    Slow Index Creation

    Hi all,
    I am doing the migration using exp & imp utility. However, I manual create the index & it took so long to create the index on 3 x 2GB tablespace. What should I do in order to improve the index creation performance?

    Please advice.

    Thanks

    Build lots of indexes at the same time, using the PARALLEL and NOLOGGING keywords, and setting a reasonably large sort_area_size.

    Don't use exp/imp to migrate.
