In part 1 the basics were explained. In this part II other topics will be treated like virtualizing, engineered systems, SE2, Unlimited License Agreements, Cloud and other stuff. Whenever I can I will link to other posts. Comments or additions are welcome.
The information in this post is not intended to be used as legal statements or sources for negotiations with Oracle. I will be referring to some other documents and blogposts which can and (more...)
Oracle NoSQL Database is an interesting option to consider when you want a schemaless, fast, scale-able database which can provide relaxed (eventual) consistency. Oracle provides a Node.js driver for this database. In this blog I’ll describe how to install Oracle NoSQL database and how to connect to it from a Node.js application.
The Node.js driver provided by Oracle is currently in preview version 3.3.7. It uses NoSQL client version 12. (more...)
I used to spend most of my time — blogging and consulting alike — on data warehouse appliances and analytic DBMS. Now I’m barely involved with them. The most obvious reason is that there have been drastic changes in industry structure:
Many of the independent vendors were swooped up by acquisition.
Oracle and licenses. The general feeling most of the time is that you pay too much for the use of the Oracle products, and it’s not always sure if you are compliant, because of the complexity of the rules. This – hopefully clarifying – blog is part of a small series and is an updated blogpost of one I wrote a few years ago, published on my private website. Since then the (Oracle) world has (more...)
At one of my customers we have quite an impressive domain configuration. It's a FMW domain with SOA, OSB, BAM, WSM, MFT in clusters of 4 nodes. The thing is that when having started all the servers, the console becomes slooooooowwwww. Not to speak of FMW Control (em).
One suggestion is to set the 'Invocation Timeout Seconds' under MyDomain->Configuration->General->Advanced to a value like 2. And 'Management Operation Timeout' under Preferences->Shared Preferences to a value like (more...)
For a project, we are migrating Forms to ADF. There is also a number of reports which are not to be migrated yet. Therefore, we need to keep the users in the database. As we do not want to maintain two user stores, we thought it to be a good idea to create an authenticator in WebLogic to authenticate to the database. There are loads of blog posts / support notes on how to configure (more...)
While working on my Ionic 2 application, I made use of the exif.js library (for extracting meta-data from image files). Some of the key functions in this library are called and passed a callback function that is invoked when the image has been analyzed. From this callback function, I wanted to invoke a function (TypeScript method) defined in my class. Inside the callback function however, I did not have access to the calling context. (more...)
It has been a long standing ambition of mine to create an app that I could run on my iPhone. This weekend I finally realized that ambition – in what turned out to be a surprisingly simple fashion. Using various tutorials, tips from colleagues and the Ionic 2 framework, I created a progressive web app (pure HTML 5) that I can add to the iOS launchpad as what to all intents and purposes feels like (more...)
“Supercharged Perseid Meteor Shower Peaks This Month” – as the very first edition of Daily Minor Planet brought us the news on August 4th, 2016.
First edition of Daily Minor Planet
Daily Minor Planet is a digital newspaper on asteroids and planetary systems. It features an asteroid that might fly by Earth for the day, or one of particular significance to the day. Also it features a section of news from different sources on the topics (more...)
Using wearable tech is not just some emotive fashion statement but a physical commitment to keep something on your body. With smart watches being close to the skin, and all about wellness and fitness, they need to be safe and not present health risks.
Just like any other product there are going to be times that things don’t work out, but with something as like wearable tech if something does go seriously wrong, then (more...)
Gym at Oracle HQ is currently being held by Team Valor. The gym switches hands on average 3x a day.
Crowd at a park playing Pokemon. Most of us have been here for at least 2 hours.
By now, I have played Pokemon GO for 2 weeks and have reached the coveted level 22. Pokemon GO (POGO) is a massively popular mobile game that has been a viral hit. It became the most popular paid (more...)
Vendor lock-in is an important subject. Everybody knows that. But few of us realize just how complicated the subject is, nor how riddled it is with paradoxes. Truth be told, I wasn’t fully aware either. But when I set out to write this post, I found that it just kept growing longer.
1. The most basic form of lock-in is:
You do application development for a target set of platform technologies.
Probably the best way to get to know your users is to watch them work, in their typical environment. That, and getting to talk to them right after observing them. It’s from that perspective that you can really see what works, what doesn’t, and what people don’t like. And this is exactly what we want to learn about in our quest to improve our users’ experience using Oracle software.
Hard to believe it’s been nearly three years since we debuted the Leap Motion-controlled robot arm. Since then, it’s been a mainstay demo for us, combining a bit of fun with the still-emergent interaction mechanism, gesture.
Anthony (@anthonyslai) remains the master of the robot arm, and since we lost access to the original video, Noel (@noelportugal) shot a new one in the Gadget Lab at HQ where the robot arm continues (more...)
I have encountered several times in WebLogic 12c that when the ConnectionPool of a DataSource in WebLogic could not be initialized because due to a connection error or invalid username or password, the server could not be started.
I can't remember having encounterd this problem in 11g, and this week I struggled with it with one of my customers. The perception of the DBA there was that in 11g the server did start up, but (more...)
