QUREY PERFORMANCE, PLEASE HELP

Hi, I have written a query which is you can see below. The query qpproximately takes 50- 60 SEC to run, which I believe is way too high. The total rows returned is 10,000 . Any idead/lead what to do to improve the query timings ? The number of rows in each table are as follows :
ACCOUNTS : 1,580
PERSONNEL : 1,616
DIVISION : 15
LABOR_COMMITTED : 23,000
FISCAL_SYSTEM_PERIODS : 20
FISCAL_YEARS : 20
INDEXES :
ACCOUNTS TABLE- 1. ACCOUNT_ID ( Primary Key), 2. IN_AC_COMBINED(ACCOUNT_ID , ACCOUNT_MANAGER)
LABOR_COMMITTED TABLE- 1.LABOR_COMMIT_ID ( Primary Key) 2. IN_LC_COMBINED(PERSONNEL_ID, ACCOUNT_ID)
PERSONNEL TABLE- 1. PERSONNEL_ID ( Primary key)
The Actual Query :
SELECT AC.ACCOUNT_NUMBER , AC.ACCOUNT_NAME , AC.ACCOUNT_END_DATE ,
P1.NAME , D.DIVISION_NUMBER , P.SURNAME_ISI || ' '|| P.FIRST_NAME Person_Name,
ISNULL(P.EMPLOYEE_ID,P.VISITOR_NUMBER) Employee_Number, CONVERT(DATETIME ,

ROUND(LC.LCS_EFFORT,2) LCS_Effort , 'ACTUAL' AS 'Labor Type' ,
(SELECT CODE_VALUE FROM CODES CD WHERE CODE_ID = P.STAFF_CATEGORY_CODE_ID) STAFF_CAT
FROM ACCOUNTS AC, PERSONNEL P1 ,DIVISIONS D, LABOR_COMMITED LC , PERSONNEL P , FISCAL_SYSTEM_PERIODS FSP , FISCAL_YEARS FY
WHERE P1.PERSONNEL_ID IN (SELECT DISTINCT CHILD.PERSONNEL_ID FROM PERSONNEL CHILD, PERSONNEL PARENT WHERE PARENT.PERSONNEL_ID IN (7167,7041)

Asma,
I tried your SQL on my tables T1 and T2. Indexes are on C1,C2,C3 and N1,N2,N3. The data in T1 and T2 are shown below with the explain plan (also called EP) listed. You really need to do an explain plan (free TOAD is easiest to do this in) and respond showing your EP results.
By simply changing the optimizer mode to RULE I was able to get it to use indexes on both T1 and T2.

Notice the FULL table scan of T1 which you don't want, and neither C1 index is getting used (I've explained why below).

Though the C2 index is getting used (your r.c2 = 'Y' part in the where clause) the main problem your having here is the JOIN column (C1 in both tables) is not getting used. So the join you have ...
where substr(r.c1,-2,2) = substr(d.c1,-2,2)
isn't using an index and you want it too. There are 2 solutions to correct this..
Solution #1
The first is to make a function-based index for data. Since your doing SUBSTR on C1 that C1 index does not contain that partial information so it will not use it. Below is the syntax to make a function based index for this partial data ...
CREATE INDEX I_NU_T1_C1_SUBSTR ON T1 (SUBSTR(C1,-2,2));
CREATE INDEX I_NU_T2_C1_SUBSTR ON T2 (SUBSTR(C1,-2,2));
or also this way if it's still not using the above indexes ...
CREATE INDEX I_NU_T1_C1_SUBSTR ON T1 (SUBSTR(C1,-2,2),C1);
CREATE INDEX I_NU_T2_C1_SUBSTR ON T2 (SUBSTR(C1,-2,2),C1);
Solution #2
The second solution is to make another column in both table and place this 2 digit information in it, and then index this new column. That way the join will look like ...
where r.c_new_column = d.c_new_column
and
r.c_new_column between '01' and '72'
also with this new column the BETWEEN clause at the end you will not need the substring as well. Also remember BETWEEN on character values is different than numbers.
Final Notes
I just tried creating the functional index and I can't get it to be used it for some reason (I might not have the right amount of data), but I really think that is your best option here. As long as it uses the functional index you won't have to change your code. You might want to try using INDEX() in the hint to get it to be used, but hopefully it will use it right away. Try all 4 types of optimizer modes (CHOOSE, RULE, ALL_ROWS, FIRST_ROWS) in your primary hints to see if it will use the new function-based index.
You really do need to get explain plan going. Even if you make these functional indexes you won't know if its going to be using them until you look at the EP results. You can do EP manually (the SQL of how to produce the results is in OTN, though I find free TOAD is by far the easiest) and you will still need to have run the utlxplan.sql script. Oracle I do think has some GUI tools, maybe in OEM, that have explain plan built in as well.
I hope this helps ya,
Tyler D.

Aggregates Question (Performance) Please Help

I have 2 Questions first one is
1. Its been mentioned in the Forum that we can anlyse in the workload Monitor (ST03N) i went through that and did not find any Data for anlysis rather its showing information for Load Analysis.
2. Its been mentioned that we also check in RSDDSTAT table contents i checked this table but could not find data (How this table is Populated)
When i checked in
InfoCube Manage Screen --> Performance --> Check Statistics (Refresh Aggregate Statistics)
What are these for?
Can we Analyse to create aggregates or not with out BW Statistics data and just checking ST03N and RSDDSTAT and RSDDAGGRDIR tables?Please Help Me
I am using BI 7.Points will be assigned (Thanks)

Hi,
For ST03N
From Document
BI Administration Cockpit and New BI Statistics Content in SAP NetWeaver 7.0
As of SAP NetWeaver 7.0 BI, transaction ST03 is based on the Technical Content InfoProviders (unlike prior releases). Therefore, using transaction ST03 for BI Monitoring requires the Technical Content to be activated and to be populated periodically with statistics data.
So, looks like you have to install the new statistics technical content.
From thread /message/3461465#3461465 [original link is broken]
Rajani Saralaya K
IN BI 7.0, ST03n is based on BI Statistics cubes, so unless you install these cubes and schedule the dataflow you cant see any result in there. Even the same thing is mentioned in the note 934848.
For information about RSDDSTAT,
see /message/3627627#3627627 [original link is broken]

Yes, this index can be unique:SELECT count(*)

GROUP BY pls_id, ID_G5ADR_RADR
HAVING count(*) > 1;
no rows selectedUnfortunately statistics are not up to date. I can't gather it, because DBA must fix some DB blocks first.

 where log_obk_typ = 'G5ADR' and log_pls_id = 635 and rownum <= 200
 and exists (select 1 from g5lkl where id_g5adr_radr = log_obk_id); -- added conditionthe statement runs in about 1 second. Without the condition it takes 22.4 seconds to complete. I think that's because in the latter case the querySELECT ID FROM G5LKL ... did not find any row.
Edited by: JackK on Aug 8, 2011 6:16 AM
I changed the index T_G5LKL_ADR_FK to:CREATE INDEX T_G5LKL_ADR_FK_ID ON ROG_TEMP_G5LKL (PLS_ID, ID_G5ADR_RADR, ID);and it runs fast enought - *200 rows in 1-2 seconds*. Now the plan shows only INDEX RANGE SCAN.

Urgent - Oracle Applications Performance - Please Help me!

Hi folks!
I´m having a lot of performance troubles in Oracle applications, and the dba and the network analyst can´t help me. I´m having this trouble since 2 weeks, and nobody can explain why. The system is too slow and if i try a simple select in database it takes a lot of time, i think (i think ok?) there are som database troubles...
I saw some docs

4. Performance and Scalability site : There are a couple of excellent presentations and white papers which will give you the right way to do performance tuning. http://www.oracle.com/appsnet/technology/performance/content.html
but i need something more specifical like

Tag Performance -- Please Help!!!

I am using jsp custom tags for internationalization. Syntax is <lib:message key=�key�>
On one screen, the tag is used many times with various keys in order to get all the text. However, it causes serious performance problem because it seems like a new instance of the tag handler is created for each key. (I can see that by calling hashCode() method)
For example:
<lib:message key=�key1�>
<lib:message key=�key2�>
on the same page have different hashCode, which means they are two different instances. I am using Jrun 3.1, and I did include the release() method in the tag as follows:
public void release(){
key = null;
super.release();
Is there any way to use the tag instance pooling for this case?
I will greatly appreciate your help.
Jack

you might want to change the server.xml if you are using tomcat.
The TagPoolManagaer pools the tag library after their first use
for further refrence use

Hope this helps

Lookup transformation - Performance Issue -Please help!

Hi,
I have a Source table with 5 million rows. I am pulling all the rows from the source table, then doing the lookup with 5 different tables one by one.
I use Full cache as the lookup table size is very less only. I used 'Ignore Failure' option in lookup table as I need to do the left join. That means, even if there is NO match, those records also should be passed to the bottom.
Now, the problem is it is taking a lot of time. To load 1,00,000 records, it is taking 1 hour. The how about 5 Million rows? 50 hours? Could you please help me to find out what is the mistake i am doing here?

Is the performance still very poor if you only add for example a row count transformation after your source?
How many rows are there in the lookup tables? Are you only selecting the columns you need? Is the data type of the selected columns very large?

Please help me how to improve the performance of this query further.

Hi All,
Please help me how to improve the performance of this query further.
Thanks.

Hi,
this is not your first SQL tuning request in this community -- you really should learn how to obtain performance diagnostics.
The information you posted is not nearly enough to even start troubleshooting the query -- you haven't specified elapsed time, I/O, or the actual number of rows the query returns.
The only piece of information we have is saying that your query executes within a second. If we believe this, then your query doesn't need tuning. If we don't, then we throw it away
and we're left with nothing.
Start by reading this blog post: Kyle Hailey &raquo; Power of DISPLAY_CURSOR
and applying this knowledge to your case.

Please help!!! Poor performance Neo2...can't figure out why!!

Hi people,
I have worked on this issue for days!! I cannot figure it out! Here is the problem:
I used to have a Soltek AND Asus A8V mobo (both via chipsets), and scored approx 12,890 in 3dmark03 and 5,100 in 3dmark05, respectively ON BOTH BOARDS!
I have swapped out these boards with the msi neo 2 (latest revison) w/ bios 1.4. I have the SAME other equipment as shown in my signature.
I only get approx 9,800 in 3dmark03 and 3,889 in 3dmark 05. Roughly a 2,000/1,000 point lower difference respectively.
I cannot for the life of me figure out why. I have thought about this for days and searched this and many other forums to no avail.
I have installed the latest nforce 6.14 driver and the forceware 67.02. I have tried other drivers as well, using driver cleaner between installs. Still no go.
Bios is set at optimized default. AGP fast writes disabled. AGP Aperature size 256. The 6800gt is oc'ed to 400/1100. No oc on mobo.
I also did a search and found a review of this board w/ a 3dmark03 bench using the same video card as mine that shows a mark of 15,500 @ resolution 640x480.
So I tried the same test @ resolution 640x480 and scored 2,000 less marks.
I just don't understand this. Can someone please help and try to shed some light on this for me. I am SO perplexed about this!!

Why are you not using the Soltek or Asus A8V anymore?
i have almost the same machine as you and i to am very disappointed with the performance of my setup.
I have also tried other drivers and installing differecnt OS's (win2k, winXPsp1, winXPsp2), which did not seem to help. although drivers did make my benchmarks vary depending on dirver and OS.
I was just about to buy either the soltek 939 pin board or the asus A8V, to see if i can solve my performane issues.
the only other board that looks really good is the gigabyte GA-K8NSNXP-939, but this board also has an nforce3 chipset and i am begining to think that the nforce3 chipset sux.
The only other explanation for the lack of performance or perceived lack of performance is that we are running 64bit CPUs under a 32bit environment and therefore using only half the power of these CPU's.

Can't use profiler (Performance Analyzer) in Sun Studio 12, please help!!

Hi,
I've mandriva 2008 (linux), and I've installed Sun Studio 12.
At the first start of Sun Studio a message appear:
Warning - could not install some modules:
     ATD Sun Studio Core - The module named com.sun.tools.swdev.toolscommon was needed and not found.
     dbx Debugger UI - The module named com.sun.tools.swdev.toolscommon was needed and not found.
     ATD Performance Analyzer Actions - The module named com.sun.forte.st.mpmt/1 was needed and not found.
     ATD Performance Analyzer Actions - The module named com.sun.tools.swdev.toolscommon was needed and not found.
All other modules works correctly, but unfortunately I need the profiler (performance analyzer) because I want to speed up my C++ code. What can I do???
Please help!
NOTE:
I've added to my .bash_profile this lines:
PATH=/opt/sun/sunstudio12/bin:$PATH
export PATH
PATH=/opt/sun/sunstudio12/man/:$PATH
export PATH
LD_LIBRARY_PATH=/opt/sun/sunstudio12/prod/lib
export LD_LIBRARY_PATH
but unfortunately this don't solve the problem....

If I type `uname -p` this message appear:
[mlx@localhost ~]$ `uname -p`
bash: Intel(R): command not foundIf I type: --userdir won't work as you can see:
sunstudio --userdir /home/mlx/.sunstudio/12.0-Linux-Intel$R$\ Pentium$R$\ M\ processor\ 1.73GHz/I get an 426 line error (but this is the correct location, as man of sunstudio say), while if I type for example:
sunstudio --userdir /home/mlx/error 426 disappears, but I get anyway the error on the module:
Warning - could not install some modules:
     ATD Performance Analyzer Actions - The module named com.sun.forte.st.mpmt/1 was needed and not found.
     ATD Performance Analyzer Actions - The module named com.sun.tools.swdev.toolscommon was needed and not found.
     dbx Debugger UI - The module named com.sun.tools.swdev.toolscommon was needed and not found.
     ATD Sun Studio Core - The module named com.sun.tools.swdev.toolscommon was needed and not found.On the other hand I've searched the "id" exe and it is in /bin:
[mlx@localhost ~]$ id
uid=500(mlx) gid=500(mlx) gruppi=500(mlx)so I've created a sym link:
cd /usr/bin
ln -s /bin/id ./idbut when I start Sun Studio 12 I get again the error on the module.
So I've tryed to reinstall everything (yes, also OS) but it (partially) solves only the problem installing with batch_installer. Infact now I can use batch_installer but at the end of installation it say:
[root@localhost tmp]# ./batch_installer --accept-sla
Installation failed: cleanup successful.Anyway SunStudio 12 still works, but the main problem about the module of performance analyzer is still here...
how can I solve this? Please help!

Slow performance after iOS 7.1 upgrade, please help.

My kids have iPad Airs. One of them has a serious slow down in performance after upgrading to iOS 7.1. The others work fine. It is so slow that it is unusable. When you type a single character, it takes several seconds to show up on the screen. I'm rebooted and did a reset in Settings. Any other ideas? Please help.

I called Apple Support (800-275-2273) and they also recommended a reset: "Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears".
It came to a screen with a USB cable and arrow to iTunes logo. I had to connect to my PC and lanuch iTunes. iTunes recognized the iPad in restore mode. My only option per Apple Support was to restore to factory defaults. It appears all data is lost.
The Apple Support person would not admit that this is a known issue with iOS 7.1 even though you can go online and see that may people have slow performance after upgrading to iOS 7.1.
