Error description

  • In DPF environments, when a runstats command is submitted from
    an application that is connected to a database partition on
    which the table does not reside, the statistics collection is
    processed by another database partition, one on which
    the table resides.  In this situation, runstats sampling might
    behave incorrectly when the INDEXSAMPLE option or the REPEATABLE
    option is used.  The problem symptoms are as follows:
    - if only INDEXSAMPLE is set, runstats will not execute with
    index sampling
    - if only REPEATABLE is set, runstats will not use the requested
    repeatable seed, and index sampling will occur when it was not
    requested
    - if both INDEXSAMPLE and REPEATABLE are set, runstats will use
    both options, but not with the intended index sampling rate nor
    the requested repeatable seed
    
    The statistics logs can be viewed to confirm if the requested
    options were executed.
    

Local fix

  • Submit the runstats command from a database partition on which
    the table resides.
