Performance tuning in CRM server

Hi everyone,
My CRM server working very slow. Idont know the exact reason. My server configuration IBM Xeon processor 3 Ghz 3GB RAM.There are about 25 users. Is this problem with SAP or Hardware.If any one have performance tuning document plz post it.
Thanks,
Murali

Chech the following:-
Processor usage
Ram usage
background jobs
how many user at a time
what kind of job they do
Any Network Problem
Increse Work Processor
increase Virtual Ram
And for 25 users, You need System with 2 CPU and 4 Gb Ram

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.

IIR 2.8.0.7 performance tuning suggestions / documents for Oracle 11?

Would we have any hints or white papers that would support a customer in IIR matching server tuning for initial load performance,
beyond the Siebel specific
Performance Tuning Guidelines for Siebel CRM Application on Oracle Database (Doc ID 781927.1)
which does NOT generate any statistics on the Informatica Schema?
Customer is starting production data load into Siebel UCM of over 5 million customer records . Their current bottle neck seems to be IIR queries and high IIR host resources usage.
This would be for Siebel 8.1.1.4 [21225] on Oracle 11.1.0.6; I currently do not know if ACR 475 with its EBC access is used or not; I'd be looking for any performance tuning suggestions on the Informatica & database side - I have not found anything helpful in the informatica knowledgebase and in the 2.8.0.7 docs the only performance tuning suggestions seem to be on IDT loads.
Obviously performance can be influenced by the matching fields used, but this customer will be looking for performance tuning suggestions keeping the matching fields and thresholds they got approved from the business side.
Any documents we could share?

Hi Varad,
Well, Oracle Metalink actually got it fixed for me! Got to give them credit.
I ran the 1st bit of SQL they sent me and it fixed it so I think it was only cosmetic. I've enclosed all of their response in case others may find themselves in similar situation.
Thanks again for YOUR help too.
Perry
==========================================================
1. Do you see any invalid objects in the database?
2. Please update the SR with the output of running the commands below
1.Connect as SYS.
set serveroutput on (This will let you see if any check fails)
exec validate_apex; (If your version is 2.0 or above)
If all are fine, the registry should be changed to VALID for APEX and you should see the following
message:
PL/SQL procedure successfully completed.
Note : The procedure validate_apex should always complete successfully.
With serveroutput on, it should show why Application Express is listed as invalid.It should show output like:
FAILED CHECK FOR <<obect_name>>
Or
FAILED EXISTENCE CHECK FOR <<object_name>>

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.

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)

Performance tuning in ODI

Hi,
Can any help how to do performance tuning in ODI. What are the procedure for performance tuning. What needs to checked for performace tuning. Is there any document for ODI performace tuning.
Thanks,
Gnanamanju

Hi Gnanamanju,
Let me try to contribute a little,
ODI performance strategy tells,
1. Its recommended to run the AGENT in the target host rather than source. In case if your target is a remote host.
2.Selecting appropriate KMs to load data, for example, if its a simple file to oracle transfer, its recommended to use native DB utilities like SQLLDR, External Table and so on.
3. In case, if your staging and target are on the same server then make sure in Physical architecture your selected the correct schema (Data Schema and Work Schema)
4. Right area of execution of joins and filters. If your source has more records then use the filter condition to be executed on SOURCE rather staging.
5. Increase the Array Fetch Size and Batch Fectch Size of your Data server ( so that agent can accordingly fetch/insert the data)
And more....
Thanks,
Guru

BPM 11g Performance Tuning

HI Experts,
Can some one help me to tune a oracle bpm engine 11g (11.1.1.5)
Any tuning recommendation for a mid-size engine
(if some one really implemented which gives some significant performance improvement)
Tried almost everything but engine is really slow with 5 concurrent user.
Please don’t give url to middleware performance tuning guide. 
Configuration:
Hardware
Sparc-t3-2
1.65 GHz
2 Core virtual
Memory 16 GB
Setting – Total 2 containers. 1 manage server each, 1 Admin.
Heap space 4 GB, Perm Space – 1gb
Client :
50 Concurrent User.
10 BPMN Process (each process got around 10-12 activity), 8 BPEL Process,
1000-1500 Live Instances as of now. Need to cater more in future. (around 50,000))

Oracle Support Document 1456488.1 (Slow startup of WebLogic Servers on SPARC Series: T1000, T2000, T5xx0 and T3-* ) can be found at:

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.

Hi,
have a look into these link.it may helpful to you.

Hello Jaya,
Will provide some point which will increase the performance of the program:
1.     VBAK & VBAP are header & item table. And so the relation will be 1 to many. In this case, you can use inner join instead multiple select statement.
2.     If you are very much confident in handling the inner join, then you can do a single statement to get the data from VBAK, VBAP & VBKD using the inner join.
3.     Before using for all entries, check whether the internal table is not initial.
And sort the internal table and delete adjacent duplicates.
4.     Sort all the resultant internal table based on the required key fields and read always using the binary search.
You will get a number of documents where you can get a fair idea of what should be done and what should not be while doing a program related to performance issue.
Also you can have number of function module and BAPI where you can get the sales order details. You can try with u2018BAPISDORDER_GETDETAILEDLISTu2019.

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

SAP CRM Performance tuning

From where can I get information or documents how to do performance tuning in SAP CRM?

Hi, Performance Tuning a SAP system is unique in every environment, also there are many area's in SAP to tune even area's outside SAP, eg... your Operating System/Network/Client Machines/Virtual Landscape/Cloud.
I recommend that you engage in a performance testing execise which will identify what area of your SAP Landscape needs tuning, first you need to identify the bottleneck before you can tune it.
The way the question was posed is exactly the same as wanting to fix a car but you have no idea which part of the car to fix...
*LoadRunner is an excellent tool to simulate virtual work load on an SAP environment*
