ST04 - Performance Overview

The dat displayed in the screen is not correctly positioned . The values for various headers are displayed at the end/bottom of the screen and not aligned properly with the headers . ERP 6.0 EHP 4 , Netweaver 7.01 is the version

Hi,
Is that happening with all the SAP screen (ex ST02,DB02,ST03 etc.,) or only for ST04 also try to check the option (graphic settings).
Thanks,
Salim

Portal Runtime Error in Performance Overview

Hi Experts ,
I am getting portal runtime error while accessing performance overview and this error is occurring in test system not in prod. I have only passed our custom parameter in "ViewGroup" and "ViewID" , which comes under property Editor of Performance Overview Iview.
Please find the server log :-

RZ20 - Performance Overview memory monitors

I have a question about the values displayed in one of the CCMS monitors.
In RZ20, following this path:
SAP CCMS Monitor Templates
     Performance overview
         <SID>\<SERVER_INSTANCE>
              Memory Management
I do the following:
Click on HeapAct monitor
Click the menu: Views -> Details for Performance Nodes
This appears to give me information that I am after - hourly values. However, I am not sure what the numbers under the hourly values actually represent. I can click on the Number of Measurements Of/From button and the hourly values change - but again, I'm not sure what these numbers are.
Does anyone know what these numbers are telling me?
thanks,
Jeff Henke

Running a copy operation of a large file can indeed take quite some memory, and it can result in that SQL Server will be requested to yield memory. Or even worse, be swapped out the page file, if SQL Server does not react fast enough. Has the service account
for SQL Server been granted the Windows permission Lock Pages in Memory?

ST04 performance question...

Hi,all
My SAP system's ST04 database performance analysis -->Data buffer Quality is 67.5% less than 95%
Busy wait time and CPU time's ratio are 32:68 ,not 60:40
So,how can I adjustment this, thank you!
Edited by: Terry Chiang on Sep 29, 2011 8:33 AM

Hi Terry,
ST04 is a good transaction that SAP has provided for analyzing database performance.
The ratio of Busy wait time to CPU time should ideally be close to 60:40 as you mentioned. If you see very high values (such as 80:20) or in case if less, system performance can be improved using 'wait event tuning'. If the CPU time is significantly higher than 40%, check the CPU utilization on the database server.
Some other factors that you can check for improving the performance are:
Time/User call should be less than 20ms. Note that the value can be much higher due to the inclusion of special idle events which limits the relevance of this data.
Hit ratio (Quality) of the data buffer should be more than 94%. A low hit ratio might be due to small size of the data buffer.Chek SAP note 619188 for a deeper analysis.
Reads/User Calls should be less than 15. If it is too high, check for expensive SQL statements. SAP Note 766349 will be useful to you.
Go to Detail Analysis Menu -> File System Requests and check the average read time (Avg(ms) for Blk Reads) for individual data files or in total (Total under the column). If the values is very high in comparison to 10 ms, check whether the problem can be solved by improving the data distribution or if there is any Disk I/O problem at hardware level.
You can analyse more on disk usage from ST06/OS07 (-> Detail Analysis Menu -> Disk). If the load on the database server's disks is more than 80%, you need to redistribute the data files.
DD-cache quality should be more than 80%; pinratio should be more than 95%; reloads/pin should be lower than 0.04; User/recursive calls should be more than 2. If there is too much deviation in these indicators, you need to increase shared pool size.
Hope the info helps you.
Thanks

Different transaction codes useful for Performance Monitoring

Performance Problems with Web Layouts in web interface

Hello Gurus,
We have a a BPS web interface tool which has the following design:
1> A web interface with several tabs
2> Each tab has around 3-4 input layouts which are dependent on each other
3> In all there are 120-140 layouts that the tool uses...
My questions were in term of performance
1> Is there a limit to how many web layouts you can use per page/tab/view or if SAP recommends specific number of web layouts per page/tab/view ?
2> If there is a limitation...our intention was to convert all the display layouts into BW reports so as to increase the performance of the tool....
3> Would like to know the restriction on the number of users who can log into the tool as a specific point of time ? We may have 50-60 minimum using this tool.
I would appreciate your help in this regard.
Thanks in advance

Hello Rashmi,
Have you got a chance to look at the performance guide and SAP notes on BPS performance. If not here are the details

Database performance: avg. DB time is high

My system is ECC6, MSSQL 2005 64 bit.
I got a ERA report from my solution manager and it showed that we had a performance problem.
Our performance overview is red because of the database performance.
The avg. DB time in ms is 2768890,3. It's very high.
Could you please help us on this issue?
Leo

Hai,
There might number of reasons for high DB time.
Check your I/O statistics, check your table structure, create Indexes if needed for efficient table access.
You can schedule Optimize statistics in DB13 to get the statistics upto date which helps DB to get the best possible way to access data from your DB.
Analyse the DB buffers and adjust them to get optimal performance. (Should be done by experienced DB admins).
Check the below links....

How to get values of Dialog Overview node in RZ20

Hello,
In ECC 6.0.
In T-code RZ20 when i clicked on node EC6
it showed me a tree structure with following nodes below EC6.0
System Configuration
\System Buffers
Change & Transport System
File System
Operating System
Performance Overview
System Errors
Now when i expand the tree node of "Performance Overview" another subnode comes up
"Dialog Overview " inside this node i can see

I want to know from which table or cache value 6585 is coming against EC6\IGATESAP07_EC6_02\...\Dialog\ResponseTime...
Is there any function module, or table or anything from where i can get this value since when ever we refresh ,value changes which indicates might be coming from cache.
how to get this value...
Regards,
Mayank

Dialog\ResponseTime 6585
"The dialog response time consists of the period of time from the request of the dialog to the dispatcher through the processing, to the ending of the dialog in the dispatcher and the transfer of the data to the presentation layer"
This is not buffered as far as I know is measured on demand

DB02 - space overview display zero values

Hi Friends,
When I executed DB02 t-code. I got zero values in the fields (Database, Users, Tablespace, Segments)
I got the same with ST04 -> Space Overview.
So, Please tell me the solution for this.
Thanks & Regards

Hi Varadhu,
As per your guidance, I tried to check SAP_COLLECTOR_FOR_PERFMONITOR job which is scheduled hourly.
It is executed successfully. But, When I checked the Job Logs , I found something wrong in this. I mention this as below:
"Message text"
Job Started
step 001 started (program RSCOLL00, variant, user ID SHISHYA)
Clean_Plan: Cleanup of DB13 Plannings
Clean_Plan: Started by RSDBPREV on server sarswati
Clean_Plan: Cleaning up jobs of system SD1
Function DB6_PLAN_STOP_BATCH_JOB failed with return code = Job error
Clean_Plan: terminated with error
REASON=Job error
Database system not supported
Job finished
I have checked system time zone in the tcode STZAC which is correct.
So, Please tell me how to resolve this issue.
Thanks & Regards

Error in St04 transaction

Hi Experts, We are getting Exception CX_DBA_ADBC in function unit C_GET_DB_ORA_FILESYSTEM_REQUES ( function group S_ORA_COCKPIT_2 include line 0 ) error in
ST04 > Performance > Wait Event Analysis > Filesystem requests
As a correction we implemented OSS note 1262645 but still the problem persists.
Any advice would be much approeciated.

Getting exception CX_DBA_ADBC while executing ST04

While executing ST04 -> Performance -> Wait Event Analysis -> Filesystem Requests
The following error comes
Exception CX_DBA_ADBC in function unit C_GET_DB_ORA_FILESYSTEM_REQUES ( function group S_ORA_COCKPIT_5 include line 0 )
The database is Oracle.
I have seen SAP NOTE 1262645 under which the correction is delivered in the support pack SAPKB700018 but we already are on that support pack level.
Please suggest.

Hi Sergo
I already checked SM21 & ST22 . There was nothing there.
When i checked alert log there alos i find nothing.
The error description in note 159510 doesnot match our case.
But when i expanded the pop up Exception CX_DBA_ADBC in function unit C_GET_DB_ORA_FILESYSTEM_REQUES and scrolled further, i saw that it is trying to access a table or view that doesnot exist and it gives SQL Message: ORA-00942: table or view does not exist .
The view in question seems to be SAP$KCBFWAIT .
The method to create or replace this table/view is given in the note you mentioned.
I would try to implement it and see if it solves my problem.
Thanks

Performance Problem with several Database accesses

Hello
We have SAP ERP 2004 running on a Oracle DB 9.x and we face a strange behavior of our system. Sometimes it is very slow. MB51 with 1 Material and 1 Month as selection runs into timeout. But i faced the most significant (or strange) problem using SE16 with table bseg. If i use Company code, one item number and year as a selection, it is very fast. If i put in 2 items numbers instead of one, it takes 15 minutes to show the result. This happens everytime i try it.
For me it looks like the system is doing a sequential read instead of using the proper index. This "wrong index" behavior could be the source of many of our performance problems.
Does anybody have a suggestion for me, how to fix this problem?
Thanks in advance
Hans-Peter

As mentioned above you can active trace with ST05 to monitor the problematic SQL request. With the explain function, you will see the estimated cost of the request and the used index.
An other way is during the execution of the request --> ST04 -> performance -> Wait event analysis -> Session monitor
If you use the IN option, your request could be very expensive. And in many cases, the reads can only performed with sequential access.
For an overlook of possible indexes for a table, you can use the DB05. To interpret the results : an index is representative when you have numerous distinct values for a few 'rows per generic keys'
Hope this will help you

Host performance not displayed

Hi,
after installing Additional Management Agent 10.1.0.2 on my servers, performance data for some hosts is not visible (java.lang.NullPointerException in performance overview). Some of the hosts report their performance data, some others do not. All hosts run Windows 2000 Advanced Server SP4, and all are members of the same domain.
Even operating system and hardware information is not available on the host's homepage for one of the server.
Has anyone any idea?
Greetings from Germany, JÃ¶rg.

Dear All,
I have already checked the help file, it is opening properly, and also done to restore the performance assistant by clicking right on the tool bar.
