Howdy all. I am attempting to audit when people run ALTER TABLE statements and having a tough time. From reading docs and a book, it would appear that I would need to "alter system set audit_trail = db" before I can audit. However, when I try to run that I get "specified initialization paramter cannot be modified". I see this message when googling, but no clear resolution. I also see in a book that I should perhaps run "audit table" and then bounce the system. I do that, but then run "select * from dba_audit_trail" and it returns no records even though I've changed a table.
