Use the following formulas to calculate the memory required by in-memory data processing.
For HiRDB/Parallel Server, calculate the RDAREA used as in-memory separately for each server machine.
![]() ![]() ![]() ![]() ![]() ![]() |
![]() ![]() ![]() i=1
![]() ![]() ![]() ![]() ![]() ![]() i=1 |
n: Number of in-memory RDAREAs
A: Number of HiRDB files that constitute an in-memory RDAREAs
B: Total number of pages of in-memory RDAREAs
C: Page size of in-memory RDAREAs
D: Value of Formula 2
p: Page size in a Windows Large Page
Can be checked with the pdntenv command.
![]() ![]() ![]() |
The value found by Formula 2 is used to calculate the pd_max_resident_rdarea_shm_no operand.
