Performance tuning in 11g for said query

Hello,
I have the below query which needs to be tuned:

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

              "J"."UPA_INC_TYPE"='P')do you have an index on PS_UPA_EQ_DC_BAL.UPA_INC_TYPE column?
reducing the number of rows returned in this step would be critical to speed up the NL join

Regarding using text editor in 11g for writting query

how can i use text editor in oracle 11g for writting query as in oracle 9i in which we use 'ed' command.

However I assume you are using sqlplus
If this is the case define the _EDITOR variable to one of the following as appropriate ....
DEFINE _EDITOR=notepad
DEFINE _EDITOR=vi

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 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.

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?
Cheers,

Performance Tuning Certification for Application Developer

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

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

Can i use "Oracle Database 12c: Performance Management and Tuning " training for getting certification on "Oracle Database 11g: Performance Tuning 1Z0-054"

i have taken "Oracle Database 12c: Performance Management and Tuning new" training from oracle university. Now i would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054" exam. Is it possible ?

I essentially endorse and refer you to Matthews' and John's post above.
I would differ with slightly with Matthew because my guess is you would often be able to use like for like 12c training for an 11g certification ( I believe there are precedents). BEFORE ANYONE ASKS THE OTHER WAY DOESN'T HAPPEN.
.... but totally concur with Matthew you would ill advised to procede on that basis without one of:
- This being advertised as possible on the website : e.g. https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=654&get_params=p_id:169 ... option 2 show courses.
- Confirmation from Brandye
- Confirmation from an Oracle Certification Support Web Ticket ( http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP )
... The more common (and in my opinion usually better) way would be get your 11g DBA OCP ( or higher first) and then take the 1z0-054. I am almost certain they will accept your 12c course for the 11g DBA OCP.
If you are choosing the route of not being a 11g (or 12c ) DBA OCP first but are on option 2 and relying on the course for certification then the issue is more in the balance and you are even more strongly advised to get confirmation before proceding (remember if the rules need to be changed for you only then any profit out of the exam is lost).
In general my understanding is Oracle would prefer to encourage people to train on the latest version of product that is available for training and will prefer to avoid restrictions which would cause you to train at a lower version. ( This is simply my guess at Oracle University Policy ... personal opinion only).
Having said all I have said I'd encourage you to go with the advice of the earlier two posts.

Performance Tuning for BAM 11G

Hi All
Can anyone guide me for any documents or any tips realted to performance tuning for BAM 11G on on Linux

It would help to know if you have any specific issue. There are number of tweaks all they way from DB to Browser.
Few key things to follow:
1. Make sure you create index on DO. If there are too much old data in the DO and not useful then periodically delete it. Similar to relational database indexes, defining indexes in Oracle BAM creates and maintains an ordered list of data object elements for fast retrieval.
2. Ensure that IE setup to do automatic caching. This will help with reducing server round trips.
3. Tune DB performance. This would typically require DBA. Identify the SQL statements most likely to be causing the waits by looking at
the drilldown Top SQL Statements Ordered by Wait Time. Use SQL Analyze, EXPLAIN PLAN, or the tkprof utility to tune the queries that were identified.
Check the Dataobject tables involved in the query for missing indexes.
4. Use batching (this is on by default for most cases)
5. Fast network
6. Use profilers to look at machine load/cpu usage and distribute components on different boxes if needed.
7. Use better server AND client hardware. BAM dashboard are heavy users of ajax/javascript logic on the client

Beta Testing Continues for "Oracle Database 11g: Performance Tuning" Exam

!http://blogs.oracle.com/certification/2009-0204-1123.gif!
The beta period continues for the Oracle Database 11g: Performance Tuning certification exam (1Z1-054), which is a single exam requirement for Oracle 11g DBA OCPs to earn the Oracle Database 11g Performance Tuning Certified Expert (OCE) certification. Read more on the <a href="http://bit.ly/UGJh4">Oracle Certification Blog</a>.

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?
Cheers,

Which tool is used for Oracle 11g performance tuning?

Hi all
I used statspack for 9i's performance tuning.
But with 11g R2 now I want to know which way are you using to do performance tuning?
Statspack? OSW? RDA? ADDM? Or other ways?
Thank you.

I would start with Automatic Workload Repository (AWR) reports to identify the bottleneck

MOS Doc 748642.1 - What is AWR( Automatic workload repository ) and How to generate the AWR report?
HTH
SriniThanks for your answer.
To read the MOS documents I need a Oracle Customer ID , is that right ?
(Where to get that ID ? Our company bought Oracle 10g without any Customer IDs in it )
Best Wishes.
