Oracle 11g Performance tuning approach ?

Hello Experts,
Is it the right forum to follow oracle performance tuning discussions ? If not, let me know what will be the forum to pick up some thread on this subject.
I am looking for performance tuning approach for oracle 11g. I learned there are some new items in 11g in this regard. For persons, who did tuning in earlier versions of Oracle,
what will be the best way adopt to 11 g?
I reviewed the 11g performance tuning guide, but I am looking for some white papers/blogs with case studies and practical approaches. I hope that you have used them.
What are the other sources to pick up some discussions?
Do you mind, share your thoughts?
Thanks in advance.

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.

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 )

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.

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,

Oracle Database 11g: Performance Tuning exam 1Z0-054

Hi,
I want to take the certification Oracle Database 11g: Performance Tuning exam 1Z0-054 and want to write the exam.
To earn the OCE credentials, I know that we need to take training from Oracle University. I am not an OCP currently.
Can I write the exam now and later take the course to meet the certification requirements? I know it is not the right way, but I can not pay $3000 for the course as of now. I can write the exam through self study. I want to check if I can take the exam now and later take the course.
Is it mandatory to take the course before taking the exam?
Thanks,
naveen.

Thanks,
naveen.Indeed you can take the exam now, and subsequently earn the 11g PERFTUNE OCE credential when you either:
1) complete, submit and get verified the OU authorised 11g perftune course (possible but seems a little cart before horse).
or
2) Become 11g DBA OCP.

1z0-054: Oracle Database 11g Performance Tuning Expert

I am planning to give the exam 1z0-054 to get the certification, "Oracle Database 11g Performance Tuning Expert".
The Certification Path says that, if you are and "OCP DBA 11g" then you can directly take this paper, and there is no Instructor Led Training requirement. Therefore, I decide to prepare for it by my own. Can someone guide me about the study material and dumps?
Regards,
Ahmer Mansoor

Therefore, I decide to prepare for it by my own. Can someone guide me about the study material and dumps?First of all, the word 'dumps' has a specific meaning. It is shorthand for 'brain dumps' which are illegal and can cost you this certification and any others you have taken.
http://blogs.oracle.com/certification/entry/0477
Second -- there currently is no study guide or book specific to this certification available at this time. I write study guides and this one is actually next on my list once I complete the current book for *1Z0-117: Oracle Database 11g Release 2: SQL Tuning*. I won't have a guide for 1Z0-054 until some time in May most likely. That said, I have some links to legal study material on the companion website for my guide series relevant to topics for this exam. It also has links to the Oracle documentation that contains information you need. Once I start writing the book for this exam, the links will expand rapidly as I research the topics for it and the documentation links may expand as well.

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

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.

Newbie question about Oracle 11G performance

I have a situation where a newer better faster server running Oracle 11gR1 is running considerably slower than an older slower server running Oracle 10gR2.
Both of these servers have the same web applications and same dumpfiles loaded into them.
I personally installed the Oracle 11g on the new server, however, I didn't install the 10gR2 on the older server, some one else did...
I have checked what I think are the basics: the tables are not missing constraints, the automatic memory management is enabled.
I know this is a really broad question.
Newer server:
Quad-Core AMD Opteron Processor 2352 2.10 GHz (2 processors)
16 GB memory
Windows Server 2008, 64 bit
Raid 5
Older Server:
Intel Xeon 1.8 GHz (2 processors)
4 GB memory
Windows Server 2003, 32 bit
Raid 5

Hi Derik,
I know this is a really broad question. No, it happens all the time! Here is a similar issue:
http://blog.tuningknife.com/2008/09/26/oracle-11g-performance-issue/
+"In the end, nothing I tried could dissuade 11g from emitting the “PARSING IN CURSOR #d+” message for each insert statement. I filed a service request with Oracle Support on this issue and they ultimately referred the issue to development as a bug. Note that Support couldn’t reproduce the slowness I was seeing, but their trace files did reflect the parsing messages I observed."+
I would:
1 - Start by examining historical SQL execution plans (stats$sql_plan or dba_hist_sql_plan). Try to isolate the exact nature of the decreased performance.
Are different indexes being used? Are you geting more full-table scans?
2 - Migrate-in your old 10g CBO statistics
3 - Confirm that all init.ora parms are identical
4 - Drill into each SQL with a different execution plan . . .
Raid 5 Don't believe that crap that all RAID-5 is evil. . . .
http://www.dba-oracle.com/t_raid5_acceptable_oracle.htm
But at the same time, consider using the Oracle standard, RAID-10 . . .
Hope this helps . . .
