Hi,

I try to rename files from a database
the database is in mount state
it is OK for all datafiles
but for tempfiles I got the error below:

alter database rename file '/prd/data/ora/P200/02/P200_temp01.dbf' to '/prd/data/ora/P200/02/P100_temp01.dbf'
*
ERROR at line 1:
ORA-01511: error in renaming log/data files ORA-01516: nonexistent log file, datafile, or tempfile "/prd/data/ora/P200/02/P200_temp01.dbf"

I am sure the files exist.
Bug or feature ?
Thanks for your lights
