I have started my Database with pfile and now want to create spfile. I am using create spfile='location' from pfile; When I see the audit parameters in pfile, it is AUDIT_TRAIL=DB, but in SPFILE it is showing as AUDIT_TRAIL=OS, set previously but changed now. same with few other parameters. I changed my init file, bounce DB with pfile and now creating spfile. This is 9i with Solaris. regards - chirag
