Bryxx has launched!

On Tuesday, May 7 the Bryxx launch event took place. In the beautiful setting of the Flandria boat, and in the presence of a large number of customers, we revealed the services of this new venture. As a joint venture between the iAdvise and Contribute infrastructure teams, Bryxx will specifically focus on the middleware field.

In bringing together both expert middleware teams, we will focus on

• Opening up your business critical web applications to your intranet or to the internet
• Making sure that these applications, deployed on your middleware stack, are secure on all layers of the underlying architecture. Security from-data-to-browser
• Streamlining and automating your process of development towards production
• Providing you with the opportunities to outsource the maintenance of your private middleware cloud or to outsource your entire private middleware cloud

From a technical point of view Bryxx will dedicate its expertise to 4 domains:

• Oracle Cloud Application Foundation (with web logic as the main driver)
• Oracle Identity & Access management
• Oracle Database Security
• DevOps

With respect to these 4 areas of expertise, Bryxx provides strong consultancy profiles on all levels (pre-sales, infrastructure architects, senior implementation engineers, etc) to design, install, configure, maintain and monitor your middleware platform as well as to streamline the process of application development towards your preferred middleware solution.

When you add our managed services and hosted solutions offering on each of these domains to this package, with strong partnerships in the backend, we believe Bryxx has a strong and complete offering for all your middleware challenges !Our team of 14 dedicated and experienced middleware engineers is ready for you.

Why should you attend Oracle OpenXperience on 25 October in Brussels?

Because it’s there that you’ll find out how your organisation can benefit from Oracle’s new technologies!

Are mobility and the cloud opportunities for your organization or threats to its security?

Can applications, hardware and software really work together?

Is Oracle 12c a sensible investment?

Is drowning in (big) data unavoidable?

How can business intelligence become an integral part of IT structure?

If at least one of these questions rings a bell, you should attend Oracle OpenXperience. It’s where 10 of Oracle’s most valued partners will present their (local) views on today’s IT challenges and Oracle’s solutions for tackling them. It’s where you’ll discover the practical approach of our partners, in 12 sessions divided into 3 distinct tracks.

For the bigger picture, don’t miss the keynote sessions. Mario Derba, Regional Vice President Systems Sales, South Europe, will share his insight on Oracle’s worldwide strategy. After lunch, famous Belgian innovator, consultant and strategic influencer Jo Caudron will talk about current trends and how they affect IT and your business.

All things Oracle

There’s a new Oracle source available:  All Things Oracle.

The aim of All Things Oracle is to provide a gateway to the wealth of information and material available for Oracle developers and DBAs.
The site brings articles and other resources of Oracle experts.
Just to name a few:

• Alex Nuijten -Database Development – Oracle Ace Director
• Cary Millsap – Software Development – Oracle Ace Director
• Dimitri Gielis – Oracle Application Express – Oracle Ace Director
• Martin Giffy D’Souza – Oracle Application Express – Oracle Ace
• Roel Hartman -  Oracle Application Express – Oracle Ace Director
• Scott Spendolini – Oracle Application Express – Oracle Ace Director

All very experienced experts that will bring interesting articles!

I will also contribute to this site.
My specialities are SQL, PL/SQL, Forms and Forms Modernization, so expect articles on these topics in the near future on All Things Oracle.

My quiz on the PL/SQL Challenge

On friday my quiz was on the PL/SQL Challenge.

Topic: “Guidelines for Designing Triggers: Avoid Non-Transactional Logic in DML Triggers”

Yes, about “statement restart”
My idea about the quiz was “making developers aware of the Oracle behaviour”.
And I hope a lot of PL/SQL developers learned from it.

It wasn’t easy to come up with the question, the way of asking, the correct words, the answers…
But after a lot of mailing between Steven and the reviewers we finally had a quiz.

A lot people had it wrong, but I hope they don’t mind and are now aware of statement restart.

For more information and discussion about the quiz: PL/SQL Challenge blog

Statement restart

Today I explained the “statement restart” problem to a colleague.
Every database developer has to know about this one…

Short: Any statement can be restarted!
This means that when you do one update statement, oracle CAN restart the statement.
Every code in a trigger can be executed multiple times, so watch out with package variables and autonomous transactions in triggers.

Some code to test it:

CREATE TABLE test_trigger(val NUMBER)
/

CREATE OR REPLACE PACKAGE global_var
IS
g_val NUMBER;
END global_var;
/

CREATE OR REPLACE TRIGGER test_trig
BEFORE UPDATE
ON TEST_TRIGGER
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
global_var.g_val := global_var.g_val + 1;
END ;
/

BEGIN
global_var.g_val := 0;
END;
/

INSERT
INTO test_trigger
( val
)
VALUES
( 0
)
/

DECLARE
l_val NUMBER;
BEGIN
SELECT val
INTO l_val
FROM test_trigger;

dbms_output.put_line(‘value in package global variable:’||global_var.g_val);
dbms_output.put_line(‘value in table:’||l_val);
END;
/

BEGIN
FOR i IN 1..100000
LOOP
UPDATE test_trigger
SET val = val +1;
END LOOP;
END;
/

DECLARE
l_val NUMBER;
BEGIN
SELECT val
INTO l_val
FROM test_trigger;

dbms_output.put_line(‘value in package global variable:’||global_var.g_val);
dbms_output.put_line(‘value in table:’||l_val);
END;
/

What’s the value of your global variable?

Or like Tom Kyte says: “Triggers or evil!”
