System Requirements

The DME server runs on Windows and Linux platforms. The minimum specifications recommended for a system with 100 users are outlined in the System requirements document. For an overview of supported client platforms and devices, see Supported Devices.

DME's technical architecture
DME is based on a multi-threaded J2EE application server, running on Linux or Windows and connected with an SQL-based database server. DME acts as a gateway between the DME clients and the corporate collaboration system, which can be Lotus Domino or Microsoft Exchange.

The DME clients (mobile devices) request data from the DME server, which passes their requests on to the collaboration system via the DME Connectors. The results of the requests are passed back to the clients, leaving no confidential information stored on the DME server. Mobile devices connect to the DME server using the secure HTTPS protocol through a mobile VPN network or any other network (GSM, GPRS, 3G/UMTS, EDGE, Bluetooth, WLAN and cable/cradle), guarded by certificates and AES encryption.

The server itself is located in the company DMZ. The client connections are authenticated based on user lookup (through LDAP or LDAPS), and are routed to the collaboration system. From the server, the connection to the collaboration system is made through standard ports: WebDAV (OWA, Outlook Web Access) on Microsoft Exchange, and CORBA (DIIOP) or native "local" connections on Lotus Domino.
DME also features a OMA DM server engine, which establishes a trust between the devices and the DME server (boot strapping the devices), to facilitate e.g. silent installation of software.
