PI27297: KD2VGLKD ZGLOK INCORROUT TOTAL GLOBAL CONTENTION AND FALSE CONTENTION PERCENT *****%

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The CUA screen KD2VGLKD and the Classic screen ZGLOK will
  display the Total Global Contention and False Contention values
  as *****%
  
  This will occur when the summed numbers total greater than 2gig.
  Ths sign bit is taken into consideration when
  summing the XES requests and contentions but is not taken into
  consideration when computing the percentage.
  
  The XES Request values are cumulative since the DB2 subsystem
  was started which explains how the numbers can get so large
  
  Help screen does not adequately describe how the percentages are
  computed.
  
  False contention percent is computed as
  Suspends False Contentions divided by the sum of
  XES Lock Requests
  XES Change Requests
  XES Unlock Requests
  Suspends-IRLM Global Contention
  Suspends-XES Global Contention
  Suspends-False Contention
  
  Total Global Contention Percent is computed as
  Total Contentions divided by the sum of
  XES Lock Requests
  XES Change Requests
  XES Unlock Requests
  Suspends-IRLM Global Contention
  Suspends-XES Global Contention
  Suspends-False Contention
  
  Total Contentions is the sum of
  Suspends-IRLM Global Contention
  Suspends-XES Global Contention
  Suspends-False Contention

  PROBLEM SUMMARY:
  When the total number of suspensions and XES requests is very
  high, total global contention and false contention percentages
  can display as asterisks.
  
  PROBLEM CONCLUSION:
  Compute contention percentages so that they display correctly.
