WKDS_SIZE_PCT keyword

Use the WKDS_SIZE_PCT keyword to specify a percentage value to adjust the allocation size of intermediate work data sets HFPSnnnn, HFPInnnn, and HFPZnnnn.

This keyword is valid only when FPA allocates these data sets dynamically.

HFPZnnnn data sets are required for the TUNE command. HFPSnnnn and HFPInnnn data sets are required under the following conditions:
  • ANALYZE, CHANGE, RELOAD, and REORG commands when PTRCHKLVL=FULL is specified
  • TUNE command when AREASCAN=YES is specified
  • UNLOAD command when PTRCHK=DETAIL is specified

If any of these conditions is met and if relevant DD statements are not found in the JCL, FPA estimates the allocation size for the required intermediate work data sets and allocates them dynamically. You can use the WKDS_SIZE_PCT keyword to adjust the estimated allocation size to avoid abend B37 (out of space) or oversized data sets.

WKDS_SIZE_PCT is an optional keyword for the following commands:

  • ANALYZE
  • CHANGE
  • RELOAD
  • REORG
  • TUNE
  • UNLOAD
