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