Simple problems and simple solutions

 

Most developers have struggled with wires in SOA composites. You may find yourself in a situation where a wire has been deleted. Some missing wires are restored by JDeveloper. Other missing wires have to be added manually, by simply re-connecting the involved adapters and components. Simple.

Recently, I had a real life situation of missing wires. I had a conduit where there was no longer a wire inside. Normally, there is a wire inside (more...)

Poll a Microsoft Exchange mailbox from OSB using DavMail

The Oracle Service Bus has built in features to poll an IMAP of POP3 mail account. There are loads of excellent blog posts that exactly describe how to do it. However, when the mail server happens to be a Microsoft Exchange server, things become shady. Exchange’s IMAP implementation tends to be not really that compatible, and the server log will fill up with stacktraces such as:

javax.mail.MessagingException: Connect failed;
  nested exception is:
        java. (more...)

Microservices, a different SOA approach

What are microservices?

Have you heard of Microservices yet? First time I heard the word I had strong associations with a new appliation for bacterial life in food processing. Maybe my background in biochemistry got the better of me.

Actually, the Microservices Architecture (MSA) is a new sprout on the ever-growing tree of Service-Oriented Architecture concepts. The definition sounds vaguely familiar: A particular method of designing (usually complex) enterprise software applications as suites of small, independent (more...)

Oracle Fusion Middleware Forum 2016 in Valencia

The past week my colleague Patrick Sinke and myself attended the Oracle Fusion Middleware Forum 2016 in Valencia, Spain held from March 15th to March 18th. It was a week overloaded with information, networking and deep-dive workshops. We worked hard, learned a lot and had some fun once in a while as well. The event coinciding with the annual Las Fallas festival also helped with that last part :-)

In this blog I would like to (more...)

SOA Cloud Service & Developer Cloud Service Chapters 15 & 16 by David Craft

David has continued his series on SOACS & DevCS integration and in Chapter 15 David highlights deployment from DevCS to SOACS. Note that David shows how to work with the firewall and proxy in order to successfully deploy your SOA composite to SOACS.

 

In Chapter 16 David explains securing deployment with SSL.

SOACS + DevCS – Chapter 14 – Recap and more

Chapter 14 - Recap and more is the latest entry by David Craft (Oracle Principal Member of Technical Staff) illustrating end-to-end integration between Oracle Developer Cloud Service (DevCS) and Oracle SOA CS.

Oracle SOA/BPM: Payload Validation per Composite

In this article I will explain how you can enable payload validation in the Oracle SOA/BPM Suite per composite, both design and deployment time. This works for 11g as well as 12c

When developing BPM processes or SOA services it is advisable enable payload validation on the development server. The reason being that this will force you to work with more representable test data, and in some occasions help you preventing coding errors (like (more...)

Oracle SOA/BPM 12c: Propagation of Flow Instance Title and Instance Abortion

Recently I wrote this posting regarding an improvement for setting the title of a flow instance in Oracle BPEL, and BPMN 12c. In this posting I will discuss two related improvements that comes with SOA/BPM Suite 12c, being that the flow instance abortion is automatically propagated from one instance to the other, as well as the flow instance title. Or more precisely, for every child instance the initiating instance is shown together with its name.

Groovy Time! How to use XML dateTime and duration in BPM 12c

In this article I show some examples of handling XML dateTime and durations in Groovy in the context of a Oracle BPM 12c application.

Working with dates and durations in Java has always been painful. Mainly because date and time is a complex thing, with different formats and time zones and all, but I sometimes wonder if it has not been made overly complex. Anyway. Working with XML dates is even more complex because the (more...)

Oracle BPEL & BPM 12c Set Flow Instance Title

In this article I describe how to set the instance title for a composite in Oracle BPEL or BPM 12c.

Sometimes little, annoying things that are fixed with a new release can give great joy. With 11g you could set the composite instance title using the (advanced) XPath function setCompositeInstanceTitle(). This helps to find or identify instances in Enterprise Manager. However, for high volume composites you may want to configure in-memory-optimization as well by adding (more...)

Integration Is Hard

If you know me at all, you know I love services-based integration.  The whole idea of interfacing, moving and exchanging data, guided by industry standards...I'm an enthusiastic supporter.  The appeal of this idea made me an ardent supporter of Oracle's Fusion Applications.  And I still believe it's an important part of the potential for today's SaaS offerings.

So I'll share a secret with you...I really hate services-based integration.  It's hard.  Packaged integrations rarely (more...)

Oracle BPM / SOA Instance Migration Script Issues

In this blog posting I explain some changes you need to apply to get instance migration to work for the Oracle BPM 11g Suite.

While figuring out a couple things about instance migrations I have been doing a few Bundle Patch installations lately. Up to 11.1.1.7.0 + BP4 I had issues with migration even after applying patch 18025048. I just applied BP7 and installed the latest 11.1.1.7.0 (more...)

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...)
