APAR status

  • Closed as program error.

Error description

  • Real-time statistics on table with default value may result in
    -901
    
    The error can occur under the following conditions:
    
       - A table definition includes default values,
       - Real-time statistics (RTS) is enabled: AUTO_STMT_STATS = ON
       - RTS fabricates statistics for that table
    
    DB2 may corrupt the Column Descriptor within the PD (Packed
    Descriptor) by destroying
    the default value. This table is then unusable until 'runstats'
    is run on it.
    

Local fix

  • Do a manual runstats on the affected table.
