My first experiences with ThreadLogic by Marcel van de Glind

clip_image002A while ago I came into touch with ThreadLogic. Most of the people whom I was talking about it, did not know the tool. This unfamiliarity with ThreadLogic made me decide to write this blog. I think that every WebLogic Administrator should know ThreadLogic and that it is also a very interesting tool for Fusion Middleware Developers.

But let me start at the beginning. A while ago Michael Sahadat, a SOA/Integration Architect at Oracle, came over to help me solve a performance issue. He was using ThreadLogic and explained me how it helped us at the end to detect the performance bottleneck. But that I will explain later on. First I will tell about ThreadLogic.

What is ThreadLogic?

ThreadLogic is a Thread Dump Analysis tool. Thread Dump Analysis is a key tool for performance tuning and troubleshooting of Java based applications.

Most TDA tools dont mention the type of activity within a thread, should it be treated as normal or deserving a closer look? Can a pattern or anti-pattern be applied against them? Any possible optimizations? Are there any hot spots? Any classification of threads based on their execution cycles? ThreadLogic is created by the Oracle Fusion Middleware Architect Team (A-Team) to address these deficiencies.

Once a thread dump is parsed and threads details are populated, each of the thread is then analyzed against matching advisories and tagged appropriately. The threads are also associated with specific Thread Groups based on functionality or thread group name.

The current version of ThreadLogic is V2.0.217. Since version 2.0.215 it contains support for SOA 12c.

How did ThreadLogic help us?

After creating two threaddumps in WebLogic we loaded them in ThreadLogic. ThreadLogic immediately gave a Warning. Bottleneck among threads.

Opening the dump tree and selecting the Advisory Map show a Map with information about the health of the system under investigation. Each of the advisory has a health level indicating severity of the issue found, pattern, name, keyword and related advice. As you can see in the picture below, our system has a number of FATAL and WARNING issues. Read the complete article here.

Creating and scaling Dynamic Clusters using wlst by Jaap Poot

clip_image002Introduced in Weblogic 12.1.2, dynamic clusters is a great feature to scale your private cloud.
Dynamic clusters provides you easy scaling of Weblogic clusters by adding and removing managed server instances on demand. They contain one or more dynamic servers. These dynamic servers are based on a single servertemplate that guarantees that every member of the cluster is exactly the same.

Creating Dynamic Clusters

Let's take a look at some of the possibilities as we create a dynamic cluster.

I have created a virtualbox environment.
This environment consists of four VM's with the following specs.

  • 2 vCPU's
  • 4 Gb memory
  • 50 Gb disk
  • Oracle Linux 6.6
  • Java 1.7.0_75
  • Weblogic 12.1.3.0.2

I created a simple domain called demo_domain with only an AdminServer and four machines.
After unpacking the domain to the four servers, the nodemanagers where started and are reachable by the AdminServer.

Now let go through the process of creating a dynamic cluster.
Open the Weblogic Console and navigate to Environment -> Clusters
Lock and Edit the domain in the Change Center. Read the complete article here.

Docker – Take Two – Starting From Windows with Linux VM as Docker Host by Lucas Jellema

clip_image002My first attempt with Docker was from my Windows host machine using boot2docker, as described in this article: https://technology.amis.nl/2015/03/15/my-first-steps-with-docker-starting-from-windows-as-the-host/. Boot2docker is a great tool for being able to work with Docker on a Windows machine. However, I ran into limitations – such as not being able to create containers with the GUI applications running in them. Besides, Linux seems to be – for now at least – the more natural environment for Docker. So decided to create a Linux VM – actually a Virtual Box VM – that would serve as my Docker host.

In this article I will walk through the steps I went through in order to get this Linux VM running on my Windows host and subsequently turn that VM into the Docker Server in which one or more containers will be running – eventually to serve as demo and training environments, for example with Oracle Databases and Middleware. After all, Mark Nelson showed the way in this wonderful article: https://redstack.wordpress.com/2014/11/14/gettingn-to-know-docker-a-better-way-to-do-virtualization/.

I decided to closely follow Mark’s lead in his choice of Linux VM: Ubunty 14.04.1, to be created using Vagrant (about which I have blogged before – for example https://technology.amis.nl/2014/06/26/provisioning-an-oracle-11g-database-virtualbox-vm-with-vagrant-and-puppet-for-dummies/ ).

Stage One – Create Ubuntu VM using Vagrant

I have both Vagrant and Virtual Box set up on my laptop. From that starting point, I open a command line window and create directory into which to create the Vagrant configuration for the VM. Read the complete article here.

WebLogic Server Now Running on Docker Containers by Monica Riccelli

clip_image002We are very excited to announce that Oracle WebLogic Server is now certified to run on Docker containers. As part of the certification, we are releasing Dockerfiles and supporting scripts on GitHub to build images for Oracle WebLogic Server.  These images are built as an extension of existing Oracle Linux images Oracle Linux Images. You can use these Oracle WebLogic Server Docker images or create your own. To help you with this, we have posted Dockerfiles and scripts on GitHub as examples for you to get started.

Docker is a platform that enables users to build, package, ship and run distributed applications. Docker users package up their applications, and any dependent libraries or files, into a Docker image. Docker images are portable artifacts that can be distributed across Linux environments. Images that have been distributed can be used to instantiate containers where applications can run in isolation from other applications running in other containers on the same host operating system.

The table below describes the certification provided for various WebLogic Server versions. You can use these combinations of Oracle WebLogic Server, JDK, Linux and Docker versions when building your Docker images. Read the complete article here.

Smart Code Completion

The NetBeans IDE's Java Editor helps you quickly complete and generate code through the "smart" code completion feature. In a general sense, code completion is very useful when you want to fill in the missing code, look at the options available in the context of your application, and generate blocks of code when needed. See below for examples of how to use code completion. Get the reference guide here.

IFrame in ADF Application – Menu and Show Page in IFrame by Rohan Walia

clip_image002

ADF Applications uses power of reusable task flows to be embed as regions in the page, which can be refreshed based on the use cases.
But there are some requirements by the clients which still emphasize on using Iframe to display different applications inside one application.
Suppose there is a requirement where there are 3 applications A,B and Consuming Application. All three applications A,B and Consuming needs to be deployed as separate EAR(Applications) and Consuming App needs to display the A and B Applications pages inside its main page.
Portal architecture can also fit for this requirement but if there is only ADF you need to implement this, the only choice to do is using Iframe.
In this post I will explain you how we can create a menu and show another application in IFrame in ADF Application.
We will use af:inlineFrame component to achieve this. Below is the use case.

The above diagram is for consuming application and Links in the menu (TestPage1 and TestPage2) refers to another application and the pages on click will open in right hand side inside Iframe.
Lets get started.
Created an ADF Application which has two pages. This will be deployed before the Iframe Application. Read the complete article here.
