PK82055: AN INTERVAL TABLE (THREAD ELEMENTS) HELD IN STORAGE CAUSING CONSUMPTION OF EXTRA CPU CYCLES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• AN INTERVAL TABLE (ThREAD ELEMENTS) HELD IN STORAGE CAUSING
  CONSUMPTION OF EXTRA CPU CYCLES
  
  There is an internal table (Thread Elements) held in storage
  that is growing larger than it should and since that table will
  be iterated on a lot during processing it can cause consumption
  of extra CPU cycles.
  

Local fix

• Having smaller subintervals?

  * PROBLEM DESCRIPTION: Historical collector storage buildup    *
  *                      and processing overhead due to this.    *

  PROBLEM SUMMARY:
  A large amount of storage is allocated to maintaining
  thread-related statistics and accounting data on a large system.
  
  PROBLEM CONCLUSION:
  Add internal code to monitor and clean these data structures
  periodically.  The code will dynamically adjust the cleanup
  cycle depending on the amount of storage currently in use.
