Hello Everybody ~~

I would like to derive the backup/restore procedure before a datafile resizing. Cos the size of the whole DB is quite large (>2T).
Any ideas for only DB datafile recovery if the resizing got problem. i know that the "alter datafile .. resize.." is quite safe but really wanna have a backup plan.

I have think about several approach:

1. Cold backup --> too large and time consuming for recover

2. imp/exp --> too many objects --> time consuming

3. Tablespace point in time recovery --> too complicated

Any other ideas and suggestions >??>

Thanks so much for all of your help !!@
