Hi
Can somebody please explain in a lucid manner, what clustering_factor
means in dba_indexes? I have read that if the value is nearer to the
number of blocks occupied (or is it allocated?) by the table, it means
the data in the table is very well ordered and if the value is nearer
to the number of rows in the table then the data is scattered. Does it
mean that the clustering_factor is something like a pointer? A pointer
for each block if data is proper in the table and a pointer for each
row when data becomes scattered. If the table is going to grow at a
decent rate then won't the clustering_factor again go for a toss after
reorganization? Also should the reorganization of the table always be
based on the most used index for that table , for the exercise to be
effective? Finally, is it worth paying attention to this aspect?
Cheers,
Ashok
