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

nothing happens with them, the continue doing there job as usual

redo and temp file don't get backed up

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

Nathan

what about it? the transaction gets rolled back

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

Nathan

of course (if we are talking rman here)

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
