backup oracle system files
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 !!@
