APAR status

  • Closed as new function.

Error description

  • LOAD jobs to column-organized tables are failing if DATA BUFFER
    option is specified with low values.  According to
    documentation, expected behavior is: "If the value specified is
    less than the algorithmic minimum, the minimum required resource
    is used, and no warning is returned."
    
    The message in the db2diag.log shows:

    writer, 0 tuple, 16 total. HISTOGRAM 19633 available, 18 minimum
    

Local fix

  • Remove the DATA BUFFER clause from the LOAD command, or specify
    a higher DATA BUFFER value.
