    How do you drop and re-create indexes which were created at the time primary key were created?

    Thumbs up


    Using different tablespaces (on different disks)
    for a table and its index
    produces better performance
    than storing the table and index
    in the same tablespace, due to
    reduced disk contention.



    select 'alter index '|| OWNER ||'.'|| INDEX_NAME ||'
    rebuild
    tablespace INDX01;'
    FROM dba_indexes
    where owner = '*owner*'
    AND tablespace_name = '*table_name';

    outpuut would be like:

    alter index V0108.SYS_C0016832
    rebuild
    tablespace INDEX02;
