Emphasis on emerging technology shapes user experience strategy

Editor’s note: For posterity’s sake, I’m reposting some content that we created during our time at Oracle. These statements and views are those of the author and do not reflect those of Oracle’s current user experience organization.

Emphasis on emerging technology shapes user experience strategy

The AppsLab, the OAUX emerging technologies team, has a passion for investigating how emerging interactions and technologies can benefit Oracle users.

While this team has existed for many years, Oracle (more...)

5 main building blocks of the new Visual Builder Cloud Service

In may 2018 Oracle introduced the new version of Visual Builder Cloud Service. This version is not just aimed at the Citizen Developer, in the end an experienced JavaScript can do nice things with it.

In this blog I will have a look at 5 of the 6 main building blocks you build a VBCS applications with:

  1. REST service connections
  2. Flows and Pages
  3. Variables
  4. Action Chains
  5. UI Components

Putting all of this in one blog (more...)

Running Kafka, KSQL and the Confluent Open Source Platform 4.x using Docker Compose on a Windows machine

image

For conducting some experiments and preparing several demonstrations I needed a locally running Kafka Cluster (of a recent release) in combination with a KSQL server instance. Additional components from the Core Kafka Project and the Confluent Open Source Platform (release 4.1) would be convenient to have. I needed everything to run on my Windows laptop.

This article describes how I could get what I needed using Vagrant and VirtualBox, Docker and Docker Compose and (more...)

Enhance Vagrant provisioning: install java and database

In my previous blog posts (here and here), I wrote about how to create a base box and a create and start a virtual machine out of it. I started with provisioning, to have the vagrant user adapt the kernel settings, add a install user/owner and create a filesystem on an added disk.

Now let's make the provisioning a bit more interesting and install actual software in it.

Prepare new Vagrant project

Installing haveged from Oracle repositories

In my previous blog, I mentioned the installation of the utility Haveged that is used to increase your entropy on non-gui systems. Since you can download it from the Oracle yum repository, I figured that I could install it from yum too, instead of using rpm. This prevents me from having to download it myself, and ensures I have the one that is applicable to my version of Linux.

Too bad it isn't (more...)

Base box ready? Let’s create a box!

Last week I wrote about creating our own Vagrant base box, based on the new and fresh Oracle Linux 7 Update 5. As a reaction on my article I got noted that Oracle also keeps base boxes for their latest linuxes at http://yum.oracle.com/boxes. They're also a great start.

To begin, I created a project structure for all my vagrant projects:
As you can see, I have a vagrant main projects folder on my (more...)

Oracle Linux 7 Update 5 is out: time to create a new Vagrant Base Box

It's been busy, so unfortunately it's already been almost two weeks I wrote my introductory story on Vagrant. Today I happen to have an afternoon off, and I noticed that Oracle Linux 7 Update 5 is out. I based my first boxes on 7.4, so nice moment to start with creating a new Base Box.

De essentials on creating a Vagrant base box can be read here. But I'm going to guide you trough (more...)

Garbage First in JDeveloper

At my current customer we work with VDI's: Virtual Desktop Images, that at several times a day very, very slow. Even so slow that it more or less stalls for a minute or two.

JDeveloper is not known as a Ferrari under the IDE's. One of the causes is that by default heap settings is very poor: 128M-800M. Especially when you use it in  SOA or BPM Quickstart then at startup it will need to (more...)

Epilogue

The AppsLab experiment ended this week as nearly all of us were laid off from Oracle.

Noel and I decided to keep this blog running, both as a historical resume of sorts and as a way for all of us who worked in ‘Lab over the years to share our ongoing adventures and talk about technology.

We had a good run, thanks to executive leaders like Paul and Jeremy, and I will always remember the (more...)

The vagrant way of provisioning – an introduction

About 2003, I guess, I was introduced into VMWare by a colleague. I was hooked about right away.
Since then I made numerous VMs for as many purposes. I played around with several VMWare products, but since Oracle acquired Sun, I stuck with VirtualBox.

A few years ago the tool Vagrant was mentioned to me. But I did not get the advantage of it, since all I needed to do I could do using VirtualBox.

PaaSForum and the talk with the two ladies…

It's already been a week or three that I've been to the excellent PaaSForum '18 in Budapest.
Much is already said and written about it. About the talks and breakout sessions.
To see and hear about the state of art of the Oracle PaaS products: every year I'm having a good time with Oracle Friends around Europe and beyond.

It was nice to play around with API Management, Dynamic Processes, Oracle JET and ChatBots. And, ... (more...)

SQLDeveloper: User Defined Extensions and ForeignKey query revised

It was so fun: yesterday I wrote  a small article on creating a query on Foreign Keys refering a certain table. A post with content that I made up dozens of times in my Oracle carreer. And right away I got 2 good comments. One was on the blog itself.

And of course Anonymous is absolutely right. So I added 'U' as a constraint type option.

The other comment was from my much appreciated (more...)

Which tables have foreign keys refering to a particular table?

Ok, this time a quick not so exciting post. Actually, I find my self recreating a query again, that I created many times in my carreer. So, why not post it?

Last year, I published my Darwin Object Type Accelerator (Dotacc). It allows you to generate objects from a datamodel. What it also does is create collection types for tables that refer to the tabel you want to generate an object for. For some you (more...)

Exploring AR

Since back in 2015 when we got the Not-For-Sale developer model of Samsung Gear VR Innovator Edition which only works with Samsung Note 4, we started to set our eyes on the development of immersive digital media experience of virtual reality.

The original Gear VR in 2015. Feels so ancient ????

Along the way, we have researched on enterprise VR use cases, device platform, and development technologies. We created virtual gadget lab as soon as A-Frame (more...)

Research on Emerging Tech Like AI, IoT Aims to Make Your Work More Efficient

Cross-posting this bit I wrote for the official Oracle Application User Experience blog, enjoy.

Recently, at Oracle CloudWorld in New York, Oracle President Thomas Kurian talked about how emerging technologies can change the way you do your job for the better.

Investigating this impact is the primary focus of the AppsLab, the Oracle Applications User Experience (OAUX) Emerging Tech team, and it is what my team and I explore every day.

Set the minimum password length on your default authenticator in Weblogic

End of last year I wrote how to create a demo community of users in your Weblogic using wlst.
Using these scripts I wanted to do the same at my current customer: creating test users in the DefaultAuthenticator. However, I faced that the minimum password length was 8, while one of the user failed creation, because the password was the same as the user, and only 5 characters long.

So I need to change the (more...)

Weblogic 12c + SAML2: publish your metadata over an URL

This week I got to do a SAML2 implementation again for APEX against ADFS. Actually the same setup as last year. One pitfall I fell into with open eyes, was the Redirect URI on the 'Web SSO Partner Provider'. I entered /ords/f*, but it had to be with out the wild-card: /ords/f. But that aside.

At one step in the setup of a SAML2 configuration is that you have to publish the metadata, by (more...)

How to install the Notepad++ 64-bit plugin manager

I'm a Notepad++ fan for years. And as soon as a 64-bit version arose I adopted it.
But since a few months I have a new laptop, and I apparently didn't get the plugin manager with the latest new install.  And only now I took the opportunity to sort it out and write about it.

I found that the plugin manager is available since April 2017 on GitHub, version 1.49. I downloaded the (more...)

Shoe Treads

In December our team was allowed two weeks to pursue a “passion project”. It didn’t have be work-related, just something you truly wanted to work on. I chose to design tread patterns on the soles of shoes.

I had never given a thought about shoe treads until, a week earlier, a woman on the NodeBox forum asked for help creating organic shoe patterns. I asked her to elaborate on what she meant by “organic” and (more...)

SoapUI: validate a date field in response with current date

Once in a while you need to validate a service that has dates in the response. Although SoapUI has xpath and xquery match assertions, validate against strings is quite difficult. How to do a date comparison against for instance the current date?

You can do it with a script assertion:
And the content of this can be:
def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
// Set Namespaces
def holder = groovyUtils.getXmlHolder(messageExchange.responseContent)
