My 2 favorite queries

For finding out what happened with queries, here are my 2 favorite queries..

For searching the awr and previous executions
select * from table(dbms_xplan.display_awr('3cmh637q9msjs',null,null,'advanced +peeked_binds'));

For looking through the cursor cache
select * from table(dbms_xplan.display_cursor('3cmh637q9msjs',null,'advanced +peeked_binds'));


The output looks something like this...
