IIR 2.8.0.7 performance tuning suggestions / documents for Oracle 11?

Would we have any hints or white papers that would support a customer in IIR matching server tuning for initial load performance,
beyond the Siebel specific
Performance Tuning Guidelines for Siebel CRM Application on Oracle Database (Doc ID 781927.1)
which does NOT generate any statistics on the Informatica Schema?
Customer is starting production data load into Siebel UCM of over 5 million customer records . Their current bottle neck seems to be IIR queries and high IIR host resources usage.
This would be for Siebel 8.1.1.4 [21225] on Oracle 11.1.0.6; I currently do not know if ACR 475 with its EBC access is used or not; I'd be looking for any performance tuning suggestions on the Informatica & database side - I have not found anything helpful in the informatica knowledgebase and in the 2.8.0.7 docs the only performance tuning suggestions seem to be on IDT loads.
Obviously performance can be influenced by the matching fields used, but this customer will be looking for performance tuning suggestions keeping the matching fields and thresholds they got approved from the business side.
Any documents we could share?

Hi Varad,
Well, Oracle Metalink actually got it fixed for me! Got to give them credit.
I ran the 1st bit of SQL they sent me and it fixed it so I think it was only cosmetic. I've enclosed all of their response in case others may find themselves in similar situation.
Thanks again for YOUR help too.

==========================================================
1. Do you see any invalid objects in the database?
2. Please update the SR with the output of running the commands below
1.Connect as SYS.
set serveroutput on (This will let you see if any check fails)
exec validate_apex; (If your version is 2.0 or above)
If all are fine, the registry should be changed to VALID for APEX and you should see the following
message:
PL/SQL procedure successfully completed.
Note : The procedure validate_apex should always complete successfully.
With serveroutput on, it should show why Application Express is listed as invalid.It should show output like:
FAILED CHECK FOR <<obect_name>>
Or
FAILED EXISTENCE CHECK FOR <<object_name>>

Performance Tuning - Suggestions

Hi,
I have an ABAP (Interactive List) Program times out in PRD very often. The ABAP run time is about 99%. The DB time is less than 1%. All the select statements has the table index in place. Actually it isprocessing all the Production Orders (Released but not Confirmed/Closed). Please let me know if you have any suggestion.
Appreciate Your Help.
Thanks,
Kannan.

Hi
1) Dont use nested select statements
2) If possible use for all entries in addition
3) In the where addition make sure you give all the primary key
4) Use Index for the selection criteria.
5) You can also use inner joins
6) You can try to put the data from the first select statement into an Itab and then in order to select the data from the second table use for all entries in.
7) Use the runtime analysis SE30 and SQL Trace (ST05) to identify the performance and also to identify where the load is heavy, so that you can change the code accordingly
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0db4c9-0e01-0010-b68f-9b1408d5f234
ABAP performance depends upon various factors and in devicded in three parts:
1. Database
2. ABAP
3. System
Run Any program using SE30 (performance analys) to improve performance refer to tips and trics section of SE30, Always remember that ABAP perfirmance is improved when there is least load on Database.
u can get an interactive grap in SE30 regarding this with a file.
also if u find runtime of parts of codes then use :
Switch on RTA Dynamically within ABAP Code
*To turn runtim analysis on within ABAP code insert the following code
SET RUN TIME ANALYZER ON.
*To turn runtim analysis off within ABAP code insert the following code
SET RUN TIME ANALYZER OFF.
Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
Try to avoid joins and use FOR ALL ENTRIES.
Try to restrict the joins to 1 level only ie only for tables
Avoid using Select *.
Avoid having multiple Selects from the same table in the same object.
Try to minimize the number of variables to save memory.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
Avoid creation of index as far as possible
Avoid operators like <>, > , < & like % in where clause conditions
Avoid select/select single statements in loops.
Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.
Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
Avoid using ORDER BY in selects
Avoid Nested Selects
Avoid Nested Loops of Internal Tables
Try to use FIELD SYMBOLS.
Try to avoid into Corresponding Fields of
Avoid using Select Distinct, Use DELETE ADJACENT

Performance Based Equipment Document for Projects

Dear All,
We are implementing Performance based equipment process in ETM module. We want to create PBE document for projects where we want to enter the WBS against each line item in PBE document.
Currently we are able to create the recipient with reference type WBS where we assign WBS element and the same we are assigning in the PBE document to populate the WBS in PBE document. Here the issue is, we have to create the recipient for each WBS element to create the PBE document as WBS element will get populated for the recipient. We are not able to enter the WBS element directly in the PBE document as it is in non editable mode in the screen.
Could any body suggest how to enter the WBS element directly in the PBE document without the reference of recipient as we have thousands of wbs elements and creating recipient for each wbs element is not feasible.
Thanks and regards,
Basavaraj

Hi,
There are multiple questions in your query.
1. You have to define a counter for finding the performance based maintenance
2. Measurement document needs to be updated regulary by putting the counter reading.
3. Call objects will happen based on Plan and scheduling Or deadline monitoring by considering the updated measurement reading.
4. Running Deadline monitoring is based on frequency of the calls needed. may be daily or weekly or monthly (Example: Every week maintenance (Week time interval calls) for an equipment needs atleast weeky once deadline monitoring)
Thanks
Siva

Plz suggest book for Oracle - SQL and Oracle PL/ SQL

Hello Experts,
Please suggest me the best book(s) for Oracle - SQL
As well,

i got the following book..
OCA Oracle Database 11g:
SQL Fundamentals I
Exam Guide (Exam 1Z0-051) by John Watson
Roopesh Ramklass.
please let me know other books of this series...Just downloading/purchasing the Books is not going to help you learn SQL. You will have to read and practice.
My take is:
1. Oracle Documentation -- Download from Here
2. Effective Oracle by Design by Tom Kyte (Might have to purchase it as its not available for free download).
Once you read these and practice simultaneously, you would be able to grasp much more than reading all the above 4-5 books mentioned.
Also, I would say, to read just one of the books at a time than to make a mess by reading all and understanding none.

Performance Tuning Data Load for ASO cube

Hi,
Anyone can help how to fine tune data load on ASO cube.
We have ASO cube which load around 110 million records from a total of 20 data files.
18 of the data files has 4 million records each and the last two has around 18 million records.
On average, to load 4 million records it took 130 seconds.
The data file has 157 data column representing period dimension.
With BSO cube, sorting the data file normally help. But with ASO, it does not seem to have
any impact. Any suggestion how to improve the data load performance for ASO cube?
Thanks,
Lian

Yes TimG it sure looks identical - except for the last BSO reference.
Well nevermind as long as those that count remember where the words come from.
To the Original Poster and to 960127 (come on create a profile already will you?):
The sort order WILL matter IF you are using a compression dimension. In this case the compression dimension acts just like a BSO Dense dimension. If you load part of it in one record then when the next record comes along it has to be added to the already existing part. The ASO "load buffer" is really a file named <dbname.dat> that is built in your temp tablespace.
The most recent x records that can fit in the ASO cache are still retained on the disk drive in the cache. So if the record is still there it will not have to be reread from the disk drive. So you could (instead of sorting) create an ASO cache as large as your final dat file. Then the record would already still be on the disk.
BUT WAIT BEFORE YOU GO RAISING YOUR ASO CACHE. All operating systems use memory mapped IO therefore even if it is not in the cache it will likely still be in on the disk in "Standby" memory (the dark blue memory as seen in Resource Monitor) this will continue until the system runs out of "Free" memory (light blue in resource monitor).
So in conclusion if your system still has Free memory there is no need (in a data load) to increase your ASO cache. And if you are out of Free memory then all you will do is slow down the other applications running on your system by increasing ASO Cache during a data load - so don't do it.
Finally, if you have enough memory so that the entire data file fits in StandBY + Free memory then don't bother to sort it first. But if you do not have enough then sort it.
Of course you have 20 data files so I hope that you do not have compression members spread out amongst these files!!!
Finally, you did not say if you were using parallel load threads. If you need to have 20 files read up on having parrallel load buffers and parallel load scripts. that will make it faster.
But if you do not really need 20 files and just broke them up to load parallel then create one single file and raise your DLTHREADSPREPARE and DLTHREADSWRITE settings. Heck these will help even if you do go parallel and really help if you don't but still keep 20 separate files.

looks like these two steps hurts the most (causing the NL join take forever - because of the 4,5M rows)

reducing the number of rows returned in this step would be critical to speed up the NL join

Suggest book for oracle 9i DBA fundamentals 1

Performance tuning in PL/SQL code

Hi,
I am working on already existing PL/SQL code which is written by someone else on validation and conversion of data from a temporary table to base table. It usually has 3.5 million rows. and the procedure takes arount 2.5 - 3 hrs to complete.
Can I enhance the PL/SQL code for better performance ? or, is this OK to take so long to process these many rows?
Thanks!
Yogini

Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.

Also this informative thread can give you more ideas:
HOW TO: Post a SQL statement tuning request - template posting
as well as doing a search on 10046 at AskTom, http://asktom.oracle.com will give you more examples.

I want to do 1Z0-054 11g Performance Tuning

I want to do 1Z0-054 11g Performance Tuning
for this first needed 1Z0-007 or 1Z0-047 or 1Z0-051, then 1Z0-052 & 1Z0-054
1) Which should be best in 1Z0-007 or 1Z0-047 or 1Z0-051
2) Recommended books... where will get course materials.
Thanks

HarshI always think it is useful to be precise about these things:
You can take the exam +1Z0-054 11g Performance Tuning+ whenever you like. Simply book it, turn up and take it.
In the event you pass you've passed the exam!!! If you don't it is an expensive re-take.
However .....
While you;ve passed the exam you would not be a 'Oracle Database 11g Performance Tuning Certified Expert ' until Oracle confirms to you that certification, and Oracle you have identified all the requriements wht Oracle have detailed here:-
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=287
This indicates one of two additional pre-requisites to the exam pass:-
: Either (1) : A prior DBA 11g Certification.
: Or (2): Verification of your attendance to the Oracle Univerisity Oracle Database 11g: Performance Tuning training course.
Above you have sort of indicated the 11g DBA OCP credential requirements (omitting the mandatory training requirement) ( http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=198)
The journey to 'Oracle Database 11g Performance Tuning Certified Expert ' is a long one, and i suggest most people should look at the basics first. Begin by becoming familiar with http://certification.oracle.com.
If you wish to continue I would consider focusing on 1z0-051 as a first exam or possilby attempting to find suitable workforce development programme training (assuming oracle univerisity is too expensive). Please be aware IMHO Oracle are not responsible for WDP institutes and I suspect some are very bad.

Performance tuning of Oracle 10 g

Dear Team ,
I am in need of tuning my Database against the performance .
I have visited lots of Web pages in Net for Performance tuning .
It shows some values for the Performance tuning , But I dont how to read the values
Wheather my database is good or it need to tuned again .
So kindly help me for good performance tuning in my Database (Oracle 10g)
Regards
Augustine

Hi Augustine;
I am in need of tuning my Database against the performance .
I have visited lots of Web pages in Net for Performance tuning .
It shows some values for the Performance tuning , But I dont how to read the values
Wheather my database is good or it need to tuned again .First step should be run ASH AWR report than check your CPU usage(also other parameter) from Oracle Enterprise Manager console.
Check top5 event and try to understand what is happining on ur database. Actualyy There is no specific answer for your question, just check report try to understand to what eat your source? when it happens?what is fruquence etc.. So just run report and observe it
Check below search
http://www.google.com.tr/search?q=Performance+tuning+of+Oracle+10&rls=com.microsoft:en-us&ie=UTF-8&oe=UTF-8&startIndex=&startPage=1&redir_esc=&ei=v0fxS8bTCtOrsAaYqfTbAg
There are many docs related performance.
Hope it helps

Hi,
Can you please advise if there is any Oracle Performance Tuning certification for an Application Developer and Oracle 9i to 10G migration certification? If yes, can you please let me know its Oracle examination number?
I have already passed 1Z0-007 and 1Z0-147 in Oct 2008.
Thanks in advance,
Sandeep Kumar

... if there is any Oracle Performance Tuning certification for an Application Developer ...There is no performance tuning related certification for application developers. There is one for the DBA track.
Also -- to answer your question in the other thread:
So to clear this certification do I need to re-appear all the 3 exams as they were given in 2008 or just 1Z0-146 is enough.Having passed 1Z0-007 and 1Z0-147, if you pass 1Z0-046, you will gain the certification: Oracle Advanced PL/SQL Developer Certified Professional

Dates for "Oracle Database 11g: Performance Tuning" exam

Hi!
Today Oracle posted info about the new Oracle Database 11g Performance Tuning exam needed for the new expert certification:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_exam_id=1Z0_054#2
It says that pre-registration for the beta exam starts today, however, it does not say when the beta phase starts and ends. Does anyone know?
Thanks,
Marcus

Hello Hussein
Yes true, I remember it for the OCE and Linux exams they rescheduled the end date several times. As far as I know it is related to the number of participants and the given feedback.
I've also participated to several other exams, and I must admit that it is a long and hard process to get through. When I got the feedback 10 weeks after the beta period closure, I had to review nearly all the topics to get the exams passed the second time. But this it is a cheap and good exam preparation.
What about you Hussein? Do you think that's trivial?

Performance Tuning / RAC

Hi,
does anybody know recommendable docs, study guides or books covering Performance Tuning or RAC for database 11g.
Thanks in advance.
Uli

Hi Dan,
thanks for your reply. I have downloaded these docs and will read them as soon as possible.
Additionally I'm interested in recommendable books covering performance tuning.
What do you think about "Troubleshooting Oracle Performance", Christian Antognini, Apress? Customer reviews are very positive. However, it is published in 2008. Is it up-to-date? Does anybody know the "Oracle Performance Survival Guide", Guy Harrison, Prentice Hall?
Which performance books are your favorites?
Best Regards
Uli

Hi Gagan,
Can i use 10g SQL tuning advisor with 9i databaseNo, but you can do the same thing manually, and often do a better job:
Tune SQL with optimizer parms:

Find missing indexes:
1 - Search for unnecessary large-table, full-table scans
2 - Compare consistent gets to rows returned
