Here is a great read on “Day 2 problems in the Cloud“. Day 2 is a management problem, not a (more...)

Java 9: JDK without subfolder JRE

In older JDK releases the directory structure was:
bin
db
include
jre
lib
With JEP 220 the jre folder was removed.


A JDK image no longer contains a jre subdirectory, as noted above. Existing code that assumes the existence of that directory might not work correctly.
But this does not mean that there is no JRE any more. You can still download the JRE. There are some minor changes to the JRE like:

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...)

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:

  • 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...)

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

Well as I prepared my demos for Messaging Cloud for the UK Oracle User Group Tech 17 Conference I discovered that (more...)

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...)
