I dream of wires. Not

I’m a mega Gary Numan fan. I’ve loved his stuff since the Tubeway Army days (I sometimes use “Are ‘Friends’ Electric?” as a heading on my presentations about smart user experiences) and his records were some of the first I bought.

 One of my favorite Numan tracks is “I Dream of Wires” from the Telekon album. (the song was also covered by the late Robert Palmer). The lyrics tell the story of the (more...)

Garmin vívomove: Style Disconnect

I have been testing the latest Garmin vívomove activity tracker for real. Garmin has pretty much made their high-end wearable devices a no-brainer choice for the hardcore and committed athletics and fitness types, and I already use the mighty Garmin fēnix 3

However, Garmin is also not content to leave the rest of the sports watch market to Fitbit and friends and the activity tracker market is now a large part of their business. The (more...)

Publishing applications to Application Container Cloud Service from Oracle Storage Cloud

This weekend, while preparing for a demo during Oracle OpenWorld 2016, I found a for me new way of publishing a new [version of an]application to Application Container Cloud: through Storage Cloud. The application archive – zip or tar – can be stored on Storage Cloud and the deployment to ACCS can be performed from Storage Cloud. I am not yet sure if this makes for a better automated workflow. What it does give me (more...)

IoT Workshop Guide – part 2

In last p`ost, we have setup development environment for coding and uploading scratches to NodeMCU, an IoT device.

This post, we will upload and run two examples to demonstrate how IoT device sending data into Cloud and receiving commands from Cloud.

It involves several tiers and components to make the whole IoT loop. However, you will just focus on device communication with MQTT, all other components have been setup properly.

You are in trouble when more than 8 kernel options are enabled in oracle executable

A brief headsup for everyone responsible for maintaining kernel options in the oracle executable.

The environment where I discovered this is a 3 node racattack cluster with Oracle GI & RDBMS 12.1.0.2.0. After enabling Unified auditing in my 12.1.0.2 database I noticed that all of a sudden database startup started failing with an almost  unlimited amount of core dump files being generated.

How to solve JSchException Algorithm negotiation fail. And get logging out of JSch in SoapUI.

I was so glad with my SoapUI solution to SFTP files to a server. But so dissapointed I couldn't have it working at my customer.

After I changed the log entries to log with e.message, I got the line:
Wed Sep 07 11:17:43 CEST 2016:INFO:JSchException Algorithm negotiation fail

Now I needed more information than that. But the hint is at least that there is a mismatch in the available cyphers client side verses server (more...)

Use SoapUI to test your SFTP based services

SoapUI is my favorite tool to do unit tests. I'd try to keep my self to test based development and build up tests along with the development service. For SOAP or REST based services this goes quite intuitively using SoapUI. For database driven it is a little harder, but SoapUI has a nice JDBC activity, that supports DML as well as callable statements as stored procedures.

But for files and especially SFTP its a little (more...)

First steps in deploying Node.js on Heroku

Recently, I used Heroku to deploy a website in the great wide open!
In this blogpost I want to tell about my first steps using Heroku, including the rookie mistakes I made: so you don’t have to make them.

Heroku in a nutshell:

“Heroku is a cloud platform that lets companies build, deliver, monitor and scale apps”
You can deploy your NodeJS application (or Rails or..) there with a simple git push.
The app (more...)

Login with OAuth2.0 using AngularJS 1.5 componentrouter and Node

For one of my projects I need my users to log in to an 3rd party api (in my case strava) using oauth2.0
Framework of choice: AngularJS 1.5 in plain javascript, with the Angular 1.5 componentrouter. Since I have apikeys which I do not want to be known the the client, I also need my own mini server using NodeJS, express and a bit of request.

OAuth2 in a nutshell:
Someone wants to (more...)

…. this is only a psuedo object?

Yesterday I was working on a BPEL project that I created before the summer holidays. I wanted to implement it further. But on first redeployment I ran into:

The third one on Creating weblogic user, now for SOA Suite

A few months ago I figured out how to create specific users with restricted access to Service Bus components. I blogged about it in part 2 of creating WebLogic users for ServiceBus 12c. But the series lacks an explanation on restricted user access on SOASuite.

Today in a question about Roles on Oracle Community Forums, the reference to this elaborate blog entry was given: Restricted View, by Antony Reynolds.

I think that blog (more...)

Are analytic RDBMS and data warehouse appliances obsolete?

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:

Mount NTFS disk in Linux 7

Today I wanted to pass an old disk in a usb-case to my son. It was from an old Windows Laptop and even though I'm administrator, I wasn't able to read the documents in an other user's folder.

So I thought, let's do it from an Oracle Linux 7 VM, as root. But it turns out that Oracle linux did not support NTFS by default.

But with the trick in this link I managed to (more...)

Generate Admin Channels to improve Weblogic Admin Console performance (and of FMW-Control)

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...)

Unable to login with a SQL Authenticator

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...)
