For the same reason, I prefer init.ora over spfile. I can put comments for reason for specific parameter value, group similar parameters (e.g. all memory related parameter together etc). Putting comments also satisfy auditors.
Thanks

RE: changing init.ora and spfile
My only problem with creating pfile from spfile is I lose all of the internal documentation, why can't oracle keep all of those # lines in the spfile, dooohhh.

You can do that. What I usually do is create a pfile from spfile (don't overwrite your changes if you have already edited yours. Then I can keep a human readable copy around. So do your renaming or whatever, and put in place the new init<>.ora file.
Shutdown
Create spfile from pfile;
(sometimes I do the reverse also for same reasons as above, create pfile
from spfile).
Startup (it will use the spfile you just created). (Works as a test
also, redundant or not).

Subject: changing init.ora and spfile
Hello:
I want to make sure that I am making this change correctly. I have a 10.2.0.3 DB which users spfile and I need to increase the SGA_MAX and SGA_TARGET parameters. My plan is to
- modify the init.ora file
- make a copy of an existing spfile
- shut down the database
- restart as startup using pfile=initXXX.ora
- when database is started execute create spfile from pfile
That should guarantee that these changes are in the spfile and will not
be
lost next time the database is bounced. Am I correct?
thank you
