A South American stock exchange that used a trading system built with HPE NonStop servers faced high data entry error rates and the resulting manual reconciliation process required to correct these errors prevented it from complying with its same-day or next-day clearing commitments. Working with its clearinghouse, the exchange chose the Shadowbase replication engine to re-architect its system to eliminate manual data re-entry. 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 HPE NonStop trading system. The exchange also utilizes Shadowbase heterogeneous replication in managing 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 HPE 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 HPE 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.
