RE: Best Practices for Partitions ?

Vivek

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 ?
