CLUSTERRATIO or normalized CLUSTERFACTOR (F4) will indicate
REORG is necessary
for indexes that are not in the same sequence as the base table.
When multiple
indexes are defined on a table, one or more indexes may be
flagged as needing
REORG. Specify the most important index for REORG sequencing.
Tables defined using the ORGANIZE BY clause and the
corresponding dimension
indexes have a '*' suffix to their names. The cardinality of a
dimension index
is equal to the Active blocks statistic of the table. | |
