I don't know how you are calculating the
parse/execute ratio, but the reason I
pointed out that feature of ref cursors
was that it results in a higher level of
parse calls then you might expect.
Whether or not it's responsible for your
ratio is something I can't decide for you.
If your application is doing all it's data
calls through code like:
local_var := function_call(params);
array_fetch from local_var;
procedure_call_close(local_var);
Then every data fetch would result in a parse
call, so the number of parses per executes
would be high.
(As an aside - if this is the case, you could
improve the hit ratio by using single row fetches
instead of an array fetch ;) (Don't take that
remark seriously, I saw your earlier comment
about hit ratios not being a good target)

Jonathan,
could this be what is limiting hte parse/execute ratio? I know ratios aren't
the be all and end all, but I do not have access to that system.
Still its an intriguing question.
