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)

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
Regard

[ADF-11.1.2] Proof of view performance tuning in oracle adf
Hello,
Take an example of : http://www.gebs.ro/blog/oracle/adf-view-object-performance-tuning-analysis/
It tells me perfectly how to tune VO to achieve performance, but how to see it working ?
For example: I Set Fetch size of 25, 'in Batch of' set to 1 or 26 I see following SQL Statement in Log
[1028] SELECT Company.COMPANY_ID, Company.CREATED_DATE, Company.CREATED_BY, Company.LAST_MODIFY_DATE, Company.LAST_MODIFY_BY, Company.NAME FROM COMPANY Companyas if it is fetching all the records from table at a time no matter what's the size of Batch. If I am seeing 50 records on UI at a time, then I would expect at least 2 SELECT statement fetching 26 records by each statement if I set Batch Size to 26... OR at least 50 SELECT statement for Batch size set to '1'.
Please tell me how to see view performance tuning working ? How one can say that setting batch size = '1' is bad for performance?Anandsagar,
why don't you just read up on http://download.oracle.com/docs/cd/E21764_01/core.1111/e10108/adf.htm#CIHHGADG
there are more factors influencing performance than just query. Btw, indexing your queries also helps to tune performance

Performance tuning of Oracle 9i Database
I want to know, what are the different parameters in the tuning of Oracle 9i database.
A few, i can list like
1) Re-building of indexes
2) Making the heavy transaction tables lighter
3) Checking if the indexes are firing
In a similar fashion, i needed what are the other parameters which can be a good indication of the health of the database. I hope, my question is clear.
Please, help in solving the doubt.
regardsHmm there is parameter coming up called _<your db name>_fast=true in some later future release.Its still not implemented yet but expected to be coming up soon due to excessive demand.
Your list's first element only is the show-stopper.Richard Foote has talked extensively about this.Its almost never that a index is requiriing a rebuild.There should be benchmarks to prove the benefit (if any ) of the operation.Please visit his blog http://richardfoote.wordpress.com to readmore about this.
2) Making the heavy transaction tables lighter
I didnt get this one.
3) Checking if the indexes are firing
You mean by chance that they are in use or not?If yes than again this may not be the indication of the success truly.It may be possible that they are in use but not the right thing for the query.BTW indexes being used or not is not the database health check.Its the query's health check.
There are no certain parameters which needs to be on a cerain value.Every parameter and its value can have variation depending upon the environment,workload and most importantly release of the databse.If you want to benchmark your db's health ,I shall suggest take a STatspack report before the problem and when you see a variation in it and compare.This will give you the lead to find the bottleneck in the db's performance.Instance tuning(changing parameters) is the last resort or near to last one.

Disk IO performance tuning of oracle 10g 64bit on rhel5 64bit
Hi Friends,
I am very new on oracle database tuning part.
I am facing some issues on the oracle disk io data transfer rate on rhel5.
Please help me. Details of issue is below.
I am using the iscsi san storage to install the database. My san storage is having more than 100Mbps transfer speed.
When oracle backup is running the data transfer rate is spikes upto 100Mbps, but when oracle normal transaction is happening it is not going more than 30Mbps.
My data base is an hybrid one and more read transaction is happening. Server is running with 4 cpus and 16GB of ram.
Here i am providing the iostat command output. Please have a look into this and help me to resolve.
[root@hostname ~]# iostat -x 1 5

1. I can not read what you posted because you did not read the FAQ (upper right) and put tags around the listing so it would retain its formatting.
2. Even if I could read them I wouldn't as they are not necessarily relevant. What I would want to see is what query you are issuing that you think should be maxing out your disk subsystem and giving you the performance you expect. Single block reads read single blocks. Post the DML and the corresponding explain plan report generated using DBMS_XPLAN.DISPLAY or AUTOTRACE. Also the result of this statement in SQL*Plus.show arraysize
Because this is precisely what is going to be brought back with each round trip between the client (SQL*Plus) and the server. -
Performance Tuning in Oracle 10g during Migration - Insert Statements
Some of the tables contain a huge data e.g. 7 million records to be migrated.
The table structure of Source Database is different from the Target Database (Where we are doing the migration).
So we have made a use of temporary tables to collect the data from different tables using joins and populate the main table using INSERT INTO tableA SELECT * FROM tableZ
Now the problem statement.
Some of the queries take infinite time and data doesnt get inserted into the main tables. I have seen the explain plan and didnt find anything unusual. The same query works fine when we use date time stamp and restrict the data.
What parameters do we have to take care ? Is there any configuration needed on Oracle Server side ? If yes which parameters?Lets start with the basics. First what is 10g? Is that 10.1.0.3 or 10.2.0.4 or something else?
Second 7 million records is a relatively small dataset.
No one can possibly help you with no DDL, no DML, no Explain Plan output generated with DBMS_XPLAN.
We can make wild guesses but that is like closing your eyes in a dark room and trying to find the light switch.
Please repost all relevant information so someone can help you. -
Performance improvement in Oracle 11g
Hi,
What are the best suggestion to handle when we implement performance tuning in oracle? Below are the scenario:
Scenario # 1 : App team is running some test cases from front end. and there was a performace degradation while running the SQL statements in the transaction. it means 39 round trip to the database.
Of the 39 SQL statements – 21 inserts, 16 selects, 3 update. and the AWR report says that there were few most expensive SQL statements(some insert queries).
Scenario # 2 : There was a small percentage (<1%) of “buffer busy wait” which could be elongating individual SQL statements by an average of 27ms – need to do tuning by reducing data and index contention
So what is the best option available in oracle performance tuning other than Explain plan, AWR report, ORacle partitioning and SQL trace for the above 2 scenarios?? also implemented Oracle huge page by increasing the memory.. Performance was slighly improved but no use again it went back to the same state.
IS there any other way I can use Index_ffs_scan and RICHS_SECRET_HINT or caching a table in a memory options to make SQL statements much faster?? any other new methods available in ORacle performance tuning?? suggestions please.. also Pl let me know if you want more details..
Thanks

Standards of Performance Tuning required
Hi,
Plz guide me where i would be able to get standards of performance tuning of Oracle DB. So that i can compare the statistics with that.
Regards,First of all, make sure you understand performance concepts (http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14211/toc.htm), then don't go on comparing statistics as this will not take you but to a dead end filled up with tons of numbers.
It is not possible to talk about a so wide topic here, but If your database is running slow it could be because of one of two reasons, there is an outstanding demand of resources, or there is a lack of resources. Whichever the cause, it produces a bottleneck. Find the bottleneck, troubleshoot it and use statistics to gather a snapshot before and after the procedure. -
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.
RIThe best sources of information on performance tuning are:
1. Jonathan Lewis: http://jonathanlewis.wordpress.com/all-postings/
2. Christian Antognini: http://www.antognini.ch/
3. Tanel Poder: http://blog.tanelpoder.com/

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. -
Oracle 11 G database performance tuning
How to indexing the oracle 11G database?
Thanks in advance.Your question is like if you ask "Tell me how to fix a car". As you know people spend years learning how to fix different problems with cars; the same applies to database performance tuning. There is no way to answer this question in one post. Please ask a more specific question in an apropriate (database related) forum.

Oracle Application Performance Tuning
Hello all,
Please forgive me if I am asking this in the wrong section.
I am a s/w engineer with 2 years of exp. I have been working as a performance tuning resource for Oracle EBS in my company. The work mostly involved SQL tuning and dealing with indexes etc. In this time I took up interest in DBA stuff and I completed my OCA in Oracle 10g. Now my comany is giving me an oppurtunity to move into an Application DBA team and I am totally confused about it.
Becoming an Apps DBA will mean that the effort I put into the certification in 10g will be of no use. There are other papers for Apps DBA certification. Should I stay put in performance tuning & wait for a Core DBA chance or shall I accept the Apps DBA oppurtunity.
Also, does my exp. in SQL performace tuning hold any value as such with out an exposure to DBA activities?
Kindly guide me in this regards as I am very confused at this juncture.
Regards,

Hello bigdelboy , Thank you for your reply.
Yes, By oracle Apps DBA I meant Oracle EBS.
Clearing 1Z0-046 is an option. However, my doubt is will clearing both the exams Admin I and Admin II be of any help without having practical expericnce? The EBS DBA work involves support and patching, cloning, and new node setup etc.
Also, is my performance tuning experience going to help me in any way in the journey forward as a DBA/ EBS DBA?
Thank you for your valuable time.
Regards,
Jithin SarathThe way I read it is this.
People notice you are capable of understanding and performance tuning SQL. And you must have some knowledge of Oracle EBS. And in fact you also have a DBA OCA.
So there is a 98% + chance you can be made into a good Oracle Apps DBA (and core DBA). If I was in their position I'd want you on my team too; this is the way we used to bring on DBA's in the old days before certification and it has a lot of merit still. Okay you can only do limited tasks at first ... but the number of taks you can do will increase dramatically over a number of months.
I would imagine the Oracle Apps DBA will be delighted to have someone on board who can performance tune SQL which sometimes can sometimes seem more like an art than a science. The patching etc can be taught in small doses. If they are a good team they wont try to give you everything at once, they'll get you to learn one procedure at a time.
And remember, if in doubt ask; and if you dont understand ask again. And be safe rather than sorry on actions that could be critial.
If your worried about liinux: Linux Recipes For Oracle Dbas (Apress) might be a good book to read but could be expensive in India
Likewise: (Oracle Applications Dba Field Guide) may suit and even (Rman Recipes For Oracle Database 11 G: A Problem-solution Approach) may have some value if you need to get up to speed quickly in those areas.
These are not perfect but they sometimes consolidate the information neatly; however only buy if you feel they are cheap enough. You may well buy them and feel disappointed (These all happen to be by Apress who seem to have produced a number of good books ... they've also published some rubbish as well)
And go over the 2-day dba examples as well and linux install examples n OTN as well ... they are free compared to the books I mentioned.
