RE: Changing DB_CACHE_SIZE to DB_BLOCK_BUFFERS

What would be the best way to do this in a non-RAC env? All that I can figure is:

ALTER SYSTEM RESET db_cache_size SCOPE = memory SID = '<sid>'; /* Since SCOPE = spfile doesn't work in a non-RAC env as the sid value isn't

CREATE pfile FROM spfile;
/* to make sure any other changes get saved in the pfile, since that'll be

Then remember to delete line 'db_cache_size = ...' from the pfile before the next instance bounce, then startup the instance using the pfile.

CREATE spfile FROM pfile;
/* so that the spfile is now current with pfile changes. */
