Oracle Tuxedo… A renewed acquaintance
Oct 27th
Years ago, when I worked as an Application Support Analyst for a big triple-A Bank, I got acquainted with the BEA product stack.
One of those products was BEA Tuxedo, at that time at the release of 6. I worked at a settlements project, and Tuxedo was used for as distributed transaction processing, to process settlements an clearing messageg from the bank to an international Clearing an Settlements Project, called CLS. It used the SWIFT network to connect; CLS was an international and timezone independent settlements and clearance platform to overcome timezone and bankrupt issues, and prevent a domino effect when an important bank in the chain becomes bankrupt.
Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages.
Tuxedo was designed for high availability and to provide scalable applications to support a lot transactions per second on commonly available distributed systems. It was developed and designed by AT&T if that required online transaction processing (OLTP) capabilities.
Tuxedo is a message routing and queuing system. Requests are sent to named services and Tuxedo uses memory based inter-process communication facilities to queue the requests to servers. The requester is unaware of where the server that actually processes the request is located or how it is implemented. In fact, Tuxedo was already implementing the SOA, in the early days before even the concept of SOA was familiair to any one.
Oracle acquired it in 2008, along with all other products from the BEA stack. I was really curious how Oracle would position this product, but during Oracle OpenWorld 2011 it became clear to me.
Oracle Tuxedo 12c will be part of the new Exabus stack, a component embedded in the Exalogic solution Oracle launched some earlier.
In this picture, you can see the position of the Exabus stack and in particular Tuxedo:
Quickly creating, deploying and testing a WebService interface for ADF Business Components
Dec 29th
As you probably already know, ADF Business Components can very easily be exposed through a WebService interface. An Application Module can be configured with a Service Interface, ordinary ViewObjects and custom methods can be exposed in that interface and deployment is relatively straightforward. In minutes, a WebService can be published that exposes operations based on regular ADF BC functionality. This may well give us the fastest way to provide data services on top of a relational database. Several excellent articles have been published on the ADF BC service interface, for example by Steve Muench and Andrejus Baranovskis.
The blog-article you are reading is created as the result of my research and investigations around an article I hope to publish in Oracle Magazine later in 2011. It is adamant for this article that readers can get the example to work with the smallest number of instructions possible – both to make their life easy and to save on words. The article describes a BPM process that interacts with the HR schema of an Oracle RDBMS as one of its activities. The focus in the article will be on BPM, not on exposing data services for the HR schema. The WebService should therefore be available in a starter application, and be deployable without any fuzz or configuration overhead.
This blog-article demonstrates how to rapidly create the HRService – an ADF BC driven WebService on top of the EmployeesView ViewObject that exposes the EMPLOYEES table in the HR schema through the Employee EntityObject. However, its true purpose is to show how to create the deployment profile and deploy and test this service, either on the integrated WLS or on a standalone WebLogic Server, in the easiest way possible. Note that this easiest way is not the suggested way of working for real production environments.
This article assumes – in case you want to follow along for yourself – that you have JDeveloper 11g PS2, Oracle RDBMS 10gR2 or later with the HR sample schema and the SOA Suite 11g Run Time environment.
Configure JDeveloper 11g to work with Spring 2.5 and AOP
Dec 12th
In a recent article I described the interaction between JavaServer Faces (1.2) and Spring Framework (2.5.x): http://technology.amis.nl/blog/6655/spring-a-surprise-on-a-jsf-developer-how-spring-beans-can-become-jsf-managed-beans. I created a JDeveloper 11g web application that I ran on the integrated WebLogic Server 11g (10..3.2). In this article I will explain the configuration steps I had to go through for making JDeveloper and WebLogic run my simple JSF/Spring application.
1. Create a new generic JDeveloper application; set the project name and add the JSF library
2. Install the JDeveloper Spring extension through the Check for Updates facility under Help in the main menu
