Hey there, Thanks for the mention Rudiger, Lars work on this is great indeed as he also thoroughly documented how to replicate his setup while on top of it providing all the required materials (source rpms and spec files). I am currently working on "extending" Lars work on the Matterhorn rpm package itself so it can be used for distributed setups on top of All-in-One installs. The direction I'm currently taking of having a single package for all Matterhorn profiles (admin,engage,worker,...)means a modification of the current way of deploying a Matterhorn node with a specific role, so I'd be more than happy to hear what the community has to say in particular Operations/Systems folks tasked with deploying Matterhorn clusters.
At the moment the way to "configure" a Matterhorn node with a particular role is to have the required jars in the right directory (i.e. the one configured in $MATTERHORN_HOME/load/org.apache.felix.fileinstall-matterhorn.cfg) and then they will <emphasis>all</emphasis> be loaded, if for some reason you miss a jar required by the role or worse you have a conflicting jar in that directory your node will be dysfunctional. This might not be as apparent when you are running "mvn clean install -P<profile> -DdeployTo=$MATTERHORN_HOME in particular when you only do it once per host, but in production environments you actually don't want to be running "mvn clean install" on each host,and so through an .rpm or via scp what you end up doing is moving jars around (plus of course configuration). I don't know about the other folks but this approach is not what I'm used to with the distributed/Service Oriented Applications I've dealt with in the past, typically you specify a nodes role through a configuration file/or a GUI option, not by having the right files in the right directory and load everything in that directory. Thus _so far_ my idea is an rpm package that will contain all the jars created by mvn clean install -Padmin,dist,engage,worker,workspace,serviceregistry,directory-db,capture,oaipmh,export,gstreamer-launch-service,directory-cas,directory-ldap,test-load,dist-stub,engage-stub,worker-stub,workspace-stub,serviceregistry-stub,test while the person doing the deployment will have to edit a config file specifying the node role which in turn will assure only the required jars are loaded (currently this can be achieved via felix system.properties). The alternative to this is profile based packages (e.g. matterhorn-1.3.1-worker.rpm) that only contain and install the jars specific to the profile which would indeed be an antagonist to a single rpm package approach, but then I'd be more happy to hear different opinions and reflections on this =) J.
