Cedar’s Oracle Cloud Day 2016 – Recap

Cedar held its annual Oracle Day in Oracle’s City office last Thursday – it was actually our 6th year of running the event. The attendance was great – just short of 100 – and with 3 streams of content there was plenty to choose from. If you weren’t there, here’s the highlights of the sessions that I attended:

After the opening keynote from Dan Woolstone, Oracle’s James King and myself spoke to a full room (more...)

Integrate Google Maps in a JET 2.0 hybrid mobile application

Last week Oracle JET 2.0 is released. One important feature is hybrid mobile development. A while ago I created an Oracle JET application where Google Maps is integrated.
Now I want to show my current location in Google Maps on my Android Phone. For this I must use the GPS function of my phone.
So let’s start. First create a new JET hybrid mobile application.

After successful creation, we must add the cordova plugin (more...)

2016 OUG Ireland – My Home Event

For the past few years we have had a single day of sessions followed by a second day of a masterclass; Tom Kyte, Maria Colgan etc but this year after listening to feedback from delegates who wanted more content, the event went to two days of sessions.

Oracle JET 2.0 released

Last monday Oracle released JET version 2.0. The most important news in my opinion is that Oracle JET now is Open Source. Also Oracle JET is available on Github here.

There are a lot of new features added to 2.0. On this site there’s an overview of the new features.

One nice feature is that you can generate a hybrid mobile application.

There are some prerequisites before you can develop a hybrid mobile (more...)

A Few of My Favorite Things

As an Oracle WebCenter consultant at Fishbowl Solutions, I have a number of tools that I use that keep me happy and productive. Whether or not you are a software developer, these tools can do the same for you and your business.

 

Slack

Unless you’ve been hibernating for the last year or so, you’ve probably heard of Slack. Haven’t adopted it for your business yet? Here’s why you should.

Oracle Composite – leftover oramds imports

On designtime we use the oramds to develop our processflows in our bpel processes.

Basically the composite.xml part for a bpel process would look like this :

<component name="saveEmployee" version="1.0">
    <implementation.bpel src="BPEL/saveEmployee.bpel"/>
    <componentType>
      <service name="client_ep" ui:wsdlLocation="oramds:/apps/xsd/myapp/1.0/saveEmployee.wsdl">
        <interface.wsdl interface="http://mynamespace.nl/saveEmployee#wsdl.interface(bewaarB2bEmployeeServicePort)"/>
      </service>   

When you open the bpel in jdeveloper, jdeveloper will automatically add the next import to your .bpel file :

  <import namespace="http://mynamespace.nl/saveEmployee"
          location="oramds:/apps/xsd/myapp/1.0/saveEmployee.wsdl"
          importType="http://schemas.xmlsoap. (more...)

Manage your database data with Oracle JET

I want to know more about using CRUD (Create, Retrieve, Update and Delete) in a JET-application.

For this I started with a look in the developers guide. You can download a complete sample application here which is based on the HR-schema in an Oracle database.
In this sample application there are some ID’s shown. I added more functionality to get the sample application more user friendly.

First I changed the JSON-file with the department records (more...)

Last week in Stream Processing & Analytics 2/21/2016

This is the second installment of my blog series around Stream Processing and Analytics. I will now publish by the end of the week (on Sunday evening or Monday evening) that’s why the title “Last week in …” is more appropriate ;-)

This might not surprise you, but I just realized, that it’s just not feasible to have the intention to cover every single news/blog article which is new in this week. I also decided (more...)

Experiences with Holacracy

There is a growing number of books on holacracy. One of the first on this subject without even coining the term was Eckart’s Notes. Also the ones on Semco (like Semco style and Maverick!) are gaining popularity. These all describe case studies, where Reinventing Organisations shows development stages in organization. These in turn are based on literature and case studies like the one that is described in Eckart’s Notes.

A Tip for using Excel to Validate HDL templates

HCM Data Loader (HDL) data ready to load into Oracle HCM Cloud is in pipe separated text file format, however most people will create and manipulate these files in MS Excel as it’s the handy swiss-army-knife for data manipulation that almost everyone is familiar with.

The way that we’ve worked is that we create template files containing the sheets and columns corresponding to the fields that the client is using, which the client then populates, (more...)

Flame Graphs Vs. Cold Numbers

Stack trace sampling is very powerful technique for performance troubleshooting. Advantages of stack trace sampling are

  • it doesn't require upfront configuration
  • cost added by sampling is small and controllable
  • it is easy to compare analysis result from different experiments

Unfortunately, tools offered for stack trace analysis by stock profilers are very limited.

Solving performance problem in complex applications (a lot of business logic etc) is one of my regular challenges. Let's assume I have another (more...)

Holacracy – Spark; Wat ik leerde van Getting Teams Done

Holacracy - Getting Teams Done - SparkHolacracy (en de variant Spark) is een methode voor teamproductiviteit, net als GTD dat is voor individuele productiviteit. De onderliggende principes van Holacracy en GTD komen sterk overeen. Aan GTD ontleent Holcracy de discipline en helderheid van het denkwerk en de gewoontes en vaardigheden die daarbij horen. In Holacracy wordt het denkwerk gedaan en zichtbaar in de overleggen van het team.
