PQ92501: CHANGE ACCUMULATION TOOL READS SOME LOGS UNNECESSARILY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If no activity exists in the log for a range indicated in
  syslogrange, GGC will reread that range until activity occurs
  that causes an image copy to be produced and a higher RBA to be
  recorded in syscopy. This change will cause mini log runs with
  no activity to be indicated in the GGC mini log control file.
  GGC will use these empty range indications in the mini log
  control file to avoid rereading unnecessary log ranges.
