The following formula is used to determine the size of the master directory RDAREA.

Formula

Size of master directory RDAREA (bytes) = { (a + 2)800 51 + (b + 120) 6,000 51 + (c + 240) 6,000 51 + (d + 240) 64,000 51 + e 64,000 51 + f 50 51 + 2 + 6 n }#1 4,096#2

a: Total number of data dictionary RDAREAs + total number of user RDAREAs

When the inner replica facility is used, also calculate the total number of replica RDAREAs.

b: Total number of tables to be defined

c: Total number of indexes to be defined

d: Total number of view tables to be defined

e: Total number of data types and index types to be defined

f: Total number of original RDAREAs and replica RDAREAs

If the inner replica facility is not being used: 0

The information on the original RDAREAs is not deleted even if all replica RDAREAs are deleted (this information is not deleted until the original RDAREAs are deleted).

n: Number of HiRDB files that constitute the master directory RDAREA

#1: Indicates the total number of pages in the master directory RDAREA.

#2: Indicates the page length of the master directory RDAREA.
