Article published | Fault Handling and Prevention (II) by Ronald van Luttikhuizen & Guido Schmutz

July 11, 2013 1 Comment

Oracle Technology Network (OTN) published the article Fault Handling and Prevention – Part 2 (Fault Handling and Prevention for Services in Oracle Service Bus) by Ronald van Luttikhuizen and Guido Schmutz.

Part 1 of this article series on Fault Handling and Prevention discussed what fault handling is and why it is important. It also addressed the specific challenges in handling faults in a service-oriented landscape as compared to traditional systems. Part 1 concluded by presenting a sample scenario, an Order process implemented in a BPM and SOA environment, discussed potential pitfalls, and described generic fault prevention and recovery patterns.

Part 2 concentrates on concrete fault handling and prevention measures in the integration layer that are realized through Oracle Service Bus (OSB). The integration layer covers typical elements and integration functionality, such as Adapters for connectivity to back-end systems, Routing, Transformation, and Filtering.

Building OSB projects with Maven and removing the eclipse dependency by Mark Nelson

July 9, 2013 Leave a comment

osb In this earlier post, I talked about a way to automate the build and deployment for OSB, but I did not go so far as to get that working in Maven, though you certainly could. But, OSB PS6 has added a new tool called configjar which lets you build a sbconfig.jar file without needing to have eclipse/OEPE/OSB IDE installed on the machine where you are doing the build. You do still need OSB, but removing that IDE dependency is a big step forward.

You can find configjar sitting under your Oracle_OSB1/tools/configjar directory in your OSB PS6 installation. There is a readme file there that tells you how to use it from ANT and WLST. Here, I want to show you how to use it from Maven, and therefore Hudson, etc. too.

For this post, I went into the OSB IDE and created a simple project called osbProject1 which contains a single Proxy Service called (imaginatively) ProxyService1. It is just a plain old ‘any’ proxy service with essentially no implementation at all. But it is enough to do what we need to do. Read the full article here.

SOA and Oracle Fusion Middleware for the Busy IT Professional by Frank Munz

April 26, 2013 Leave a comment

Not everybody is starting up JDeveloper first thing in the morning in order to work with Oracle SOA Suite. Let’s face it: Instead of being an SOA expert, any given IT specialist is more likely a certified DB admin, a Java developer or somebody who was just told by his manager to take care of that Oracle Service Bus installation. In case you are one of them and looking into SOA and the related Oracle products this posting is written for you.

Technology and Oracle

The following two recipes provide firstly a no-nonsense explanation of Service Oriented Architecture (the first part is not related to Oracle at all !) and secondly an overview of Oracle’s Fusion Middleware (OFM) product stack.

The description is deliberately easy to read and I intentionally didn’t reuse any fancy marketing slides since they are often too generic and contain too many buzzwords. Read the full article here.

User Experience new content: Fusion Applications & mobile & concepts

April 20, 2013 Leave a comment

On the Fusion Applications user experience: More: New podcasts and posts on the Oracle user experience.

Here’s a round-up of recent podcasts and blog posts relating to the Oracle Applications User Experience that were published in February.

Jeremy Ashley, Vice President of Oracle Applications User Experience, talks about Oracle’s roadmap to a simple, modern user experience for Fusion Applications. Listen to learn more about the strategy behind Project FUSE. You may also access the podcast through the Usable Apps website.
Ultan O’Broin, Director of Oracle Global User Experience, talks in this podcast about why Oracle is making design patterns available for customers, partners, and the development community. These design patterns for the Oracle Fusion Applications user experience encapsulate proven best-practices and make them available for those who are extending or tailoring an Oracle application.
Richard Bingham, Oracle Applications Architect, discusses how to tailor Fusion Applications in the cloud.

On Oracle’s investment in the next-generation user experience (in this case, mobile): Intense research into mobile use helps guide design of Oracle Applications

Read about the mobile trends that the Oracle Applications User Experience team noted during a recent global expedition, which included user studies in Sweden, the United States, and Beijing.

The Oracle Applications User Experience team continues to investigate how and why enterprise workers use their mobile devices, and their findings are already influencing the next-generation user experiences that Oracle is designing.

Visit the Usable Apps website to learn more.
Also on Oracle’s investment in the next-generation user experience (a look at trends we’re following up on): A look at new concepts for the enterprise space
The Applications User Experience team is keeping its eye on new technologies that may have an impact on the enterprise space.

New concepts and technologies go through an internal research, design, and development process to assess which ones may or may not gain traction in the enterprise space.
Read more about how our findings help guide the Oracle user experience strategy on the Voice of User Experience, or VoX, blog.

From the Trenches | Patching OSB and SOA Suite to PS5 by Ronald van Luttikhuizen

April 18, 2013 Leave a comment

Recently I was involved in an Oracle Fusion Middleware upgrade from 11g PS2 to 11g PS5 with Jacco Landlust, Aiman Salama, and Jens Peters. The environment that was patched consists of the following domains:

Java domain running Java/JEE applications;
IDM domain running identity management components including OID;
SOA domain running Oracle Service Bus and Oracle SOA Suite.

The domains consist of several Managed Servers in a single-node cluster configuration. OSB and SOA Suite both run in their own Managed Server.
There are plenty of excellent blogs that discuss the infrastructure and middleware side of such an upgrade. This blogs contains some things we encountered from the application side of things. More specific, the SOA composites and OSB projects.

Rebuild custom Java classes and JAR files in the SOA extension library
You can add custom Java classes and JAR files to SOA Suite that are used by your SOA composites. The SOA extension library for adding extension classes and JARs is available in the $ORACLE_HOME/soa/modules/oracle.soa.ext_11.1.1 directory. For example, an extension can be used to add a custom fault handler. Read the full article here.

Oracle Fusion UX Design Patterns and Tools for the Cloud Crowd by Ultan O’Broin

April 13, 2013 Leave a comment

The Oracle Fusion Applications User Experience Design Patterns and Guidelines are out-of-the-box, developer productivity enablers. As ready-made, yet flexible, usability solutions, the patterns are easily applied when building Fusion applications and UI integrations in the cloud with the Oracle toolkit.

Design patterns as reusable solutions to common problems when designing are all around us. Keen to tell this story in new ways, I was inspired by an Engine Yard “Cloud Out Loud | Ruby“ podcast mention of knitting patterns on GitHub.

I assigned my partner a proof of concept project for one such knitting pattern in the cloud. The pattern was quickly applied, and reflecting pattern ideas of content and skin neutrality, I soon took delivery of “HCM” and “CRM”, two little knitted aliens. Concept proven!

Knitted aliens. Proving the design pattern concept.

Knitted aliens brought to life from a pattern in the cloud. I used this story at a SAMBA UX outreach workshop in Amsterdam earlier this month.

Our UX design patterns have been proven in usability labs, in offices, and on the street, with real users, real tasks, and real apps. We’ve done the thinking and testing so that builders of Fusion apps cloud solutions don’t have to. To get your hands on UX design patterns for use across the Fusion apps suite (not just HCM and CRM), go to the Usable Apps website “For Developers” section. Read the full article here.
