Mediator throwing incomplete BusinessFaultException

A while ago I ran into the issue that business fault information was not returned to the calling system by the Mediator component in the SOA composite. Instead, only a message that a business fault occurred was responded to the calling system. The response would look something like the below example:

<env:Envelope xmlns:env="">
				<env:Text xml:lang="en-US">oracle.fabric.common.BusinessFaultException</env:Text>


Exadata Storage Server Patching in 18.1.1 and Above

One of the cool new features that was introduced with was a subtle change in the Exadata storage server patching process.  While not required, this new functionality removes the need to use patchmgr to drive Exadata storage server patches.  In Juan Loaiza’s Open World session on new Exadata features, this slide jumped out to me:

While this slide may look like marketing fluff, this new feature turns out (more...)

Using multiple Authentication Schemes for your APEX application

Recently someone asked me how he could implement multiple authentication schemes for his APEX application. He would like to use (some kind of) Single Sign-on authentication and - as an alternative - an Application Express Authentication. The problem is ... you can only define one Authentication Scheme being "Current" for an application! So how can we solve this issue?

First, we need te be aware that multiple applications can share their authentication by using the same (more...)

I’m back, again, late 2017

Nothing much to say other then I'm back again, and hope to do some more blog posting soon. My excuse for the lack of posts is that I've been busy helping a client with a large data migration project. That is now over, with all the data successfully extracted for loading into their new system, so I've got more time available to properly write up some technical Oracle or performance posts.

We -as a country- are no longer to be trusted?

Who Do You Trust? As legislation changed, Mozilla filed a bug with potential serious consequences. Check out bug 1408647. Removing the root certificate as trusted authority makes it look asif any certificate, issued by any of the Dutch PKI organizations, is potential unsafe. Which is correct, to a point, as the law allows the use of false keys by the Ducth autorities. Creepy. That makes the

The APPROX_MEDIAN Function – A Test Case

The aim of this post is not to explain how the APPROX_MEDIAN function works (you find basic information in the documentation) but to show you the results of a test case I run to assess how well it works.

Here’s what I did…

I started in the Oracle Database Public Cloud an instance of version 12.2.

Then I created a table with several numerical columns (the name of each column shows how many (more...)

Jarvis Pizzeria: Handle SOAP Faults within PCS

| Oct 29, 2017
As we are very optimistic developer we started out with modeling and testing the happy flow of our Jarvis pizzeria. But as experience learns it is the big bad world that obliges us to deal with both expected and unexpected failures. This blog post we will look into the handling of SOAP faults that PCS has to offer out-of-the-box.

As a starting point we have created a basic process with one service call:
This SOAP (more...)

Tracing a session SQL in "Azure SQL"

With our 'cloud first' strategy we are trying to make use of Azure SQL for all of our databases as much as possible. This (as we have discovered) does come with a few things you need to be aware of as this is not 'normal' SQL Server - there are various things that are not there and quirks about the way some of the things work.

In a case this week we were having trouble (more...)

PGConf.EU, Postgres Rocks!!

On a rainy Tuesday morning we set off on a Polish Airlines flight to Warsaw.
Our target: PGConf.EU with some of the biggest crew EnterpriseDB ever sent off.
Our goal: spread the love of EDB within the PostgreSQL community, where EDB is such an intrinsic part of.

The evening before the conference promises to be an interesting one. We have rented off the Hard rock Cafe in Downtown Warsaw for the kickoff of our (more...)

Testing network connectivity from Cloud Foundry Application Intances

This app below simply tests whether a host:port is accessible from a CF app instance. For example can my application instance access my Oracle Database Instance running outside of PCF given application instances need network access to the database database for example.

You can use bosh2 ssh to get to the Diego Cells if you have access to the environment or even "cf ssh" if that has been enabled.

2017 hroug – Croatia

I came to #hroug2008 and although I really enjoyed it there were not any english speaking presenters and I found that intimidating. However now the SiOUG and hroug events run back to back, it is very different.

The event is still held in Rovinj but now on an island at the Hotel Istra. To even get there you have to go by boat.

It is a beautiful setting complete with its own castle which is (more...)

prelink makes instance unusable

I spent a recent night hunting an issue which was non trivial to detect.
On a 4 node cluster 2 nodes got Linux patches and were rebooted. This was done after 10pm for minimal business impact. (The application is written by Oracle - so it's not fully TAF aware).
The DBs started fine, all services were available.
At 3:50 in the morning I got a call some processes show strange errors.
As I connected to (more...)

Free trial access of the Oracle Licensing training course


This is a message from my friend and Oracle licensing expert Sibaji Dey Choudhury.

Oracle Licensing has been a global challenge for a number of years now, and a lack of deep understanding on Oracle Licensing has derived $$ Millions during audits from unaware Oracle customers. To help tackle this issue 'Licensing Circle' was built to train and certify Oracle professionals on a comprehensive, portal-based knowledge on Oracle License Management.

CTAS-Statement-Texte in 12.2 Trace-Files nicht mehr gekürzt

Der Titel ist beinahe länger als der folgende Text, aber was tut man nicht alles, um den eigenen Blog nicht völlig einschlafen zu lassen: Martin Bach weist in seinem Blog darauf hin, dass die Texte in der SQL-Trace-Ausgabe für "create table as select" (aka CTAS) in 12.2 nicht mehr auf 20 Zeichen gekürzt werden, was in älteren Releases der Fall war und die Analyse solcher Operationen über Trace erschweren konnte. Darüber war ich in (more...)

Manually rotate WebLogic Server Logfiles

From time to time you have the requirement to rotate the WebLogic Server Logfiles manually on the fly without stopping the WebLogic Managed Servers or AdminServer, for example while you perform some load tests in order to have fresh WebLogic Server Logfiles.

Here is a small Python Script, which rotates the WebLogic Server Logfiles for a list of given Managed Servers and AdminServer.

You will need:

Integration Cloud Service, SOA Cloud Service or Integration Cloud, are you confused?

Jarvis Pizzeria: Test against the Development or Production environment

| Oct 23, 2017
Within PCS there are actually two different environments, a development environment and the production environment. Once you have deployed your application it is available in the production environment as a certain version of the application. However, you might want to test your application before you deploy a new version. You can also test your environment against the so called ‘development environment’.

The blue button bar has a Test as well as an Deploy button on (more...)
