BPM 12c Advanced Error Handling and Recovery – Part 1 by Antonis Antoniou

clip_image002Introduction

The ability to handle exceptions and recover from errors is fundamental to implementing reliable and robust business processes and enterprise systems.

There might be cases, though, when an unexpected problem occurs during the runtime lifecycle of a process that will cause your process to fail. This could be the result of a connectivity loss, a failure in a database connection, a selection failure, or a failure during an invoke activity. These types of errors, (more...)

clip_image002In a SOA architecture there is often a need to create asynchronous services. As a simple example imagine a workflow approval process. In such a case the approval process can run from minutes to weeks, before the final approval returned back to the client. This is a typical example of an asynchronous service. So when a platform like Oracle SOA Suite is involved the implementation of an asynchronous service  is a quite easy task to (more...)

Monitoring MongoDB using Oracle Enterprise Manager Cloud Control

Scott Wardrop from AIDEV told me that they produced a plugin for Oracle Enterprise Manager Cloud Control 12c to monitor MongoDB. We use MongoDB in our production systems, so I decided to examine the plugin and write a blog post about it. Unfortunately version of our MongoDB databases are too old (2.4.x series) so the plugin didn’t work. Of course, it didn’t stop me. We created a simple MongoDB Cluster environment to test (more...)

How to create your own Oracle database merge patch

A little bit scary title, isn't it? Please keep in mind that definitely it is neither supported nor advised method to solve your problems and you should be really careful while doing it - hopefully not on production environment. But it may sometimes happen that you end up with the situation where creating your own merge patch for Oracle database could not be as crazy idea as it sounds :).

Deploying Apex: showing an “Under Maintenance” web page

systemdown

I’ve added this script to our toolbelt for future upgrades. We have a friendly “System is under maintenance, sorry for any convenience” web page that we want to show to users while we run upgrades, and we want it to be shown even if we’re just doing some database schema changes.

So I took the script from here and adapted it slightly, here’s our version:

declare PRAGMA AUTONOMOUS_TRANSACTION;
  v_workspace CONSTANT VARCHAR2(100) := 'MYSCHEMA';
  v_workspace_id NUMBER;

Secure Remote RESTful Administration with RAD

I've written before about the work we've been doing to provide a set of programmatic interfaces to Oracle Solaris using RAD. This allows developer and administrators to administer systems remotely over C, Java, Python and REST based interfaces. For anyone wanting to get their hands dirty, I've written a useful article: Getting Started with the Remote Administration Daemon on Oracle Solaris 11.

One of the areas I didn't tackle in this initial article was providing (more...)

My Current NetBeans Look

Quite happy with it. I set --fontsize 14 in 'netbeans.conf' file and am using the first of the two Dark Look and Feel Themes, from the plugin of the same name in the Plugin Manager. Also, Consolas 18 Bold is the font I am using. Click to enlarge the image below to get the complete impression:

Java 8 Lambda : the very basics

Functional interface

In many cases – when talking about Java 8 – lambda-functions are the first thing that comes up. I found it a concept hard to grasp, as it slightly changes the way you think about coding. In this blog, I would like to show you some very simple examples, and explain what is what in the lambda world.

In versions prior to Java 8, we had SAM interfaces : Single Abstract  (more...)

PL/SQL: The Good Parts

Somewhat inspired by Douglas Crockford's Javascript: The Good Parts presentation (and book), I have created a presentation called PL/SQL: The Good Parts.

This is not intended as an introduction to PL/SQL, but rather an overview of features you should consider if you want to maximize your enjoyment of programming in the Oracle Database. Also, this is not an exhaustive list of all features, it's simply the ones I personally use frequently.



Note that unlike (more...)

Discoverer and Windows 10

Hi everyone
Has anyone had the courage to upgrade to Windows 10 and see if Discoverer Plus still works?

How about the Discoverer server? Anyone tried that.

If you have drop me a reply

Joining Oracle

Last month I joined Oracle after nearly 20 years of working with their technology.  Some people congratulated me on my new role, others told me that going from working solo to working for a massive organisation would be disaster.  In the latter case, this was often associated with an impassioned “But why?”

To be honest, I found that a little discourteous – its an assumption that to work for a multinational is (more...)

Choose the right Singleton pattern for your project. Learn about the different ways to implement the Singleton pattern, and how to use the pattern to create a database connection whose parameters can be updated after a Java application has been compiled. 

Payene Denis Kombate explores the pros and cons of various ways to implement the Singleton pattern in his article titled Effective Ways to Implement and Use the Singleton Design Pattern. His comparison includes (more...)
