A unit control information definition defines information about a unit. This section explains the formats used to specify the operands of a unit control information definition. Note that the numbers in the following table correspond to the numbers assigned to the explanations of the individual operands in 3.2 Operand explanations.

For users who are creating HiRDB system definitions for the first time

The first step is to determine the values to be specified for the operands shown in boldface type. In principle, HiRDB can be started once the boldface operands have been specified.

For users of the standby-less system switchover (effects distributed) facility

When you use the standby-less system switchover (effects distributed) facility, you can specify only certain operands. For details, see F. List of Operands That Can Be Specified When Using the Standby-less System Switchover (Effects Distributed) Facility (Unit Control Information Definition).
