Single-Server Deployment

A single-server deployment consists of Data Assurance (DA) server, and the local agent that comes with the DA server installation installed on a single machine. The local agent connects to database servers for simple comparison.

Scenario	Suggested Deployment	Task
Low network latency between the DA server and database servers Few concurrent comparisons are required Ease of deployment and maintenance preferred over maximum performance	Single-server	Install the DA server component on a single machine. Note: DA server has a built-in local agent that you can use, which provides the same functionality as the remote DA agent. This is easier to setup, but if the network connection between the database server and DA server is slow, this network latency makes the DA jobs run slower. Avoid using the 'external sort' option when DA is installed as a single server deployment, as the embedded local agent must handle all of the sorting work, which may put DA server under excessive strain. Add one or more DA agents to a single-server deployment to create a distributed deployment.
