Problem conclusion

Temporary fix

Comments

• The following modifications can effect to improve the
  performance of change and reload functions for many areas by
  increasing the number of thread subtasks with OCACHE=YES.
  1. Reduce data space storage utilization when change or reload
     function with OCACHE=YES is run.
     The current change and reload functions with OCACHE=YES
     obtain data space storage with total size of IOVF part and
     SDEP part.
     Therefore, a large number of thread subtasks with OCACHE=YES
     cannot be run concurrently because of resource shortage.
     In this APAR, change and reload functions with OCACHE=YES
     are modified to obtain data space storage with total size
     of used CIs in IOVF part.
     In addition, change and reload functions are modified not
     to obtain data space storage for SDEP part when one of the
     following conditions is met:
       - Reload function handles the Unloaded Segment records
         data set created by Unload function with SDEP=NO
       - Change function with SDEP=NO
  2. Eliminate redundancy paging services.
  3. Eliminate redundancy initialization of the internal buffer.
  
  Because the CI allocation algorithm for IOVF part is changed,
  the distribution of used CIs in IOVF part can different
  between before and after applying this APAR.
