Recently I was implementing the ADF Performance Monitor at a customer site and doing a detailed performance analysis. This customer had severe (and less severe) performance problems but was unable to pinpoint the exact pain points. Frequently, end-users were complaining because they were experiencing first a very good performance (response times […]

SOA Suite 12c: Getting started in 30 minutes
This blog will get you started with the Oracle SOA Suite 12C. We will install the SOA Suite, create a Hello World BPEL project, deploy it on the integrated weblogic server and test it with the http analyzer.
Using Oracle’s Edition-Based Redefinition to support multiple SOA Suite revisions with the database adapter
When using the Oracle SOA Suite for web service development, chances are that you are also using an Oracle database and that you are at some point in need of a database adapter in one of your SOA composites. If that happens to be the case, you might also encounter […]
ADF Runtime Diagnostics: Instrumenting your ADF Application – Part 2
In a series of blog articles I show how you can instrument your ADF Application key actions. Instrumenting gives visibility and insight of what is happening inside the ADF application and in the ADF framework (what methods and queries are executed, when and how often).

WebLogic -> FMW Provisioning update
Already a year has passed since I wrote about WebLogic and Fusion Middleware provisioning with Puppet. In this year provisioning got a great boost with the popularity of DevOps and provisioning tools like Puppet, Chef or in combination with Vagrant & Oracle VirtualBox. Provisioning without tooling can be hard for companies when they […]
The road ahead for WebLogic 12c
Before we can describe all the new features of WebLogic 12.1.3 & 12.1.4 and compare this to the 12.1.2 version we should first take a look at the 10.3.6 version. WebLogic 10.3.6 is still the latest 11g version but Oracle will support 10.3.6 till 2018 and extended support till 2021. […]
OOW13: Cloud roadmap announcements – from zero to H/A WebLogic Cluster plus Database RAC in 30 minutes

Weblogic Admin and Managed servers as a Windows service
When running a Weblogic server and its managed servers I have heard at multiple projects that there is a need of automatic startup of these server processes. There is not default an options to create a windows service when installing Weblogic and for example SOA Suite. The one option that […]
Configure FMW servers with Puppet
When you have many development servers or cloud servers which runs Oracle software and then you know that configuration management of those servers is very important and must be repeatable. When you configure and install all that software by hand, then you also know that the chance is high that […]

Multiple production versions through WebLogic production redeployment
Production redeployment is a facility in WebLogic that provides the ability to temporarily have multiple versions of the same web application of web service active at the same time. Sometimes, changes in application functionality require redeployment of the application. In the theoretical case of instantaneous responses from applications, we could […]
Organizing Fusion Middleware administration in a smart and frugal way
One of the perhaps somewhat counterintuitive challenges with at least the initial stages of adopting Fusion Middleware is the fact that there is too little work in terms of administration. On the one hand, Fusion Middleware administration entails quite a bit, starting with WebLogic Server and typically extending to one […]
EJB an MDB best practices on WebLogic Cluster
Recently I did an audit on a WebLogic 11g platform of one of our customers. There were many problems with the availability of their JAVA Applications. Some of the problems we’re platform related ( installation, configuration and infrastructure related) but a lot of them already existed in an earlier stage […]
WLST script to add DataSource and DBAdapter EIS Connection Factory
Creating a EIS ConnectionFactory in your Database Adapter can be done with the WebLogic Administration Console, but of course this is also “scriptable”. What I needed was a script that created a Data Source with EIS Connection factory bound to the specific datasource. First I created a properties file, let’s […]

Timeouts in Oracle SOA Suite 11g
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. […]
Oracle Tuxedo… A renewed acquaintance
