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
