    Question Unanswered: who prefetch datafile data to buffer cache?

    The following article mentions prefetch in Oracle, but it doesn't say which process does the prefetch - could be the session server itself. Sounds there is no dedicated prefetcher process in Oracle.
    Oracle9iDatabase Daily Feature - Data Block Prefetching

    Anyone has more idea?

    Good judgement comes from experience. Experience comes from bad judgement.
