Advantages of SPFILE over pFile in Oracle?

SPFILEs provide the following advantages over PFILEs:
  • An SPFILE can be backed-up with RMAN (RMAN cannot backup PFILEs)
  • Reduce human errors. The SPFILE is maintained by the server. Parameters are checked before changes are accepted.
  • Eliminate configuration problems (no need to have a local PFILE if you want to start Oracle from a remote machine)
  • Easy to find - stored in a central location
