In distributed processing with SESAM/SQL-DCN, an application program can work with more than one SESAM/SQL DBH during a single session. The application program can work with the different DBHs within the same configuration, in more than one configuration on the same computer, or in more than one configuration on more than one computer. Cross-computer interaction between the application and different DBHs allows the application program to access databases located on other computers. Here, one refers to distributed databases.
In distributed processing, the computers involved are referred to as home or remote computers. The terms “home” and “remote” refer to the application program's view of the system.
Home computer
The computer on which the application executes is referred to as the home computer.
Remote computers
In a computer network, all computers other than the application's home computer are referred to as remote computers.
