Hey Dennis:

I created a range partition table with the last high_value being maxvalue. The partition key is partner_id (an incremental sequence). Now pmax (the last partition) has become very big and gives "snapshot too old.." while exporting.

Ultimate Plan

I realize that the ultimate solution will be the split the partition pmax, into enough segments so that
the new pmax has no data. Then at this point I will drop the pmax partition. Therefore when new partners come I will add partitions accordingly.

Maybe

But I was thinking If I can make pmax into a hashed subpartition, it will also distribute the data reasonably.
I dont have to have the segments separated by the partner_id because the data are not evenly distributed to the partners. partner_id , count(*)

  2             11164546466

... and so on..

Thanks very much for your help.

Ishwar

Ishwar - What Oracle version. Just off the top of my head, I think that 8i only allows the subpartition to be hashed. What is your goal?

Hey,

Can anyone say if there is a way to breakup an existing partition into subpartitons. The partition contains data.

Thx
Ishwar.
