Optional: Configuring multiple instances of Business Automation Workflow and Workstream Services

You might want to configure multiple Business Automation Workflow server instances to manage different configurations or separate groups of applications. If you are running both Workflow and Workstreams capabilities, it is a good idea to run them on separate server instances. You can have multiple Workflow instances but you can have only one Workstreams instance.

1. Duplicate the Business Automation Workflow sections in the custom resource YAML file for the number of server instances you want, making sure that you set only one instance to host_federated_portal: true.
   This example shows three server instances.

    baw_configuration:
       - name: instance1
         host_federated_portal: true
         service_type: "Route"
         hostname: 
         port: 443
         
         ...
   
         # ----------------------------------------------------------------------------------------
         #  custom configuration in Liberty server.xml
         # ----------------------------------------------------------------------------------------
         custom_xml_secret_name:
         # ----------------------------------------------------------------------------------------
         #  custom configuration in 100Custom.xml
         # ----------------------------------------------------------------------------------------
       - name: instance2
           host_federated_portal: false
           service_type: "Route"
           hostname: 
           port: 443
           
           ...
   
           # ----------------------------------------------------------------------------------------
           #  custom configuration in Liberty server.xml
           # ----------------------------------------------------------------------------------------
           custom_xml_secret_name:
           # ----------------------------------------------------------------------------------------
           #  custom configuration in 100Custom.xml
           # ----------------------------------------------------------------------------------------
       - name: instance3
           host_federated_portal: false
           service_type: "Route"
           hostname: 
           port: 443
           
           ...
   
           # ----------------------------------------------------------------------------------------
           #  custom configuration in Liberty server.xml
           # ----------------------------------------------------------------------------------------
           custom_xml_secret_name:
           # ----------------------------------------------------------------------------------------
           #  custom configuration in 100Custom.xml
           # ----------------------------------------------------------------------------------------
   

2. Repeat the preparation work for each Business Automation Workflow server instance you want.
   For each instance:
   1. Repeat the instructions in Preparing databases and secrets for your chosen capabilities by running a scriptor Creating required databases and secrets without running the provided scripts.
   2. Repeat the instructions in Preparing storage.
   3. Repeat the instructions in Creating secrets to protect sensitive configuration data.
3. Add the newly created database, storage, and secrets information to the corresponding Business Automation Workflow server instance configuration sections in the custom resource.
4. Ensure that each Business Automation Workflow instance has its own object store for content integration. The same content integration object store cannot be used for multiple Workflow instances. Each instance also requires its own Transport Layer Security (TLS) secret.
   You must set different values for these parameters in the custom resource YAML file for each instance:

   • baw_configuration.content_integration.object_store_name
   • baw_configuration.tls.tls_secret_name
   Also ensure that

   • The oc_cpe_obj_store_asa_root_dir_path for each object stores is unique.
   • Each dc_os_label has a related dbusername and dbpassword defined in the ibm-fncm-secret.
   • The oc_cpe_obj_store_conn.name is unique for each object store.
   • Each instance has its own admin secret: admin_secret_name: '{{ meta.name }}-instance1-baw-admin-secret'
5. For all instances except the first one, delete the case subsection, which is the subsection that contains the baw_configuration[x].case parameters.
   • Case Manager supports only one Business Automation Workflow server instance. Make sure you remove all the case-related entries from the other Business Automation Workflow server instances.
   • Workstreams does not support multiple server instances either.
