Having played around with all the features PCS has to offer it is now time to see some action. In this blog we will show you how to deploy your application, start the application and see how it behaves within the workspace. But first of all, we need to have a application that is ready to deploy. In other words, our minimal deployable product consists of an application without any errors. Pressing the validate button in the top-right corner will tell you the current state of...

  This blog demonstrates Worker Applications on Oracle Cloud with the help of an example which makes of 1. Redis as a job queue (deployed on Oracle Cloud Infrastructure Classic), and 2. a Java based service which acts as a asynchronous processor (a.k.a Worker) deployed to Oracle Application Container Cloud Worker applications ? Traditionally, any service deployed to Oracle Application Container Cloud was was required to bind to $PORT and was given a public URL. But this is...

In the post  Import the 12c On-premises Preparation Process we saw the Business Types that were imported (also shown here) We already stated that we had an issue with enumerations. But is this the only issue with the xsd? Unfortunately not, as will become clear soon. Making task forms was not part of the import blog, however, in this blog we are going to do this. We will do this based on the imported xsd. So let’s get started. Read the complete article here. PaaS...

A fairly common combination of Oracle Public Cloud services that I use together – for example for the implementation of microservices – is DBaaS, Application Container Cloud, Application [Container] Cache and Event Hub. In this article, I show the sequence of steps I went through in the Oracle Public Cloud console a few days back to prepare a demo environment for my presentations at Devoxx Morocco in Casablanca. Alternatively, I could have used the command line psm tool and a...

Within PCS there are actually two different environments, a development environment and the production environment. Once you have deployed your application it is available in the production environment as a certain version of the application. However, you might want to test your application before you deploy a new version. You can also test your environment against the so called ‘development environment’. The blue button bar has a Test as well as an Deploy button on the top...

NB This is a guest post by one of our awesome interns Rae Jeffries-Harris, describing part of the work she did with our Bristol team over the summer. Thanks Rae. JAX-RS on FaaS? A lot of Java programmers are familiar with building RESTful web applications using frameworks such as Jersey which adhere to the JAX-RSspecification. JAX-RS abstracts much of the low-level detail away from the programmer, so that tasks such as client-server communication become less fiddly. But you...

  As we are very optimistic developer we started out with modeling and testing the happy flow of our Jarvis pizzeria. But as experience learns it is the big bad world that obliges us to deal with both expected and unexpected failures. This blog post we will look into the handling of SOAP faults that PCS has to offer out-of-the-box. As a starting point we have created a basic process with one service call: This SOAP Fault service is connected to mockable.io service that is...

Introduction Over the last couple of years our work on various microservices platforms in the cloud has brought us into close collaboration and engagement with many customers and as a result we have developed a deep understanding of what developers struggle with when adopting microservices architectures in addition to a deep knowledge of distributed systems. A major motivation for joining Oracle, besides working with a great team of very smart people from startups, Amazon and...

This post should provide some help for those working for the first time with SOA CS in the Oracle Cloud. After working a lot with ACCS, OCCS, Developer CS, and JCS, surprisingly I struggled with the provisioning of SOA CS in the Oracle Cloud. Part of the problem was that the storage service seems to be accessed in (at least) three different ways within OPC . The syntax StorageName-IDDomain/chosenContainerName workes fine for DB and Java CS. There also you can create the...
