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.

What are the best practices for Database management and performance tuning?

Hello,
I want to ensure that I am using the best practices for managing and maintaining our Database.
Is there any documentation out there that outlines how to maintain and ensure top performance out of our database?
Thank you!
John Sefton

I appreciate the responses, however this is not the information I am looking for.
I am specificaly looking for best practices invloving the managment and performance tuning.
Example: are their tools that I can install that will monitor the size and response time of the database and alert me if there is degradation in performance?
Are there specific periodic activities I should be doing to garuntee that my database will continue to function that way it is supposed to?
Or is this a fire and forget solution that does not need this attention?

Performance Tuning on a table where WHERE clause is having only PK columns

Hi folks!!
Here is the gotcha!!!!
I am having a table, named X, with primary key columns A and B.
I running a packaged procedure in which there is a SELECT statment to get the record from the table X with WHERE condition on A and B columns. Now the problem is, the package is taking too much amount of time to get executed.
Eventually, I used TKPROF utility on the trace file of that package execution.
The trace file is showing that huge amount of time is spent on the SELECT statement of table X, as I said above.
I am baffled why it is taking that much of time eventhough the columns in the WHERE clause are Primary Key columns only and that too there are in the sequential order as that of in primary key contituent sequence.
I would be very grateful to you guyz... plz help me out of this one....

Reg: Process Chain, query performance tuning steps

Hi All,
I come across a question like, There is a process chain of 20 processes.out of which 5 processes are completed at the 6th step error occured and it cannot be rectified. I should start the chain again from the 7th step.If i go to a prticular step i can do that particular step, How can i start the entair chain again from step 7.i know that i need to use a function module but i dont know the name of FM. Please somebody help me out.
Please let me know the steps involved in query performance tuning and aggregate tuning.
Thanks & Regards
Omkar.K

Hi,
Process Chain
Method 1 (when it fails in a step/request)
/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
How is it possible to restart a process chain at a failed step/request?
Sometimes, it doesn't help to just set a request to green status in order to run the process chain from that step on to the end.
You need to set the failed request/step to green in the database as well as you need to raise the event that will force the process chain to run to the end from the next request/step on.
Therefore you need to open the messages of a failed step by right clicking on it and selecting 'display messages'.
In the opened popup click on the tab 'Chain'.
In a parallel session goto transaction se16 for table rspcprocesslog and display the entries with the following selections:
1. copy the variant from the popup to the variante of table rspcprocesslog
2. copy the instance from the popup to the instance of table rspcprocesslog
3. copy the start date from the popup to the batchdate of table rspcprocesslog
Press F8 to display the entries of table rspcprocesslog.
Now open another session and goto transaction se37. Enter RSPC_PROCESS_FINISH as the name of the function module and run the fm in test mode.
Now copy the entries of table rspcprocesslog to the input parameters of the function module like described as follows:
1. rspcprocesslog-log_id -> i_logid
2. rspcprocesslog-type -> i_type
3. rspcprocesslog-variante -> i_variant
4. rspcprocesslog-instance -> i_instance
5. enter 'G' for parameter i_state (sets the status to green).
Now press F8 to run the fm.
Now the actual process will be set to green and the following process in the chain will be started and the chain can run to the end.
Of course you can also set the state of a specific step in the chain to any other possible value like 'R' = ended with errors, 'F' = finished, 'X' = cancelled ....
Check out the value help on field rspcprocesslog-state in transaction se16 for the possible values.
Query performance tuning
General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particual day > check query execution time.
/people/andreas.vogel/blog/2007/04/08/statistical-records-part-4-how-to-read-st03n-datasets-from-db-in-nw2004
/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memoery will decrease the loading time of the report.
Run reporting agent at night and sending results to email.This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
Also try
1. Use different parameters in ST03 to see the two important parameters aggregation ratio and records transferred to F/E to DB selected.
2. Use the program SAP_INFOCUBE_DESIGNS (Performance of BW infocubes) to see the aggregation ratio for the cube. If the cube does not appear in the list of this report, try to run RSRV checks on the cube and aggregates.
Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. --- sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.
Refer.

http://help.sap.com/saphelp_nw70/helpdata/en/60/f0fb411e255f24e10000000a1550b0/frameset.htm
4. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.
5. In BI 7 statistics need to be activated for ST03 and BI admin cockpit to work.
By implementing BW Statistics Business Content - you need to install, feed data and through ready made reports which for analysis.

You can go to T-Code DB20 which gives you all the performance related information like
Partitions
Databases
Schemas
Buffer Pools
Tablespaces etc
use tool RSDDK_CHECK_AGGREGATE in se38 to check for the corrupt aggregates
If aggregates contain incorrect data, you must regenerate them.

Can anyone plz tell me the steps for performance tuning.

hello friends
what is performance tuning?
can anyone plz tell me the steps for performance tuning.

Hi Kishore, this will help u.
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.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on the SPFLI table in our test program is mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
Need for performance tuning
In this world of SAP programming, ABAP is the universal language. In most of the projects, the focus is on getting a team of ABAP programmers as soon as possible, handing over the technical specifications to them and asking them to churn out the ABAP programs within the given deadlines.
Often due to this pressure of schedules and deliveries, the main focus of making a efficient program takes a back seat. An efficient ABAP program is one which delivers the required output to the user in a finite time as per the complexity of the program, rather than hearing the comment I put the program to run, have my lunch and come back to check the results.
Leaving aside the hyperbole, a performance optimized ABAP program saves the time of the end user, thus increasing the productivity of the user, and in turn keeping the user and the management happy.
This tutorial focuses on presenting various performance tuning tips and tricks to make the ABAP programs efficient in doing their work. This tutorial also assumes that the reader is well versed in all the concepts and syntax of ABAP programming.
Use of selection criteria
Instead of selecting all the data and doing the processing during the selection, it is advisable to restrict the data to the selection criteria itself, rather than filtering it out using the ABAP code.
Not recommended
Select * from zflight.
Check : zflight-airln = LF and zflight-fligh = BW222.
Endselect.
Recommended
Select * from zflight where airln = LF and fligh = 222.
Endselect.
One more point to be noted here is of the select *. Often this is a lazy coding practice. When a programmer gives select * even if one or two fields are to be selected, this can significantly slow the program and put unnecessary load on the entire system. When the application server sends this request to the database server, and the database server has to pass on the entire structure for each row back to the application server. This consumes both CPU and networking resources, especially for large structures.
Thus it is advisable to select only those fields that are needed, so that the database server passes only a small amount of data back.
Also it is advisable to avoid selecting the data fields into local variables as this also puts unnecessary load on the server. Instead attempt must be made to select the fields into an internal table.
Use of aggregate functions
Use the already provided aggregate functions, instead of finding out the minimum/maximum values using ABAP code.
Not recommended
Maxnu = 0.
Select * from zflight where airln = LF and cntry = IN.
Check zflight-fligh > maxnu.
Maxnu = zflight-fligh.
Endselect.
Recommended
Select max( fligh ) from zflight into maxnu where airln = LF and cntry = IN.
The other aggregate functions that can be used are min (to find the minimum value), avg (to find the average of a Data interval), sum (to add up a data interval) and count (counting the lines in a data selection).
Use of Views instead of base tables
Many times ABAP programmers deal with base tables and nested selects. Instead it is always advisable to see whether there is any view provided by SAP on those base tables, so that the data can be filtered out directly, rather than specially coding for it.
Not recommended
Select * from zcntry where cntry like IN%.
Select single * from zflight where cntry = zcntry-cntry and airln = LF.
Endselect.
Recommended
Select * from zcnfl where cntry like IN% and airln = LF.
Endselect.

Performance Tuning in IR

Hello All,
We have created some reports using Interactive Reporting Studio. The volume of data in that Oracle database are huge and in some tables of the relational database are having above 3-4 crores rows individually. We have created the .oce connection file using the 'Oracle Net' option. Oracle client ver is 10g. We earlier created pivot, chart and report in those .bqy files but had to delete those where-ever possible to decrease the processing time for getting those report generated.
But deleting those from the file and retaining just the result section (the bare minimum part of the file) even not yet helped us out solving the performance issue fully. Still now, in some reports, system gives error message 'Out of Memory' at the time of processing those reports. The memory of the client PCs,wherefrom the reports are being generated are 1 - 1.5 GB. For some reports, even it takes 1-2 hours for saving the results after process. In some cases, the PCs gets hanged at the time of processing. When we extract the query of those reports in sql and run them in TOAD/SQL PLUS, they take not so much time like IR.
Would you please help us out in the aforesaid issue ASAP? Please share your views/tips/suggestions etc in respect of performance tuning for IR. All reply would be highly appreciated.
Regards,
Raj

SQL + & Toad are tools that send SQL and spool results; IR is a tool that sends a request to the database to run SQL and then fiddles with the results before the user is even told data has been received. You need to minimize the time spent by IR manipulating results into objects the user isn't even asking for.
When a request is made to the database, Hyperion will wait until all of the results have been received. Once ALL of the results have been received, then IR will make multiple passes to apply sorts, filters and computed items existing in the results section. For some unknown reason, those three steps are performed more inefficiently then they would be performed in a table section. Only after all of the computed items have been calculated, all filters applied and all sorts sorted, then IR will start to calculate any reports, charts and pivots. After all that is done, the report stops processing and the data has been "returned"
To increase performance, you need to fine tune your IR Services and your BQY docs. Replicate your DAS on your server - it can only transfer 2g before it dies, restarts and your requested document hangs. You can replicated the DAS multiple times and should do so to make sure there are enough resources available for any concurrent users to make necessary requests and have data delivered to them.
To tune your bqy documents...
1) Your Results section MUST be free of any sorts, filters, or computed items. Create a staging table and put any sorts or local filters there. Move as many of your computed items to your database request line and ask the database to make the calculation (either directly or through stored procedures) so you are not at the mercy of the client machine. Any computed items that cannot be moved to the request line, need to be put on your new staging table.
2) Ask the users to choose filters. Programmatically build dynamic filters based on what the user is looking for. The goal is to cast a net only as big as the user needs so you are not bringing back unnecessary data. Otherwise, you will bring your server and client machines to a grinding halt.
3) Halt any report pagination. Built your reports from their own tables and put a dummy filter on the table that forces 0 rows in the table until the report is invoked. Hyperion will paginate every report BEFORE it even tells the user it has results so this will prevent the user from waiting an hour while 1000s of pages are paginated across multiple reports
4) Halt any object rendering until request. Same as above - create a system programmically for the user to tell the bqy what they want so they are not waiting forever for a pivot and 2 reports to compile and paginate when they want just a chart.
5) Saved compressed documents
6) Unless this document can be run as a job, there should be NO results stored with the document but if you do save results with the document, store the calculations too so you at least don't have to wait for them to pass again.
7) Remove all duplicate images and keep the image file size small.
Hope this helps!
PS: I forgot to mention - aside from results sections, in documents where the results are NOT saved, additional table sections take up very, very, very small bits of file size and, as long as there are not excessively larger images the same is true for Reports, Pivots and Charts. Additionally, the impact of file size only matters when the user is requesting the document. The file size is never an issue when the user is processing the report because it has already been delivered to them and cached (in workspace and in the web client)

Need clear steps for doing performance tuning on SQL Server 2008 R2 (DB Engine, Reporting Services and Integration Services)

We have to inverstigate about a reporting solution where things are getting slow (may be material, database design, network matters).
I have red a lot in MSDN and some books about performance tuning on SQL Server 2008 R2 (or other) but frankly, I feel a little lost in all that stuff
I'am looking for practical steps in order to do the tuning. Someone had like a recipe for that : a success story...
My (brain storm) Methodology should follow these steps:
Resource bottlenecks: CPU, memory, and I/O bottlenecks
tempdb bottlenecks
A slow-running user query : Missing indexes, statistics,...
Use performance counters : there are many, can one give us the list of the most important
how to do fine tuning about SQL Server configuration
SSRS, SSIS configuration ?
And do the recommandations.
Thanks

Hello,
There is no clear defined step which can be categorized as step by step to performance tuning.Your first goal is to find out cause or drill down to factor causing slowness of SQL server it can be poorly written query ,missing indexes,outdated stats.RAM crunch
CPU crunch so on and so forth.
I generally refer to below doc for SQL server tuning
http://technet.microsoft.com/en-us/library/dd672789(v=sql.100).aspx
For SSIS tuning i refer below doc.
http://technet.microsoft.com/library/Cc966529#ECAA

When I face issue i generally look at wait stats ,wait stats give you idea about on what resource query was waiting.

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.

SAP Conversion Agent - Performance Tuning

Hi Experts,
We are working with SAP Conversion agent..we have developed several scenarios on that...
But, Now we are worried about the performance issues on the same.
Can anybody share their experience on SAP Conversion Agent and any performance tuning guide on SAP Conversion Agent.

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,
Jithin

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.
