Hi,

Yes. Please use the following command.
CREATE SpFILE = 'filename' FROM PFILE ='pfilename';

When both SPFILE and init ORA files are there, Oracle always uses the SPFILE.

Thanks,
Ravi

Or you could simply issue CREATE spfile from pfile='<init.ora file including path>.  SPFILE will be created in the default location. Which I can't think of at the moment. It is in the data directory on RAC.
I think it's in $ORACLE_HOME/dbs/spfile<sid>.ora.

When you make changes to spfile, it is a good practice so create pfile from spfile so you have an ASCII file which you can read and start the databse from when you get into trouble.

Or if you want to know the SPFILE that oracle is using you can issue the following command,

SQL> show parameter spfile

Details about SPFILE anf PFILE can be found out from the following URL.

note, when creating an spfile from a pfile, the database needs to be closed.

shutdown immediate;
create spfile from pfile='....';
startup open;
