APAR status

  • Closed as program error.

Error description

  • In pureScale environments, a query using an ISCAN-FETCH plan
    with UR or CS isolation level might return too few rows while
    inplace (online) table reorganization is running against the
    table.  The problem only affects DB2 version 10.5 on FixPack 4
    to FixPack 8.
    

Local fix

  • Use the WAIT FOR OUTCOME option or a stronger isolation level on
    the affected SELECT statement.
