17.9 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[Figure](a + 1) + [Figure](1024[Figure]n) [Figure](25[Figure]b) [Figure] + [Figure]20480[Figure]b[Figure] + c[Figure]e
}[Figure]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][Figure] 8} + 56} [Figure]
g: [Figure] (125 [Figure] b) [Figure] (16 [Figure] f) [Figure][Figure] f
n: Maximum number of lists that can be created in one list RDAREA*
Si: Number of HiRDB file segments that constitute the list RDAREA*
* This value is specified with the create rdarea statement of the database initialization utility (pdinit) or database structure modification utility (pdmod).
