8.2 Operands whose specification values can be changed

The values of some of the back-end server definition operands can be changed in the system common definition, unit control information definition, and server common definition. These operands are indicated below. After a planned termination, forced termination, or abnormal termination of HiRDB, some HiRDB system definition operands can be modified while others cannot be modified. The operands that can be modified are indicated below.

Y: Yes, specification value can be modified.

N: No, specification value cannot be modified.

[Figure]: Specification value cannot be modified because operand is not applicable.

SYS: System common definition

UNT: Unit control information definition

SVR: Server common definition

FES: Front-end server definition

DS: Dictionary server definition

BES: Back-end server definition

1 Operand that can be added only; it cannot be deleted or modified.

2 If the specified value is too small, it may not be possible to restart HiRDB. When this is the case, restore the value to what it was before the change and then restart HiRDB.

3 If the specified value is too large, it may not be possible to restart HiRDB. When this is the case, restore the value to what it was before the change and then restart HiRDB.
