Middleware is where applications meet infrastructure. Here our consultants write about WebLogic, JBoss EAP, WildFly and Tomcat in real production environments: installing and clustering them, patching, deploying applications and finding out why something stopped working.
Oracle WebLogic Server continues to be a backbone for enterprise Java applications. With version 14, it brings improved Java compatibility, stronger security defaults, and better clustering. But while the platform is robust, monitoring it effectively remains a challenge. Introduction Within WebLogic 14, out-of-the-box tools such as the Remote Console and WLST scripts provide some visibility, but they are limited when…
One of the most impactful (and often underestimated) differences between JBoss EAP 7.4 and JBoss EAP 8 is how credentials are handled. This is not just a documentation tweak or a recommendation shift. It is a hard security enforcement change driven by modern platform standards and compliance expectations from Red Hat. If you remember only one thing from this article,…
I have been asked to migrate a customer environment from WildFly 26 to WildFly 38. That’s a meaningful upgrade, not just a version bump, because WildFly 38 represents the latest stable baseline with modern Jakarta EE support, updated security, and long-term compatibility with modern Java runtimes like OpenJDK 17… Before we dive into commands and configurations, let’s anchor this in…
The arrival of JBoss EAP 8 marks a significant milestone in the evolution of Red Hat’s Enterprise Application Server. For many organizations still running on JBoss EAP 7.x, the upgrade brings not only new features but also strategic changes aligned with the modernization of the Java ecosystem.Let’s explore what really changed and what you need to know before moving forward.…
After years working with WebLogic and other application servers (JBoss, WildFly, Tomcat, etc.), I’ve seen most of the challenges enterprises face: domains that refuse to start, clusters that behave unpredictably, and performance issues caused by poor configurations. What experience has taught me is clear: when Best Practices are applied, environments are far more stable and easier to manage. With the…
This short blog is to share with you an issue we faced at a customer during Oracle Fusion Middleware 14 installation. Introduction and Symptoms An important step in the installation process is the Oracle Fusion Middleware Metadata repository creation using the RCU (Repository Creation Utility) which creates the necessary schemas for the components. But when running the Repository Creation Utility…
During an upgrade project to Documentum 23.4, I faced yet again another interesting behavior from D2. The Documentum Server upgrade happened properly for all components like the Connection Broker, Repositories, D2, etc… The OTDS was also setup and available/working properly without too much trouble. However, the deployment of the D2 war file was a bit of another story. As usual,…
As you might know, Documentum “deprecated” (in reality disabled completely) the different Authentication Plugins that were bundled with a Documentum Server. That means that with recent versions of Documentum, you cannot login to your LDAP-managed account anymore without having configured an OTDS and integrated it with your Documentum Server. After you installed the OTDS, and configured it to work with…
A bit more than 6 years ago (already), I wrote a series of blogs about the silent install of some standard Documentum component. It included things from the binaries, the Docbroker (Connection Broker), the Repositories (both Primary and Remote), D2 and finally xPlore (binaries, Dsearch and IndexAgent). As of today, the principle is still the same for these components. Of…
In this blog we will be looking at the configuration of M-Files Ment Integration into an M-Files vault. We will discuss the configuration, the benefits and learn how to work with it.This is a follow-up to the webinar I hosted on 10 December and is aimed at technical teams responsible for configuration, implementation and end-user training. Overview The latest version…
If you are familiar with Java, you probably know that starting with JDK 9, you may need to add some “–add-exports” or “–add-opens” parameters to the JAVA_TOOL_OPTIONS. This is the Strong Encapsulation, which started with JDK 9 and was only displaying warnings until JDK 16. With Java 17, however, it is now fully in effect so you may start seeing…
In the previous blogs, I explained the difference between Credential Store and Password Vault (Credential Store vs Password Vault), and I share how to secure your sensitive strings with Password Vault. Today, one more blog to give the whole view, how to use Credential Store in JBoss EAP! What is the Credential Store? Introduced with the elytron subsystem, credential stores…
