I am interested in this project as I have enough basic knowledge about
apache axis2, apache ODE, WS-BPEL and I am currently studying those. So I
appreciate if you can provide more details on project.

Hi,
I checked the behavior of ODE using two tomcat servers when deploying same
HelloWorld2 sample. Following are the things I could observe.
-
deployed HelloWorld2-1 in Tomcat-1 server → Active state
-
deployed HelloWorld2-2 in Tomcat-2 server → Active state
-

Hi,
This is my plan on implementing ODE clustering using hazelcast. I thought
to use a static configuration. Each node has a config file which stores
hostName and port number of each node in the cluster. So each node is aware
of other nodes in the cluster and when a node start up it will join to t
Hi,
In the cluster, every node shares the database and deployment directory. To
avoid race condition I am going to introduce master and slave
configuration. Here master node will deploy the process and write the
version number to the database. Until master node finishes its process all

Hi Tammo,
The master node writes meta data. But runtime information must be available
in all nodes.Since the folder is shared, all nodes will see the
availability of a new process. My idea is for master node to write the meta
data and other nodes to just read the meta data and load process.So we n
Hi Tammo,
I thought to use WKA implement the cluster, not multicast or aws. What do
you think?

Hi Sathwik,
I will concern your approach. Thank you for your effort.

rying to release the lock for

Is this possible? But there were not any conflicts while deploying. It
worked perfectly.
Thank you

Hi Sathwik,
I modified the code as you explained. You can go through the code by
following link.
https://github.com/Subasinghe/ode/tree/ODECluster
It would be helpful if you can provide a feedback on this.
Thank you.

Hi Sathwik,
I modified the code and tested it with two nodes cluster. Deploying and
undeploying processes works fine except few things.
1 ) Some times the poller is stuck due to the lock.
2 ) After using hazelcast 3.5 it does not take existing hazelcast.xml
Can you help me to solve these things
and then use putIfAbsent.
