See Client environment definition (setting environment variables) in the HiRDB Version 9 UAP Development Guide.

This subsection describes the port numbers that are used, depending on whether system common definition and unit control information definition operands are specified.

To lock the port number specified in an operand, see the Port number used column in the table, and specify the applicable operand in a combination that uses that port number. For example, in (a) HiRDB port numbers, to lock the port number specified in the pd_name_port operand for a HiRDB parallel server configuration, do not specify pdunit -p.

(a) HiRDB port numbers

HiRDB port numbers are specified in the pd_name_port operand and in the pdunit operand's -p option. This subsection describes the port numbers that are used when these operands are specified.

For a HiRDB single server configuration

pd_name_port	pdunit -p	Port number used
Specified	Specified	Port specified in pd_name_port
	Not specified
Not specified	Specified	20,000
	Not specified

The following table shows the port numbers that are used when the utility special unit is installed.

Location specified		Port number used
System common definition		At single server		At utility special unit
pd_name_port	pdunit -p	Unit that has a single server	Utility special unit	Unit that has a single server	Utility special unit
Specified	Specified	Port specified in pd_name_port	Port specified in pdunit -p	Port specified in pdunit -p	Port specified in pd_name_port
	Not specified	Port specified in pd_name_port
Not specified	Specified	20,000	Port specified in pdunit -p	Port specified in pdunit -p	20,000
	Not specified	20,000	20,000	20,000	20,000

For a HiRDB parallel server configuration

pd_name_port	pdunit -p	Port number used
Specified	Specified	Port specified in pdunit -p
	Not specified	Port specified in pd_name_port
Not specified	Specified	Port specified in pdunit -p
	Not specified	20,000

(b) Scheduler process port numbers

Specify scheduler process port numbers in the following operands.

• pd_service_port operand
• pd_scd_port operand
• -s option of the pdunit operand

This subsection describes the port numbers that are used, depending on whether these operands are specified.

Location specified				Port number used
System common definition			Unit control information definition
pd_service_port	pd_scd_port	pdunit -s	pd_service_port
Specified	Specified	Specified	Specified	Port specified in pdunit -s
			Not specified
		Not specified	Specified	Port specified in pd_scd_port
			Not specified
	Not specified	Specified	Specified	Port specified in pdunit -s
			Not specified
		Not specified	Specified	Port specified in pd_service_port of unit control information definition
			Not specified
Not specified	Specified	Specified	Specified	Port specified in pdunit -s
			Not specified
		Not specified	Specified	Port specified in pd_scd_port
			Not specified
	Not specified	Specified	Specified	Port specified in pdunit -s
			Not specified
		Not specified	Specified	Port specified in pd_service_port of unit control information definition
			Not specified	#

#

If the pd_registered_port operand is specified in the system common definition or the unit control information definition, a port number in the range specified in the pd_registered_port operand is used. If the pd_registered_port operand is not specified, a port number is allocated automatically by the OS.

(c) Port numbers of transaction server processes, message log server processes, and unit monitoring processes

Specify the port numbers of transaction server processes, message log server processes, and unit monitoring processes in the operands shown below.

• Transaction server processes
  pd_trn_port operand and -t option of pdunit operand
  
• Message log server processes
  pd_mlg_port operand and -m option of pdunit operand
  
• Unit monitoring processes
  pd_alv_port operand and -a option of pdunit operand
  

This section describes the port numbers that are used, depending on whether these operands are specified.

pd_trn_port, pd_mlg_port, or pd_alv_port	pdunit -t, -m or -a	Port number used
Specified	Specified	Port specified in pdunit -t, -m, or -a
	Not specified	Port specified in pd_trn_port, pd_mlg_port, or pd_alv_port
Not specified	Specified	Port specified in pdunit -t, -m, or -a
	Not specified	#

#

If the pd_registered_port operand is specified in the system common definition or unit control information definition, a port number in the range specified in the pd_registered_port operand is used. If the pd_registered_port operand is not specified, a port number is allocated automatically by the OS.

(d) Port numbers used by the HiRDB reserved port facility

Port numbers used by the HiRDB reserved port facility are specified in the pd_registered_port operand. This section describes the port numbers that are used, depending on whether these operands are specified.

Location specified		Port number used
System common definition	Unit control information definition
pd_registered_port	pd_registered_port
Specified	Specified	Port specified in the unit control information definition
	Not specified	Port specified in system common definition
Not specified	Specified	Port specified in the unit control information definition
	Not specified	--
