Subj: | | Deleting from a huge table |

I have a very huge table of 1.2 billion rows. I load every day about 30 million to this table. After the load need to delete about the
same number of rows. The delete involves very complex logic. The PI on the table is non unique. The delete is based on columns, and not
all of them are in the PI. Currently the delete takes about 3 hours. I would like to know if this is the best that we can do. Our production
node is a W2K server with 4cpus. Could any one suggest a better way of deleting?
Thanks
