Fine tuning Oracle database using EM DB control

What are the good features with we should use to fine tune the db system using em db control.

All the diagnostics pack and the tuning pack capabilities are designed specifically to do what you ask.. As made available using the AWR and ADDM and used through the 'Advisor Central' link on the EM console.
You use them the way demonstrated in the online tutorials: http://www.oracle.com/technology/products/oem/index.html and look through the documentation indicated, especially under the links "Demos and Tutorials"

Jawahar,
Before you run this sql statement analyse those tables which you use in that query using dbms_utility.analyse_schema() then create one Mview for that query. Before you do all this use "Explain Plan for" this query and observe the statistics. See you need to create a table for Explain Plan. You can find that script in ORACLE_HOME/rdbms/admin/utlxplan.sql

Tuning Oracle Database - SGA Memory

Good morning Gurus,
I have this environment in my company:
SAP ECC 6
Oracle 10g
Aix 6.1
Our hardware resources:
Memory: 16GB Ram
Processor: 4 x 3.2Ghz
IBM Blade JS12
Recently, we migrated SAP 4.6C (Solaris) to SAP ECC (Aix). In this new version, a lot of users feel that the performance had decreased.
I checked SGA Memory in Oracle, and i noticed that this configuration didn't used all hardware resources.
This parameters was like these:
sga_max_size=712M
pga_aggregate_target=292M
db_cache_size=292M
processes=80
sessions=96
I changed for:
pga_aggregate_target = 4096M
sga_max_size = 4096M
sga_target = 4096M
db_cache_size = 600M
   I noticed, after this change the performance was perfect. We reduced the time db execution in 60%, but now it isn't occur.
   We changed this parameters on July 4nd, now the performance decrease in 30%.
   My question is, after this change, do we need to adjust the parameters in profile?
Thanks very much

> Note 617416 is pretty old (2006), you should follow note 830576 for 10g and there is no sga_max_size mentioned.
Yes it is old, because there are no significant changes on automatic memory management between 9i and 10g (11g is another history), so it is "valid"
sga_max_size is not mentioned in note 830576 because the memory parameters depend on the available memory. look at the recommendations for the other "memory" parameters:
DB_CACHE_SIZE                    Size depends on the available memory (Notes 789011, 617416)
LOG_BUFFER                       1048576
PGA_AGGREGATE_TARGET             OLTP: 20 % of available memory
                                 OLAP: 40 % of available memory
SHARED_POOL_SIZE                 400 MB or greater, refer to Note 690241
As you see, there is only one "hard coded" recommendation and one minimum recommendation.
It is not possible to give a recommendation for sga_max_size.
If you do not set it, Oracle automatically calculates it.
If it is set to small, Oracle will adjust it.
What it is important is to set up the DB_CACHE_SIZE and SHARED_POOL_SIZE, they will be the MINUMUM sizes if AMM is
used

Fine tuning the database query

To analyse the load of a particular object. we do use 'performance analysis' in ABAP. But let us suppose we've come to know that more load is on the database. i.e. suppose 80% on database, 20% on Application server. what could be the possible steps that u wud perform on the query so that the load gets decreased. we don't have a chance to transform the load from database to application server (such as using internal tables and hence reducing the load). we should do something on the database side. so what can we do. any solution would be highly appreciated.
thanks in advance for the solution.

Hi,
You should use ST05 and then Switch TRACE ON for SQL.
Then do your query again.
After you have run your query, you switch the trace OFF and then you display the trace.
When displaying the trace you can see which SQL queries that have been made and how long time they have taken (left most column).
If the time is RED that indicates a bad query.
Anyway. Doubleclick on the query to find out how the query is made.
And analyse the table(s) that are used and whether or not an INDEX is used.
If no index is used you can ADD an index to the database table(s) in transaction SE10. Or directly in the database if you have that possibilty.
ST05,
Trace on,
Run query,
Trace off,
Display trace,
Analyze trace.
Good luck!

Oracle Database 11i and

Dear friends,
Dou you know if "Oracle Business Intelligence Enterprise Edition Plus 10g works fine with Oracle Database 11i ???? i mean is compatible with thos version of database ???
Thanks a lot !!!!

Hi
The 10.1.3.3 version of OBIEE has support for 11g. I haven't tried using 10.1.3.2.1 with 11g, but I could imagine that 10gR2 connection pool might work instead.

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.

We are preparing for 1Z0-117: Oracle Database 11g Release 2: SQL Tuning, There is shortage of material available on net.There are actually a fair number of articles about the material covered on 117 on the net, but yes, the test is new enough that cheaters have not had much of a chance to email around illegal material such as dumps yet.
Can anybody please provide books or Dumps and share more idea about the exan.There is a significant amount of legitimate material you can use to study for the exam here:
http://www.oraclecertificationprep.com/apex/f?p=OCPSG:EXAM_DETAILS:0::NO::P2_EXAM:1Z0-117
As for ideas about the exam -- it's probably the hardest Oracle certification exam I have ever taken:

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?

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.
