Introducing the Open Enterprise
Management Server
The OEM Gateway (OEM) provides client applications with an encapsulated interface
layer to enterprise management frameworks.
The OEM consists of a Server component and one or more Adapter components. Client
applications communicate with the Server component. The Server communicates with
the Adapter or Adapters on behalf of the clients, while the Adapters handle
communication to and from the enterprise management framework.
Interfaces are implemented as ActiveX OLE servers/components. ActiveX minimizes
the impact and effort required to integrate existing clients. The interface provides clients
such as Compaq state monitoring, performance monitoring, and command and control
graphical user interfaces (GUIs) with a simplified, encapsulated layer to operations
management frameworks.
The OEM layer handles all details of the interface to enterprise management
frameworks. As a result, clients effectively communicate information in a uniform and
consistent manner with minimal impact to existing code.
OEM Architecture
The Open Enterprise Management architecture allows clients such as the Compaq
Availability Statistics and Performance (ASAP) monitor to communicate with
Enterprise Management frameworks through a standard ActiveX interface. As a result,
client applications do not have to be framework aware.
Conversely, framework commands are sent back to applications through callbacks to the
OEM, with the OEM routing these commands to the appropriate client by encapsulated
state arbitration. The clients themselves are not required to have knowledge of the
proprietary callback formats of any given framework; the OEM translates callbacks
from all frameworks to a standard OEM command format.
Clients need only integrate with the OEM Server to participate in any management
framework. The OEM Server and framework adapters are responsible for all routing and
translation functions.
