Opted to build an in-memory application grid for its resilience and risk-free scale-out, selecting Oracle Coherence in-memory data grid and Oracle JRockit Java virtual machine (JVM) to achieve consistent low latency for credit checks
Achieved the less than five millisecond latency target for 99.9% of credit checks with Oracle JRockit, which features deterministic garbage collection for predictable pause times
Chose Oracle Coherence for its performance, in-memory characteristics and compatibility with JRockit
Preferred Coherence for its simplicity, which enabled a team of four to deliver the system quickly and support it globally
Fully prototyped the system in three months on a server cluster running an Oracle Coherence data grid and Oracle JRockit, using distributed caches to store intraday data and process credit check requests
Installed regional system instances to ensure proximity to clients and enable low latency and instant failover
Used diagnostics in Oracle JRockit Mission Control to pinpoint performance bottlenecks and direct improvements
Benefited from expert guidance, technical support, objective feedback, and help from Oracle’s UK presales teams
