SAP Note#350011 - To measure CPU performance for BPS applications

Hello,
I am Implementing SAP note 350011 in 2004s BW system (SP13). I have executed the 3 scripts using UPS_BENCHMARK_EXECUTE. But I am not able to get the reference values to compare the result. Please let me know, from where will I be able to get the reference values?

There are alot of waits regarding CPU .I disagree.
The report shows on "CPU + Wait for CPU".
It does NOT separate out the CPU time from "Wait for CPU"
The majority of the time reported could be while on "CPU" with very little doing "Wait for CPU"
enable SQLTRACE=TRUE
tkprof reports both Elapsed Time & CPU Time
the difference between those two values is the real "wait time".

BIA to improve performance for BPS Applications

Hi All,
Is it possible to improve performance of BPS applications using BIA. Currently we are running applications on BI-BPS which because of huge range of period are having a performance issue.
Would request to please share whether in this read and write option of BPS would BIA be helpful and to what extent can the performance be increased?
Request an early reply as system is in really bad shape and users are grappling with poor performance?
Rgds,
Rajeev

Hi Rajeev,
If the performance issue you are facing is while running the query on real-time (transactional) infocube being used in BPS, then BIA can help. The closed requests from real-time cube can be indexed in BIA. At the query runtime, analytic engine reads data from database for open request and from BIA for closed and indexed requests. It combines this data with the plan buffer cache and produce the result.
Hence if you are facing issue with query response time, BIA will defenitely help.

Hi,
You can use Performance Monitor and add the required counters.
Check the below Technet article on Performance Monitor.
http://technet.microsoft.com/en-us/library/cc749249.aspx
Below are the steps to monitor the process in Performance Monitor.
- Go to the Performance Monitor.
- Right-click on the graph and select "Add Counters".
- In the "Available counters" list, open the "Process" section by clicking on the down arrow next to it. Select "% Processor Time" (and any other counter you want).
- In the "Instances of selected object" list, select the process you want to track. Then click on "Add >>" button. Click on OK.

Why all of a sudden I'm getting pop up's stating High CPU performance for plug in, anmd Performance allert, high memory use by firefox, never had these problems till I upgraded to the latesty Firefox offered???????

since I upgraded to the latest version of fire fox, I'm getting pop ups stating, And I quote! Performamce Alert,high memory use by Fire Fox, and High CPU Performance for plug in by Fire fox, never had this problem with the last version of Fire Fox, this has apparently is slowing down mu computer, and I was much better off with the old one

MCW_AA111 System not a valid BW target system for analytical applications

Dear Gurus,
Our project would like to use retail allocation strategy with reference to SAP BW, such as
Quotas based on SAP BW data
Top down (SAP BW)
Bottom up (SAP BW)
To retract the data from BW, we go to the configuration of Data Retraction for Retail/CP. (T-CODE: MCW_AA).
In the Maintenance of Queries for Analytical Applications, we wanted to add a new entry in the query list. We can find the Target Sys. But when we tried the input help(F4) of the Analyt. Appl. Query., the msg: "MCW_AA111:System is not a valid BW target system for analytical applications" prompt out.
RFC connection has already been established between SAP-retail and BW.
Does anybody have any clue?
Thank you.
Alex.

AADSTS50011: The reply address does not match the reply addresses configured for the application

Can anyone tell me where to update the reply address?
I have AD synced from on-prem to Azure, then I setup a website on azurewebsites.net, then created a CNAME record from portal.mydomain.com to portal.azurewebsites.net. When I try to login using portal.mydomain.com I get:
AADSTS50011: The reply address does not match the reply addresses configured for the application.
Can anyone help? Thanks
Frank Russo

Hi Frank69,
Thanks for posting here!
It appears to me that the application is unable to find the URL you have configured on Azure or could be missing from the list. As a result the application is attempting to authenticate against AAD but failing to match the URl it wants.
I would suggest you to re-configure your AAD application on Azure and set one or more reply URLs.

SAP Note 976073 Virsa RTA 5.1 for BASOS 700

Hi all,
Can someone please go through the SAP note 976073 and explain the purpose of activating BC sets ( /VIRSA-CCAUTH_51,/CCCONFIG_51,/CCTAB_51,/RT_51)for compliance calibrator in transaction code SCPR20.
I observed it has something to do with USOBX_C and USOBT_C tables for profile generator but wondering what CC installation and configuration has to do with profile generator.
Thanks in advance !
Samar

CC uses the USOBT tables to determine what Auth Objects (permissions) that a Tcode (action) uses.

SAP Note #723909 Clarification needed: 2G heap for server nodes

We mare upgrading from Enterprise 4.7 to ERP 6.0 SP12. For our ESS/MSS we will use standalone Java NW 7.0 SP14 with XSS SP12. Our portal servers and ERP ABAP are Unix Solaris 9 or 10 64-bit. The portal servers are 4CPU x 16G. We use three server nodes on our central instance and three server nodes on our dialog instance. All server nodes have 2G heap.
Recent load tests indicate we are reaching memory limits in the server nodes. THis causes frequent full GC with tenured objects deleted (very time consuming). We want to increase heap size > 2GB. Note 723909 seems to say this can be done for 64-bit systems, but SAP appears to recommend additional server nodes with 2G heap. I think this is because of GC performance with large heap.
- Are we supported with heap > 2G?
- Are there still concerns with GC when heap > 2G?
- Are there other reasons why heap should be no higher than 2G?
Thanks in advance

- Are we supported with heap > 2G?
- Are there still concerns with GC when heap > 2G?
- Are there other reasons why heap should be no higher than 2G?
You´ve answered your questions yourself
To have a fast J2EE engine you need to absolutely make sure all the heap is covered in physical memory. No swapping should take place at all. Once the system starts swapping in and out, you will loose a lot of performance.
How big is your Oracle SGA? If you can decrase it so all the heaps (+ dispatcher heap) will fit in physical memory you can increase more. We use 2.5 - 3 GB heap (for BI) with three server nodes.

CAPL browser shows that the .can file is write protected while it is not and keeps toggling, CPU performance reach 100%

The problem is when I open the CAPL browser, the CPU load increases to 99~100%, and the .can file I am editing can't be saved, and I keep getting the message "file is protected and can't be saved". This happened on multiple machines with different CANoe versions.
I tested on these versions:
8.0.36
8.0.71
8.0.93
8.1.60
Randomly the icon of the "write protected" appears beside the file name in the file tab inside the CAPL browser, if I could press the save button while it is not appearing the file is saved, other wise I get the error message. The memory usage is also increases too much and then the browser stop responding.
Do any body had the same issue before? any advice?
Operating system: Windows 7 Ultimate 64
AntiVirus installed: McAfee

Hi Allaithy,
Can you clarify how is this issue related to NI CAN products?
Anyway, here are some things to try:
Is this the file on a network? Do you have administrator privileges to this network?
Is file set to Read-only?

Combobox or Dropdown list not working in AIR 2.7 for Mobile Applications

Hey,
I want to use combobox or a dropdown list in my app for Mobile.It is coming properly on the screen.but when I try to select the thing from the list it doesnt gets clicked and the new value is not getting displayed on the dropdown.
Previously I was using older version of AIR.but now am using AIR 2.7.
So is AIR 2.7 creating a problem???
Thanks in advance.
Ronak Shah

ComboBox and DropDownList don't work on mobile devices. It has to do with the differences between touch interfaces and mouse interfaces. You'd have to extend / modify the components a bit and I would recommend creating custom skins optimized for mobile devices.
Or you can just use the ones I already optimized: https://www.flextras.com/index.cfm?event=ProductHome&productID=21

Some problems in measuring system performance

Let's look at thread thread 4, I can see from -L result that thread 4 occupies 3.8% CPU time. But in -mL result shows that thread 4 user part only take 28% time and 72% is waiting for locks.
My question is, is the "waitig for locks" also calculated into CPU load? That's to say, if the 3.8% CPU load includes lock time, is that means the real processing time is 3.8%*28%? or the 3.8% CPU load not includes lock time, So, the 3.8% CPU load is the real cost of this thread (which is 28% user processing). I wish my explanation will not mess you :)
For my colleagues have many arguments on this, but no one could be sure. So I ask the experts here to seek the answers.
many many thanks in advance
Cheers
Shen

#1. The first display you have (without the -m) is not an immediate display. The CPU figures are long-term averages, so they can lie considerably.
Take an otherwise idle machine and run a CPU intensive program. It will take 100% of one CPU immediately, but 'top' and 'prstat' will take many seconds to reflect that.
#2. Whether 'waiting on a lock' takes CPU time probably depends on how it's wating. Solaris has adaptive locks, so sometimes the wait will take CPU time and other times it sleeps. (Going to sleep and waking up again has an overhead associated with it. So if the lock is going to release "quickly", then it makes sense to just spin on the CPU and do nothing for a few cycles until the lock is released. However if it's going to take "a while" for the lock to release, then it's better to release the CPU and let other processes have it while we wait for the lock.)
In most circumstances (and almost certainly in your example) the processes are sleeping while waiting for the lock. However there might be other situations where that is not true.

Implementing SAP Note 386508

Hello Gurus,
May I know how to implement this OSS Note? Will it be done through SNOTE or manually? This is my first time to handle OSS Note implementation. Your help is much highly appreciated..Thanks in advance!

Hi Andrei,
Manual Correction is also a Easy way and cost you very less than SNOTE (Automatic Update).
Just goto the OSSNote (www.service.sap.com) Use your OSS ID to View the note.
Now check the Application Component & Choose that Correction.
In the correction window It is very clear in which Standard Program And in which part you need to delete & replace very clear...
I Feel A Newbie can also do the corrections in SAP Notes Manually.
If it asks for a Acces Key for Correction(change) Then consult your Basis team they will provide you one.
Thanks & regards,
Dileep .C
