Docker-CE: How to modify containers with overlays / How to add directories to a standard docker image

After some experiments with docker i wanted to run a tomcat with my own configuration (e.g. memory settings, ports, ...).


The first guess is: Download tomcat, configure everything and then build an image.
BUT: After i learned how to use the -v (--volume) flag for adding some file via the docker command to an image i was wondering, wether creating a new image with only the additional files on top of standard (more...)

Oracle SOA Suite: Installating the Fusion Middleware Infrastructure

After setting up the database (installation, instance setup) and the SOA Suite repository (via rcu) the next step is to install the Oracle Weblogic Infrastructure.

The software can be downloaded here:

(You have to choose "Fusion Middleware Infrastructure Installer)

The unzip the downloaded zip:
 fmw_12.2.1.3.0_infrastructure_Disk1_1of1.zip
and run it: 
java -d64 -jar fmw_12.2.1.3.0_infrastructure.jar
Because the Oracle documentation does not contain pictures of the installer, here the screenshots:










Next step is to run the config.sh to configure the Application server domain.

Weird Logon Redirect Issue

We hit a perplexing issue over the Christmas break at one of our clients. They had a user who could not log in and was getting a redirect issue that we’d not encountered before.

We checked it out, made sure his roles were valid etc and found:

  • all other users could log in without any problems
  • this one account was not working via Single sign-on
  • after resetting his Oracle password and trying that method it (more...)

Review at amazon: Kubernetes: Up & Running

Between christmas and new year i read

The authors state:
"This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency."
I think, yes - this is a practial guide, but within only 166 pages it is far too short to give relevant insights into Kubernetes. There are many commands and YAMLs shown, but the book misses a didactic preparation. Some chapters can (more...)

Docker-Swarm: How to run a mysql database…

After several tests with docker swarm (setting up a swarm, running with more than on master, running a webserver in a swarm) i am thinking about running a mysql database in a swarm.

If you are running a mysql database on one docker host, you have to set up a docker volume, because otherwise data inside the container is gone, if you restart your database container. You can follow this tutorial (more...)

Docker-Swarm: Running with more than one manager-node / How to add a secondary manager or multiple managers

Adding additional masters to a docker swarm is very easy. I just followed the documentation:

On the manager i ran the following command:
alpine:~# docker swarm join-token manager
To add a manager to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-3b7f69d3wgty0u68oab8724z07fkyvgc0w8j37ng1l7jsmbghl-5nrni6ksqnkljvqpp59m5gfh1 192.168.178.46:2377
And on the node:
node03:~# docker swarm join --token SWMTKN-1-3b7f69d3wgty0u68oab8724z07fkyvgc0w8j37ng1

Message Push Listener – Article Update

When I first wrote about Oracle Messaging Cloud we used a service called WebScript.io to make it easy to demonstrate the Message Push Listener. WebScript was essentially what we better know as a Serverless or Functions oriented offering (that is we wrote pieces of code and deployed them without any consideration servers etc). Well as I prepared my demos for Messaging Cloud for the UK Oracle User Group Tech 17 Conference I discovered that (more...)

Karamazov

 Chapter 3  -  Conversations and Exhortations of Father Zosima

(e) The Russian Monk and His Possible Significance.

FATHERS and teachers, what is the monk? In the cultivated world the word is nowadays pronounced by some people with a jeer, and by others it is used as a term of abuse, and this contempt for the monk is growing. It is true, alas, it is true, that there are many sluggards, gluttons, profligates, and insolent beggars (more...)

Oracle Content & Experience Cloud: Document Search

If you read my first post on Oracle Content & Experience Cloud (Oracle CEC), you would have come away impressed with the capabilities and features of the product. Features for organizations to manage and share high-value content that could be used to build content-rich, omni-channel websites. However, as I’ve continued to work with Oracle CEC over the last four months, some features need improvement. Most notably in my opinion, is search. I’ll explain the (more...)

UKOUG 2017


As part of the UKOUG team that delivered the conferences in Birmingham I couldn't feel prouder. The volunteers put a lot of work into all the decisions that need making in the months before and the team work their socks off upto and through the event.

Thank you everyone.

For me, the Sunday was a surreal start to the event. I landed at 04:42 from the APAC Tour  and caught a coach up to Birmingham. (more...)
