Hi,

I'm having doubt on Online Backup. I want to know how the modifications to the datafiles take place while its correspoding tablespace is in 'backup mode'. Let's say:

Alter tablespace users begin backup;

inserting 50000 records... that generates lot of redo with frequent commits inbetween. Where Oracle will makes a note of these changes?

I appreciate if anyone can explain me how oracle works on the tablespaces while they are in Backup mode.

Thanks in advance,

Regards

BS
