When an Oracle Instance is started, the characteristics of the Instance are established by parameters specified within the initialization parameter file. SPFILEs provide the following advantages over PFILEs: A PFILE is a static, client-side text file that must be updated with a standard text editor like "notepad" or "vi". An SPFILE (Server Parameter File), on the other hand, is a persistent server-side binary file that can only be modified with the "ALTER SYSTEM SET" command.These initialization parameters are either stored in a PFILE or SPFILE. This file normally reside on the server, however, you need a local copy if you want to start Oracle from a remote machine. This means you no longer need a local copy of the pfile to start the database from a remote machine.Tagged: duplicate database, ORA-65500: could not modify DB_UNIQUE_NAME, resource exists, RMAN-03009, RMAN-03015, RMAN-11003.

Use the following syntax to set parameters that take multiple (a list of) values: RMAN (Oracle's Recovery Manager) will backup the SPFILE with the database control file if setting "CONFIGURE CONTROLFILE AUTOBACKUP" is ON (the default is OFF). Look at this example: Hi, I am running Oracle 10g and used the Oracle Enterprise Manager to alter my UTL_FILE_DIR parameter.
As the PFILE is text based, one can edit it in an editor like vi on UNIX or Notepad on Windows.
