Author: Ricardo Ferreira Introduction Messaging is one of those technologies that have been around for decades, but only recently people got aware of the important role that messaging plays to any software-based architecture. Any use case that requires messages to be exchanged between systems in a reliable, fault-tolerant and scalable way may leverage messaging to fulfill its needs. Nowadays we have thousands of messaging products available to use, so deciding which one to...

Introduction Federation is a well-known pattern and has been discussed at length on this blog. Almost every vendor or cloud provider out there supports Federation and it’s been around for quite some time now. In this blog post, I will talk about Federation again, but this time in combination with Weblogic's Virtual Users and Groups. What that means, in practical terms, is that users and groups won’t have to be synchronized between the Identity Provider (Oracle Identity Cloud...

Executive Overview With the current release of SOA Cloud Service (SOACS) a common requirement often requested is to connect to an on-premise database from the cloud SOACS instance. This article outlines a quick and simple method to establish the connectivity between the single-node SOACS instance and the on-premise database server using an SSH tunnel. Solution Approach Overview The overall solution is described in the diagram shown below. An SSH tunnel is established between...

Introduction: To communicate with any process, you need to know at least 3 things about it - IP address, port number and protocol. Fusion Applications comprises many running processes. End users communicate directly with only a handful of them, but all processes communicate with other processes to provide necessary services. Understanding various IP addresses and listen ports is very important to effectively troubleshoot communication between various components and...

Introduction Many WebLogic Server (WLS) implementations use JRockit 28 as the JVM implementation. JRockit 28 comes with the very useful JRockit Flight Recorder which helps in many troubleshooting situations. Problem In high volume WLS implementations with many domains and many managed servers the Flight Recorder could fill up the disk of the temporary file storage (often located at /tmp). This works good for some time, but suddenly results in failures during restarts of some...

Recently, I worked with a customer where we would notice severe performance degradation over time within JCS (Java Cloud Service). The product used was Oracle Service Bus (OSB) where it would take around 2 seconds to process a request and send a response. Over time, we would see the same request/response take over 1 minute! If we restarted the JVM and tested again, the response time was back to 2 seconds but would again degrade over time. In an effort to troubleshoot this,...

Author: Ricardo Ferreira Introduction One of the most popular use cases for Oracle Service Bus (OSB) is the mediation of synchronous service interactions. In this scenario, a client invokes the service through a proxy instead of the actual service endpoint, guaranteeing that the consumer is decoupled from the producer. This type of architecture allows producers to be changed without impacting the consumers, allowing greater agility for projects with volatile requirements....
