HP NonStop trading system. The exchange also utilizes Shadowbase heterogeneous replication to update several Linux/MySQL data warehouses that provide trading history. The exchange replaced an earlier micro-batch updating approach with Shadowbase real-time transactional data replication from the HP NonStop SQL/MP trading database to the MySQL databases. The exchange also implemented Shadowbase solutions for disaster recovery protection of its trading system (providing active/passive data replication between the primary and standby HP NonStop servers). Shadowbase software now plays a major role in integrating the many systems in the exchange’s IT infrastructure, as well as providing continuous availability for its mission-critical business services.
