[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

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

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.
regards

Hmm 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.

Two points:
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.

Hello John,
Thanks for the reply. I can't find any material so that I can aware with JSF introduction (with demos) and ADF Faces. So will you please suggest me some tutorial or demos related to JSF and ADF faces. I passed through the video demos of Oracle ADF homepage but still I can't understand the use of those tags.
regards,
Kush

Strangely, the same app i deployed on the Unix Development Server & the it works perfectly fine.
I went through all the forum solution, nothing has helped me out :(
Please Help.
Thanks.
Tina

Hi Timo.
Following are the answers.
Which jdev version? --- 11.1.1.3.0
Which kind of application? ---- It is a simple ADF fusion application.
What Other systems your application talks to? --- Application is having DB as Oracle & Weblogic server, doesnt talk to any other systems.
Which kind of security do you use? --- JAAS security.
I have a login page. After entering the UID & PWD, it gets verified against JAAS. If it is a valid user it displays the Screen with all the records for that User.
Problem is when i Click on the Login button, it tries to do something for a second & after a while it displays this exception on the screen.
My Local server is a Windows server, while this same application works fine when deployed to a Unix Server. I checked all the configuration on both the servers, didnt get anything that makes any difference.
Pls Help.
Thanks.
Tina.

Hi timo,
Thanks for ur reply...
we are using unbounded taskflow.
In Controller class(page def file), we refered the class that implements PagePhaseListener
The following override methods has created
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
//In this area we used to read the session object file which is written and sent by another application(application to application navigate).
If session object file exists,will allow the user to navigate into the requested page else will navigate in to login(security aspect).
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
Is we used Controller class wrongly ???
Is there any relationship with region controller???

Let me know if anyone got any clues?

User,
Apparently, you are an Oracle developer working on Fusion Apps. It seems to me it would be more appropriate to ask in an internal forum, seeing as that most of us here have no access to the software you're using.
