23.4.1 Estimating the number of ports that a unit will use

The following shows the target number of ports that a HiRDB unit will use:

Organization of this subsection
(1) HiRDB/Single server
(2) HiRDB/Parallel Server

(1) HiRDB/Single server

Formula
pd_max_users x 4 + 1,000

(2) HiRDB/Parallel Server

With a multi-front-end server configuration, decide the values for f and F for each front-end server, which will become the total number of ports. Use the following formula to calculate the target number of port numbers for each front-end server.

Formula
{b x [k x [(b - 1) [Figure] 2 + B + 1] + 1]
+ f x (k x (b + B) + D + 2) + d x 2}
x value of pd_max_users + 1,000
b: Number of back-end servers inside the unit
B: Number of back-end servers outside the unit
f: Number of front-end servers inside the unit
Each front-end server counts as either 1 or 0:
If the front-end server is inside the unit: 1
If the front-end server is outside the unit: 0
d: Number of dictionary servers inside the unit
D: Number of dictionary servers outside the unit
