PI08810: VARIOUS ISSUES AFTER QUIESCING A SUBSYSTEM IN A DATA SHARING ENVIRONMENT WHILE RUNNING IN CONTINUOUS MODE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When running in continuous mode, the last processed LOGPOINTs of
  each of the subsystems is stored in a file so Log Analysis Tool
  can pick up where it last ended. If a subsystem is QUIESCED, the
  last processed LOGPOINT for that subsystem begins to age since
  no new log records are processed. This aging leads to various
  issues such as DB2 archive logs being unnecessarily recalled
  from HSM, an internal array becoming full and not allowing
  further processing, or in some very obscure cases duplicate data
  being processed.
  

Local fix

• Manually delete the old LOGPOINT in the continuous mode file
  with the assistance of product support.
