EBS Performance Check

Hi,
The database I am currently working on is about 400Gb. There is lot of load during month end period and even more during financial year end. On a regular basis,if we confront performance issues , we find more CPU and I/O consuming sessions and accordingly take a call on them. But at times the data uploaded and active sessions are so very high that even after recognising and terminating the I/O and CPU consuming sessions,performance issues still surface. Kindly advice me what other factors should i check like resources allocated,network tests etc. so that action can be taken accordingly. My application version is 12.0.6 and database version is 10.2.0.4.
Also DB and CAR are on one node and web and forms on the other.
Thanks,
rdxdba

Hi;
It consider many reason(hardware, settings ,network etc) But i suggest please check below thread which is posted by Hussein Sawwan, if you have performance problem you can check notes&advice in below threads.

Performance Check - ABAP and Database color bars

Hello everyone,
When i go for the performance check of my object, i see Database in red bar and ABAP in green bar.
The smaller the difference between these two bars, the better.
But what does the color mean ? ( Somethimes the smaller bar is Red )
Thanks

Here is the explanation (depends % of total) in [sap library - SE30|http://help.sap.com/saphelp_nw2004s/helpdata/en/c6/617d2ae68c11d2b2ab080009b43351/frameset.htm]

NO, it depends completely of what does your program!

EBS performance impact using it as a Data Source

I have a quick question on EBS performance. If I set up the EBS Database as a data source for SSRS (SQL Server Reporting Services), would there be a performance impact on EBS, due to SSRS accessing EBS Data for reports generation? Now, I know there'll always be a hit depending on the volume of data being accessed. But, my question is, will it be significantly higher using an external reporting tool using an ODBC connection rather than native XML Publisher.

Tough to answer without looking at data; my suggestion would be to have a test EBS environment setup, get permission from the vendors to run performance test without buying license - compare AWRs from both scenarios and then decide.
Generally speaking, native XML publisher (BI Publisher) has less of database performance hit than external reporting tools using ODBC.
Hope this helps.

Performing check and potential update for status control table

Cheers Experts,
I searched in the forum, but I didn't find an answer.
I'm working on a 3.0B BW system.
After updating from PSA to an ODS, in the log I see the following line:
"Performing check and potential update for status control table" and double clicking on it, it says:
If data is loaded into an InfoCube, or existing data is edited (aggregated/compressed/deleted/got from a DataMart), then there is a change in the potential reportability of the data , or the possibility of deleting data by request, or of aggregating or compressing.
This status of each one of these Cubes is stored in a status table, that is updated when there is any change to the status of a request in the Cube.
The system now analyzes the requests in the Cube and compares the calculated status with the status table.
If deviations from the status table arise then you are given the option of adjusting the status table.
I have 2 questions:
1) What is BW doing, mainly because I'm working on an ODS and not an Infocube?
2) What can I do to reduce its execution time, since it lasts several minutes?
Thanks and greetings.
Roberto

Roberto, did you ever find an answer to your question? We also are experiencing long runtimes during this particular process running 3.x deltas from ODS to ODS and cubes.

Performance checking inside the source code

performance checking inside the source code who to check it.
thanks and regards
chandra sekhar

I guess you are asking how to check it, then here is the answer
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

Performance Check in Client transport

What is This performance check in Client Transport?

Hi
Remote client copy: Before the client copy process is started, a consistency check is automatically made. If inconsistencies are detected, the copy process is not started and an error message is logged. You can also perform the consistency check yourself with the RFC System Comparison pushbutton.
Client transport: If an RFC connection can be established between the systems, you can use the report RSCLICHK to compare the structures. If they differ, transport errors and inconsistencies may occur. You can run the program directly in the transaction SCC8 with the RFC System Check pushbutton.
Pls see this link.

Performance check for status control table

Hi,
When ever we activate any ODS or delete the request ,a message 'Performance Check for Status control Table ' appears.
What does it mean?Please explain what is status control table and how it performs?
Thanks & Regards,
Dinakar.

Hi,
This message is not a issue in itself. It is just a SAP message which means that the system is checking/updating the system tables to carry out the operation whether it can be done or not.
If your loads are failing at this step or after this message there can be many reasons, check some of the possible reasons below
Performing check and potential update for status control table
Update from PSA error in Process Chain
problem in deleting request
Reporting not available ,even if Data is sucessfully loaded into DT
Hope this helps,

Set Safari To Always Perform Check If Default Browser When Starting

I want to set Safari to always perform check if it is the default browser every time it starts.
The first time I opened Safari, I asked it not to check to see if it is the default browser. Now, I do not find any way to change that setting back to ask it to perform this check every time Safari starts.
Message was edited by: Yank7

HI,
You can change that setting by going to Safari/Preferences and select the General tab.
Click the pop up menu where you see: Default web browser
*"perform this check every time Safari starts"*
If you click the Safari icon in your Dock, it's going to open Safari regardless, same with Firefox or any other browser you might use. Once it's launched, there's no option available.

Performance check keeps repeating

My A665-S6056 was just factory restored, but upon completion it started its performance check, and has been completing it roughly every 10-15 minutes, for the last 15 hours. Is there anyway to stop this without a hard shutdown?

Because you've just done a recovery, you may just want to hard shutdown and perform another recovery.

What EBS performance gains can I expect moving non-x86 (sun?) to x86?

Hi,
I was hoping some of you would please share any general performance gains you encountered by moving your EBS from non-x86 to x86. I'm familiar with the benchmarks from tpc.org and spec.org. The users however measure performance on how long it takes for a request to complete. For example, when we moved from our EBS from a two node sun E3500 (4*450 sparc II 8GB memory) to a two node v440 (4*1.28ghz sparc IIIi 8GB memory), performance doubled accross the board with a three year pay back.
I am trying to 'guesstimate' what performance increase we might encounter, if any, moving from sun sparc to x86. We'll be doing our first dev/test migration the first half of '08, but I thought I'd get a reading from all of you about what to expect.
Right now we're planning on going with a single-node, 6 cpu dual core 3Ghz x86, 16GB ram. The storage is external RAID 10. We process approximately 1000 payroll checks bi-weekly. Our 'Payroll Process' takes 30min to complete. Similarly, 'Deposit Advice' takes about 30min to complete. Our EBS database is a tiny 200GB, we have a mere 80 concurrent users, and we run HRMS, PAY, PA, GL, FA, AP, AR, PO, OTL, Discoverer.
Thanks for your feedback. These forums are great.

Markus and David,
First let me thank you for your posts. :-).
Markus:
Thank you for the tip. However, I usually do installations with a domain adm user. It does a lot of user switching, yes, but then it only switches to users created by SAPINST, that is most of the time it is switching to <sid>adm, which sounds perfect. At the time of my post I had been setting some environment variables so as to try to get the procedure to distribute the various pieces and bits (saparch, sapbackup, saptrace, origlogs and mirror logs, datafiles, etc. exactly where I wanted them and not where the procedure wants them) so I ended up by using <sid>adm to perform the DB instance installation and not the domain adm user I had installed CI with (I forgot to change back). When I noticed I figured it wouldn't make a difference since it usually switches to <sid>adm anyway. However, for the next attempts I settled on ny initially created dom adm user and no change to the results. OracleService<SID> usually logs on as a system account so the issue doesn't arise, I think.
and
David:
The brackets did it. Thank you so much. It went further and only crashed later, I don't usually potter around sdn, so I'm not familiar with the workings of this, I don't know how to reply separately to the posts and I don't know how to include a properly formatted post (I've seen the Plain Text help but I hate to bother with sidetrack details) so I apologize to all for the probably-too-compact jumble that will come out when I post this. I am now looking at the following problem (same migration to 64) so I fear I may have to close this post and get back with a new one if I can't solve this next issue.

EBS performance?

Dear all,
The EBS are suddenly very slow.... how can I know what are the processes are running?
Or any hints why the performance are very slow.
Thanks,
Amy

Hi amy;
1. Please see if any process is consuming high cpu.
Answer: How can I see this.... I am using AIX server with database 9.2.0.3 database.Try to use topas command for see CPU usage
Check your database it has any lock(If you use toad from tool bar Database>>Monitor>> Session Browser>> Locks)
Check tablespace usage,
If all above is okey and if u havent change nothing before you got performance issue, try to stop appl and db and restart all(if its possible restart your server)
If you still have performance issue please check:

Performance check after CPU

Dear colleagues,
Is any posilble check or test (benchmark) of DB performance before and after CPU patching?
Any testing SAP or SQL report, which makes a load on DB?
Thank you for advice.
Best Regards
Jakub Vaněk

> Is any posilble check or test (benchmark) of DB performance before and after CPU patching?
> Any testing SAP or SQL report, which makes a load on DB?
Those test would be synthetic and may or may not reflect your current environment.
I'd check some long running reports in your environment if you see any difference.

Perform check after release step of purchasing requisition

Hi,
does anybody have a suggestion where to place best some logic which needs to be performed after a release step is performed successfully.
background: we use different types of Purchase requisitions, while each one is assigned to a static release strategy. I like to change it in more dynamic way by adding certain logic after a release step is performed.
example: if preceeding release step was 10 and purchase requisition is of type x then check purchase value and account assignment in order to process the current stepo automatically.
Currently the logic runs during a nightly job, but I would like to add it immediately after a release has been performed. I would imagin something like user exit, BusinessAddIn, or an event which I can use assign the job.
Can anybody suggest something?
Thanks in advance
Best regards
Torsten
