Cluster administration

Discover how to administer, monitor and manage a Bonita cluster.
Backing up a cluster
Back up your cluster in the same as you would back up a standalone Bonita system, by backing up the database. You also need to back up the load balancer (see your load balancer documentation for details of how to do this).
Monitoring a process
To monitor a process in a cluster, use the Bonita Applications as usual. The information presented applies to process activity on all nodes in the cluster.
Deploying a process in a Bonita cluster
To deploy a process in a cluster, configure the process in Bonita Studio, and then create a .bar file using the Build option of the Server menu. Import the process .bar file into Bonita Administrator Application on one of the nodes. The process is now available to Bonita Applications on every node in the cluster. The process must be started on one node. Subsequently, instances can be created on all nodes. This means that all nodes have the possibility of running instances of tasks of all processes.
You can also deploy a process using the API, exactly as you would in a standalone system.
Managing your organization in a cluster
The organization data used by Bonita is stored in the database, so only has to be configured once. It can be maintained from any Bonita Application in the cluster.
Troubleshooting
Each Bonita Engine maintains its own log file on the node
You can find it under <BUNDLE_HOME>/logs/bonita.date.log, where date is the date the file is created.
In addition, there is an incident file <BUNDLE_HOME>/logs/tenants/[TENANT_ID]/incident.log (where [TENANT_ID] is the ID of the tenant on which the error occurred) that is used as a last resort to record an error that cannot be handled, such as failure to access the database.
