Pleasse use a more informative subject in future
The note says:
"An experienced ABAP programmer requires an estimated three to five days to create the ZZ_MB5B work table and these three reports. You can find a similar program as an example in Note 32236: MBMSSQUA.
If you need support during the implementation, contact your SAP consultant."
Are you not an experienced ABAP programmer? If you're not you should pass this on to someone who is experienced. I've read the note, and steps you have to take seem clear to me. Is it the English that's given you problems? What precisely don't you understand?

JRC 2: Performance Problem

Hi.
Our reporting component used JRC 1.x before we upgraded to JRC 2.x. We got two issues after upgrading.
First issue I solved already with a workaround which I published on stackoverflow.com. (1) Does anyone knows where I will find the issue management system to report this issue?
Second issue occurs big performance problem within our project. We opened a report with 6 subreports (which includes 1 upto 3 tables) in 2-4 seconds using JRC 1. If we will open same report using JRC 2, we wait upto 60 seconds.
This methods requires more time with JRC 2 comparing to JRC 1:
ReportClientDocument#open(String, int);
SubreportController#setTableLocation(String, ITable, ITable)
DatabaseController#setTableLocation(ITable, ITable)
Each invocation of one of these methods requires 2-4 seconds.
Thank you in advance.
Best regards
Thomas

hello ....
my report is ''crystal report 11'' => "OLE DB" => "Add Command(select * from table) " .
code(JRC) : eclipse + crystal report for eclipse version 2 => "cr4e-all-in-one-win_2.0.1.zip"

 try {
 String reportName = "report.rpt";
 ReportClientDocument clientDoc = new ReportClientDocument();
 clientDoc.open(reportName, 0);
 String tableAlias = "Command";
 clientDoc.getDatabaseController().setDataSource(myResult("SELECT * FROM table"), tableAlias,tableAlias);
 CrystalReportViewer crystalReportPageViewer = new CrystalReportViewer();
 crystalReportPageViewer.setReportSource(clientDoc.getReportSource());
 crystalReportPageViewer.processHttpRequest(request, response, application, null);
 } catch (ReportSDKExceptionBase e) {

I simplified the code, *myResult("SELECT * FROM table") * is absolutely no problem ,
and this code is absolutely no problem in the "crystal report for eclipse "version 1
but in version 2 run error:

Performance problem in ABAP code

hai guys,
I created report using tables like bsis,t001 etc,( tax report).
I have performance problem in this report.
COuld you pls tell me how to analyse the report and find out the place where process is taking more memory etc.
i did abap trace and runtime analysis..but could not find out exact point.
how to do this..
i want to analysis each subroutine,internal table and query process.
could you pls give me some ideas.

There is an excellent tool available in SAP - Code Inspector.

Transaction is SCII
Try the following link and I am sure you will find a bunch of useful documents.
<a href="http://www.google.co.in/search?hl=en&safe=off&q=site%3Asdn.sap.comfiletype%3ApdfCode+Inspector&btnG=Search&meta=">ABAP Performance</a>
I use the Code Inspector to search for
a) All the select statements which are present within the loop
b) Nested Loops
c) Select query without providing criteria for primary keys, depending upon situation
d) Can the search be narrowed with extra conditions
e) Using READ .. BINARY SEARCH if internal table has lots of records.
The list is actually endless, but this is something to start with.
You can actually have a checklist, and depending upon it, go through your code. The more you adhere to checklist, you will find that, the performance would dramatically improve.
Also use ST05 transaction, for SQL Trace and find out which select query is taking the maximum time for response.

Hi,
I have analysed your program and i would like to share following points for better performance of this report :
(a) Use the field Names instead of Select * or Select Single * as if you use the field names it will consume less amount of resources inside the loop as well as you have lot many Select Single * and u r using very big tables like VBAP and many more.
(b) Trace on ST05 which particular query is mostly effecting your system or use ST12 in current mode to trace for less inputs which run the report for 20-30 min so that we get an idea which queries are effecting the system and taking a lot of time.
(c) In Case of internal tables sort the data properly and use binary search for getting the data.
I think this will help.
Thanks and Regards,
Harsh

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers
Ben

Performance problems with abap report SAPLPRGN_STRUCTURE during users login

Hello,
after patchimport of SAP BASIS level 21 and SAPABAP level 21 our SAP Production System (ECC6-UNICODE KERNEL 240) denote a performance problems. A lot of ours users during logon phase must wait until 10-12 minutes before that the navigation menu is displayed. The problem is generated by the slow performance of the standard SAP REPORT SAPLPRGN_STRUCTURE that require a lot time. Any idea?
Thanks

Hi Pat,
I would stop SAP and use DLTR3PKG, If this doesn't help, you need to investigate, if it is a CPU or DB-Time issue in ST03. Then you have to handle accordingly ...

Performance problems with SAP GUI 7.10 and BEx 3.5 Patch 400?

Hi everybody,
we installed SAP GUI 7.10 and BEx 3.5 Patch 400 and detected hugh performance problems with this version in comparison to the SAP GUI 6.40 and BEx 3.5 or BEx 7.0 Patch 800.
Does anybody detect the same problems?
Best regards,
Ulli

Most important question when you are talking about performance-issues:
which OC are you working on and which excel version?

Performance problems with EP 6 and MS IE

Hi everybody,
since a couple of days, we are facing a sever performance problem with our SAP EP 6.0. When I access the system with MS Internet Explorer 6.0, it takes 5-10 minutes after the Login. With Firefox Browser, the performance is ok. Therefore I assume that it must be a problem with the IE settings. Does anybody know a solution?
Best regards,
Michael

There are a few things that this could be. I've seen the setting "Empty Temporary Internet Files folder when browser is closed" cause a lot of performance problems (This is in the advanced settings in your IE).
This will cause your cache to be cleared out each time the browser is closed and cause a lot more data to be downloaded each time you login to the system.
For more analysis I'd recommend putting a tool like HTTPWatch into your IE browser and seeing which requests are using the most time.

Performance problems with DFSN, ABE and SMB

Hello,
We have identified a problem with DFS-Namespace (DFSN), Access Based Enumeration (ABE) and SMB File Service.
Currently we have two Windows Server 2008 R2 servers providing the domain-based DFSN in functional level Windows Server 2008 R2 with activated ABE.
The DFSN servers have the most current hotfixes for DFSN and SMB installed, according to http://support.microsoft.com/kb/968429/en-us and http://support.microsoft.com/kb/2473205/en-us
We have only one AD-site and don't use DFS-Replication.
Servers have 2 Intel X5550 4 Core CPUs and 32 GB Ram.
Network is a LAN.
Our DFSN looks like this:
\\contoso.com\home
   Contains 10.000 Links
   Drive mapping on clients to subfolder \\contoso.com\home\username
\\contoso.com\group
   Contains 2500 Links
   Drive mapping on clients directly to \\contoso.com\group
On \\contoso.com\group we serve different folders for teams, projects and other groups with different access permissions based on AD groups.
We have to use ABE, so that users see only accessible Links (folders)
We encounter sometimes multiple times a day enterprise-wide performance problems for 30 seconds when accessing our Namespaces.
After six weeks of researching and analyzing we were able to identify the exact problem.
Administrators create a new DFS-Link in our Namespace \\contoso.com\group with correct permissions using the following command line:
dfsutil.exe link \\contoso.com\group\project123 \\fileserver1\share\project123
dfsutil.exe property sd grant \\contoso.com\group\project123 CONTOSO\group-project123:RX protect replace
This is done a few times a day.
There is no possibility to create the folder and set the permissions in one step.
DFSN process on our DFSN-servers create the new link and the corresponding folder in C:\DFSRoots.
At this time, we have for example 2000+ clients having an active session to the root of the namespace \\contoso.com\group.
Active session means a Windows Explorer opened to the mapped drive or to any subfolder.
The file server process (Lanmanserver) sends a change notification (SMB-Protocol) to each client with an active session \\contoso.com\group.
All the clients which were getting the notification now start to refresh the folder listing of \\contoso.com\group
This was identified by an network trace on our DFSN-servers and different clients.
Due to ABE the servers have to compute the folder listing for each request.
DFS-Service on the servers doen't respond for propably 30 seconds to any additional requests. CPU usage increases significantly over this period and went back to normal afterwards. On our hardware from about 5% to 50%.
Users can't access all DFS-Namespaces during this time and applications using data from DFS-Namespace stop responding.
Side effect: Windows reports on clients a slow-link detection for \\contoso.com\home, which can be offline available for users (described here for WAN-connections: http://blogs.technet.com/b/askds/archive/2011/12/14/slow-link-with-windows-7-and-dfs-namespaces.aspx)
Problem doesn't occure when creating a link in \\contoso.com\home, because users have only a mapping to subfolders.
Currently, the problem doesn't occure also for \\contoso.com\app, because users usually don't use Windows Explorer accessing this mapping.
Disabling ABE reduces the DFSN freeze time, but doesn't solve the problem.
Problem also occurs with Windows Server 2012 R2 as DFSN-server.
There is a registry key available for clients to avoid the reponse to the change notification (NoRemoteChangeNotify, see http://support.microsoft.com/kb/812669/en-us)
This might fix the problem with DFSN, but results in other problems for the users. For example, they have to press F5 for refreshing every remote directory on change.
Is there a possibility to disable the SMB change notification on server side ?
TIA and regards,
Ralf Gaudes

Performance problems with File Adapter and XI freeze

Hi NetWeaver XI geeks,
We are deploying a XI based product and encounter some huge performance problems. Here after the scenario and the issues:
- NetWeaver XI 2004
- SAP 4.6c
- Outbound Channel
- No mapping used and only the iDocs Adapter is involved in the pipeline processing
- File Adapter
- message file size < 2Ko
We have zeroed down the problem to Idoc adapters performance.
We are using a file channel and every 15 seconds a file in a valid Idoc format is placed in a folder, Idoc adapter picks up the file from this folder and sends it to the SAP R/3 instance.
For few minutes (approx 5 mins) it works (the CPU usage is less then 20% even if processing time seems huge : 5sec/msg) but after this time the application gets blocked and the CPU gets overloaded at 100% (2 processes disp_worker.exe at 50% each).
If we inject several files in the source folder at the same time or if we decrease the time gap (from 15 seconds to 10 seconds) between creation of 2 Idoc files , the process blocks after posting 2-3 docs to SAP R/3.
Could you point us some reasons that could provoke that behavior?
Basically looking for some help in improving performance of the Idoc adapter.
Thanks in advance for your help and regards,
Adalbert

Hi Bhavesh,
Thanks for your suggestions. We will test...
We wonder if the hardware is not the problem of this extremely poor performance.
Our XI server is:
 Windows 2003 Server
 Processors: 2x3GHZ
 RAM: 4GB (the memory do not soak)
The messages are well formed iDocs = single line INVOICES.
Some posts are talking 2000 messages processed in some seconds... whereas we got 5 sec per message.
Tnanks for your help.

IPad 1 email and performance problems ios5

Since I upgraded my iPad 1(wifi only) to iOS 5' I have been having numerous performance problems, and my email continuously sys "checking Email". I have tried restarting my iPod ith no luck. Deleting d reading the accounts woks briefly, but after 15-20 minutes the email problem ones back. The update has relly crippled my iPad.
Has anyone else had this problem? Any ideas to resolve it?
Regards,
Jason

While Downgrading is not actually supported by Apple I found a video on You Type that walked me through it. Just do a search on You tube and you will find it. The one I used was by lizards821. His videos cover any errors you might have.
Once I reverted, I then did a restore from the backup I made when upgrading to IOS 5 and all of my apps were restored while keeping my downgraded IOS.
Good Luck, it was well worth it for me. I have the stable IPAD I love so much back again.

6321 performance problems

Hello again,
we are experiencing performance problems with the 6321 in our environment - 10 kHz system clock, i.e. the analog input channels should be read in every 100 µs. This works fine with one card (differentially cabled), but if we plug a second card the systems just comes to a grinding halt.
It appears, that one AI channel register access is taking us about 4 µs, which would mean 64 µs using 16 channels. We have tried RLP, "pure" DMA and DMA using interrupts.
Am I getting something wrong or was the 6321 just not designed for this kind of application?
Best regards,
Philip

(new?) performance problem using jDriver after a Sql Server 6.5 to 2000 conversion

Hi,
This is similar - yet different - to a few of the old postings about performance
problems with using jdbc drivers against Sql Server 7 & 2000.
Here's the situation:
I am running a standalone java application on a Solaris box using BEA's jdbc driver
to connect to a Sql Server database on another network. The application retrieves
data from the database through joins on several tables for approximately 40,000
unique ids. It then processes all of this data and produces a file. We tuned
the app so that the execution time for a single run through the application was
24 minutes running against Sql Server 6.5 with BEA's jdbc driver. After performing
a DBMS conversion to upgrade it to Sql Server 2000 I switched the jDriver to the
Sql Server 2000 version. I ran the app and got an alarming execution time of
5hrs 32 min. After some research, I found the problem with unicode and nvarchar/varchar
and set the "useVarChars" property to "true" on the driver. The execution time
for a single run through the application is now 56 minutes.
56 minutes compared to 5 1/2 hrs is an amazing improvement. However, it is still
over twice the execution time that I was seeing against the 6.5 database. Theoretically,
I should be able to switch out my jdbc driver and the DBMS conversion should be
invisible to my application. That would also mean that I should be seeing the
same execution times with both versions of the DBMS. Has anybody else seen a
simlar situation? Are there any other settings or fixes that I can put into place
to get my performance back down to what I was seeing with 6.5? I would rather
not have to go through and perform another round of performance tuning after having
already done this when the app was originally built.
thanks,
mike

Joe,
This was actually my next step. I replaced the BEA driver with
the MS driver and let it run through with out making any
configuration changes, just to see what happened. I got an
execution time of about 7 1/2 hrs (which was shocking). So,
(comparing apples to apples) while leaving the default unicode
property on, BEA ran faster than MS, 5 1/2 hrs to 7 1/2 hrs.
I then set the 'SendStringParametersAsUnicode' to 'false' on the
MS driver and ran another test. This time the application
executed in just over 24 minutes. The actual runtime was 24 min
16 sec, which is still ever so slightly above the actual runtime
against SS 6.5 which was 23 min 35 sec, but is twice as fast as the
56 minutes that BEA's driver was giving me.
I think that this is very interesting. I checked to make sure that
there were no outside factors that may have been influencing the
runtimes in either case, and there were none. Just to make sure,
I ran each driver again and got the same results. It sounds like
there are no known issues regarding this?
We have people looking into things on the DBMS side and I'm still
looking into things on my end, but so far none of us have found
anything. We'd like to continue using BEA's driver for the
support and the fact that we use Weblogic Server for all of our
online applications, but this new data might mean that I have to
switch drivers for this particular application.Thanks. No, there is no known issue, and if you put a packet sniffer
between the client and DBMS, you will probably not see any appreciable
difference in the content of the SQL sent be either driver. My suspicion is
that it involves the historical backward compatibility built in to the DBMS.
It must still handle several iterations of older applications, speaking obsolete
versions of the DBMS protocol, and expecting different DBMS behavior!
Our driver presents itself as a SQL7-level application, and may well be treated
differently than a newer one. This may include different query processing.
Because our driver is deprecated, it is unlikely that it will be changed in
future. We will certainly support you using the MS driver, and if you look
in the MS JDBC newsgroup, you'll see more answers from BEA folks than
from MS people!
Joe

The next test you should do, to isolate the issue, is to try another
JDBC driver.
MS provides a type-4 driver now, for free. If it is significantly faster,
it would be
interesting. However, it would still not isolate the problem, because
we still would
need to know what query plan is created by the DBMS, and why.
Joe Weinstein at BEA
PS: I can only tell you that our driver has not changed in it's semantic
function.
It essentially send SQL to the DBMS. It doesn't alter it.

How to find cause of db performance problem??

Hi,
I am facing continuous performance issues with our database and for that I want to know how I can get information about the following points:
1- How to find most accessed table(s) or tables with highest hits or top queries is accessing which table(s)?
2- What indication can tell that a particular table need to be rebuilt?
3- When to rebuild indexes? and how to know that an indexed need to be rebuilt?
Your prompt reply is highly appreciated
Thanks,
Younis

Hi,
a good starting point for investigating poor database performance is AWR (if you have a license for that) or statspack (if you don't). If you need help interpreting it, you can refer to J. Lewis's series on statspack reports (also applies to AWR):
http://jonathanlewis.wordpress.com/2011/03/09/statspack-reports/
I have also made a few blog posts on this topic, see http://savvinov.com/tag/awr/
Regarding your other questions -- countrary to popular belief, rebuilding indexes or tables is seldom helpful. More often, performance problems are caused by bad execution plans (side effects of bind peaking, inaccurate statistics, correlated predicates etc.), data design issues, bad coding practices, not using bind variables etc.
Database performance topic is a huge topic and obviously cannot fit into a discussion thread. Christian Antognini's book "Oracle Performance Troubleshooting" can provide you a gentle introduction into performance tuning, provided you already have good familiarity with Oracle architecture.
Or, if you want help with your particular problem, post your AWR report here and briefly describe what your users are unhappy about -- there is a good chance that you get valuable feedback from several renowned experts.
Good luck!
Best regards,
Nikolay
