Thanks to all who replied...
I ve solved my problem yesterday but still... by shutdown database.My question was how to move datafiles which are created by default in $ORACLE_HOME/dbs directory and when they are in SYSTEM tablespace. On 24*7*356 database it is NOT POSSIBLE to move datafiles (in SYSTEM tbs) on ONLINE database because we can not put SYSTEM tablespace offline!!!!but it is possible for other tablespace!!! So what is the point of having ALTER DATABASE RENAME FILE command if we can not rename datafiles which are reside in the system tablespace??? Regards,

Hi list,
What is the point to use "alter database rename file" command to move datafile? as we will need to update controle file anyway. So why not do the following directly to move datafile:

alter database backup contrlfile to trace and modify the location of datafile.
startup nomount and run the script inorder to update the controlfile. It works fine...

So what is the point of "alter database rename file" command?

Thanks in advance.
Regards,
-Jalil
