The Secret Feature of Bucketsets in Oracle Business Rules

In Oracle Business Rules one can use so-called "Bucketsets". I never liked the term as it is not in the dictionary (did you mean bucketseat?), and never understood what is wrong with "list of values" (LoV) as that is what it is.

See for example the following bucketset that defines a list of values to be used for some status field:


Anyway, bucketsets are typically used in decision tables to define the set (more...)

Oracle APEX_WEB_SERVICE REST API call

In this post I will try to show you how I used the Oracle Apex and the APEX_WEB_SERVICE  PL/SQL package to quickly send a request to a public Internet API and how I handled the response. The code below was written during a 'Hackday' and hasn't been extensively tested.

My use case is integrating Oracle Apex with the public Mendeley REST API for Mendeley Catalog Search.

The idea was to build an (more...)

Making DevOps Business Driven – a service view

I've been doing a bit recently around DevOps and what I've been seeing is that companies that having been scaling DevOps tend to run into a problem: exactly what is a good boundary for a DevOps team? Now I've talked before about how Microservices are just SOA with a new logo, well there is an interesting piece about DevOps as well, its not actually a brand new thing.  Its an evolution and

OBPM versus BPEL, That’s the Question

Recently I was pointed to the so-called Oracle Learning Streams http://education.oracle.com/streams which provide short presentations on all kind of topics.

While ironing my clothes on a Sunday afternoon, I watched one with the title "Leveraging OBPM vs BPEL" by David Mills. An excellent story where he explains in less than 13 minutes the high-level difference using a practical example.

One reason why I like about this stream is that it is in line (more...)

Create with WLST a SOA Suite, Service Bus 12.1.3 Domain

When you want to create a 12.1.3 SOA Suite, Service Bus Domain, you have to use the WebLogic config.sh utility.  The 12.1.3 config utility is a big improvement when you compare this to WebLogic 11g. With this I can create some complex cluster configuration without any after configuration. But if you want to automate the domain creation and use it in your own (provisioning) tool/script then you

Oracle SOA Suite 12c tips – Tuning the SOA infrastructure thread pool

One of the new capabilities of Oracle SOA Suite 12c is the ability to control the SOA infrastructure thread pools, except the resource pools for EDN and the adapters, with Oracle WebLogic Server work managers. Each partition will has its own work managers defined. This allows you to separate services in partitions and, to some extent, tune them separately based on for example specific SLA requirements.

Well, this blog posting is not about explaining the (more...)

Maven support for 12.1.3 Service Bus & SOA Suite artifacts

With the 12.1.3 release of Oracle Service Bus and Oracle SOA Suite we finally can build all our soa projects with Maven. And this time we can do it natively without calling a utility like configjar or ANT from Maven . We start by setting all the required variables like JAVA_HOME,M2_HOME and PATH export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre export M2_HOME=

Lipstick on the iceberg – why the local view matters for IT evolution

There is a massive amount of IT hype that is focused on what people see, its about the agile delivery of interfaces, about reporting, visualisation and interactional models.  If you could weight hype then it is quite clear that 95% of all IT is about this area.  Its why we need development teams working hand-in-hand with the business, its why animations and visualisation are massively important.

Microservices is SOD all within SOA

Microservices is a Service Oriented Delivery approach, all within a Service Oriented Architecture context. (Long Title ;) Ok so a few more updates since the last time I wrote about Microservices and I think its worth just updating as it really is heavily underlining why Microservices is a Service Oriented Delivery approach that absolutely can fit within a Service Oriented Architecture.  Lets be

Microservices is SOA, for those who know what SOA is.

Ok so its started a bit of debate on Twitter and now there have been emails, but in the spirit of openness I thought I'd better blog.  Now its good that Martin has now added a side bar on SOA to his article on Microservices but that really makes it worse in many ways.  I'll get to that at the end but first off lets explain why Microservices is just another SOA implementation pattern.  Its SOD

Microservices – Money for old rope or re-badging SOA for the cool kids

Hat tip to John Evedemon for the heads up on this one.  Martin Fowler is peddling a new approach, 'Microservices' which... wait for it is a way of developing applications as a suite of services.  Each one of which has its own process thread and 'communicates via lightweight mechanisms' such as.... over HTTP. But wait there is more, you'll be stunned to know that these services can be built

Altova XMLSpy, testing custom functions in xsl transformations

In our middleware solutions (Oracle SOA Suite) we use a lot of xsl transformations.
Part of these transformations use database backend systems to do lookups for transforming internal values to external values (which can then be communicated to the customers).

In the Oracle SOA Suite you can create custom xsl function and store the jar in the domain/lib folder and then you will be able to use it in the xsl transformations.

We use Altova (more...)

REST, SSE or WebSockets on WebLogic 10.3.6

WebLogic 10.3.6 comes with Jersey1.9 and has no support for Server Side Events or WebSockets. But for one of our projects we are making a HTML5 / AngularJS application, which need to invoke some RESTful services and we also want to use of SSE or WebSockets. Off course we can use WebLogic 12.1.2 but we already have an OSB / SOA Suite WebLogic 10.3.6 environment. So when you want to pimp your

Webservice interaction patterns – part 2 – Synchronous Webservice call timeouts

Goal: For reasons of performance and more importantly, good user experience, he client application (ADF) should be able to timeout gracefully instead of hanging indefinitely (and/or potentially causing STUCK threads on the ADF server) when invoking an external 'synchronous' web service.

At runtime
When I run the application,
If I (more...)

Webservice interaction patterns – part 1 – very basic DML

There are a number of ways you 'call' web services from an ADF application. The best method to choose would depend on the individual scenario.

This particular example is the most suitable option where:
- Our application is allowed to read from the database using its own business services - (more...)

Browsing the Meta Data Services Repository of the Oracle SOA/BPM Suite 11g

In this article I explain a handy way to browse the MDS on the SOA/BPM server from JDeveloper, as well as an (as far as I know) undocumented feature to look up artifacts using a browser.

The Meta Data Services (or MDS for short) of Oracle's SOA/BPM Suite is used (more...)

How to Make File-Based MDS in JDeveloper Work for both Windows and Linux

In this article I explain how you  can modify the JDeveloper adf-config.xml file to make it work for both Windows, as well as Linux.

If in a JDeveloper application you point to artifacts in a file based MDS residing in a Windows folder for example "d:\projects\MDS", then JDeveloper will (more...)

Review: Oracle SOA Suite 11g Developer’s Cookbook

As the title says, this is a “Cookbook” containing specific recipes for handling specific tasks. Most of the tasks are development tasks faces by a SOA developer with a few that are more relevant to a SOA administrator.

The 67 recipes cover many components and technologies used in the very (more...)

Using Bean Validaton in SOA – JEE 6 based sample application

This blog post is just a short notice to point to a JEE6 based sample, which was prepared for a JavaOne session "CON5020 - Using JSR 303, Bean Validation, with the Common Data Model in SOA". The sample, available at github, contains a list of NetBeans  (maven)  projects showing the (more...)

ADF & Event driven Integration with a BPMN process


The usecase for my sample application is:
A standalone application exists to create/update 'Departments'. Originally, it was not intended to be part of an automated process (BPEL or BPMN) but now business decided that their process for the creation of a department is actually more than just data entry in the standalone application. It also now involves an approval. 


Background:
1. Every interaction with a software application in a business environment is part (more...)
