    Oracle Event

    Hi,

    What does 'db_file_sequential_read' and 'db_file_scattered_read' mean?

    I am interested with practical approach rather than theory definition.
    Regards

    db file sequential read: Single block read commonly seen for index block access or table block access by a rowid

    db file scattered read: Typically used for full table scan. Multiple blocks are read into the DB block buffer that are scattered throughout the memory.
