Finished workflows can store their state in the so-called Workflow Archive, to keep their data accessible for editors in CoreMedia Studio.

To enable the SQL persistence for this feature, set the application property workflow​.server.​archive.​persistence to sql for the applications Studio Server and Workflow Server. This will trigger archiving of workflows through the SQL persistence layer bound to the Workflow Server.

Supported SQL databases can be found in the document http://bit.ly/cmcc-12-supported-environments.
