Several Weblogic components like EJBs, Datasources and Queues are accessed using JNDI-lookups. In default Weblogic configurations, the JNDI-Tree can be accessed without any kind of authentication. This is far from ideal, because any process, inside or outside the Weblogic container is capable of invoking these components. Only Datasources have an extra layer of security and can only be used remotely by activating the property “weblogic.jdbc.remoteEnabled”. In this blog entry I...

  A few weeks before the first ever Oracle sponsored Maker Faire, I was experimenting with some of the cognitive (vision) recognition APIs available. Google Vision API, Watson Visual Recognition and Microsoft Computer Vision API are some of the biggest players in this field right now. After testing all of them I found the idea of Microsoft’s CaptionBot really compelling: Upload an image to the CaptionBot and it will try to come up with a coherent caption based on a mashup of...

  Oracle recently made their ‘Kafka on Cloud’ service available: the Event Hub cloud service – offered as part of the Big Data Compute Cloud Service. In this article, I will briefly show the steps I went through to get up and running with this service. To be frank, it was not entirely intuitive – so this may be handy the next time I have to do it or perhaps when you are struggling. One obvious point of confusion is the overloaded use of the ‘service’ – which is applied among...

  Jeremy Ashley, Group Vice President of the Oracle Applications User Experience (OAUX) team, appears on both big and small screens as he discusses the role of user experience in our work lives in this round-up of recent videos, articles, and posts: Web Summit in Lisbon: CloudMovesTV caught up with Jeremy at the Web Summit in Lisbon, Portugal, in November for an interview about how technology is influencing the user experience, and what Oracle is doing about it. For a more...

Microservices as an architectural style as well as scalable and manageable cloud infrastructure are the foundation for modern and flexible business applications. Therefore, Oracle invested heavily in maturing its Cloud portfolio and providing services to support development and operations of such applications. One Oracle cloud service aimed at these kind of applications is “Oracle Application Container Cloud Service” (ACC). It provides a simple Docker based environment in...

  Others may disagree, but I am a fan of creating the first cut of ADF forms for Oracle BPM using the human task's auto-generation feature.  While this worked well in previous releases, in both 12.2.1.1 and 12.2.1.2 small manual edits are now required to eliminate the errors on the generated form. There are now two types of errors caused by 12.2.1 auto-generation - edAttTy errors and duplicate ID errors. edAttTy Errors The first type of error on the generated page causes...

To push an application on the Application Container Cloud Service (ACCS) from the terminal, you can use the Oracle product 'PaaS Service Manager Command Line Interface' (PSM CLI). PSM CLI is a tool to help you with scripting tasks you want to do against several Oracle Clouds. The steps to push your application to the Oracle Cloud are not that complex, in short: 1. We create a container in Storage Cloud for our application. 2. We put the application archive in the Storage...

  Recently I did a POC with BAM 12c at the customer. In a series of post’s I will describe my findings/experiences. This is the first post in the series. As a starting point we have the following situation: We have an ACM composite consisting of a case with associated BusinessRule component and different BPM processes implemented as Case Activities. See figure below. This is one single composite application. This means that there are two objects for BAM (‘VeryHugeCase Activity’...

  That's how Oracle ACE Rolando Carrasco characterizes the current state in the evolution of software development in the latest 2 Minute Tech Tip video, which also features Rolando's colleague Leonardo Gonzalez. Rolando and Leonardo cite microservices and containers as key factors in this freedom, and discuss the role Oracle Application Container Cloud Service plays in allowing developers to focus on coding. Their message is well worth two minutes of your time. Watch the video...
