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...

  Internet of Things (IOT) is the internetworking of physical devices, vehicles (also referred to as “connected devices” and “smart devices“), buildings, and other items-embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data.(source Wikipedia). If you have not watched movie I.T, must watch it today and you will get to the feelings of Smart-Home concept and how heavily used IOT is showing in the...

Databases play a critical role in most software project architecture. However it seems that the concepts of agile methodology, version management, and continuous delivery are somehow less mature in the world of DBAs and database developers. In this article we'll show you how to bring modern development techniques to the world of database objects and logic leveraging Oracle Developer Cloud Service. Managing SQL Scripts Lifecycle Database objects are defined through a set of SQL...

Oracle Stream Analytics (OSA) is a graphical tool that provides “Business Insight into Fast Data”. In layman terms, that translates into an intuitive web-based interface for exploring, analysing, and manipulating streaming data sources in realtime. These sources can include REST, JMS queues, as well as Kafka. The inclusion of Kafka opens OSA up to integration with many new-build data pipelines that use this as a backbone technology. Previously known as Oracle Stream Explorer,...

  You've read a bunch of online tutorials and you've managed to containerize your application. You have even exposed a port so you can reach the application from the outside world, but when you connect, you're greeted with an error page: "Cannot connect to the database". It's time to start debugging! Below you will find some methods for debugging containers, as well as some information about the crashcart tool we have developed at Oracle to make debugging easier.

Simple use case……you want to connect to a customer system over the internet. The customers system has an API but requires 2-way SSL. This means we have to send a client certificate along to make sure the SSL handshake can be completed. If your server has already a server certificate installed, it will send this one along by default but the customers system won’t accept it as it is different then what it trusts. In the next section, I will explain how to add a client...

TL;DR I will show you that the MedRec sample application for WebLogic can be used for deploying Java artifacts and configuring WebLogic resources on first boot of a WebLogic Docker image. We can do this with a 5 line Dockerfile and a medrec.py script which customises the WebLogic domain. This example is available to play with on Github at this link. In previous blogs, we showed how to run WebLogic with Java Applications on Docker both locally and on Oracle Container Cloud...

  Oracle SOA Database Adapters provide a polling mechanism that will periodically query a table to see if a there is a new or changed record.  If so, it can trigger a BPEL process.  This is enormously useful.  However, on one client I ran into a series of issues with database pollers in a clustered environment when they … collided.  (queue dramatic music) The issue began one quiet morning early in the project after I started my WebLogic Admin Server and 2 SOA 11g...

In an earlier article, I discussed the creation of a generic Docker Container Image that runs any Node.JS application based on sources for that application on GitHub. When the container is started, the GitHub URL is passed in as a parameter and the container will download the sources and run the application. Using this generic image, you can your Node application everywhere you can run a Docker container. One of the places where you can run a Docker Container is the Oracle...
