Hi Jonathan,
Code is wrapped and procedure name is provided by application team, since
these code runs every day ,Intention is to find the SQLID
related to that procedure

From what you're saying it seems you know that there is a procedure
(embedded in another procedure) that executes SQL and you want access to
the SQL text to test. Is there something stopping you from reading the
source of the procedure?

Hi Jonathan ,
Currently I was trying to figure out queries involved in
procedure.subprocedure .
So , actually one of the JOB(kind of Day end job ) of customer was
running slow , so my intention was to get sql's from the procedure for
evaluating their performance (just to rule out kind of plan change) , now
in this case procedure which was taking time was part of other procedure ,
so i tried to get details from ashrpti.sql but output was of same
procedure name (i.e sqlid/statement was showing the same name i.e
proc.subproc) which i was passing input for ashrpti , since it runs in
night time , it went unnoticed by application team and post completion of
job , team realize execution time is increased and hence , 10046 was out
from the option .
Hence was trying to figure out any option by which we can get sql's
details related to subprocedure

Krishna

David,
I think there was a time when the line numbers reported by hprof didn't
agree with the line numbers reported by user_source because of pl/sql
optimization moving lines around (constant folding, moving assigments out
of loops etc.) Have you come across that problem at all in recent versions.

The hierarchical profiler will link PL/SQL line number to Sqlid, and
profile time.
You can join it to ASH data to profile DB time, including profile by
line in the execution plan

Hi Stefan,
I am looking for live as well as post-problem analysis . I have never
used DBMS_HPROF , but I am exploring this. Thanks for letting me know
about
this !! , but using this, does it generate any additional load in a
highly concurrent system .
For post-problem any further way to take up .

Hello Krishna,
are you talking about live analysis or about post-problem analysis?
If you mean live, you can also use the PL/SQL hierarchical profiler
(DBMS_HPROF). It will show you exactly how much time is spent in your
PL/SQL code or with SQL execution.

procedure
Dear Gurus,
currently working on slowness issue of procedure which is part of
like : proc_name.subproc_name , over here i need to figure out thequery related to subproc_name and not by using 10046 trace .
I tried ashrpti.sql and used pls_object_entry but I didn't get anyvalues in the report .
Is there any way to figure out queries related to such subproc_namealso tried from dba_hist* views too by providing top_sql /pls_object
values but no luck .
procedure verified queries and by recommendation on it . but it was
Currently in my situation trace was taken (10046) and from
challenging to figure out queries without tracing.
It would be great help if you provide any light on it .
Regards,
Krishna
