    Rman backup & Recovery for a datawarehouse noarchivelog mode

    Hi,

    I need some help on RMAN backup & recovery strategy for a 300GB datawarehouse running Oracle 9i R2.

    Our datawarehouse cannot turn on archiving due to performance issues.
    We need a faster backup strategy, that is why I am exploring RMAN B&R.
    2 concerns our application team have raised regarding the new backup strategy:
    1) need less down time, faster backup
    2) ability to restore the database to the required date.

    My RMAN backup strategy is:
    - Sunday (cumulative incremental level 0)
    - Mon - Tue (cumulative incremental level 2)
    - Wed (cumulative incremental level 1)
    - Thur - Sat (cumulative incremental level 2)
    (currently, rman backup to disk and using Recovery Catalog)


    I have tested this strategy, and I have no problem recovering until the last good backup.

    However, I am not able to restore the database to a specified date(i.e. last good backup is Thur, and need to restore database to Tue).

    Anyone has any suggestions?
    How about recovery to the previous incarnation, will this work?

    Cheers
