Getting value from IoT, Integration and Data Analytics
GitHub Copilot helped me write a Java application to process a CSV file. Not a hard task – though one that in Java always feels much harder than in Python or Node. This time round – because of Copilot – all I have to was write two simple instructions (and […]

0 It turned out to be a fairly small deal. For reference sake a brief write up of updating the Go runtime on my Ubuntu environment. Current version: go version Find latest releases of Go at https://go.dev/dl/ There is a new one. I copy the link and then run: wget https://go.dev/dl/go1.17.6.linux-amd64.tar.gz […]
0 0 Surely I would never be so stupid as to commit a file that contains sensitive information – say my Oracle Cloud account’s private key. And even if I did, I would not push that change to a public git repo on GitHub, would I? It turns out that I did […]
0 0 Gists are the code snippets that you want to retain and share – with yourself and with others. Gists can be embedded in websites, blog articles and articles on Medium. Although used for snippets, all Gists are Git repositories, so they are automatically versioned, forkable and usable from Git. A […]
0 0 Oracle Cloud Infrastructure offers the Functions service, a FaaS offering with serverless functions, based on container images built with the Project Fn FDK. In a previous article, I introduced the OCI DevOps Deployment Pipeline for Functions – a free service on OCI that automated the deployment of a Function from […]
0 0 The situation: a Compartment on OCI should be removed. Or at least all its resources should be purged. Or at least most of the resources should be removed. The challenge: there is no “purge compartment” available that will delete the resources in the compartment. Removing each resource one by one […]
0 0 This article introduces Build Pipelines and Code Repositories in OCI DevOps (released on October 26th 2021) – complementing the Artifact Registry and Deployment Pipelines that were first launched in July of 2021 and that I discussed in this article. Build [ing software] is an apparently clear indication of a specific […]
0 0 In this blog I will explain how to generate static HTML pages from your projects Pydoc (docstring) comments with Sphinx. Then we are going to host it in an Azure Web App so that everyone in your team is able to access it. Because we use a Storage Mount, when […]
0 0 It is the end of the year: time to look back, time to look forward. In the past year, I had a lot of extra time because of the Corona measures. I spent most of that time creating blog articles about AWS, starting with a series about the AWS shop […]
0 0 TL;DR: Collect debug information in an in-memory buffer that is printed to the output when an error occurs (and quietly discarded in all other cases). I may have come up with a useful idea. Or something that is not all that useful. Or even something that already exists (and I […]
0 0 Introduction In my previous blog I’ve explained what a Canonical Data Model (CDM) is and why you should use it. This blog is about how to do this. I will share my experiences on how to create and use a CDM. I gained these experiences at several projects, small ones, […]

2 0 When using Oracle Unified Directory (OUD) as an identity store, it is in some occasions needed to add OUD users to OUD groups by hand. When you have to grant privileges to one user, this is easily done through the Oracle Directory Services Manager (ODSM) interface. However doing so for […]
0 0 This blog contains tips and tricks on to how limit the JVM memory consumption of ADF applications. Like other web applications, Oracle ADF applications potentially use a lot of JVM memory. Many times, the root cause of a high memory usage is that application data retrieved from the database into memory […]
0 0 The AMIS ADF Performance Monitor is an advanced tool designed for measuring, analyzing, improving, and checking the performance of Oracle ADF applications. The monitor can track and collect crucial (production) performance information of the application’s runtime ADF components that are not standard provided by Oracle. It helps development, QA, and […]
0 0 Performance needs to be ingrained in your application – it cannot be added in during the last stages of development. In this video I discuss how you can optimize the performance of your Oracle ADF Fusion application, diagnose and solve typical performance problems, and build an efficient, responsive, scalable ADF […]
0 0 The UK Oracle User group (UKOUG) held their Tech13, technology conference 2013, in Manchester 2 weeks ago. Duncan Mills held an interesting presentation on “Adaptive Applications”.

0 0 In this post I would like to share an example how to deploy an .ear file with an Ant script to the Oracle Application Server 10.1.3 (OAS). Automatic deployment can help improve the release process. First of all because manual deployment usually costs time of the developers. Especially the lead […]
0 0 When working with scheduled tasks on a windows machine, I often wished I could work on the command line with the scheduler. As we all know, a command line interface gives us the ability to script, preventing manual repeating work. Unfortunately, until a few days ago I did not find […]

0 0 On a recent project, I ran into a problem with an XML document, that had to be enclosed within another XML document, generated from a database query. The problem I ran into was the character encoding of the XMLElement function, which eventually was worked around with UPDATEXML. In this blog […]
0 0 With the release of Soa Suite Patch Set 5 we can now try out the new UMS adapter. UMS stands for User Messaging Service but in this case it only supports email. The UMS adapter allows you to listen for new mail or send a mail from a service component. Combined with BPEL it’s […]
0 0 Last Thuesday, Mark Drake, Senior Product Manager and I, delivered a good presentation during UKOUG in Birmingham about how to use your database, via XMLDB functionality, as a file server. The presentation demonstrated as well how you could extent the “standaard” file server (aka your database) functionality with features like, […]
0 0 Some time ago… at a Oracle SOA 11g project, we had to call an external webservice which took 1 to 5 minutes to respond. The composite calling this webservice was called by another composite from a BPEL process. As you might guess, we got an timeout resulting in faulted instances. […]
0 0 A few weeks ago I had to work with a virtual box by oracle with a pre installed Database (xe) and weblogic to do some BPM Studio work. After the default installation I expected to just start the Virtual machine, start the weblogic server and enjoying the advantages of having […]
0 0 In ADF 11g Release 2, the ADF Table component has a property called ‘ActiveRowKey’. According to documentation, this represents the row that is currently active on the client. In click-to-edit mode, the active row will be made editable and is brought into view (if not already visible). Upon initial display, […]
0 0 On my way to Los Angeles (Long Beach) for KScope 2011 (12 Hours in an airplane) I had plenty of time to do some reading and writing.The book I read was an only very recently (june 2011) published ADF Book. This is not a technical deep dive into ADF, but […]
