1.4.2 Operand priorities

If the same operand is defined in different definitions, HiRDB determines the value to be used on the basis of the priority order of the definitions, as shown below:

  1. Single server definition, front-end server definition, dictionary server definition, back-end server definition
  2. Server common definition
  3. Unit control information definition
  4. System common definition

A standard value can be specified in a definition that has a low priority, and then that value can be changed by specifying a different value in a definition with a higher priority.

If an operand is omitted from all definitions, the default value for the lowest priority definition is assumed.
