1 - About

The Heterogeneous Services component (gateway) in the database communicates with the Heterogeneous Services agent process. The agent process, in turn, communicates with the remote database.

The code can be conceptually divided into three parts:

  • The Heterogeneous Services component in Oracle Database : This module performs most of the processing related to heterogeneous connectivity.
  • Agent generic code : This is code in the agent that is generic to all Heterogeneous Services products. This code communicates with the database and provides multithreading support.
  • The driver : This module communicates with the non-Oracle system. It is used to map calls from the Heterogeneous Services to the native API of the non-Oracle system, and it is not specific to Oracle systems.
