PH10518: VARIOUS ISSUES ENCOUNTERED WHEN IMPROPERLY POSITIONING INTO A LOG DATASET.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When attempting to position inside a log dataset for more
  efficient access, Db2 Log Analysis Tool was not properly
  considering which log dataset was being processed when
  calculating the relative RBA. This can result in an ALAA447E,
  ALAA440E, S0C7 during decompression, or data not being reported
  accurately. Each of these issues is due to missing a needed log
  record during the Detail Report processing.
  .
  This is most likely to occur during non Hi-Speed processing in a
  non DATASHARING environment when SYSLGRNX processing has
  eliminated the first log dataset in the list of log datasets
  that match the log ranges needed to be processed.
  

Local fix

• Turn off SYSLGRNX processing using Misc flags=X until the APAR
  can be applied.
