hi,
i want to know the step of persformance tuning and sql tuning.

I'd suggest you to refer to documentation: [Oracle Database 2 Day + Performance Tuning Guide 10g Release 2 (10.2)|http://download.oracle.com/docs/cd/B19306_01/server.102/b28051/toc.htm]

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.

Performance tuning of Oracle 10 g

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)
Regards
Augustine

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 log for ORACLE 10g

Hi everyone can anybody tell me where i can get the reporting from the performance logs in oracle 10g>?
i need to generate reports for audit trail, no of hits in the portal , top ten url , and how often the user view a page or portlet?
i thank you all in advance .....look forward for replies....thank you

Thaks for the reply...
but i cant go to the link =( may i ask u abt this , i read this link http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/OTN_CONTENT/MAINPAGE/ARCHITECTURE/MONITOR_DIAGNOSTICS_ANALYTICS_PORTAL.HTM#1
STATING : Oracle9iAS Portal Release 2 (9.0.4) provides some new, additional metric information. This release also collects some (pre-defined) metrics in the Oracle Enterprise Manager Central Console and creates historical reports, which can be published via Oracle Management Portlets on Portal pages
How to do the publishing? is there any references that will guide me from how to use the metrics to published in the portal pages? i requires all these ....PLEASE HELP

[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: Bulk Insert Oracle 10g

Following Situation: We have a VISUAL BASIC 6 Application (I know ... VB6 ... ), an XML-File with data and an Oracle 10g database. The XML-File has to be imported in the database.
Up to now the Application (Via ADO) analyses the XML-File and creates INSERT and UPDATE Stmts and sends them to the DB. The Stmts will be handled within one Transaction and the application sends each INSERT, UPDATE separate to the database.
But this is a performance desaster... as expected ... :-) The import takes several hours ...
Now, my task is to increase the performance, but how .....
I tried several things, but without the real success, e.g. ...
I performed some tests with the SQl*Loader. The Insert is really fast, but I can't make an Update, so I had to delete the existing data first. But I can't proceed the two steps in one transaction, because of the SQL*Loader.
I tried to write a stored procedure which accepts an ADO.Recordset as input param and then creates the Insert and Update statements within the DB to reduce network traffic, but I didn't find a way to handle a ADO.Recordset as a input parameter for a stored procedure.
Has someone an idea how I can import the XML file in a fast way into the existing DB (and maybe make an Replace of existing records during the import ...) within one transaction without changing the structure of the DB ??? (Oracle packages?? interface in C++ integrated in VB6....) Is there an way to import the XML-File directly to the DB?
Thanks in advance for any idea :-))

I tried to write a stored procedure which accepts an ADO.Recordset as input param ...., but I didn't find a way to handle a ADO.Recordset as a input parameter
for a stored procedure.Use SYS_REFCURSOR as the parameter type. Bulk collect it into a PL/SQL collection. Use FORALL to soup up the INSERT and UPDATE statements.
Cheers, APC

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.

Need OES Performance tuning steps for 10g

Hi Guys,
I am looking for a performance tuning document for OES 10g?
can someone provide me that or can someone illustrate the steps please?

Hi Gopi,
Following are the different tools provided by SAP for performance analysis of an ABAP object
Run time analysis transaction SE30
This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
SQL Trace transaction ST05
The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
check these links:

Remove Diagnostics Pack, Database Tuning Pack :Oracle 10g

Hi All,
I want to remove Application Server Configuration Pack, Application Server Diagnostics Pack, Database Configuration Pack, Database Diagnostics Pack, Database Tuning Pack from 10g due to license restriction. How can I remove these packs from command line syntax in 10g as I don't have GUI access so unable to perform from OEM?
Regards

Thanks Srini,
According to link provided by you we can revoke license with emcli tool but it is not installed with current database (10.2.0.4.0).
Please advice is there any procedure available which can disable all these packs in 10g.

Perfomance Tuning in Oracle 10g

Is the basic logic for tuning in 10g same as the traditional approach for tuning sql statements, like structuring of sql statements, using bind variables instead of constants, having an ideal max of 4/5 joins in a given query, etc.? I would like to know which is the reference book available. Thanks in advance

10g has lot of feature to tune sql tunnings. it has got new feature SQL Tunning Advisor,
which can advice u
to create index, statistics analysis
error in sql statement, recomendations
Refer, the 10g new feature oracle press book.

JMS Adapter Tuning in Oracle 10G SOA suite - Fixing the Errors

Hi All,
We are getting an error in Production environment while a BPEL process producing (enqueue) a message to a JMS queue by using JMS adapter. (partener link)
The error is as follows.
Adapter Framework unable to create outbound JCA connection.
file:/sw/appnew/product/SOA/10.1.3/bpel/domains/default/tmp/.bpel_CurrenListJMSProducer_1.0_4ec528ec93a8a6ff0278fab9701dcc71.tmp/CurrenListJMSProducerV1.wsdl [ Produce_Message_ptt::Produce_Message(OutputParameters) ] - : The Adapter Framework was unable to establish an outbound JCA connection due to the following issue: oracle.j2ee.connector.proxy.ProxyInterceptException: javax.resource.ResourceException: RollbackException: Transaction has been marked for rollback: null [Caused by: RollbackException: Transaction has been marked for rollback: null]
Please note that we are not getting this error every time, few BPEL instances are getting this error, around 3 out of 10 instances.
We are using Orcacle 10G SOA suite.
The BPEL process will take the messages from Oracle Apps adapter and send to the JMS queue, where we are getting error.
I can see in the BPEL.xml the "retryInterval" property set to '60' for both partner links (Apps adapter and JMS adapter).
But not set any other values. So,these values may be default.
We need to fix this issue soon.
I am requesting you all the Experts and Gurus, please let me know what can be done to fix this issue.
Thanks a lot in advance,
John.

Hi All,.
Is there any work around for the above issue?
I tried all the below JMS tunings, but not no improvement.
            <property name="useJCAConnectionPool">true</property>
            <property name="maxSizeJCAConnectionPool">500</property>
            <property name="retryMaxCount">10</property>
            <property name="retryInterval">60</property>
Please let
me know if any other logs or any other information is required in order to analyse the issue.
Thanks,
John
