Hi List,

this is a totally theoretical question:
can anyone please point me to the difference between sqlplus /prelim and oradebug direct_access? Until Miladins blog [1] I thought they would be the same, but he showed they are not.

So what are they really?
(Just my guess: oradebug direct_access is really direct access to SGA, but what is /prelim???)

thank you for all your hints,
