From rama.rao.p at celstream.com Wed Jun 14 07:58:13 2017 From: rama.rao.p at celstream.com (Rama Rao P) Date: Wed, 14 Jun 2017 11:58:13 +0000 Subject: [jbpm-dev] jBPM 6 Clustering Message-ID: Hi All, This is my first post there.. so, kindly excuse me for mistakes. I am trying to get the jBPM Clustering setup... I am new to the Clustering concepts.. Can someone guide me / point me to a good source of this? I have already tried to follow steps given in below links...but, seem to be little lost on seeing the clustering in action.. http://planet.jboss.org/post/clustering_in_jbpm_v6 https://docs.jboss.org/jbpm/v6.0/userguide/wb.WorkbenchHighAvailability.html what I have today: 1. Zookeeper is running a. Added a cluster b. Added two nodes c. Added resource VFS 2. Installed jBPM (FULL) on two machines (I know in real two instances for clustering may not work out. But just wanted to see things working). a. Configured host.xml for required properties (as mentioned in 2nd link above). 3. Running helix controller. (this is contacting Zookeeper). How do the two instances of jBPM talk to each other? How do they (jBPM instances) share the data?

For authoring, the workbench (using helix / zookeeper) will make sure that any change to the (internal) git repositories (that is holding all your project assets) is distributed in the cluster. For runtime data, you need to make sure you are using the same database. The server instances themselves are stateless, they get and store their information from/in the database for each request. Hope that helps.
