APAR status

• Closed as program error.

Error description

• CUSTOMER REPORTING THAT BUFFER POOL HIT PERCENTAGE is 2177%.
  Here is the algorithm:
  ( (# of Sequential Getpages -  #Getpage Fails - # pages read
  from DASD) /
         # of Sequential Getpages - #Getpage Fails) * 100
  .
  Value should never be greater than 100
