IoT Workshop Guide – part 1

AppsLab and OTN will jointly host IoT Workshop at Oracle OpenWorld and JavaOne conference in 2016. We look forward to seeing you at the Workshop.

Here is some details about the Workshop with step-by-step instructions. Our goal is that you will learn some basics and get a glimpse of Oracle IoT Cloud Service at the workshop, and you can continue playing it with IoT package after going home. So be sure to bring your computer (more...)

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...)

…. 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...)

Basis Peak Recall: Wearable Tech Grows Up and Gets Burnt

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...)

Notes on vendor lock-in

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.
  • Your applications can’t run (more...)

Set connection retry frequency on DataSource in WebLogic 12c.

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...)

Start and stop a WebLogic (SOA/OSB) Domain

So let's start the day with a blog. In the past few months I created scripts to install FMW products and build a WebLogic domain for it. For most of my findings I did a blog already:

Create WebLogic users for ServiceBus 12c

Last week I wrote a blog about how to create WebLogic users for ServiceBus 12c. However, I did not now how to assign a particular Application Specific Role to the weblogic user, for particular ServiceBus privileges. I did find out what particular Roles there were (see the blog). But how to assign them I found out just today.

So here it is:

Reset your Datasources

In most SOASuite and Oracle ServiceBus projects the Database Adapter is used. And often it is used to invoke PL/Sql functions and procedures. Actually, it's my favorite interaction method with the database, since the re-entrancy of the database adapter wizard is best there. To do a re-entrant update of a select or DML operation when for instance a column is added, is simply put often quite problematic.

But the thing is with Pl/Sql that when (more...)
