Lange hat’s gedauert, aber seit heute kann man sich das Debian-Paket für OMD-1.00 vom ConSol-Labs-Repository herunterladen.

root@raspberrypi:~# apt-get install omd-1.00

Die Maschinen unserer Kunden, auf denen wir uns tagtäglich bewegen und Monitoring-Systeme betreiben, haben üblicherweise CPUs und Gigabytes im zweistelligen Bereich. Da wird es schon zur Geduldsprobe, wenn ein Build auf dem Raspberry Pi den halben Tag braucht. Ein ARM11 ist eben kein Xeon und SD ist nicht SSD.

Infinispan is included in the JBoss AS 7 distribution as the default second level cache for Hibernate.
For my presentation on the JBoss One Day Talk 2013,
I was looking for the most simple example to be used in a demo.
This post shows how to get Infinispan Hibernate 2nd Level Caching up and running in five minutes.
It should also work with the upcoming WildFly Application Server.

Changing major releases on linux is always a risk, but Debian / Ubuntu dist-upgrades really worked fine the last years. If you are using OMD (Open Monitoring Distribution) for Nagios/Icinga/Shinken, then the release-update would disabled 3rd party repositorys and therefore remove your OMD installations during the update. This is usually not what you want, but with a small trick, updates work smoothly.
