Error description

  • Backup performance statistics reported by db2pd -barstats and
    printed to db2diag.log at the end of the backup with
    sqluxLogDataStats. e.g:
    
    
    FUNCTION: DB2 UDB, database utilities, sqluxLogDataStats,
    probe:2049
    MESSAGE : Other Backup Statistics
    DATA #1 : String, 488 bytes
    
    Database bufferpool flushing time: 186.00 seconds
    Table space bufferpool flushing time 1: 0.00 seconds
    Table space bufferpool flushing time 2: Not Recorded
    Table space bufferpool flushing time 3: Not Recorded
    
    might be incorrect (too low).
    
    Numbers reported in this section measure the time spent in the
    initial phase of the backup, when dirty pages from bufferpools
    are being flushed.
    The number reported as "Table space bufferpool flushing time 1"
    might be incorrect if database is using more than one bufferpool
    as it will show the flush time for last bufferpool associated
    with tablespaces being backed up and the not cumulative time for
    all bufferpools that were flushed at the begining of the backup.
