The following table shows the formulas for determining the file sizes required for the execution of the optimizing information collection utility (pdgetcst):

File type	Formula (bytes)
Parameter file that contains optimized information	162 + 405 a + 567 b + 162 + 324 b g
Output results file	Collecting optimizing information by retrieval (-c lvl1 specified): 202 + 131 e Collecting optimizing information by retrieval (-c lvl2 specified): 370 + 561 d + 196 d Registering optimizing information using the parameter file that contains optimized information: 370 + 235 c + 387 f + 196 g

a: Number of specified indexes

b: Number of specified columns

c: Number of indexes defined in table

d: Number of intervals (total of number of sectors for all indexes)

e: Number of tables

f: Number of columns in table

g: Number of sectors (total of number of sectors specified in all column definitions)
