Error description

  • In DB2 V9.1, V9.5, and V9.7, the PERCENT_ROWS_SELECTED column in
    the
    SYSIBMADM.APPL_PERFORMANCE table may return values that are too
    large for the numeric datatype.
    

Local fix

  • A work around is to create your SQL to use the appl_performance
    view but do the aggregation per agentid on both rows_selected
    and rows_read for each node. Then do an 'IF' stmt in the SQL
    where if rows_read = 0 then percentage = 0 else (aggregate
    rows_select / aggregate rows_read) * 100 is the percentage.
