    Hot Backup

    Could someone give me a nutshell description of what happens with undo/rollback, redo, and temp files during a database hot backup.

    Thanks,
    Nathan

    What about the undo? What if someone does a rollback during a hot backup?

    I am having a mental lapse or something. So undo, temp, and redo are written to during a hot backup?

    No RMAN.

    1) alter database begin backup;
    2) copy data files to another disk
    3) alter database end backup;
    4) alter system switch logfile;
    5) copy archived redo logs to another disk.
    6) backup control file

    This is our procedure in a nutshell. In this scenario what is happening?

    Thanks,
    Nathan
