Configuring Business Rule Deployment

WSO2 Business Rules Manager uses ruleTemplates within templateGroups, to derive business rules from. Each ruleTemplate will have a UUID - that is used to uniquely identify itself. When a ruleTemplate is specified under a worker node; SiddhiApps derived in business rules created out of that ruleTemplate will be deployed in the specified worker node.

1. Go to the deployment.yaml file under <WSO2SP_HOME>/conf/dashboard
2. Deployment configurations for the Business Rules Manager are specified under wso2.business.rules.manager

3. Provide the URL(s) of worker node(s) that is/are available to deploy SiddhiApps, under deployment_configs - in the format <HOST_NAME>:<PORT>

   deployment_configs:
   	- <NODE1_HOST_NAME>:<NODE1_PORT>
   	  <NODE2_HOST_NAME>:<NODE2_PORT>
   

   Eg:

   deployment_configs:
   	- localhost:9090
   	  10.100.4.140:9090

4. List down the UUIDs of required ruleTemplates under each node such that: when a ruleTemplate is specified under a worker node, SiddhiApps derived in the business rules created out of that ruleTemplate will be deployed in that specific node.

   deployment_configs:
   	- <NODE1_HOST_NAME>:<NODE1_PORT>:
   		- ruleTemplate1_UUID
   		- ruleTemplate2_UUID
   		- ruleTemplate3_UUID

   Eg:

   deployment_configs:
   	- localhost:9090:
   	   - sweet-production-kpi-analysis
          - stock-exchange-input
          - stock-exchange-output

5. A rule template can be configured under more than one node, as long as its instanceCount is many

   deployment_configs:
   	- <NODE1_HOST_NAME>:<NODE1_PORT>:
   		- ruleTemplate1_UUID
   		- ruleTemplate2_UUID
   		- ruleTemplate3_UUID
   	  <NODE2_HOST_NAME>:<NODE2_PORT>:
   		- ruleTemplate1_UUID
   		- ruleTemplate3_UUID
   	  <NODE3_HOST_NAME>:<NODE3_PORT>:
   		- ruleTemplate2_UUID
   		- ruleTemplate3_UUID
   		- ruleTemplate4_UUID

   Eg:

   deployment_configs:
   	- localhost:9090:
   		- sweet-production-kpi-analysis
   		- stock-exchange-input
   		- stock-exchange-output
   	  10.100.40.169:9090:
   		- identifying-continuous-production-decrease
   		- sweet-production-kpi-analysis

   Notice that the rule template with UUID sweet-production-kpi-analysis has been configured under two worker nodes. So that, if a business rule is derived from sweet-production-kpi-analysis, the belonging SiddhiApps will be deployed in both the nodes.

6. Specify the username & password, that are common for all the worker nodes

   username: admin
   password: admin

7. The complete deployment configuration for Business Rules will look like the following

   wso2.business.rules.manager:
   	datasource: BUSINESS_RULES_DB
   	deployment_configs:
   		- localhost:9090:
   			- stock-data-analysis
   			- stock-exchange-input
   			- stock-exchange-output
   			- identifying-continuous-production-decrease
   			- sweet-production-kpi-analysis
    	username: admin
    	password: admin
