BT Group plc is one of the world’s leading communications solutions and services providers, with operations in 170 countries. It delivers fixed-line, broadband, and mobile services, as well as TV products and networked IT services.
BT developed an application to automate its network inventory planning and service provisioning. This application is crucial to BT’s operations, automating inventory planning for the organization’s next generation internet protocol (IP)-based convergent network infrastructure, known as 21st Century Network (21CN). It is also critical to enabling BT to deliver next-generation services to its customers―from IP-based voice communications, to digital television, music, and internet content, to mobile Ethernet and fast broadband.
BT’s network inventory planning and service provisioning application, which handles 40,000 transactions per minute, is key to providing end-to-end services to customers. It stores the entire organization’s network inventory information, such as circuits, routers, switches, and locations, it and is a single source of truth for other interfacing components, such as network event monitoring systems, business intelligence systems, and data warehouses. As this application is so crucial to BT’s customer delivery, any system outages could severely impact BT’s service delivery and troubleshooting capabilities. Therefore, it was difficult for BT to find suitable time slots for planned maintenance, and it often delayed lengthy activities, such as platform refreshes.
BT had a key business requirement to migrate the network inventory planning and service provisioning application from the HP-Tru64 operating system to Oracle Linux with minimal downtime. Previously, the system would have been down for 20 hours to complete this migration. Instead, BT chose Oracle GoldenGate to ensure a smooth migration, which it completed within less than two hours. Since the migration, BT has used Oracle GoldenGate and Oracle Data Integrator Enterprise Edtion within the new architecture to significantly improve the system’s overall performance.
“We considered other options such as Oracle Streams, Oracle Logical Standby Database, and QUEST Shareplex,” said Vipul Patel, platform designer, BT. “After a detailed analysis, we concluded that using Oracle GoldenGate to smoothly migrate to a new environment with minimal outage on the production system was the best option available. We completed the migration in less than two hours.”
