HiRDB/Parallel Server: when the standby system switchover facility is used

This example creates system definitions for a HiRDB/Parallel Server. The system configuration is shown as follows.

Mutual system switchover is used.
IP addresses are not inherited.
The rapid system switchover facility is used for all units.

Note that in this definition example, only those operands that are related to the system common definition and unit control information definition are explained.

Key points

When IP addresses are not inherited, specify a host name using an alias IP address for the -x and -c options of the pdunit operand, and not the standard host name, to maintain independence from the server machine.
When mutual system switchover without IP address inheriting is used, the host name to be specified for the -x and -c options of the pdunit operand must be unique. See the pdunit operand specification example in (1).

Explanation

Specifies the HiRDB port number.
Specifies the operands related to the system switchover facility.
Specifies the unit configuration of HiRDB/Parallel Server:
-x: Host name
-u: Unit identifier
-d: HiRDB directory name
-c: Host name of the secondary system
-p: Port number of the unit
Specifies the server configuration of the HiRDB/Parallel Server:
-t: Server type
-s: Server name
-u: Unit identifier
