Performance Tuning / RAC

Hi,
does anybody know recommendable docs, study guides or books covering Performance Tuning or RAC for database 11g.
Thanks in advance.
Uli

Hi Dan,
thanks for your reply. I have downloaded these docs and will read them as soon as possible.
Additionally I'm interested in recommendable books covering performance tuning.
What do you think about "Troubleshooting Oracle Performance", Christian Antognini, Apress? Customer reviews are very positive. However, it is published in 2008. Is it up-to-date? Does anybody know the "Oracle Performance Survival Guide", Guy Harrison, Prentice Hall?
Which performance books are your favorites?
Best Regards
Uli

RAC performance Tuning

HI All,
We are using 5 node RAC. Can anyone please let me which is best book for performance tuning in 11G RAC or SQL tuning.
Thanks in advance.
Regards,

well which is it, RAC tuning or SQL tuning?
who put your 5 node RAC in?
for RAC, this is pretty much all youll want to know. read it, then come back

for SQL tuning, hit the main forum on here for general queries

Data guard performance problem (rac to single instance)

i have a table it has GPS data, and gps table has too many data, 5 millions,
iam using RAC (2 nodes 11gr2). standby database is single instance data guard,
single instance database (standby)'s hardware cpu is lower than RAC machines. rac nodes have (15k) disks, standby has (7200rpm),
so i dont want to use GPS tables on data guard system, i dont want to run GPS table's DML commands (delete, insert), i think it may increase performance,
is it posible? what is your advise?
any feedback makes me happy,
best regards

it's not possible with data guard, but you can use streams or golgengate for this purpose. Have a look at dataguard performance tuning guide. Maybe there is something you can fix on the configuration to be faster.

I don't know an 11g version for these docs but they would still help.

RMAN backup performance tuning

Hi All,
We have oracle 9iR2 two nodes RAC on solaris 9, I am looking for some helpful material on RMAN backup performance tuning, though i went through oracle's official RMAN performance tuning guide, still if there is some really nice material please let me know!
TIA

Oracle Material is the best.
Anyway, the one given below is also a good P&T book.

Report running for long time & performance tuning

Hi All,
(1). WebI report is running for long time.so what are the steps i need to check for it ?
(2). Can you tell me about performance tuning in BO ?
please help me.....
Thanks
Kumar

(1). WebI report is running for long time.so what are the steps i need to check for it ?
The first step is to see if the problem lies in the query on the data source or in webi itself. Depending on the data source there are different ways to extract the query and try to run it against the database. Which source does your report uses?
(2). Can you tell me about performance tuning in BO ?
I would recommend to start by reading the administrator's guide. There is a section about how to improve performance.

Stratos

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.

Performance tuning of BPEL processes in SOA Suite 11g

Hi,
We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
2. Do we need to run stress tests for every BPEL process deployed?
2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
Thanks in advance!
Sritama

1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
You need
pay attention to:
java heap usage vs java heap capacity
java eden usage vs java eden capacity
JDBC pool initial connections vs JDBC pool capacity connections
if you are using linux: top
if you are using aix: topas
2. Do we need to run stress tests for every BPEL process deployed?
yes, you need test each BPEL. You can use "Jmeter" tool.
Download Jmeter from here: Apache JMeter - Apache JMeter&trade;
Other tools:
jstat
jstack
jps -v
Enterprise Manager
WebLogic Console
VisualVM
JRockit Mission Control
3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
I recommend "Oracle SOA Suite 11g Performance Tuning Cookbook" http://www.amazon.com/Oracle-Suite-Performance-Tuning-Cookbook/dp/1849688842/ref=sr_1_1?ie=UTF8&qid=1378482031&sr=8-1&keywords=oracle+soa+suite+11g+performance+tuning+cookbook

[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 tuning in PL/SQL code

Hi,
I am working on already existing PL/SQL code which is written by someone else on validation and conversion of data from a temporary table to base table. It usually has 3.5 million rows. and the procedure takes arount 2.5 - 3 hrs to complete.
Can I enhance the PL/SQL code for better performance ? or, is this OK to take so long to process these many rows?
Thanks!
Yogini

Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.

Also this informative thread can give you more ideas:

as well as doing a search on 10046 at AskTom, http://asktom.oracle.com will give you more examples.

Performance tuning in XI, (SAP Note 857530 )

Could any one pls tell me where to find sap notes.
I am looking for "SAP Note 857530 "
Integration process performance(in sap XI).
or how can I view the performance of the integration process ? or exactly how performance tuning is done.
pls help,
Best regards,
verma.

Hi,
SAP Note:
Symptom
Performance bottlenecks when executing integration processes.
Other terms
ccBPM
BPE
Performance
Integration Processes
Solution
This note refers to all notes that are concerned with improving the performance of the ccBPM runtime.
This note will be continually updated as improvements are made.
Also read the document "Checklist: Making Correct Use of Integration Processes" in the SAP Library documentation, on SAP Service Marketplace, and in SDN; it contains information about performance issues to bear in mind when you model integration processes.
Refer to the appended notes and maintain the default code changes by using SNOTE, or by importing the relevant service packs. Note that some performance improvements cannot be implemented by using SNOTE and are instead only available in service packs.
