Tuning a sql using tkprof
The most important query in our application is:
SELECT
COUNT ( * )
FROM I_JOURNAL m
INNER JOIN
LIU_TYPES lt
ON (m.LIU_TYPE = lt.LIU_TYPE)
INNER JOIN
LAWFUL_I li
ON (m.LIID = li.LIID)
LEFT OUTER JOIN
PHONE_BOOK pb
ON ( m.NORM_CIN = pb.NORM_CIN
AND pb.DELETION_DATE IS NULL
AND pb.OPERATOR_ID = :"SYS_B_00")
WHERE LIU_PRIORITY >= :"SYS_B_01"
AND (li.ID IN
(:"SYS_B_02",
:"SYS_B_03",
:"SYS_B_04",
:"SYS_B_05",
:"SYS_B_06",
:"SYS_B_07",
:"SYS_B_08",
:"SYS_B_09",
:"SYS_B_59",
:"SYS_B_60",
:"SYS_B_61",
:"SYS_B_62"))
AND (li.END_VALID_DATE IS NULL
OR m.DISPLAY_DATE <= li.END_VALID_DATE)
AND li.OPERATOR_ID = :"SYS_B_63"It should be fast: response time less than 5 seconds.
But in some sites, the number of records of the tables is big:
- I_JOURNAL: 5000000 rows
- LAWFUL_I: 1000 rows
- phone_book: 78000 rows
The worst case we have is when the operator_id is related to a lot of rows in I_JOURNAL, for example 800000.
In that case the response time is 20 seconds.
I've traced the query and the output of tkprof is:

Tuning PL/SQL - tkprof shows much more work for RECURSIVE STATEMENTS
Hi,
Firstly I'm not sure if this should be in "Database - General" or "SQL and PL/SQL". Since it's more of a performance tuning question than specifically about the PL/SQL, I'm going to put it here in "Database - General". I hope that doesn't offend anyone.
I've just started looking at a reported performance problem in our app. One of the developers set me up a procedure that replicates the issue, I ran it while tracing the session and then fed the trace file to tkprof. The results at the bottom of my tkprof output file look like this:

47 user SQL statements in session.

935 SQL statements in session.
31 statements EXPLAINed in this session.I'm looking in particular at that relatively high activity for RECURSIVE STATEMENTS, because to me, the NON-RECURSIVE (ie the actual submitted statements that form our code) looks pretty harmless. This is my first experience of trying to tune some complex looking PL/SQL and I've no idea what could be considered more "normal", but from what I think I know, and google searches, the results look quite odd to me.
Is this high activity for RECURSIVE STATEMENTS a problem, and if so, what should I start looking at to reduce that activity?
Regards,
AdosIf you have a PLSQL block or stored procedure running SQL statements, the SQL statements, too, will appear as RECURSIVE STATEMENTS in the trace file and tkprof.
It is a misconception that RECURSIVE STATEMENTS are only SYS statements doing data dictionary lookups / updates.
For example, I ran this :
SQL> create or replace procedure test_procedure as
2 begin
3 insert into my_emp_table select * from my_emp_table;
4 dbms_output.put_line('Rows Inserted : ' || sql%rowcount);
5 insert into my_emp_table select * from my_emp_table where emplid=1;
6 dbms_output.put_line('Rows Inserted : ' || sql%rowcount);
7 end;

SQL> alter session set events '10046 trace name context forever, level 8';
Session altered.
SQL> execute test_procedure;

Note that neither of these are are actually SYS statements agaisnt the data dictionary !!
Edit :
IF you read the last few lines, it would become evident that some (in my case all) the RECURSIVE STATEMENTS are non-SYS statements, actually being my code, not Oracle's code.

Pl/sql using enterprise manager or toad
A basic question : When it comes to writing PL/SQL code, testing, debugging and performance tuning(the pl/sql code itself), which of the tools are better (The OEM or would it be toad). I am looking for advantages that either or both of them have. Any documentation or tip on this would be great...
Note: I am not looking forward in just monitoring and tuning the sql statements that the pl/sql code has(which I would, anyways), but wanted to explore a possibility if either of the above tools can tell me something at a pl/sql level... like... this pl/sql code performs well, whereas the other one doesn't... This is the idea I have...
ThanksThe best tool for writing PL/SQL is that gray stuff between your ears.
A s/w tool can not take poorly designed and written PL/SQL code and make it "better".
As for determining how well the code performs - that also need gray matter and using tools like DBMS_PROFILE, execution plans, SQL Trace/TKProf.
I write lot of code. In Linux Vi (aka vim). Using SQL*Plus. This code, as code, is no worse (or better) than code written in TOAD, SQL*Developer, or whatever else.
It is not about the tool. It is how about one uses that tool. It was Van Gogh that created master pieces. Not his paint and brushes. -
We have to inverstigate about a reporting solution where things are getting slow (may be material, database design, network matters).
I have red a lot in MSDN and some books about performance tuning on SQL Server 2008 R2 (or other) but frankly, I feel a little lost in all that stuff
I'am looking for practical steps in order to do the tuning. Someone had like a recipe for that : a success story...
My (brain storm) Methodology should follow these steps:
Resource bottlenecks: CPU, memory, and I/O bottlenecks
tempdb bottlenecks

Edsger W. DijkstraHello,
There is no clear defined step which can be categorized as step by step to performance tuning.Your first goal is to find out cause or drill down to factor causing slowness of SQL server it can be poorly written query ,missing indexes,outdated stats.RAM crunch
CPU crunch so on and so forth.
I generally refer to below doc for SQL server tuning
http://technet.microsoft.com/en-us/library/dd672789(v=sql.100).aspx
For SSIS tuning i refer below doc.
http://technet.microsoft.com/library/Cc966529#ECAA

When I face issue i generally look at wait stats ,wait stats give you idea about on what resource query was waiting.

This is my first time using tkprof. I generated a sql trace in USER_DUMP_DEST. Then, I tried to use tkprof to format it but it said:
SQL> tkprof
SP2-0042: unknown command "tkprof" - rest of line ignored.

So, what is missing?TKPROF is a Oracle utility/tool, So run it at O/s Prompt :

Format tracefiles using tkprof
Hi,
What is the syntax to format tracefiles using tkprof?
Thanks,
KavithaTo make a tracefile readable, you need TKProf. Use the following command on the server:
TKPROF tracefile exportfile [explain=username/password] [table= …] [print= ] [insert= ] [sys= ] [record=..] [sort= ]
Example:
tkprof ora_12345.trc output.txt explain=scott/tiger
The statements between brackets are optional. Their meaning is:
explain=username/password: show an executionplan.
table= schema.tabelnaam : use this table for explain plan
print=integer restrict the number of shown SQL-statements. -
SQL TRACE/TKPROF VS SQL ACCESS ADVISOR
Hi All,
Can anyone please tell me what's the exact difference between SQL TRACE/TKPROF and SQL ACCESS ADVISOR in Oracle 10g.(By showing some examples)
And also why should I go for SQL ACCESS ADVISOR ?? (Since I have used the former all these days) :)
Why can't I still use SQL TRACE/TKPROF.
Please if anyone can pour light on this. Thanks in Advance.

Report To Show SQL Used In A Report
I am creating a set of quality reports using the apex views.
I would like to create a report to check the sql used in classic reports, but can't seem to find the right view to use.
If it was a interactive report I would use the SQL_QUERY column in the APEX_APPLICATION_PAGE_IR view, but this does not seem to exist for classic reports
Help appreciated.

You can use the Data dictionary view APEX_APPLICATION_PAGE_REGIONS. There's a field called "REGION_SOURCE" - just filter for the appropriate region type.

Having a brief look through your list of recently answered questions, you don't seem to award helpful points, even when you've explicitly saying (paraphrasing) "Thanks for your help". Maybe it's a tipping thing - perhaps you subscribe to the doctrine of Mr. Pink but, hey if it helps you get your question answered and it literally costs you nothing but a few seconds of effort, why not throw us a bone by awarding a point now and then? -
Run a report in PL/SQL using utl_http.request
Hi
I need to run a report in PL/SQL using utl_http.request
How that can be done ??
Thank you!Okay, backtrack.
A web server can deliver all kinds of content. From static HTML pages, to XML files and videos and dynamic content. Including reports.
The communication language (protocol) used to talk to a web server is HTTP.
UTL_HTTP is an Oracle PL/SQL library that implements the client side of this communication. It allows the developer to write code that acts like a web browser and communicates with a web server.
Now what do you not understand and cannot use?
HTTP is not simple and easy. You need to understand the basics of this communication language in order to communicate successfully with the web server. Like knowing the difference between GET and PUT and POST commands, how the URL query string works and so on.
Once you know that, you can look at how the web server provides reports. How do you authenticate as a web browser with the web reporting system? What URLs do you use to access which reports? How do you pass name-values to the web server as report parameters? What HTTP response formats (MIME types) does the web report server provide? Which one do you plan to use and how do you parse that response into a meaning structured data format?
If you're thinking it is "easy", think again. Sure, someone here can provide sample code that for example grabs a CSV report file from a web server and (using a pipeline table function), turn that into rows and columns. But that will not teach you the fundamentals you need to know and not equip you with dealing with the problem with your own brains, hands and keyboard.
PS. In other words, learn to crawl and walk before trying to run. Get to grips with how HTTP works before diving into the deep end of web report integration. -
Error while calling .svc web service from pl/sql using utl_dbws
Hello Folks,
I am calling a .svc web service from pl/sql using utl_dbws and encountering the following error
javax.xml.rpc.soap.SOAPFaultException: The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
Can you help me find what am I doing wrong?
Thanks

Hello,
i have question regarding PL/SQL using DECODE when i use following qurey in SQL plus it is working fine but when i try to run in tode it only display value of g.
everything else is blank........
so can u plz assist me on that .....
thanks in advance!!!!!!!!!!
SELECT
b.g,b.s,
COUNT(DECODE(a.u,'R',a.rep)) AS R,
COUNT(DECODE(a.u,'u',a.rep)) AS U,
COUNT(DECODE(a.u,'C',a.rep))AS C,
COUNT(DECODE(a.u,'I',a.rep)) AS I,
COUNT(DECODE(a.u,NULL,a.rep)) AS B
FROM AREA a, data b
WHERE a.rep = '454637'
AND a.rep = b.emp
GROUP BY b.g,b.sVery strange.
Find out if there are alterations to your SQL*PLUS envirionment. Warren mentioned user/database wierdness; the ALTER SCHEMA and other commands can affect privilges and what objects you can see. Sometimes these commands are buried in LOGIN.SQL and GLOGIN.SQL files (for SQL*PLUS), and more hard to find they can call files buried on a network somewhere.
Try the query without the DECODE() and see what's in the table without trying to modify the values in both envirionments. -
How to send mail in PL/SQL using exchange server details.
Hi Experts,
Business user has provided us the exchange server details to send mails.How can I send mails thru PL/SQL using exchange server details.user595740 wrote:
Business user has provided us the exchange server details to send mails.How can I send mails thru PL/SQL using exchange server details.Basic answer - not easily.
Oracle supports the standard application protocol SMTP - it does not support a proprietary protocol like that used by Exchange that only works on the Windows operating system. It however provides you with the flexibility to code this yourself.
If you for example use Microsoft MAPI (Mail Application Programming Interface), you can integrate it with PL/SQL using the external procedure (extproc) feature of Oracle.
In a nutshell, extproc enables you to create PL/SQL wrappers for public DLL calls. I posted sample code that demonstrates this in {message:id=2271919}. The sample code is for calling a DLL interface on HP-UX, but the concept is identical on Windows. -

Permissions needed for Applying SQL Tuning Sets/SQL Plans 11g?
What permission are needed for a user to apply/activate sql tuning sets (sql plans) in 11g? The user can capture and move the the sql tuning sets from a 10g database to an 11g database but is getting "ORA-01031: insufficient privileges" when trying to activate/apply the sqlplans in 11g.
The user has:
ADMINISTER SQL MANAGEMENT OBJECT and ADMINISTER SQL TUNING SET and EXECUTE on SYS.DBMS_SPM
The user is an administrator for our Data Warehouse team but they do not have sysdba priviliges.
Do you also know of a good white paper that covers the step by step instructions and permissions needed for aquiring and applying/activating sqlplans?
If more information is needed in order to respond please advise.
