Assuming this is a system datafile, you can do this to move it to /var:

SQL> shu abort;
ORACLE instance shut down.

$ mv /old-location/system.dbf /var/system.dbf

$sqlplus '/ as sysdba'

SQL> startup mount;
ORACLE instance started.

SQL> alter database rename
 2  file '/old-location/system.dbf'
 3  to '/var/system.dbf';

Database altered.

SQL> alter database open;

Database opened.

Verify the result.

SQL> select name from v$datafile;

NAME
------------------------
/var/system.dbf
