Optimizer timed out information

  ID    Name         Type              Description
  2320  QQTOUT       CHAR(1)           Indicates if the query optimizer timed
                                       out and did not consider all available
                                       indexes.
                                                                              Y - Yes
                                       N - No
  2322  QVTOUTR      BIN(32)           Reason code why the index was not used.
                                       Possible values are:
                                       1 - System invalidated the index.
                                       2 - User requested the index be rebuilt.
                                       3 - Index is a temporary index and is
                                           not the table being queried.
                                       4 - Cost to use this index, as determined
                                           by query optimizer, was too high.
                                       5 - Key columns of index did not match
                                           columns specified for ordering or grouping.
                                       6 - Key columns of index did not match
                                           columns specified for join criteria.
                                       7 - Use of this index would not minimize
                                           I/O at run time, as user requested.
                                       8 - Index cannot be used for a secondary
                                           file of the join query.
                                       9 - Table queried contains record ID
                                           selection which forces a temporary
                                           index to be used for the join query.
                                       10 - User specified . ignore decimal data
                                            errors. on the query which disallows
                                            use of permanent indexes.
                                       11 - Index contains select or omit criteria
                                            which does not match selection criteria
                                            in the query.
                                       12 - Index contains select or omit criteria
                                            whose compatibility with the selection
                                            in the query could not be determined.
                                       13 - Index contains one or more keys which
                                            may be changed by the query during an
                                            insert or update.
                                       14 - Index is being deleted or created in an
                                            uncommited unit or work by another job.
                                       15 - The sequence table associated with the
                                            index did not match the sequence table
                                            associated with the query.
                                       16 - The sequence table associated with the
                                            index did not match the sequence table
                                            associated with the query.
                                       17 - Index scan - key positioning could not
                                            be used for this index because the
                                            left-most key of the index did not
                                            match any column used in the query
                                            selection.
                                       18 - Index scan - key positioning could not
                                            be used for this index because the
                                            NLSS table associated with the index
                                            did not match the NLSS table associated
                                            with the query.
  2324  QQIDXN       VARCHAR(1000)     List of the indexes the query optimizer
                                       did consider.
