APAR status

  • Closed as program error.

Error description

  • When using WHERE CURRENT OF CURSOR, the table space skipping
    logic may not properly track which log files are needed for a
    table space roll forward.  Some log records for a tablespace
    being rolled forward may not be processed.  This can lead to
    table space roll forward failure, or may lead to missing and/or
    incorrect data for the tablespace being rolled forward.
    

Local fix

  • Set the DB2_COLLECT_TS_REC_INFO registry variable to OFF to
    disable the log file table space skipping optimization
