Description
What StreamBase Server deployment configuration files do not get included in the application archive ZIP-file but are maintained separately?
Resolution
To install a node for a cluster you need the application archive ZIP-file, a Node configuration (HOCON type = "com.tibco.ep.dtm.configuration.node") and usually also a substitutions file, referenced as so:
epadmin install node nodename=NodeA.BizCluster nodedirectory=/home/bizuser/nodes application=./Biz_App-0.0.1-SNAPSHOT-ep-application.zip nodedeploy=./biznode.conf substitutionFile=./bizsubs.txt
Typically the node management commands are scripted, and the script is also maintained separately.
The Application definition file (HOCON type = "com.tibco.ep.dtm.configuration.application") defines the dataDistributionPolicies which are then referenced by the Node configuration and are important for the functioning of your HA deployment. The dataDistributionPolicies must be consistent for the entire cluster, so are defined within the configuration included in the application archive, but the node configuration may differ for each node and therefore is maintained separately from the application archive.
For version control, these external configuration and script files may be placed in any folder of the StreamBase fragment or application project except /src/main/configurations or /src/main/resources (so they are not automatically used or referenced).
