Enabling Byteman Script with Red Hat JBoss Fuse and AMQ – Part 2

In my previous article, Enabling Byteman Script with Red Hat JBoss Fuse and AMQ – Part 1, we found a basic use-case for Byteman scripts with Red Hat JBoss Fuse or Red Hat JBoss AMQ. However, the log file was generated separately and only limited operations were possible. In this article I will show you how to use a Java helper class. By using Java, we get advanced operations to view or modify the content. Also, using java.util.logging allows us to log the statements to fuse.log, avoiding the creation of any other log file.

Red Hat Certification: for developers too!

Red Hat’s certification program provides validation of IT professionals’ skills and knowledge using our subscription products. Red Hat’s certifications carry credibility in the market because they are all earned by taking one or more hands-on, practical exams that last multiple hours. Like most programs offered by technology vendors, our most familiar certifications are those for system administrators.

What is less known is that Red Hat offers certifications for developers too!

Red Hat’s product portfolio goes beyond infrastructure and includes developer tools like JBoss Fuse, BRMS (Business Rules Management System), Data Virtualization, and Data Grid. These are tools used by developers to build and integrate applications more efficiently and effectively. We focus on developers when it comes to the certifications we offer in support of these products. Let’s not forget Red Hat JBoss Enterprise Application Platform, for which we offer certifications for both developers and system administrators.

It’s Time To Accelerate Your Application Development With Red Hat JBoss Middleware And Microsoft Azure

The role of applications has changed dramatically. In the past, applications were running businesses, but primarily relegated to the background. They were critical, but more operational in the sense that they kept businesses running, more or less. Today, organizations can use applications as a competitive advantage. In fact, a well-developed, well-timed application can disrupt an entire industry. Just take a look at the hotel, taxi, and movie rental industries respectively.

Containerizing SQL DB changes with Flyway, Kubernetes, and OpenShift

In DevOps projects, you are sometimes haunted by the practices inherited from the monolithic world. In a previous project, we were checking how to simply apply SQL updates and changes to a relational database management system (RDBMS) database in an OpenShift Cluster.

Micro database schema evolution patterns are perfectly described by Edson Yanaga in his brilliant free book: Migrating to Microservice Databases: From Relational Monolith to Distributed Data.  A video presentation of these patterns is also available on youtube.

In this blog post series we will show a simple approach to implement the described patterns in your Continuous Integration and Continuous Delivery (CI/CD) pipelines on OpenShift. The series is split in two parts:

  • This post shows how to handle SQL update automation using Flyway, Dockerfiles, and Kubernetes on OpenShift.
  • A future post will showcase application migration patterns, including database migration stages using OpenShift Jenkins2 pipelines.

Beta Testing in the Ever-Changing World of Automation

Beta testing is fundamentally all about the testing of a product performed by real users in a real environment. There are many tags we use to refer to the testing of similar characteristics, such as User Acceptance Testing (UAT), Customer Acceptance Testing (CAT), Customer Validation, and Field Testing (more popular in Europe). Whichever tag we use for these testing cases, the basic components are more or less the same. To discover and fix potential issues, this involves the user and front-end user interface (UI) testing, as well as the user experience (UX) related testing. This always happens in the iteration of the software development lifecycle (SDLC) where the idea has transformed into design and has passed the development phases, while the unit and integration testing has already been completed.

JBoss Data Virtualization on OpenShift: Integrating a Remote SQL Server Database

This example shows how on OpenShift to use a custom database driver to connect to an external database, through a Virtual Database (aka VDB). For this example, we will use a Microsoft SQL Server database (believe it or not, running on a Linux container), and the latest SQL Server JDBC driver.
