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...

  The Oracle SOA Suite infrastructure, especially composites, use the database intensively. Not only are the process definitions stored in the database, also a lot of audit information gets written there. The SOA infrastructure database, if not well managed, will grow and will eventually have detrimental effects on performance. In this blog post I will give some quick suggestions that will help you increase performance of your SOA Suite infrastructure on the database side by...

Two of my favorite Oracle Cloud services are the Exadata Express Cloud Service (Exadata Express) and the Application Container Cloud Service (ACCS). Exadata Express is a fully managed Oracle Database service at an entry-level price point for small to medium sized data and ACCS is an easy way to deploy apps in Docker containers. In this post, I’ll demonstrate how to connect these two services at the most basic level.What do I mean by “the most basic level”? First, I’m not...

As part of the #PaaSForum community presentation we created on stage an application to handle a dynamic process to adopt a Bunny for a day. The case has two stages to adopt a bunny and take care of the bunny. The milestone “happy bunny” is achieved when to you feed and play with the bunny. Want to try it yourself? Get a feed Oracle Process Cloud Services trial here (for OPN members please see here). Happy Easter from the PaaS Community – Jürgen Kress SOA & BPM Partner Community F...
