I was recently working on a simple process in PCS for a license approval flow. Given the purists that I am, I began by defining definitions for the various message based activities used in the process flow. The process was an asynchronous process with a few intermediate events. A simplified snippet is shown here for visualization. In order to implement the above process, I created a service definition (WSDL) with the following schematic. As you can notice, there is a portType...

Introduction The high availability of applications in the WebLogic environment is realized by clustering. Managed servers in the cluster work together. The information about transactions is distributed cluster-wide. If a cluster member fails, another server takes over the tasks of the failed server and executes them. In this way, the applications are kept running without interruption. The AdminServer is a single point of failure: if the server fails, the Domain is no longer...

In my previous blog, I showed how to get started with Decision Model Notation (DMN) in Oracle Process Cloud Service and how to create a simple Decision Table. Picking up from there, we will now look into creating If-Then-Else rules, which should also be familiar to people who know Oracle's old Business Rules. We will also create a service and call it from a process. Creating an If Then Else Decision As Input, I have created a TotalAmount object, which is the total amount of a...

One of the new features introduced in a recent monthly update of Oracle Developer Cloud Service is the advanced code search box you can see at the top right when you look at your Git repositories. This is a separate search functionality from the regular project artifacts search the box does in the other section of DevCS. This search functionality is language aware, supporting a variety of languages including Java, JavaScript, HTML and CSS. It scans and indexes your code to...

Recently, Oracle Process Cloud Service (PCS) has made another major step forward through the addition of a whole new way of dealing with business rules. This brand new Decision Model Notation (DMN) feature is developed seperate from the actual processes and deployed as a microservice, so your decision models can be reused and everything is nicely loosely coupled. I like it.What I also like about DMN is that it's much more (business) user friendly than the rule engine from...

This blog covers CI/CD for a Java application deployed on Oracle Application Container Cloud which uses Oracle Database Cloud via its declarative Service Binding feature We will focus on setting up and configuring Oracle Developer Cloud Service to achieve end-to-end DevOps and specifically look at Continuous Deployment to Application Container Cloud Using Oracle Maven repository from Developer Cloud Service The scenario depicted here will be used as a reference Quick background He...

In a previous blog post, I wrote about the new Decision Modeling capability introduced in Oracle Process Cloud Service. The earlier post provided an introduction to DMN and a usage scenario along with a working prototype. The decision modeling and notation standard released by OMG is a very powerful framework providing an implementation and modeling specification for solving many complex operational and strategic decision in an organization. In this second blog post of...
