In the digital era, information technology is the horse to the chariot on which businesses ride to solve problems and ultimately reach their goals. Businesses are relying on their IT systems to enable better engagement with customers, drive competitive advantage and create new revenue streams.
With this reliance comes both an opportunity and responsibility to solve problems in different ways. One of the pioneers in the research of complex systems management, Howard Eisner, has long been an advocate of Think Outside the Box (TOTB) for problem solving. In this blog, I’m going to discuss how applying these principles to the design and management of IT systems will keep your business at the front of the pack in the digital era.
In my previous blog, Optimising OSB Performance with Remote Coherence Cache, I detailed how separating out Coherence JVM from OSB JVM can enhance the performance of Oracle Service Bus (OSB). In this blog, I will demonstrate how to achieve this outcome with a step-by-step guide.
At times where there is high concurrency or large volumes of data associated with services, service architects use an in-built feature of OSB (18.104.22.168.0 +) – Result Caching – to reduce the load on systems and allow applications to scale horizontally. In this blog I’m going to outline some common issues you can run into with Result Caching and how you can apply remote Coherence cache to overcome these issues and optimise performance.
Managing the happy path in a service flow is the first priority in terms of service delivery methodology. But the real pain comes in when the faulty situation needs to be dealt with. Fault Management Framework 11g allows us to centrally manage the faults for a composite application. Service Deliveries that include multiple services can have a centralized fault management framework. This allows the service delivery to be more configuration driven, less painful in terms of managing the fault handling and declarative in nature - ‘if this happens, do this!’
