Performance tuning in planning

Hi All,
How can we improve the performance in Planning
I only know Arrange the dimesnion dense and sparse
Except this what can we do
and what is work folw in planning ?
Please any help
Thanks Inadvance

I assume you are having issues with your forms.. mostly forms issues are with JVM bottleneck or poor design. See below
Optimize heap size for planning process
Increase RAM on Planning server (trail and error)
data forms design with recommended methods (things like not using sparse in Rows)
Essbase optimization (please do some research )
Add security for all dimensions in planning at the detail level as much as you can (you can use Import security...this will reduce the query head from form grid)
Use suppression options on form and utilize composite form techniques.
Hope that helps.

Planning Performance tuning

What steps do we need to follow for Performance tuning of Planning?

If you like to get more responses to your questions, I'd recommend you include more information such as version, type of problem you are having, what you've tried so far, etc. General questions like this can be found on the admin guides. Also don't forget to mark the answers as helpful/correct. Personally, I don't like replying to people with high unresolved questions record.
For this question, you can check the answers for your other question: How can we do database optimization

Capacity planning (performance tuning of WLP 8.1 SP6 application)

Hi Guys,
I have one question regarding the performance tuning of the weblogic portal application (or may be any J2EE application for that matter) :
I understand that there could be lot of performance bottleneck areas e.g
(a) network issues (not enough bandwidth),
(b) bottleneck because of the DBs,
(c) application design/coding
(d) JVM might not have been tuned as per the business requirement of the application
(e) lack of clustering
(f) hardware problems (CPUs, RAMs etc)
Inorder to do the capacity planning for such an enterprise applications, what would be the best starting point?
Is it a good idea to start and profile the application using some profiling tools like OptimizeIt or JProbe? and then analyze the profiling the data and conclusion can be drawn interms of what and where the major bottleneck is into the application and accordingly it can be worked upon.
Or if there is any better and elegant way doing capacity planning?
Thanks for your time.
Regards
Jameel

Hi
id say start with a load tool that simulates average/ peak behavior with varied inputs and exercise your site . then profile if necessary.
Also start with the critical/most used portions of your site.
Its difficult doing the above because unles your migrating noone really knows the expected usage of your site. And its hard for someone to specify acceptable response times.

Planning to start the performance tuning but....

Friends,
Database OS: RHEL AS 3.0
Database: Oracle Release 9.2.0.4.0
Number of Tables: 503
TableSpace size - 1.8GB out of 3GB
Max.Records in a Table - 1 Million and its increasing..
Our DB Optimizer mode is - CHOOSE (is it RBO?)
We are not using enterprise manager and not installed any tuning scripts like statspack etc....
Currently we are taking user managed backup without any problem so we are continuing the same from 2004 onwards.
Now we want want to tune our database.(We have never tuned our database)
We would like to change our optimizer from RBO to CBO.
Can anybody tell me the first step for the performance tuning?
Please dont suggest me oracle doc im already studying.....its taking time....
In the mean time......
Step 1: Can i Analyze the table or dbms_stat package?
We have not at all used the analyze or dbms_stat. So can i start with any of the above or do u have any other suggestions for the 1st step?
Thanks

our manager feels that if we tune our db the performance will be more than compared to the current one.you have a mystique manager then, ask him what kind of "feelings" does he have about my database ;) there is no place for feelings in this game, this is life cycle to be successful ; testing->reporting->analyzing->take nedded actions->re-testing->reporting->analyzing..
so while you are surely reading the documentation;
Oracle9i Database Performance Planning Release 2 (9.2)
http://download.oracle.com/docs/cd/B10501_01/server.920/a96532/toc.htm
Oracle9i Database Performance Tuning Guide and Reference Release 2 (9.2)
http://download.oracle.com/docs/cd/B10501_01/server.920/a96533/toc.htm
first thing you have to do is to setup an appropriate test environment with same os-oracle releases, parameters;
-- some of them to check
SELECT NAME, VALUE
FROM v$system_parameter a
WHERE a.NAME IN
       ('compatible', 'optimizer_features_enable',
        'optimizer_mode', 'pga_aggregate_target', 'workarea_size_policy',
        'db_file_multiblock_read_count', .. )and of course schema set and data amount. Then you run your application on load and take statspack snapshots and do the same after collecting statistics;
-- customize for your configuration, schema level object statistics
exec dbms_stats.gather_schema_stats( ownname =>'YOUR_SCHEMA', degree=>16, options=>'GATHER AUTO', estimate_percent=>dbms_stats.auto_sample_size, cascade=>TRUE, method_opt=>'FOR ALL COLUMNS SIZE AUTO', granularity=>'ALL');
-- check your system stats, with sys account
SELECT pname, pval1 FROM sys.aux_stats$ WHERE sname = 'SYSSTATS_MAIN';after you have the base report and the report after change compare the top 5 waits, the top queries which have dramatic logical I/O changes etc. At this point you go into session based tuning in order to understand why a specific query performs worser with CBO compared to RBO. You need to be able to create and read execution plans and i/o statistics at least. Here are some quick introductions;
http://www.bhatipoglu.com/entry/17/oracle-performance-analysis-tracing-and-performance-evaluation
http://psoug.org/reference/explain_plan.html
http://coskan.wordpress.com/2007/03/04/viewing-explain-plan/
and last words again goes to your manager; how does he "feel" about a 10gR2 migration? With Grid Control, AWR, ADDM and ASH performance tuning evolved a lot. Important note here, after 10g RBO is dead(unsupported).

Performance Tuning Query on Large Tables

Hi All,
I am new to the forums and have a very specic use case which requires performance tuning, but there are some limitations on what changes I am actualy able to make to the underlying data. Essentially I have two tables which contain what should be identical data, but for reasons of a less than optimal operational nature, the datasets are different in a number of ways.
Essentially I am querying call record detail data. Table 1 (refered to in my test code as TIME_TEST) is what I want to consider the master data, or the "ultimate truth" if you will. Table one contains the CALLED_NUMBER which is always in a consistent format. It also contains the CALLED_DATE_TIME and DURATION (in seconds).
Table 2 (TIME_TEST_COMPARE) is a reconciliation table taken from a different source but there is no consistent unique identifiers or PK-FK relations. This table contains a wide array of differing CALLED_NUMBER formats, hugely different to that in the master table. There is also scope that the time stamp may be out by up to 30 seconds, crazy I know, but that's just the way it is and I have no control over the source of this data. Finally the duration (in seconds) can be out by up to 5 seconds +/-.
I want to create a join returning all of the master data and matching the master table to the reconciliation table on CALLED_NUMBER / CALL_DATE_TIME / DURATION. I have written the query which works from a logi perspective but it performs very badly (master table = 200,000 records, rec table = 6,000,000+ records). I am able to add partitions (currently the tables are partitioned by month of CALL_DATE_TIME) and can also apply indexes. I cannot make any changes at this time to the ETL process loading the data into these tables.
I paste below the create table and insert scripts to recreate my scenario & the query that I am using. Any practical suggestions for query / table optimisation would be greatly appreciated.
Kind regards
Mike

Steps for performance Tuning....!!!!

Hi all,
I need your help in Performance tuning.
While we do tuning in Oracle, apart from Indexes, where clause and order by clause, what are the other points we need to check. I mean explain plan etc...
I am working as Informatica Developer, but i need to make an documents which points out what are the step we can check while doing performance tuning on SQL queries.
Thanks in advance for your help.

Performance tuning for new OFMW environment

Hello
We have just set up a new UAT environment entirely on all Oracle FMW latest products which includes:
1) OS -RHEL V5
2) WebCenter
3) SOA Suite
4) Database
5) IDM
6) HTTP Server
7) WebLogic Server
As as post infrastructure setup plan we need to to performance tuning as well. Shall we do only WLS performance tuning or we need to tune each and every product in order to get optimum results.
Any guide? resource to help?
Pls advice
Regards
Dev

When you install the product soa-suite (and probably webcenter too) a prerequisite check is performed
that gives information about packages and parameters that need to be adjusted on your operating system.
For products that run on WebLogic Server you probably have to tune the JVM, examples can be found here:
- http://middlewaremagic.com/weblogic/?p=6930 (discusses JRockit)
- http://middlewaremagic.com/weblogic/?p=7083 (focuses on Coherence, but the considerations can be applied to other environments as well)
Examples that set-up the SOA-Suite can be found here:
- http://middlewaremagic.com/weblogic/?p=6040 (discusses considerations when installing the SOA suite)
- http://middlewaremagic.com/weblogic/?p=6872 (discusses considerations when adding the web-tier to the SOA suite)
The enterprise deployment guides can help too:
- SOA Suite: http://download.oracle.com/docs/cd/E21764_01/core.1111/e12036/toc.htm
- WebCenter: http://download.oracle.com/docs/cd/E21764_01/core.1111/e12037/toc.htm
These also contain sections on integration with Oracle Identity Management and the Oracle HTTP Server

Performance Tuning Guide Needed.

I've seen numerous references to a "Performance Tuning Guide" Is there
any way this document could be posted on the weblogic customer
downloads.
We desperately need this information. Even with working with Support so
far the process has been trial and error. Try this, then try that. I've
burnt many days just playing around with the properties and so far no
luck.
I've read just about every post in the performance newsgroup. Some seem
to be the same types of problems we are currently facing. Great
response when there are about 50 users. Horrible around 65. Slowness
doesn't seem to be gradual. All of a sudden it starts to crawl. So far
I haven't seen any posts regarding solutions (weblogic.properties
settings) which I could try and use.
We are currently using weblogic 4.0.3 on AIX 4.3 with Oracle 8.i. No
native performance pack for that release. Will upgrading to 4.5.1
increase performance dramatically? Our application is very database
dependent. We use a the weblogic connection pool using Oracle's jdbc
thin driver. Note Oracle's OCI driver has numerous bugs related to CLOB
and BLOB retrieval which are used heavily in our database.
Thanks,
Don DeLuca

Hi Don,
I can't comment on the public posting of the Capacity Planning document.
However, I can say that there is no magic formula for optimizing your
WebLogic application. The biggest things to look at are the application
design and code (e.g., unnecessary synchronization code), DBMS configuration
and database design, JVM heap size (bigger is not always better), number of
execute threads (more is not always better), number of database connections
in the pool, whether or not you are using the performance pack, how much
other activity is happening on the server machine, etc. I can tell you that
trying to simulate a large number of clients from a single JVM client (using
lots of threads) will lead you to believe that the server is having problems
when it is really the client software/hardware that is often the limiting
factor. In many of our large benchmarks, we end up using significantly more
hardware for driving the clients than for running the server(s).
Sorry I don't have any better answers for you,
Robert

No one wants my Performance Tuning experience?

I worked as a DBA for 2 years in IT major where my work was confined to Performance Tuning & monitoring
and so I had no opportunity to get the experience of Backup & Recovery,RMAN and other Core DBA responsibilities.
I had to leave in July last year due to my some other career interest. Unfortunately that didn't get
fulfilled.
So from January 15th I have decided to resume my career as a DBA.
I went to a 3 interviews ,but every time my lack of experience in Backup & Recovery and other Core DBA responsibilities is not making my case stronger in the interviews.
I am losing confidence over my chances of getting a job. Most(Almost 95%) of the IT companies want minimum 3 years experience and that too with Backup & Recovery.
I have not yet done OCA (I passed only 1z0 042). So i am planning to give 1z0-007 so that i become OCA.
My questions to all?
1.*How much value OCA hold in the market* along with 2 years experience(In India i am based,more specifically Pune)
2. How should i get the practical experience of Backup & Recovery at home itself?+_
3. I dont have the financial power to go for TRAINING part of the OCP, so how should i make my resume look strong?
4. Doesn't any company want a DBA who hasn't had a experience in Backup & Recovery. Is Performance Tuning & Monitoring experience such a waste?
Cheers,
Kunwar

OK. India has produced a lot of DBA's over the past few years, so I suspect the supply/demand situation is not in your favour, especially with the global economic climate.
And because of career break employers will often have other candidates who look stronger. And they will have certifications.
So you've been looking a month and got 3 interviews .... that's actually not that bad.
My questions to all?
1.*How much value OCA hold in the market* along with 2 years experience(In India i am based,more specifically Pune)In general not a lot. However the only thing stopping you gettig an 10g DBA OCA is an SQL exam pass. Now if you can't pass that exam then you don't deserve the job. And given you've passed 1z0-042 an employer wll ask why who haven't passed the SQL exam (especially if you're into tuing and performance). People in India seem to love 1z0-007 .... I prefer to see people who have taken 1z0-051 or 1z0-047. However I suspect you cannot afford to spend the extra time on 1z0-047 as you need to concentrate on backup/recovery.
2. How should i get the practical experience of Backup & Recovery at home itself?+_Hopefully you've got kit to practice on.
3. I dont have the financial power to go for TRAINING part of the OCP, so how should i make my resume look strong?Resume's are not my best area. However in your case studying and passing 1z0-043 will help. 1z0-043 is 50% backup and recovery so that has synergy with your weak area. If finance is an issue consider a WDP course if you can get one. Some eligible courses are cheaper than others, but even they may be beyond reach,
4. Doesn't any company want a DBA who hasn't had a experience in Backup & Recovery. Is Performance Tuning & Monitoring experience such a waste?
Obviously performance tuning and monitoring is not a waste ..... but remember Oracle is increasingly attemting to automate these in later vesions, and different techniques are available in 11gR2 compared to 9i.

KunwarYou might find: RMAN Recipes for Oracle Database 11g : A Problem-Solution Approach ... ISBN13: 978-1-59059-851-1 ... a little useful.

Performance tuning through OEM

Hi,
I am unable to run performance tuning pack through OEM. Initially when i was not connected with any production database it worked. Now whenever i click performance manager, performance manager over view, etc it simply hangs where as diagnositc packs such as oracle expert are all working. I have increased the java_pool_size to 50M from 24M both in the remote database machine and in server but still i unable to run it through remote database machine. I have configured rman in the remote database and taking fullbackup, logical back up through it but the performance pack hangs whenever i run it. I am new to dba. statstical report collected through statspack report gives no idea for me to tune. Please help me what to do in this regard to tune the database.
What are the vital points one has to tune and how to tune it.

Brain heart,
As you have mentioned that you are new in Tuning so I shall say first is to understand what exactly we are hunting for.Please read Performance Tuning guide frm oracle docs.
You have not mentioned any version for your db so I am assumig 10g.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/toc.htm
Also there is an excellent guide from 9i docs, called Performance Planning also read that one.
And to understand tuning and its various know hows, get these books,
Optimize Oracle Performance--Carry Millsap
Oracle Wait Interface --Richmond Shee
Forecasting Oracle Performance --Craig Shallahamer
These will help you in understanding alot of things which will help for sure.

Performance Tuning for BAM 11G

Hi All
Can anyone guide me for any documents or any tips realted to performance tuning for BAM 11G on on Linux

It would help to know if you have any specific issue. There are number of tweaks all they way from DB to Browser.
Few key things to follow:
1. Make sure you create index on DO. If there are too much old data in the DO and not useful then periodically delete it. Similar to relational database indexes, defining indexes in Oracle BAM creates and maintains an ordered list of data object elements for fast retrieval.
2. Ensure that IE setup to do automatic caching. This will help with reducing server round trips.
3. Tune DB performance. This would typically require DBA. Identify the SQL statements most likely to be causing the waits by looking at
the drilldown Top SQL Statements Ordered by Wait Time. Use SQL Analyze, EXPLAIN PLAN, or the tkprof utility to tune the queries that were identified.
Check the Dataobject tables involved in the query for missing indexes.
4. Use batching (this is on by default for most cases)
5. Fast network
6. Use profilers to look at machine load/cpu usage and distribute components on different boxes if needed.
7. Use better server AND client hardware. BAM dashboard are heavy users of ajax/javascript logic on the client

Performance Tuning on PL/sql

Dear all,
I am not sure whether I am right to post this enquiry here, please correct me if I am wrong.
I have a sql stmt that run for a long time and caused a error of 'out of temp sapce' in oracle server. How can I tune my sql for better performance using command 'EXPLAIN PLAN'? How could I know the details information for those columns in the table 'PLAN_TABLE'?
Best Regards,
Marius

Read the "Database Performance Tuning Guide and Reference" for your version of Oracle (available online, right here).

I recommend :
1. use SQL tracing with DBMS_MONITOR and then TKPROF on raw SQL trace file
2. call the function as it used in your production environment
See good examples in http://www.oracle-base.com/articles/10g/SQLTrace10046TrcsessAndTkprof10g.php (just refer to DBMS_MONITOR examples and TKPROF).
Note that SQL trace will only trace SQL and not PL/SQL. If SQL elapsed time does not match function call elapsed time close enough, you need to use DBMS_PROFILER to know where PL/SQL non SQL code elapsed time is used.
I don't recommend using EXPLAIN PLAN because it has known limitations http://docs.oracle.com/cd/E11882_01/server.112/e16638/ex_plan.htm#PFGRF94673 (others have said "EXPLAIN PLAN lies" - you can google for this expression ....).
