Ian,
Partitioning is a great way to archive stuff as long as there are no logical dependencies on it from data that will stay active. You're then able to convert the partition to archive table or just drop it if business rules allow.
If you make sure that partitions are in separate tablespaces you also gain the ability to make the tablespace readonly or to use the transportable tablespace feature to move the data and plug it into an "archive" database.

Regards,
Mike Hately

Hi All,

I previously posted this question to the Lazydba List and got a couple of replies, but thought I would also send it to this list as well to see if I can just get a couple more (so excuses to those people that have already seen it)

I am currently discussing with a customer their requirements for archiving data as their system is 4 years old and billing data is piling up which obviously is affecting performance. I am pushing for an Oracle upgrade, they are currently on 7.3.4 and I am trying to get them to go to 9i. The main reason for this is so they can use partitioning.

My question to the List is to try and find out other people's experiences in archiving complex and integral data and whether most have gone the partitioning path or some other path (ie. Something like separate tables and data migration).

So I would appreciate anyones comments, the path they chose, database size etc.

With Thanks
Ian Biddell
