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

tweaking the entropy pool for a better SOA performance

At my current assignment, I’ve gone to great lengths to improve the Oracle SOA Enterprise Manager Console performance. One of the actions I took, was purging about 700 gigabytes of data from the dehydration store. Although that solved lots of other problems, the EM still wasn’t very responsive. Loading composite details could take op to 20 minutes, it they ever loaded at all. Apparently, the database was ok, because there was no load at all (more...)

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...)

BPM workspace: Scripted security

When implementing BPM processes, for each deployed BPM process an application role is created in the policy store. To enable users to work with the processes, groups are assigned to these application roles. Users are ofcourse assigned to their respective groups. Management of the BPM process application roles is available in Enterpsie Manager Fusion Middleware Control or the BPM workspace.

Let’s first use Fusion Middleware Control. We need to go to the security section.

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

Fusion Applications: Some Suggested Reading

I just finished a really nifty book:  Oracle Fusion Applications Development and Extensibility Handbook.  Required reading for anyone working with Fusion Applications.

The organization of the book is one of the reasons I highly recommend it.  The first four chapters lay out a foundation of knowledge need by anyone working with Fusion Applications in a functional or technical role.  The remaining 11 chapters provide deep detail (including instructions with pictures) on personalizing, (more...)

Unable to change WS Policy Store to “App Server Connection” in JDeveloper

Today when trying different settings with Basic Authentication and SOA Suite, I wanted to from the embedded OWSM Policy Repository of JDeveloper to the one stored on the application server. In JDeveloper you can do that through preferences (Tools | Preferences). See this blog for more details.

Click on the App Server Connection option and choose an existing connection through the Connections drop-down or add a new one by clicking New.

Poster published: Adaptive Case Management (ACM) in Practice

Knowledge-driven processes are typically unpredictable in their execution. Experts working on them decide what’s the next best action to take. This is in contrast to traditional BPM, in which all possible paths of a process are predetermined and modeled into the process. Adaptive Case management is a way to control (more...)

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...)

Why in Business driven information its the consumers view that matters

When doing the Business Data Lake pieces it took me back to a view that I had around SOA in that you should take the consumers view when designing a service.  This I think is more critical when looking at analytics and reporting where it really is all about the consumption. What (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:

How Business SOA thinking impacts data

Over the years I've written quite a bit about how SOA, when viewed as a tool for Business Architecture, can change some of the cherished beliefs in IT.  One of these was about how the Single Canonical Form was not for SOA and others have talked about how MDM and (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...)
