BPM BAC Subversion Server refusing connections Revised

A little background

In April I wrote about our BPM Server installation, that is actually a single host cluster on dev and test. But installed like it was a dual-node  server, so we had a cloned domain.

A BPM installation has a component that is called the Process Asset Manager. Under the hood it uses a replicated SubVersion server. Each node has one, so they had to synchronize. But since we're on the same host, (more...)

SOASuite 12c: keep running instances using ANT

At my current customer I implemented a poor man's devops solution for Release and Deploy. It was based on a framework created as bunch of Ant projects, that I created years ago. It was based on scripts from Edwin Biemond. See for instance here, here and here. I never wrote about my solution, because although I refactored them quite intensively, the basics were already described thoroughly by him.

What I did was that I (more...)

Enable WebService test client on SOA/BPM production mode environments

At my current assignment I need to trouble shoot the identity service because of a BPM->OID coupling. I use the support document 1327140.1 for it, that suggest to test http://<soa-server>:<port>/integration/services/IdentityService/identity

Doing so in a production mode soa or bpm environment, you'll soon find out that it uses the WebService test client via uri /ws_utc, and that this does not work. Resulting in http-404 Not found errors.

First I found a blog of Maarten of Amis (more...)

Jeremy on the Role on Emerging Technology

Here’s a video from our Group Vice President, Jeremy Ashely (@jrwashley)  about Emerging Technology and how it should be helping people to use the system. This is a nice, concise description of what we do and why.

IoT Cloud Brewed Beer @ OOW: The Details

Now that Oracle Open World has come and gone, I have some time to go into the details of how this project was conceived and realized, and how it faired at OOW.  Let’s start with that last one.

I guess to no one’s surprise, the actual booth with (free!) beer was a crowdpleaser;  we blew through the stock of 12 kegs with time to spare.

IoT Workshop and Robots

AppsLab has been offering the IoT Workshop since Oracle OpenWorld 2016. And over past one year we have hosted the workshop in 20 cities around world as part of Oracle Code events, plus at Kscope 2017 conference. And if you still managed to miss all the events,  Oracle OpenWorld 2017 might be your last chance ????

In this post I will simultaneously have Fun With Data and Fun With Maps. I will use public APIs to turn my Isle of Alameda into a “choropleth“, a map which displays areas that are colored or patterned in relation to data.

To do this I will need to find boundaries within Alameda that I can associate with data of some kind. For this I turn to the ultimate source of geographical data (more...)

IoT Cloud Brewed Beer @ OOW

For the past few months we have worked together with the Oracle Developer Community and Alpha Acid Brewing on a secret IoT project.   Come see (and taste!) it at the Developer Lounge in Moscone West during Oracle Open World.

Hope to see you there!

Oracle Code – Recap

Oracle Code 2017

March 1, San Francisco, USA – August 30, Seoul, South Korea
183 days (exactly 6 months), 20 cities around the world
thousands of speakers, OTN staff and local consultants
hundreds of thousands of participants and coders

That’s the Oracle Code 2017 tour, presenting current and upcoming technologies in packed sessions, providing Oracle cloud services lab for hands-on experience, and a relaxing and fun Code Lounge to be inspired! It is a large (more...)

The Isle of Alameda

The best way to learn how to make your own maps is to map someplace familiar. The place I live, Alameda, is an island in the San Francisco Bay, but existing maps don’t do it justice.

So as part of my Fun With Maps project I set out to disentangle Alameda from the urban sprawl that surrounds it and, using open source data, make a cleaner map that captures the windblown isolation of a real (more...)

Implementing the KeyStore Service with Fusion MiddleWare 12c

For the passphrases, use the passphrases used earlier.Thinking about TLS (Transport Layer Security, the succesor of Secure Socket Layer, SSL) and WebLogic and Oracle HTTP Server, allways gave me Cold Water Fear. You have to create keystores with keys, wallets, certificate signing requests, import signed and trusted certificate chains. Not to mention the configuration of WebLogic and OHS.

Now, creating keystores with the Java Keytool turns out not that hard. And generating the Certificate (more...)

Welcome NAO

On a quiet Thursday morning, I went to our Gadget Lab at Oracle HQ and turned on the light. Inside the comfy egg shell chair sat an NAO robot, waiting for me.

Welcome NAO, our latest team member!

NAO is a little adorable humanoid robot created by SoftBank Robotics. It can talk, walk, and dance; it can read stories to babies; it can have a conversation with adult human…… (more...)

Fun With Maps

Maps are one of the oldest and most powerful forms of visualization. Lately I’ve been learning how to make my own maps using open source data and public APIs.

I started by simply plotting locations on a world map. World maps in svg format are readily available on the web. Wikimedia Commons, for example, has free maps in a variety of formats. The simplest is an equirectangular projection.

It’s dirt simple to plot locations on (more...)

Heading ‘into the wild’ for guerilla research on emerging tech

The OAUX Emerging Technologies team, or The AppsLab, researches technical innovations coming down the pipeline. Part of our goal is to assess the potential of the technology – is it easy to adopt? Are there use cases that might make work easier for enterprise employees to complete their tasks?

Our research on emerging technologies finds three ways to enhance the user experience: Automate tasks to increase efficiency, advise customers on the best practices based (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:
