Oracle Mobile Cloud Service (MCS) and Integration Cloud Service (ICS): How secure is your TLS connection?

In a previous blog I have explained which what cipher suites are, the role they play in establishing SSL connections and have provided some suggestions on how you can determine which cipher suite is a strong cipher suite. In this blog post I’ll apply this knowledge to look at incoming connections to Oracle Mobile Cloud Service and Integration Cloud Service. Outgoing connections are a different story altogether. These two cloud services do not allow you (more...)

PCS and Correlations: the next big thing cavemen already used…

You can use BPM, BPEL or Workflow to orchestrate or direct regular processes to get a job done from the beginning through a certain flow with a few decision-points, alternate and parallel flows to the end. A common use that is fine and usefull for most projects. And it can be seen as the driver for software companies to develop process/workflow engines.

However, there are cases that one process spawns off multiple other process instances (more...)

Process Cloud Service and how to loop and select elements from a list

For more than half a year I've been 'dying' to write posts about some of the constructs I've developed in my last Process Cloud Service project. At last I have the opportunity. And I hope I'll be able to write some more. But for starters, one of the problems I encountered is that I needed to process a list of something(s) and select elements from it. Or even better, how to build up a new (more...)

Weblogic log level mapping

For quite some time now I wondered about the differences in log-levels. For instance, if you configure the log levels in the classes in SB12c or SOA Suite,  You see levels as INCIDENT , ERROR, and TRACE, even with several sub leverls (1, 16, 32). But on the Server Log configuration in Weblogic, you see levels a s ERROR, NOTICE and DEBUG, or TRACE.  And then in Java, JDK logging we even (more...)

OHS URL Rewrite

First half of this year I did two SAML2 implementations on Weblogic. One of those was to implement Single Sign On against ADFS for Apex applications.

In short, we installed an adapted version of ORDS on a Weblogic server and configured SAML2 for Service Provider initiated SSO, as can be read here.

We added an Oracle HTTP Server as reversed proxy to the story. For the other customer I found out how to create a (more...)

How do we build for the future?

How do we imagine and build a solution for the future that screams,

I want to live in a future where this thing exists and is used by people.

Recently, the Appslab Team attended the Future Summit SF where we learned how we could better design and build experiences for the future. We saw an inside peek from how companies such as IDEO, AirBnB, Netflix, Lyft and Facebook design to solve complicated user needs in (more...)

Oracle Linux: Clean Yum dbcache

These weeks we provide a course on Weblogic 11g and 12c Basic and Advanced Administration and Tuning & Troubleshooting. We use an Oracle Linux 6 VM with a Database and Weblogic 11g and 12c.

We got some complaints (issued in a friendly way, by the way) from the attendees that a filesystem of the VM got filled up.

One of the attendees found out that the following folder containt some very large files:
/var/cache/yum/x86_64/6Server/public_ol6_latest

Kscope GO and IoT Workshop at Kscope17

Kscope17 is just around the corner and it is not a secret that we love ODTUG‘s Kscope since it is a conference geared towards Oracle Developers. This year as we have done in previous years, we worked closely with the conference organizers to bring a unique fun experience. We developed an Augmented Reality game called Kscope GO. The concept of Kscope GO should be familiar to all, since last summer the world saw an unprecedented success (more...)

It’s Been 10 Years

Ten years ago, Paul posted a brief introduction to our team and our mission.

He, Rich and I embarked on this journey in March 2007, soon to be joined by Anthony, and none of expected to be around as a team for more than 18 months max.

Maker Faire 2017

Introduction

Another Maker Faire has come and gone, the 12th one already.  Unlike last year, Oracle had a booth again at the Maker Faire, staffed by my colleagues and myself throughout the weekend, where we showed of some fun demos.  Here are some impressions, both from reactions in our booth and from the grounds.

HTTP Server redirects for Weblogic 12c and SAML2

Last few months I got busy with SAML2 and Weblogic 12c as Service Provider. One with ADFS and another using SurfConext as an IdP.

In both cases a HTTP server is used as a reversed proxy, in one case it is Oracle HTTP Server 12c, in the other we use Apache. Although OHS is based on Apache, of course, it has the Weblogic proxy plugin enabled by default. With Apache this is not the case.

BPEL 12.2.1.2 and UMS: no wire target for reference…

A moment ago I stumbled on this question on the Oracle community. User Saurabh  tries to build a composite to send email from BPEL. But on testing the deployed composite in EM it fails with a remote fault. This despite of a correct configuration of the email driver and being able to test that   using soa-infra -> Service Engines -> Human Workflow -> Notification Management.

He found that the problem was a bug in JDeveloper/SOA (more...)

Introducing Darwin Oracle Type Accelerator


Years ago, I created a set of XSL templates and queries to create object types out of queries on the datadictionary of the Oracle Database. It only did basic types on tables, and selects on those. I wrote an article on it that still can be downloaded here. Later, I extended the framework to also do inserts and updates and follow foreign keys. The thing with foreignkeys is that you can handle them a as (more...)

List Weblogic 12c System Components

Besides starting and stopping servers, it turns out handy to be able to list the particular system components of a Weblogic domain. For most domains, you might have an embedded/colocated Oracle HTTP server.
But we're also busy with installing BI publisher domains, and there several BI Components are created. To list which ones are created (and determine where things might went wrong) it might be handy to list all the system components. For that I (more...)

Single Sign On for Apex with ADFS? With Weblogic 12c and ORDS: Yes, you can!

Lately we implemented a Single Sign On solution for Apex, based on Weblogic 12cR2, ORDS 3.0.9, and ADFS as a federated Identity Provider. This combination turns out to be a marriage of 3 different worlds. So we ran in to a several issues that were not described in one simple how-to document. So in this document I try to assemble the information needed to do the end 2 end configuration (apart from the (more...)

‘No such file or directory’ on starting your domain

Today I was triggered by this question. Earlier I had a similar problem, where I searched, and searched and searched and found the last section on this blogpost. Yes indeed, that is how it works when you blog: you might find your self finding your own blogposts again.

What is it about? Last year I wrote a nice set of scripts on installing Fusion Middleware and creating Fusion Middleware Weblogic domains.

I created the domain-creation-script (more...)

New and improved (re-)start and stop scripts for Fusion MiddleWare.

Last year I created a set of start and stop scripts for Weblogic/Fusion MiddleWare. Although I was quite happy with them at the time, I found that there was quite a lot of duplicate code. And I think I could improve them by combining at least the wlst scripts into one, making it a lot better maintainable, but also opening up for restart functionality. And doing so make the scripts more generic. I took my (more...)

BPM BAC Subversion Server refusing connections

These days I work on setting up several development lifecycle environments for BPM, SOA and OSB. What means that we setup servers for Development and test, culminating eventually in supporting the setup of the acceptance and production servers.

Since we want to have development resemble production as much as possible, we installed a dual-node clustered BPM environment, including BAM. However, since it is development, we have the two Managed Servers per cluster on the same (more...)
