25.5.1 Estimation of the HiRDB reserved port facility

Organization of this subsection
(1) Estimating from statistical information
(2) Estimation of the recommended value

(1) Estimating from statistical information

The number of communication port numbers that HiRDB will use can be estimated from statistical information. Using the statistical analysis utility's Statistical information related to system moving, you can calculate the number of HiRDB communication ports from the following statistical information (for details, see the manual HiRDB Version 8 Command Reference):

Formula
Number of HiRDB reserved ports in use + number of ports allocated automatically by the OS that are in use when there are excess HiRDB reserved ports + 100*

* Added as a reserve.

(2) Estimation of the recommended value

The recommended value is determined from the formula in 25.4.1 Estimating the number of ports that a unit will use. This is the target value. During operation, use the value from (1) Estimating from statistical information.
