How to create a tempfile in TEMP after a refresh

Question

Hi.
After doing a refresh and now applying Autoconfig, I see that there was no temp file in the tablespace TEMP.
So now I create a datafile there, and name is /tmp01.
A message appears "A file with the same name already exists. Do you want to reuse that file?"
I selcted YES.
However, said file does not show in OEM. It does show on the server itself, but I am confused as to why we cant see it represented on OEM.
I would like to resolve this before I try and re run Autoconfig.
Thanks
