Title: RE: Delete slowing..

Mark, how many indexes are on the table?    Are there any unindexed foreign keys?

    Hi list people :)

    We have a customer who has been running a particular delete statement
    against a table for a while now, which usually ran within minutes. All of a
    sudden this table has suddenly gone from a few minutes right up to 50! He
    wants to diagnose why..

    Where would you start?

    I have a few ideas of my own - like stale stats, small rollback segments
    etc. - but am after some of your advice also before I get back to him
    tomorrow morning.. Not sure on the Oracle version, OS, or even amount of
    rows he is deleting or size of the table (yet, I'll find this out tomorrow),
    but there has to be a pretty standard way of diagnosing this..

    All help appreciated.

    Mark
