Calculating the space required for affinity collection

A number of data spaces are tables used when collecting affinity information.

About this task

Use the average length for the calculation, 200 bytes plus another 100 bytes for temporary tables. Using the average length removes the requirement to break the calculation down to each table. Collect affinity data as follows:

  1. Estimate the number of programs that possibly have affinity commands using the IA scanner. Call this number NUM_AFF_PROG.
  2. Estimate the number of affinity commands per program using the IA scanner. Call this number AVG_AFF.
  3. Calculate for Affinity data space as follows:
    (300 * NUM_AFF_PROG * AVG_AFF) = NUM AFF_DS in bytes
