Oracle 11g performace tunning book
Please suggest the good book for oracle 11g performace tunning ,

Define what do you mean by "complete" . If you are willing to read just one book to read all about Performance Tuning, well guess what, there isn't any. Every book that you are going to read from a good author, like the one suggested by Martin , is going to be useful . And just so you know, 12c is the latest release.

1.DB side (if any parameters need to change then please suggest us)
2.Server side tunning
3. App pool tunning and IIS level tunning (if any please suggest me).
4.Windows O/S level tunning..(Software level tunning and hardware level ).
ThanksHi,
What are the performance issues that you are having and what is the version of DRM you are on?
Thanks

Please help me on this.Hi,
As SAP recommends, do not create/declare internal tables with header line. Create an explicit work area for internal tables and read into the work area or use field symbols (ASSIGNING).
Also, when performing READ command on internal table, use BINARY SEARCH. However, precaution, always sort the internal table with the fields used for read in WITH KEY clause.

Enq: TX - row lock contention problem
Hi ,
Db version 10.2.0.4
os solaris.
i have upgraded my database from 9.2.0.4 to 10.2.0.4 by using exp/imp as my database is small.
I have created new instance of 10g and changed parameter values as 9i(as required). then imported from 9i to 10g instance.
After importing in 10g instance we are face application wide performance problem..the response time of the applicatoin was very slow...
i have taken awr report of various times and have seeen
SELECT puid,ptimestamp FROM PPOM_OBJECT WHERE puid IN (:1) FOR UPDATE
this query is causing the problem..enq: TX - row lock contention

VamshiThe CBO has changed substantially between 9.2.x and 10.2.x. Pl see MOS Doc 754931.1 (Cost Based Optimizer - Common Misconceptions and Issues - 10g and Above). Pl verify that statistics have been gathered and are current - pl see MOS Doc 605439.1 (Master Note: Recommendations for Gathering Optimizer Statistics on 10g).
Looking at your output, it seems to me that the database is entirely CPU-bound. 86.3% of time is spent on CPU. The last 5 SQL statements in the output, all of the elapsed time is spent on CPU.
Pl post your init.ora parameters, along with your hardware specs. This question might be more appropriate in the "Database - General" forum.

Performance reports and measures for Online Trading Customer's databases
We have a client from online trading commodity domain. there databases are running in healthy stat.
We on daily basis share with them AWR report of time span 9:30AM to 10:30AM (peak trading hours).
can you suggest what all recommendadtions we can include in this AWR report or how we can study on daily basis this AWR report extracted to mention recommendation to customer.
apart from this what other performance reports we can share with customer which will make cilent view their database stat in terms of performace tunning and all.
We can share daily database checks and all but I am trying to have some good performance end reports which can be extract to share with client??
What performace reports you are sharing or can suggest in this regards??
Thanks friends in advance.Hi

I have written a few blog posts about AWR analysis (http://savvinov.com/category/awr/) -- some of them may be useful to you. However, AWR reports are not so good for monitoring purposes. Monitoring is about trends -- AWR doesn't have that. Plus, application performance should be measured in its native metrics (KPIs or "key performance indicator"). For instance, for an online shop that would be the number of orders processed, average time it takes to process an order etc. Low level stats such as the number of table scans per unit time or IO stats doesn't really tell whether or not an application is performing satisfactorily.
From the database point of view, a simple overview of the OEM Performance Page should be enough to get a basic idea whether the database is ok.
can you suggest what all recommendadtions we can include in this AWR report or how we can study on daily basis this AWR report extracted to mention recommendation to customer.I've seen a lot of such recommendations -- 99% of them are garbage, and the customers treat it accordingly. Unless there are clear signs of a performance issue, recommendations are generally neither necessary, nor possible (without additional information about the application). Ain't broken -- don't fix it.
apart from this what other performance reports we can share with customer which will make cilent view their database stat in terms of performace tunning and all.

Without an SLA and/or specific complaints from the user there is little you can do about database performance, except for when something obvious shows up on the report.

Hi,
Our company doesn't currently have oem installed on production. This will be done in March. Right now I am working with the sqltune package to access the database on the dev server before I run it on production. I was running the following procedure below and requested the GOLDUSER schema.
Down in the load_sqlset procdure I think I have the load_option and update_option set to the correct values. I could be wrong though. By setting these all I want is to extract the old sql statements and performace tune them.
I get those sql statements listed out and also I get a different named schema under "tables with new potential indices" (LEADUSERS).
Should I be concerned with this? Would someone just look this procedure over to see if it is correct?
I would appreciate your help in this matter.
Thanks in advance.

Hey Everyone :)
Over the last 2 weeks, as some of the regulars might know, ive been compiling a web crawler, 1 week ago my webcrawler took 37 mintues to find 14000 sites and search 1150 of them, today after just a little bit of code performace tunning (thanks to members on this forum) my webcrawler now finds 5133 sites a minutes and searches 560 of them (averages).
So instead of taking 37 minutes to find 14000 sites it now takes me 3 minutes to find 15000 sites and search 560 of them.
Im running Windows XP, now processor (not dual, which would allow parralell threads haha i wish i had it though) and 512 ram.
Now the reason im writing this is i need to know if my currents stats are as fast as i can go, or can i still go faster?
Thanks in advance, NickYeah, I remember. Someone already pointedt out that multithreading will be faster because you'd reduce the impact of externally induced wait cycles. If you'd like to see whether your source can be tuned for performance, use a profiling tool. But bear in mind:
1) optimization might not be worth the effort taken
2) it also might make your code unreadable and more difficult to maintain
3) the bottleneck's still the connection to the webserver and the resulting traffic. -

Saad NisarHi Saad,
This is a standard program(SAPMV75A), RIGHT? . Normal tools in sap for performace analysis are
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.
Kindly please take an ABAP'ers help.
Regards,
Ram Pedarla -
This is the SQL i would like to tune for performace...
The table structure is given below.
The table has about 5 million rows.
On the first day, load_flag has all the rows as 'I'.
Then from the second day onwards only around 10% of records will be between Load_Start_Time and Load_End_Time. Among these around 40% will have Record_key like 'TP%'. And among those most of the records (95%)will have load_flag as 'U' and a very few (5%) as 'I'. At present there are unique and primary key indexes on record_key. Please advice me whether it's better to go for an index on any of these columns and what type would be better. I thought it would help to have a bit map index on load_flag and a function base index on SUBSTR (RECORD_KEY).
Also pls. let me know if the order of predicates is right.
Thanks in advance.

));I would like to discuss a bit more how a composite index is used. This is not anymore the question of the OP, but I think it will deepen my understanding and maybe that of others as well.
So we have this situation to start with.
* A select on two different columns.
* An index on each column would lead to an INDEX RANGE SCAN because of the where condition.
* Instead of 2 indexes where only one would be used (not considering bitmap conversions), we add a composite index on both columns.
* The CBO will choose and access the index.
Question is: How is this access is done in detail?
So 400 rows come out of the index range scan.
This would not be possible if it only scanned one of the two predicates. I agree. The output of the index seem to be only those (400) rows that fit with the where clause on both columns.
This is supported by the fact that an Index only access is possible when we select only information that is in the index (Oracle 9i output).
SQL> explain plan for
2 select record_key
3 from mytable
4 where stg_update_date_time >= to_date('2007-11-11','yyyy-mm-dd')
5 and stg_update_date_time < to_date('2007-11-12','yyyy-mm-dd')
6 and record_key like 'TP%'

Explained.
SQL> select * from table(dbms_xplan.display);
PLAN_TABLE_OUTPUT
| Id | Operation | Name | Rows | Bytes | Cost |
| 0 | SELECT STATEMENT | | 160 | 2400 | 2 |
| 1 | INDEX RANGE SCAN | I1 | 160 | 2400 | 2 |
Note: cpu costing is off, PLAN_TABLE' is old version
9 rows selected.
SQL> Unfortunately I don't see the filter operation, probably because the plan table is old in my system.
The index is build on columns "stg_update_date_time" and "record_key". So it must access these columns in that order.
I think, that maybe the range scan is done on the date column and then a further access/filter operation is done to rule out any index entries (leaf nodes) that do not fit with the LIKE 'TP%' expression.
Since I expect that is is faster to access the data in the index than in the table this should improve performance quite a bit. It is not the same access plan/speed however as with a clause like this:
SQL> select * from table(dbms_xplan.display);
PLAN_TABLE_OUTPUT
| Id | Operation | Name | Rows | Bytes | Cost |
| 0 | SELECT STATEMENT | | 1 | 520 | 3 |
| 1 | TABLE ACCESS BY INDEX ROWID| MYTABLE | 1 | 520 | 3 |
| 2 | INDEX RANGE SCAN | I1 | 1 | | 2 |
Note: cpu costing is off, PLAN_TABLE' is old version
10 rows selected.
SQL> The difference can be seen in the cost estimation.
I hope somebody does understand what I would like to point at.
Result of this considerations:
1) Composite index can be used
2) The index is used as a range scan on one column and as a filter operation after this access on the second column. This is like an extra select statement inside the index structure.
3) The resulting table access is as small as possible.
4) A faster access plan can be achieved when the first column is accessed with direct (unique) scan on the first and a range scan on the second column.

How to tune the query and difference between CBO AND RBO.. Which is good
Hello Friends,
Here are some questions I have pls reply back with complete description and url if any ..
1)How Did you tune Query,
2)What approach you take to tune query? Do you use Hints?
3)Where did you tune the query and what are the issue with query?
4)What is difference between RBO and CBO? where u use RBO and CBO.
5)Give some information about hash join?
6) Using explain plan how do u know where the bottle neck in query .. how u will identify where the bottle neck is from explain plan .
thanks/KumarHi,

Hello Friends,

1)How Did you tune Query, Use EXPLAIN PLAN to see exactly where it is spending its time, and address those areas.
See the forum FAQ
SQL and PL/SQL FAQ
"3. How to improve the performance of my query?"
2)What approach you take to tune query? Do you use Hints?Hints can help.
Even more helpful is writing the SQL efficiently (avoiding multiple scans of the same table, filtering early, using built-in rather than user-defined functions, ...), creating and using indexes, and, for large tables, partitioning.
Table design can have a big impact on performace.
Look for ways to do part of what you need before the query. This includes denormalizing (when appropriate), the kind of pre-digesting that often takes place in data warehouses, function-based indexes, and, starting in Oracle 11, virtual columns.
3)Where did you tune the query and what are the issue with query?Either this question is a vague summary of the entire thread, or I don't understand it. Can you re-phrase this part?
4)What is difference between RBO and CBO? where u use RBO and CBO.Basically, use RBO if you have Oracle 7 or earlier. -
Dear Friends,
My organisation is using EP 7.0 , where we are using ESS & MSS component.
We are facing lot performace problem in EP 7.0.
Can anybody help me how to tune my EP 7.0 system. what parameter to be consider for tunning.

How can you get your data back on i tunes
Hi i am Justin,
I have i phone and i have i tunes here is my problom. last night i formatted my HP windows 7 computer and i backed up my pictures and backed up i tunes witch i thoght i did becasue i backed it up on my external 500 MB hard drive and with out making a folder and c oping i tunes i only backed up library and before the format i went to edit, preferences and adavaned in i tunes (sorry about the bad spelling) becasue apples's step by step i read and saw the pictures were to go and i thought i can back up i tunes that way. My phone has 333 songs all my pictures apps and contacts and there is no way to re copy from the phone back in to i tunes i do not use i cloud becasue (one i do not want to pay for more space) and 2 the free version tells me i do not have enough space to back it up so i am worried one sync i will lose all my info. these songs are from cd's i have and off the Internet before the courts stopped Napster and Lime Wire. Sos what should i do just unstalli tunes and leave my computer as a re charging stastion? or is there any secret way to get all my things back then this time i can make a folder and do it right in case the next time i have to re format my drive from a problems or need to what is the best case here?
JustinSync is only oneway, from PC to your device. Unless you have the music on your PC, iTunes is going to wipe out what you have on your device if you are syncing to a new library.
You can only transfer Purchased music over to Itunes on your PC.

As for you own music, you may have to use a third party software. A good Free one is called Sharepod which you can download from Download.com here:

I tunes downloads to wrong drive
Hi guys some help please. When I download the latest I tunes 9.1.1 is wants to install to drice "G" which I don't have I want it to download on "C". Any ideas?
Hey there,
One thing you should check is where your iTunes searches for your iTunes folder. Head to iTunes and then Preferences. When the window pops up, head over to the Advanced tab. Near the top of the tab, you will see where iTunes currently locates your Music folder. Click the Change button and then direct it to where the folder is located on your External drive. See if that helps.
