Presentatie Agile schalen op basis van best practices

Presentatie Agile schalen op basis van best practices

Net als de afgelopen jaren heb ik afgelopen vrijdag een presentatie over Agile Architectuur gegeven. Kern van de presentatie dit jaar is dat bij het schalen van Agile vooral de problemen/uitdagingen die je onderweg tegenkomt aangepakt moeten worden en niet klakkeloos een framework gaat implementeren. Aan de hand van voorbeelden leg ik uit hoe we dit binnen bol.com aanpakken.

Controlling Oracle WebLogic Server via RESTFul Management Service

RESTFul Management Services are really powerful in terms of monitoring your Oracle WebLogic Server Domain, but you can also use RESTFul Management Services to control your Oracle WebLogic Server Domain.

RESTFul Management Services are enabling you to startup, suspend, resume and shutdown for example your Managed Servers.

All what you need is cURL, the Admin User and Password of your Oracle WebLogic Server, Hostname of your Oracle WebLogic Domain and the Port of your AdminServer.

Oracle Maven Repository in Nexus, authentication failure

Short overview of some last week failing builds at our site 😉

Since a while ago it’s possible to register proxy repositories in Nexus based on the Oracle Maven Repository.
To be able to proxy this repository you need to make use of an oracle account for the autenthication before you can download the artifact.

Let’s check the logging to understand what it does (i can rephrase the logfile or just copy/paste it ;), when others (more...)

Book – Holacracy

Book – Holacracy

HolacracyIk kwam een mooie samenvatting van het boek Holacracy van Brian J. Robertson tegen. Eerder schreef ik een review over Getting Teams Done. Waarin holacracy (en de variant Spark) beschreven wordt als een methode voor teamproductiviteit, net als GTD dat is voor individuele productiviteit. Mijn ervaringen met de holacracy variant Spark beschreef ik in deze post.

De case die vaak gegeven wordt als holacracy adoptie beschreven wordt is Zappos, maar er zijn (more...)

Running Oracle HTTP Server 12c with Privileged Port

In some cases you need to configure a privileged port (less than 1024, typically port 80) within your Oracle HTTP Server 12c Instance.

At first create your Oracle HTTP Server Instance with the wlst tool:

cd $ORACLE_HOME/oracle_common/common/bin
./wlst.sh

Modify Fusion Middleware Enterprise Manager Inactivity Timeout

Are you tired of the 45 minutes default inactivity timeout setting of the Oracle Fusion Middleware Enterprise Manager?



You can simply set the inactivity timeout by modifying the emoms.properties file of the Oracle Fusion Middleware Enterprise Manager.

Connect to your server with the oracle installation user and navigate to your $DOMAIN_HOME/config/fmwconfig/servers/<AdminServerName>/applications/em/META-INF directory and open the emoms.properties file.
Check if the parameter oracle.sysman.eml.maxInactiveTime is set, if yes modify the provided values (more...)

Debian dist-upgrade: Laptop suspends 30s after boot / startup

After i moved to jessie (Debian 8) my laptop moved to suspend to RAM about half a minute after startup.
There was no message in the logfiles and even worse the resume does not work at all...
The configuration for the suspend was in here:
/etc/systemd/logind.conf:

#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root

Approaches to Consider for Your Organization’s Windchill Consolidation Project

This post comes from Fishbowl Solutions’ Senior Solutions Architect, Seth Richter.

More and more organizations need to merge multiple Windchill instances into a single Windchill instance after either acquiring another company or maybe had separate Windchill implementations based on old divisional borders. Whatever the situation, these organizations want to merge into a single Windchill instance to gain efficiencies and/or other benefits.

The first task for a company in this situation is to assemble the right team (more...)

Debian dist-upgrade: ipw2200 firmwares missing…

After the dist-upgrade the ipw2200 wireless chipset drivers are missing.
Grrrr...
No more internet access - so i had to use a good old LAN cable ;-)

The fix was very easy:
apt-get install firmware-ipw22x00
rmmod ipw2200
modprobe ipw2200
 and the wireless network is up again...

Consider Your Options for SolidWorks to Windchill Data Migrations

This post comes from Fishbowl Solutions’ Associate MCAD Consultant, Ben Sawyer.

CAD data migrations are most often seen as a huge burden. They can be lengthy, costly, messy, and a general road block to a successful project. Organizations planning on migrating SolidWorks data to PTC Windchill should consider their options when it comes to the process and tools they utilize to perform the bulk loading.

At Fishbowl Solutions, our belief is that the faster (more...)

HotSpot JVM garbage collection options cheat sheet (v4)

After three years, I have decided to update my GC cheat sheet.

New version finally includes G1 options, thankfully there are not very many of them. There are also few useful options introduced to CMS including parallel inital mark and initiating concurrent cycles by timer.

Finally, I made separate cheat sheet versions for Java 7 and Java 8.
