16.9 Determining the size of the list RDAREA

Use the following formula to determine the size of the list RDAREA:

Formula
Size of list RDAREA (bytes)
={
a
[Figure]([Figure]Si[Figure] f[Figure] + [Figure]Si[Figure] g[Figure])
i=1
+ 6 x (a + 1) + [Figure](1,024 x n) [Figure] (25 x b) [Figure] + [Figure]20,480 [Figure] b[Figure] + c x e
} x b
a: Number of HiRDB files that constitute the list LOB RDAREA
b: Page length of the list RDAREA# (bytes)
c: Number of segments for the list RDAREA
e: Size of a segment for the list RDAREA#
f: [Figure] {b - 20} [Figure] { [Figure] e[Figure] 32 [Figure] x 8} + 56} [Figure]
g: [Figure] (125 x b) [Figure] (16 x f) [Figure] x f
n: Maximum number of lists that can be created in one list RDAREA#
Use the following formula to find the maximum number of list RDAREAs.
[Figure]Total number of lists retained in server [Figure] number of list RDAREAs placed in server[Figure]
Si: Number of HiRDB file segments that constitute the list RDAREA#
#: Use the create rdarea statement of the database initialization utility (pdinit) or database structure modification utility (pdmod), or the initialize rdarea statement of the database structure modification utility to specify the 500 smallest integer multiple values at or above the value found using the above formula.
