Map definition file

The mapping definition file contains mappings that define how the gateway maps data received from the ObjectServer to the destination data collecting application.

You can configure the mapping functions of the gateway by using the mapper properties defined in the G_MESSAGE_BUS.props properties files.

For details of these properties, see Mapping properties.

Running the gateway

The default map definition file, message_bus.map, is located in the following directory:

$OMNIHOME/gates/message_bus

Information flow

The gateway is comprised of mapper, reader, and writer components. The flow of information between the components is as follows:
  1. The reader component reads from the source ObjectServer and passes the data to the mapper component.
  2. The mapper component converts the data it receives into an appropriate form for the target writer using the map definition file. It then passes the data to the writer component.
  3. The writer component writes the data it receives to the destination data collecting application.
