Look into V$SQL and V$SQLAREA views.

1) You cannot for sure but if you have bought the option you can have a look at DBA_HIST_ACTIVE_SESS_HISTORY.

2) What do you mean by "server status"? I bet the status was "UP".

You didn't say what you mean by "server status".

Just to add some clarification to gazzag's above suggestion :

The v$sql would give the information only till a certain timeline until it exists in the shared_pool. As far as I have experienced, people usually look for first load time in v$sql. Therefore, I would go with Michel's suggestion.

v$sql does not give when the query was executed only when this occurrence of this statement in the SGA was first and last loaded.

Yes Michel, that was exactly my intention to clarify regarding v$sql as suggested above.

But your sentence "The v$sql would give the information only till a certain timeline until it exists in the shared_pool." is wrong regarding the question "How to know the when the query was executed?". The rest of your post is irrelevant to the question.

In addition, "loaded" does not mean "executed".

And about "Just to add some clarification to gazzag's above suggestion", I just think gazzag "thought" is answered the question and his answer is also wrong.
