A Simple Example of an Index Organised Table Without Overflow

For a long time I have had a note on my task list to learn about index organized tables. I never got round to doing it because I thought I would never see one. However, I came across several in a 3rd party application recently. An index organized table is a kind of index and table combined. You can see how they work in the example below, which I tested in an Oracle 11. (more...)

Scripts “All Things Oracle” article on Oracle Live SQL

I've put the scripts of my All Things Oracle article "About functions, records and result cache" on Oracle Live SQL.  This makes it easier to test the code used in the article.  

I used the employees table from the HR demo schema for my examples which is already available in Live SQL, so you don't have to create anything but the functions used in the scripts.

I've created 4 scripts:

This blog post is a continuation to an earlier post about my musings on Oracle EBS support for virtual host names.

Actually, most parts of Oracle E-Business Suite work with virtual host names with out any problem. The only component that doesn’t work when using virtual host names are the Concurrent Managers. Concurrent Managers expect that the node name defined in the Concurrent Manager definition screen matches the host name FNDLIBR executable reads at (more...)

Eye Eye

As somebody who visits customers regularly I know the benefit of eye-to-eye communicaton. A great idea has been suggested at work when this is not possible, for instance when on a conference call or working remotely.

Try and use your internal directory to bring up the picture of the colleague you are talking to in order to live in the moment. Linkedin may also be a worthwhile option.

Using Dynalink API with invokedynamic – a Java assembler example

Dynalink API JEP-276

Dynalink API ( provides a facility for linking high-level operations on objects such as "read a property", "write a property", "invoke a callable object", etc., expressed as names in INVOKEDYNAMIC call sites. Dynalink also provides a default linker for the usual semantics of these operations on plain Java objects (Java POJO "beans" linker), as well as a facility for installing your own language-specific linkers.

Dynalink has been (more...)

A Different Type of Keynote & Jonathan Lewis Panel Session at UKOUG Tech15

Technical people tend not to enjoy Keynotes at conferences. We are allergic to content-light “there has never been a better time to invest in our products” fluffy, frou-frou, big picture talks. We want how-it-works meat on the bones of what is served up to us.

OK, it's a very poor photo but the best I have of Dom presenting. Sorry Dom.

DOAG annual conference 2015 – great as always!

Another annual DOAG conference has passed, and I can only say the very best about it: Perfectly organized, large and modern location, impressive list of well known speakers and over 2100 attendees – wow!


My presentation Best of RMAN was scheduled at the first slot on the first day, so I was a bit concerned whether many people would attend that early. It turned out that the room got so full that I was asked (more...)

CERN IT-DB group develops a new WebLogic Command Line Interface tool for CERN Java Middleware Services

Oracle WebLogic 12c introduced a new REST API for managing and monitoring several aspects of a domain in a lightweight and fast manner. These RESTful interfaces represent the current industry standard followed by the noteworthy and widely used Oracle WebLogic application server. Feature introduced some time ago, but improved in the current Server version, allows administrators to access the most important WebLogic Server runtime values using a simple URL. Having every reason to believe that the potential of WebLogic REST services and its maturity level is apparent, CERN decided to implement a CLI system (more...)

ADF 12.x: Changing the List Of Values "No rows to display" text

In this post I describe how I implemented an interesting Use Case where the customer wanted to have an alternate message in the LOV when there is no data found. We all know how this can be changed in an af:table component by simply changing the emptyText property. In a List of Values, this works 'slightly' different. Lets start with the basics By default you will see the following List Of

Processing large XML files in the SOA Suite

Read large XML files in chunks


At my current project, XML files are uploaded by the end-user to be processed in the Oracle SOA Suite. The XML files contain information about employers and their employees. Because an employer can have hundreds and even thousands of employees, these XML files can be quite large.
Processing such large XML files consumes a lot of memory and can be a bottleneck especially when multiple end users are (more...)
