Home -> Community -> Mailing Lists -> Oracle-L -> RE: 10046 trace - weird library misses
I wonder if soft parsing applies to pl/sql blocks as it applies to just
plain sql?? do you see the sql inside the function parsed less times
compared to execute?

Raj,
It's not dynamic.
>From SQLPlus prompt it looks like
SQL> BEGIN :n := FNC_SP_GET_SUBID_BY_EXT_KEY (:v); END; 2 /
Thank you,

Are you using dynamic sql? execute immediate? That might explain ... because exec immediate does a hard parse ... and it is documented too.

Dear friends,
I traced one of our test cases and found something weird.
Did anybody else observe this?
Env:
server - 9.0.1.4, Solaris.
client - weblogic 7, uses original oracle thin 9.0.1 jdbc driver to connect.
In fact, I can reproduce all this from SQLPlus
Here is an excerpt from tkprof below - why every parse is a hard parse? Looks like the problem doesn't appear when 10046 is not set, and it appers ONLY on pl/sql blocks returning data to client, normal selects OK. Looks like bug again. Any workaround?
And what are these "Misses in library cache during execute"?
9.2.0.2 on Linux works fine, i.e. no misses once it has been parsed.
BEGIN :1 := FN_GET_STATUS_ID(:2,:3); END; call count cpu elapsed disk query current rows
Misses in library cache during parse: 40
Misses in library cache during execute: 40
Optimizer goal: CHOOSE
Parsing user id: 40
This select
select LOADED_VERSIONS, EXECUTIONS, LOADS,PARSE_CALLS, parsing_user_id
from v$sql
where sql_text like 'BEGIN :1 := FN_GET_STATUS_ID(:2,:3); END;';
gives out whole bunch of these record groups
LOADED_VERSIONS EXECUTIONS LOADS PARSE_CALLS PARSING_USER_ID
Thank you for you time
