how to get oracle init file pl sql like the spfile

Question

Hi,

I need to know the location of the oracle init file because i need to do a backup procedure from the plsql terminal, i need to take it from oracle like the spfile.

select value 
INTO   inicialOracle 
from   v$parameter 
where  name = 'spfile';

RESULT
------
C:\ORACLEXE\APP\ORACLE\PRODUCT\11.2.0\SERVER\DBS\SPFILEXE.ORA`

Your pfile will be present in $ORACLE_HOME\database directory and you will get your SID attached to file as follows init<sid>.ora

The problem with just copying the init file is, if changes were made to the spfile and a new init file wasn't created, then these changes won't be reflected in the init file. So it would be better to create an init file before taking a backup.

You can create a pfile from spfile like, (Assuming that you have the necessary privileges)

create spfile from pfile; --this will create the file in $ORACLE_HOME\database directory.
create spfile from pfile='location' ;
