The values of some of the single 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.

: Specification value cannot be modified because the operand is not applicable.

SYS: System common definition

UNT: Unit control information definition

SVR: Server common definition

SDS: Single 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 is 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 is was before the change and then restart HiRDB.

⁴ The following values for the HiRDB system definition operands can be different for each client. To change a value for a client, specify the operand in the client environment definition. For details about the client environment definition, see the HiRDB Version 8 UAP Development Guide.

HiRDB system definition operands	Client environment definition operands
pd_watch_pc_client_time	PDSWATCHTIME
pd_cwaittime_wrn_pnt	PDCWAITTIMEWRNPNT
pd_uap_exerror_log_use	PDUAPEXERLOGUSE
