spfile help needed

Martin, Alan (Contractor) (DLIS)

Replies:
The docs say that once an spfile is generated, all changes to the DB
parameters occur via "ALTER SYSTEM SET <param>=<value> [comment] [scope]
[sid]", and the pfile is out of the loop. Based on my observations, please
comment on the following:
1) Is it true that immediately after "create spfile from pfile", the spfile
is not actually used until the first bounce?

Using an spfile or the old pfile, trying to ALTER SYSTEM on AUDIT_FILE_DEST
yields:
ORA-02095: specified initialization parameter cannot be modified.

2) Does this mean you must first "create pfile from spfile", edit the pfile,
and then recreate the spfile?

3) Since AUDIT_FILE_DEST is not system modifiable, why doesn't "alter system
set AUDIT_FILE_DEST = '<my_dir>' scope=spfile" work? That would avoid having
to perform (2) above.

4) Has anyone had any luck using "ALTER SYSTEM RESET <param>"?
alter system reset timed_statistics

ERROR at line 1:
ORA-00905: missing keyword

Any insight would be appreciated.
