0 What good is an application if its just lying there on your laptop ? It needs to deployed to a place where it can be used — in the modern era, ‘this place’ is the Cloud In addition to deploying it to the cloud easily, you should also be iterate over the development process to ensure the path from your local development environment to the cloud is hassle free and seamless — continuous integration and deployment can help us achieve this In this blog, we will take an existing Java...

When working on a PCS application, you save and publish your changes often. However, when you publish a certain state of the application, you can decide to create a snapshot of this state of the application. This can be very helpful if the publish represents a certain version of the application. Later these snapshots can be deployed or reverted to in case you want to roll back to a previous version. It is also possible to see what was in the application at the time of the...

In a previous blog we have made notices that it is not possible to create a Webform based on a xsd-type that contains a list elements. In our case a list of pizza ingredients. In this post we will give an alternative way to create a webform that displays the data, including the list of ingredients. For this we have created a new form IngredientsWebForm. As we tried before, It does not work to drop the full business object on the canvas. Therefore, we have now made up the form...

About Application Container Cloud Service ACCS provides a pre-configured platform (Platform as a Service or PAAS) where you can quickly deploy and host your applications.  For many of today’s applications, the hosting server is just that, a place to host the application.  Most of the time the only thing an application needs from the server is to have it support the application’s programming language and to provide in and out connections through ports.  Using a PAAS such as...

To create simple Human Tasks we use web forms in Process Cloud Service (PCS). Within the Delivery Process of the Jarvis Pizzeria, we are going to implement the HT for ‘Try Contacting the Customer’. This human task should become available after we have checked that the Customer is not a member and we do not know his email address.  Try contacting the non-regular / member from Jarvis Pizzeria, in the swimlane of the CallCenter. We will take the Design First approach, meaning we...

About six month ago I enjoyed the developer experience Oracle provided with his cloud portfolio. In my opinion the majority of services was integrated seamlessly. Especially the integration between Oracle Developer Cloud Service, a complete CI/CD as a service solution, in combination with various other infrastructure and platform services met my needs perfectly. Unfortunately, I experienced some problems since Oracle switched to its new Oracle Cloud Infrastructure (OCI). I...

  So far we have covered most standard components of the PCS suite. However, we haven’t looked at the “Notification Task” in-depth yet. We have used the on-premises variant at various projects but it was the hassle of setting up the User Messaging Service (UMS) that made you reluctant to use this feature on beforehand. Will the PCS variant be a gamechanger? Let’s find out! We implemented a basic process with a standard notification task and configured it to send an email to marc...

Oracle today announced that it is open sourcing the Fn project Kubernetes Installer and Global Multi-Cluster Management, two projects designed to help developers build the next generation of container native applications leveraging Kubernetes. Both projects are integrated with the Oracle Container Native Application Development Platform, providing developers with an integrated and enterprise-grade platform to build, deploy and operate applications. The Fn project Installer...
