Muchas veces se ha tratado de modificar los control files a través del famoso comando ALTER SYSTEM SET .... etc. Y este ha dado más de algún problema. Aquí les adjunto un método que hasta ahora no me ha fallado ni siquiera en la versión 11g de esta plataforma.
oracle@felipitux:~> sqlplus "/as sysdba"

- Se recrea el PFILE a partir del SPFILE
SQL> create pfile from spfile;
File created.
- Se baja la instancia
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit

- Se mueven de ubicación los control files a las particiones deseadas
oracle@felipitux:~> mv /u02/oradata/newton/control02.ctl /u03/oradata/newton/
oracle@felipitux:~> mv /u02/oradata/newton/control03.ctl /u04/oradata/newton/
- Luego se busca el PFILE creado y se edita con las ubicaciones nuevas
- Generalmente este archivo se ubica en $ORACLE_HOME/dbs/init
oracle@felipitux:~> cd /u01/app/oracle/product/11.1.0/db_1/dbs/
oracle@felipitux:/u01/app/oracle/product/11.1.0/db_1/dbs>vi initnewton.ora
- Luego de Editar levantamos la instancia en modo nomount indicando que vamos a utilizar un PFILE
oracle@felipitux:~> sqlplus "/as sysdba"

- Luego recreamos el SPFILE a partir del PFILE modificado
SQL> create spfile from pfile;

SQL> alter database mount;
Database altered.
SQL> alter database open;

Muy util, lo he probado en 11.2.0.1 y ha salido perfecto.
