As you say Ian partitioning is a obvious answer as I imagine the billing data will be quite easy to range partition using dates. However why go to 9i, 8i has many partitioning options and it may be an easier upgrade as well as a leap that management might find easier to agree to.

Unfortunately removing data when there is a lot of RI involved can be quite complex and needs good knowledge of the schema and data dependencies. This knowledge is not always available and sometimes the cost in terms of man-hours is not one that management is prepared to pay.

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
