Prior to DSA 16.00, a separate Viewpoint server was required for each DSC. For example, a customer with production, test, and disaster recovery environments in separate locations was required to have three Viewpoint servers.

DSA portlets installation is no longer tied to a dedicated DSC instance. A single Viewpoint portlet can configure and monitor multiple DSCs. Also both Teradata systems of 16.0 and later and BARNC processes can subscribe to multiple DSCs.

The configuration of the DSC daemons is discovered based on the connection parameters (broker IP, broker port, and connection type).

Currently we only support one DSC server to one ActiveMQ server, you cannot configure one ActiveMQ server to multiple DSC servers.

After installation the configuration for each DSC is available using the BAR Setup portlet.
