Take a look at Steve Adams' site here
http://www.ixora.com.au/tips/design/partitioning.htm
It gives some good advice when considering partitioning, which I infact read
through this morning.
Composite or Range? Well, what kind of data does this table hold, what are
you trying to achieve from a partitioned table? It more depends on the
nature of your DATA.
Steve's jist, is that if you have a table partition, you should also have an
index that refers to that table partition, as this will also help with
maintenance operations etc. If you have an index for the partitioned table
as a whole, and decided to reorg one partition, which could be old data,
then you would also have to reorg the entire index - which could result in
user problems. If you have a partition specific index, you could just reorg
each specific partition without affecting performance on the whole.
Correct me if I'm wrong Steve..
Regards
Mark

Qs. Are Composite Partitions Better than Range partitions as a General rule
?
OR is it dependent on Nature of Business/Application ?
Qs. For Tables which are partitioned , is it advisable to Partition their
Corresponding Indexes Also with the Same Respective Key Values List ?
