    Hello All

    I have a big problem with slow oracle jobs on our production db, about a month ago, daily updates to a table started slowing up. By this i mean that they used to run every morning and be updated by around 9.30, but now they dont finish completion till 2.00 - 3.00,

    The Loads have not increased in size?
    I query the V$Transaction, & check the User_jobs views, there is noting in the V$transaction, and the user_jobs shows up as having run w/o any difficulties,

    in the session menu there are circa 50 sessions, with mostly inactive or killed status? Is this slowing progress? If so how do i get rid of these completely?

    I am really confused, any ideas on what else i could check?

    Any help is as always greatly appreciatated..

    You have to see all select, insert or update in this program to database and see if anyone is very slowly. I had a similar problem because a table have not an index and when the table was very large one select was very slowly.

    Sounds like a basic tuning job. 80% of performance problems are with the poorly written queries. Trace the session and see what tkprof says...
