Could you tell me what those steps are or where to find them? I have
a db that I delete about 1 million records a day from in a batch job.
The only special thing I do is every few days I reindex the table
involved to reclame the space burned by the indexes not reclaiming
space on deletion of rows. What other good and useful things could I
do?

Thanks
