Hi,

No logical structures can be considered in the hot backup.. Tablespace backup, if u mean it in hot backup its purely putting the tablespace in begin-backup mode and taking the backup of the corresponding datafiles.(User managed).


JUst if u wish to take a logical backup(tablespace and table level) i suggest u to go for exp/imp utility..

Thanks
