Last week I presented at the UKOUG’14 conference on instrumenting, analyzing, & tuning the performance of Oracle ADF applications. Instrumentation refers to an ability to monitor or measure the level of a product’s performance, to diagnose errors and to write trace information. Instrumenting gives visibility and insight of what is happening inside the […]

Securing OHS environments with latest SSL TLS protocols and SHA-2 certificates
Customer case A while ago I was contacted by a customer about their old Oracle Application and Weblogic Server environment. They were receiving complaints from users that they can’t connect to the secure site any longer. Most of the complaints came from users that just recently updated their tablet or […]
Configuring Chat in SOA Suite 12c with the XMPP driver in the UMS Adapter
Chatting or instant messaging is a valuable for of communication, somewhere between email (very asynchronous) and telephone/Skype/VoiP/HangOut (synchronous) and quite similar to SMS. Unfortunately, there is has been an explosion in the number of IM protocols and services, many of which cannot talk to each other. Whatsapp is perhaps the […]
Setup GMail as mail provider for SOA Suite 12c – configure SMTP certificate in trust store
On this subject, there are already many fine articles. I have borrowed from at least a dozen to understand what should happen and to make it work. You will find them listed under resources. It all started with me trying to have the UMS Adapter send an email. The setup […]
LDAP and Weblogic; Using ApacheDS as authentication provider for Weblogic
A Lightweight Directory Access Protocol (LDAP) server is often used to centralize management of users/groups/credentials within enterprises. An LDAP server stores user information such as group memberships and often also authorization/authentication data. You can use this information to authenticate on Weblogic Server. In this blog post I will provide a […]
ADF Performance Monitor: Measuring Slow Network Time
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 […]

new Puppet 3 Weblogic provisioning module
The last few weeks I was busy re-writing pf my puppet WLS module so it fully supports the power of Puppet 3 (thanks for more than 4000 downloads on puppet forge) . With Puppet 3 we now can use Hiera, Iterations and Lambdas expression. This does not sound like a big […]

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
Oracle’s cloud ambitions are as high as ever before. All software from Oracle should run both on premise as well as in the cloud. Moving components from on-premise to cloud or vice versa should be painless: the infrastructure in the cloud and the platform in the cloud should be the […]
ADF 12c: Using WebSockets to implement client to client push (in a scalable manner)
WebLogic 12c (12.1.2) has support for WebSockets. ADF 12c runs on WebLogic 12c. Therefore, we should be able to leverage that WebSockets support in an ADF application. And indeed we can, as this article describes. It will explain the creation of a simple application – the SlidePresenter – that allows […]

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

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
