This example creates system definitions for a HiRDB/Parallel Server. The system configuration is shown as follows.
- Both standby and standby-less system switchover facilities are used.
- The units to which the standby system switchover facility is applied are based on a mutual system switchover configuration and inherit IP addresses for client connection only. User server hot standby is also used.
- The units to which the standby-less system switchover (1:1) facility is applied are based on a mutual alternating configuration.
Note that in this definition example, only those operands that are related to the system common definition and unit control information definition are explained.

- Shading indicates the primary units.
- Server name is shown in parentheses.
- Back-end server (bes1) is a normal BES and is also an alternate BES for back-end server (bes2).
- Back-end server (bes2) is a normal BES and is also an alternate BES for back-end server (bes1).
