BlueCielo Meridian Enterprise 2018 Administrator's Guide
Understanding the EDM Server service
The main process of Meridian Enterprise is the EDM Server service. It appears as AutoManager EDM Server in the Services applet of Control Panel. This service is responsible for all communication between the different clients with the available databases. All document management logic (including security) is built into this service, so any access to a vault will always have to go through the EDM Server service.
Meridian vaults may be stored in either Microsoft SQL Server or Oracle databases that reside on either the Meridian application server or another server.
The vaults may also be stored in the BlueCielo database format named Hypertrieve. This is a low-overhead, object-oriented database that is optimized for Meridian. This database engine runs in the same process as the EDM Server service and therefore the engine cannot run on a separate server.
