Use case in karaf-cellar
Hi
I am successful in identifying the nodes using karaf-cellar.
Now i want to test or use the clusters.
If one cluster got failed, then it should move to another cluster.
Suggest for a use case. Simple use case such that i can test the clustering
functionality .
Regards
Guru

FYI,
the transport layer, a camel-cellar endpoint, etc are in the Cellar roadmap.
Any contribution is welcome to help us on that ;)

Depending on your requirements and timeframe you have available you have two
options:
As Charles already said: fabric is opensource and has commercial support (if
this is what you're looking for)
Option b is (if you have some knowledge and time to share) to implement
clustering into cellar. While it is not implemented now cellar has the
potentials to do fallback and clustering;
So, as your time allows :-)
Kind regards,
Andreas

Re: Use case in karaf-cellar

Hi Guru,
If you need this kind of support, then you must considering using Fuse
Fabric and fabric-camel by example. More info here :
http://fabric.fusesource.org/
I have created an example showing How to deploy a project using
Zookeepeer on 3 differents Karaf instances (= zookeeper agent) and
camel fabric allows to loadbalance requests between the agents.

Hi Guru,
I think we can bring it to one point for clustering right now.
Cellar as it works right now is meant for "farming" so you are able to
replicate the
installation state in your cluster.
Right now there is no support for Session Failover as you might have expected.

Hi Guru,
As explained by Jean-Baptiste, Karaf Cellar is not at a loadbalancer
nor a fault tolerant solution. Cellar is able to define features,
bundles, properties to be deployed on Karaf instances which are part
of the cellar but Cellar is not able to redirect request to another
cellar instance if one node death. Please, remember, what I explain to
you in a previous email.

Hi Jean,
I obviously experienced it. Let me explain you what i did.
I installed karaf and added camel, camel-blueprint to it.
I deployed a simple use case in three cluster ( karaf-cellar installed ).
When i killed the root node during the process of the use case. then i
noticed the process was not assigned to other cluster.
Regards
Guru

Hi Guru,
you can take a look on the Cellar manual:
http://karaf.apache.org/manual/cellar/latest-2.2.x/user-guide/index.html
For instance, if you install a feature on one node using:
features:install eventadmin
this feature will be installed on all node members of the same cluster
group.
If you stop one node (or the node falls down), the feature remains
installed on the others nodes.
Regards
JB
