STWB_WORK - Bad Performance
Hello Experts,
we run Solution Manager 7.0 EHP1 (70108).
For some time now we have the problem, that the opening of test-packages in the stwb_work takes a lot of time. By clicking a package, the time will lost in "Formatting Message Display". The same happens, if the test-package is opened and I click on Message-Overview.
The blueprint of the choosen project is small. There ar only 20 Messages in this test-package.
We have analysed this behavior (SAP Workload: Single Records) and there are the following parameters:
STWB_WORK RSTWB_ANALYZE
19.555 Response time (ms)
18.376 Time in WPs (ms)
403 Wait time (ms)
14.250 CPU time (ms)
2.316 DB req. time (ms)
Detail: Response Time 19.555 ms
Wait for work process 403 ms
Processing time 15.734 ms
Load Time 134 ms
Generating time 0 ms
Roll (in+wait) time 962 ms
Database request time 2.316 ms
Enqueue time 7 ms
Database requests 2.316 ms
Database rows 28.954 total
Requests 48.804 total
Database calls 6.974
So it seems the time is lost by CPU activities.
I searched for notes and found the following:
- Link: [1086478|https://websmp130.sap-ag.de/sap(bD1kZSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1086478] (not implementable, contained in 70105)

Have anyone an idea what I can do?
Thanks for help!

Hi Guys,
As per the message Jens opened, he mentioned the message created by
Christoph, so I checked the information. As it is useful for everyone here
I'm updating the thread with it so everyone could access it.
I discussed directly with the developer responsible for this. They have
delivered some improvements with the SP08 and they're working on and
plaining some more improvements for this. The problem is that this
requires a huge amount of time and efforts to be changed due to it's
complexity. They plan to deliver some more improvements with NW 7.02
SP12 but it could be delayed a little bit more depending on the problems
that could be faced in the process.
I hope this help to solve your doubts. I understand your concerns on
this, regarding the performance, but complementing what Christoph
already said in the thread, this area has to perform a huge number of
code operations and many access to informations to gather and organize
the messages information. So I hope you understand why this requires so
much time and efforts to be improved.
Kind regards,
Fabricius

CMP 6.1 Entity bad performance.
I'am using entity 1.1 EJB on WL 6.1 and facing very bad performances:
around 150ms for an insert (i have 20 columns).
When accessing an order interface to read 2 fields in a session bean method: around
90 ms.
I'am very disapointed and confused. What should I look up for
to increase the performance ? Any important tuning or parameters ? Should I use EJB
2.0 to have significant perf ?
Thanks for any advice because we are thinking to switch all the application on stored
procedures. A solution without Entity and fewer stateless session beans.
My config:
WL: 6.1 on Sun sparc
SGBD: Sybase
Entity: WebLogic 6.0.0 EJB 1.1 RDBMS (weblogic-rdbms11-persistence-600.dtd)
ThanksHistorically its hard to get good performance & scalability out of sybase
without using stored procs. Using dynamic sql on sybase just doesnt do as
well as procs. Oracle on the other hand can get very close to stored proc
speed out of well written dynamic sql.
As far as weblogic goes, my experience is the focus of their testing for db
related stuff is Oracle, then DB2, then MSSQLServer. Sybase is usually last
on the list.
As far as the 6.1 cmp, haven't used it much, but because of these other
things I would be cautious about using it with Sybase.

Bad performance when open a bi publisher report in excel
We use bi publisher(xml publisher) to create a customized report. For a small report, user like it very much. But for a bigger report, users complain about the performance when they open the file.
I know it is not a native excel file, that may cause the bad performance. So I ask my user to save it to a new file as a native excel format. The new file still worse than a normal excel file when we open it.
I did a test. We try to save a bi publish report to excel format, the size shrink to 4Mb. But if we "copy all" and "Paste Special" value only to a new excel file, the size is only 1Mb.
Do I have any way to improve that, users are complaining everyday. Thanks!
I did a test today.
I create a test report
Test 1: Original file from BIP in EBS is 10Mb. We save it in my local disk, when we open the file, it takes 43 sec.
Test 2: We save the file in native excel format, the file size is 2.28Mb, it takes 7 sec. to open.
Test 3: We copy all cell and "PasteSpecial" to a new excel file with value only. The file size is 1.66Mb, it takes only 1 sec to open.
Edited by: Rex Lin on 2010/3/31 下午 11:26EBS or Standalone BIP?
If EBS see this thread for suggestions on performance tuning and hints and tips:

Note also that I did end up rewriting my report as PL/SQL producing a csv file and have done with several large reports in BIP on EBS.

Bad performance updating purchase order (ME22N)
Hello!
Recently, we face bad performance updating purchase orders using transaction ME22N. The problem occurs since we implemented change documents for a custom table T. T is used to store additional data to purchase order positions using BAdIs ME_PROCESS_PO_CUST and ME_GUI_PO_CUST.
I've created a change document C_T for T using transaction SCDO. The update module of the change document is triggered in the method POST of BAdI ME_PROCESS_PO_CUST.
Checking transaction SM13, I recognized that the update requests of ME22n have status INIT for several minutes before they are processed. I also tried to exclude the call of the update module for change document C_T (in Method POST) - the performance problem still occurs!
The problem only occurs with transaction ME22N, thus I assume that the reason is the new change document C_T.
Thanks for your help!
Greetings,
WolfgangI agree with vikram, we don't have enough information, even not a small hint on usage of this field, so which answer do you expect (The quality of an answer depends ...) This analysis must be executed on your system...
From a technical point of view, the BAPI_PO_CHANGE has EXTENSIONIN table parameter, fill it using structure BAPI_TE_MEPOITEM[X] alreading containing CI_EKPODB (*) and CI_EKPODBX (**)

Raymond
(*) I guess you have used this include
(**) I guess you forgot this one (same field names but data element always BAPIUPDATE) -
Reporting on master data customer and bad performances : any workaround ?
Hello,
I've been asked to investiguate on bad performances encountered when performing reporting
on the specific master data zcustomer.
Basically this master data has a quite similar design that 0customer, there are 96000 entries in the master data table.
A simple query has been developed : the reporting is done on the master data zcustomer and its attributes : no key figure, no calculation, no restriction ...
Nevertheless, the query can not be executed .. the query runs around 10 minute in rsrt, then the private memory is exhausted and then a short dump is generated.
I tried to buid a very simple query on 0customer, this time, without the attributes ... and it took more than 30 sec before I get the results.
I checked the queries statistics :
3.x Analyzer Server 10 sec
OLAP: Read Texts : 20 sec
How is it that it is so long to performthe reporitng on those master data, while in the same time If i try to display the content in SAP by choosing "maintain master data", I have an immediate answer.
I there any workaround ?
Any help would be really appreciated.
thank you.
RaoulHi.
How much data have you got in the cube?
If you make no restrictions, you are asking the system to return data for all 96.000 customers. That is one thing that might take some time.
Also, using the attributes of this customer object, fx making selection or displaying several of them, means that the system has to run through the 96.000 records in masterdata to know what goes where in the report.
When you display the masterdata, you are by default displaying just the 250 or so first hits, and you are not joining against any cube or sorting the result set, so that is fast.
You should make some kind of restriction on other things than zcustomer (time, org.unit, version, etc, to limit the dataset from the cube, but also a restriction on one of the zcustomer attribs, with an index for that maybe, and performance should improve.

THNKSHi Josue,
The bad performance is because you're not specifying the primary keys of the table BKPF in your WHERE condition; BKPF usually is a big table.
What you really need is to create a new index on database for table BKPF via the ABAP Dictionary on fields BUKRS, AWKEY, GJAHR & BSTAT. You'll find the performace of the program will significantly increase after the new index is activated. But I would talk to the Basis first to confirm they have no issues if you create a new index for BKPF on the database system.
Hope this helps.

Bad performance in web intelligence reports
Hi,
We use Business Objects with Web Intelligence documents and Crystal Reports.
We are supporting bad performance when we use the reports specilly when we need to change the drill options
Can someone telling me if exists some best practices to improve performance? What features should i look to?
Best Regards
João FernandesHi,
Thank you for your interest. I know that this a issue with many variables because that i need information about anything that could cause bad performance.
For bad performance i mean the time that we take running and refreshing reports data.
We have reports with many lines but the performance is bad even when a few users are in the system
Best Regards

Help: Bad performance in marketing documents!
Hello,
When creating an AR delivery note which has about 10 lines, we have really noticed that the creation of lines becomes slower and slower. This especially happens when making tab in the system field "Quantity". In fact, before going to the next field quickly, it stays in Quantity field for about 5 seconds!
The number of formatted searches in AR delivery note is only 5. And only one is automatic. The number of user fields is about 5.
We have heard about the bad performance when the number of lines increases in the documents when having formatted searches, but it is odd to happen this with about 10 lines in the document.
We are using PL16 and this issue seems to have been solved already at PL10.
Could you throw some light on this?
Thanks in advance,It is solved now.
It had to be with the automatic formated search in 2 head fields.
If the automatic search is removed, the performance is OK.
Hope it helps you, -
Bad performance on system, export/import buffer many sawps
Hello,
I have an ECC 6.0 system on AIX with 6 application servers. There seems to be a performance problem on the system, this issue is being noticed very well when people are trying to save a sale order for example, this operation takes about 10 minutes.
Sometimes we get short dumps TSV_TNEW_PAGE_ALLOC_FAILED or MEMORY_NO_MORE_PAGING but not very often.
I am not very good at studying the performance issues, but from what I could see is that there are may swaps on buffer export/import, program and generic key. Also the HitRatio is 88% at buffer export/import, which I think is pretty low.
I know that the maximum value accepted of swaps per day is 10000, is that right?
Can you please advice me what needs to be done in order for these swaps to decrese and hit ratio to increase? And also what else I should do in order to analyse and root cause and the bad performance of the system?
Many thannks,
manolivHi,
sappfpar determines the minimum and maximum (worst-case) swap space requirements of an R/3 application server. It also checks on shared memory requirements and that the em/initial_size_MB and abap/heap_area_total parameters are correctly set with the following procedure:
/usr/sap/<SYSTEMNAME>/SYS/exe/run/sappfpar check pf=/usr/sap/<SYSTMENAME>/SYS/profile/<Profile name>
At the end of the list, the program reports the minimum swap space, maximum heap space, and worst case swap space requirements:
Additional Swap Space Requirements :
You will probably need to increase the size of the swap space in hosts in which R/3 application servers run.
As a rule of thumb, swap space should equal
3 x Size of Main Storage or at least 1 GB, whichever is larger.
SAP recommends a swap space of 2-3 GB for optimal performance.
Determining Current Swap Space Availability: memlimits
You can find out how much swap space is currently available in your host system with R/3s memlimits program.
Heres how to run memlimits:
From the UNIX command prompt, run the R/3 memlimits program to check on the size of the available swap space on the host system on which an R/3 application server is to run.
The application server must be stopped, not running.
/usr/sap/<SYSTEMNAME>/SYS/exe/run/memlimits | more
The available swap space is reported in the output line Total available swap space: at the end of the program output. The program also indicates whether this amount of swap space will be adequate and determines the size of the data segments in the system. -
Bad performance when deleting report column in webi(with "Design – Structure only")
Hi all,
One of our customer has recently upgraded from BO XI to BO4.1. In the new BO 4.1, they encountered a bad performance issue when they were deleting a column in Webi(using "Design – Structure only" mode).
With “Design – Structure only" mode, it took webi about 10 seconds to complete after the customer right-clicked a report column and clicked the "delete". The customer said that they only need to wait for less than 1 second when they did the same in BO XI old version.
The new BO version used is 4.1SP02, installed in Windows Server 2008 R2. (Server with 32 core CPU, 32G memory)
This bad performance happened in both Webi web and Rich Client. (in Webi Rich Client, the performance is a little bit better. The 'delete column' action takes about 8 seconds to complete).
Do anyone know how to tune this performance in webi? Thank you.
Besides, it seems that each time we are making change in the webi report structure in IE or Rich Client, webi need to interact with Server site to upload the changes. Is there any option to change this behavior? Say, do not upload change to Server for when 'deleting report column', only trigger the upload after a set of actions(e.g. trigger when click the "Save" button).
Thank you.
Regards,
Eton.Hi all,
Could anyone help me on this? Thanks!
What customer concerns now is that when they did the same 'column editing' action in BO XI R2 for the same report, they did not need to wait. And they need to wait for at least 7-8 second in the BO 4.1SP02 environment for this action to complete.(data already purged, in structure-only mode)
One more information about the webi report being editing is: there are many sheets in the report(about 6~10 sheets in one report). Customer don't want to separate these sheet into different reports as it will increase the effort of their end users to locate similar report sheets.

Eton. -
Temporary LOBs - bad performance when nocache is used
Hello.
Please, advise me what could be the reason of bad performance row 8 from the next anonymous block:
declare
i integer;
c clob := 'c';
procedure LTrimSys(InCLOB in clob ) is
OutCLOB clob;
begin
DBMS_LOB.CREATETEMPORARY(OutCLOB, false, DBMS_LOB.call);
dbms_lob.Copy(OutCLOB, InCLOB, dbms_lob.getlength(InCLOB));
DBMS_LOB.freetemporary(OutCLOB);
end;
begin
for j in 1 .. 1000 loop
LTrimSys(c);
end loop;
end;
I have two practically identical databases 10.2.0.4.0 EE 64-bit on Windows
On first DB I have elapsed time: 4 sec, on second - 0.2 sec
I didn't find important difference between init parameters (hidden parameters too).
First DB has more memory (PGA) then second.
Main time events in time of executing anonymous block on first DB are
PL/SQL execution elapsed time
DB CPU
sql execute elapsed time
DB time
In second DB - the same but much less
If I use caching of temporary LOBs then both DBs work fine, but I can not understand why first DB works slowly when I use nocache temporary LOBs.
What can be the reason?I don't think that is the problem. See next outputs:

How to solve bad performance in vi server
I'm useing vi server in a recursively programming structure in labview 7.1.
I have very bad performance result so i made a test comparing the speed of che various vi server call and the native.
my tests are:
normal calling.
vi server calling by reference node
vi server calling by invoke node
for each vi server calling type i tried:
unique reference calling
different reference calling
different reference, preloaded, calling
the only 1 case i found a loosing of performace acceptable 24% respect the normal calling: vi server calling by reference node with unique reference.
unfortunately this kind of calling is able to catch come kind of recunsion an forbidden it and this calling wait all the time the end of the execution of the vi called.
All the oter kinds of caling have very bad performance: from 90% to 99,9% LESS then the normal calling (10 to 1000 times more in execution time).
In addition there is a prblem in invoke colling: if you execute a invoke node with wait until done true, the mouse pointer fliks with the busy icone. that heppens in all the possible configuration.
I would like ti know if someuone as some solution to this performance problem and if Labview 8.0 fixs this problems.
Best regarda.
ing. Luca BenvegnùHi Luca,
I've made some researches for you and, what can I say is that there is a certain number of requests about "vi server performances". There are some things that are in general suggested in this situation:
1) Be "minimalist" about the use of images, graph,... And avoid Large data structures: wiring large structures into/out-of sub-VI's can take time: pass the smallest amount of data.
2) Avoid repeated calls. Calling the sub-VI's frequently, in a loop for example, create a call over-head that could be an issue. For the same reason put the "wait until" function with a specification of time in order to run loops only as often as strictly required.
However, about your question of fixing the problem with LabVIEW 8.0, I suggest you to download the Evaluation Version of LabVIEW 8.2 and try by yourself if performances are better.
I hope I've been of some help.

Sun Ray @ home - VPN bad performance
Hi All
we've setup a test configuration with a Sun Ray Server (dedicated network) a CISCO PIX 501 and one DTU SR2.
The screen refresh performance on the DTU is very bad. Other DTUs, connected directly to the SRSS are fine.
We've played around with the bandwith limit on the SR2 (GUI firmware):
no limit: DTU unusable
3000: DTU slow
1500: DTU more slower
700: unusable
The throughput of the PIX 501 should be around 3MPS. The PIX does nothing else than serving one DTU. All components (SR Server, PIX, DTU) are in the same room and connected directly to each other
Is the small PIX the reason for the bad performance ?
Should it work smoothly with only one DTU?
Which Hardware (vpn box) is recommended to serve at least 10 SR2 DTUs ?
Thanks a lot.

CarstenYou problem could be fragmentation. Have you lowered the default MTU (1500). MTU of 1356 works with my ASA 5505. Here is a nice article on the subject, http://blogs.sun.com/ThinkThin/entry/the_importance_of_mtu .

Master column tree - bad performance
Hello,
I have a table with master column that uses recursive node without Load Children event. the whole table loads at startup. I Have very bad performance : every click on the little triangle takes about 6-7 seconds, and there is even no round-trip to server because all data is already at the client!
I need to show list of products by there family (50 families, each has 10 products). How can i imporve my performance (maybe server configuration or my code or another method)
I work with ep 7 sp12.
Thanks
Roni.Hi Roni,
Yes, you have to manipulate the add element on before loading the tree. Best Practice is to use onLoadChildren event. Loading the tree at once will always have performance issues.
Refer to these tutorial for creating tree using onLoadChildren event.
