A word from VocaLink

  • “Oracle is key to the success of our new mobile payments infrastructure, giving us a very high level of confidence in our ability to offer the required levels of availability, performance, and security. Only Oracle could provide us with such seamless continuity throughout the technology stack." – Chris Dunne, Payment Services Director, VocaLink

  • Develop the infrastructure to build, pilot, and operate a new mobile payments service on behalf of the Payments Council—the governing body for UK payment transactions
  • Enable all banks in the UK to collaborate on a centralized infrastructure to offer customers secure mobile payment services between individuals to and from any UK bank account without needing to disclose account details
  • Ensure that the service provides maximum availability, stability, security, and performance as expected by UK banks and their customers


  • Won the contract from the Payments Council to deliver a new mobile payments infrastructure, drawing on a solid track record of technical knowledge, operational expertise, and proven Oracle technologies for delivering UK payment services for more than 40 years
  • Developed a highly secure, always available service using a comprehensive Oracle technology stack, including Oracle Database with Real Application Clusters, Oracle GoldenGate, Oracle WebLogic Server, and Oracle’s SPARC T4-1 servers
  • Ensured essential high availability for mobile payments service with no single point of failure within the Oracle stack, using clustering, two separate data centers, and multiple database instances connected via Oracle GoldenGate to ensure 100% availability, 24/7, in real time
