Thanks John for the advices.
I had tried to resize datafile on a test instance before I posted the question.
It seemed to work fine to me because there was no error. But as a newbie, I was just too nervous to conclude it works Because I didn't know how to verify it thoroughly and have the confidence to say it works.
