Performance Problems on Faces Navigation Diagram and Hyperthreading query
Am I the only one having performance problems when dealing with Faces-Config Diagrams of about 35 JSPs displayed on the sheet. using Jdev 10.1.3 It's taking my workstation about a full minute and a half to update the name of an arrow. The most stressed component during this task seems to be the CPU.
And just another question has anybody investigated how is the performance of Jdev affected by either enabling or disabling hyperthreading? In my case my CPU usage manages to reach only 50%. I'm tempted to switch HT off to let JDev use all the cpu power. if that would be the case.
Hello Diego,
you mentioned that you compared a BEx Query with the Web INtelligence report. Could you provide more details here ?
- what are the elements in the rows, columns and free characterisitcs in the BEx Query ?
- was the query execute as designed in the BEx Query Designer with BEx Web Reporting ?
- what are the elements in the WebIntelligence Query panel ?
thanks
Ingo

Navigation block and the Query Table Side by side in output
Hi
I am unable to get the navigation block and the query table side by side when i execute the WAD .Is it possible to place those 2 objects next to each other in the WAD output.In the WAD design those 2 are placed side by side.
Regards,PraI meant Html Table:
In WAD in menu you can choose Insert -> Table -> Insert Table
You need 1 row, 2 columns. In one of the column you should put navigation block and in the other table.
Regards

Performance Problems with "For all Entries" and a big internal table
We have big Performance Problems with following Statement:
SELECT * FROM zeedmt_zmon INTO TABLE gt_zmon_help
FOR ALL ENTRIES IN gt_zmon_help
WHERE
status = 'IAI200' AND
logdat IN gs_dat AND
ztrack = gt_zmon_help-ztrack.
In the internal table gt_zmon_help are over 1000000 entries.
Anyone an Idea how to improve the Performance?
Thank you!>

You can't expect miracles. With over a million entries in your itab any select is going to take a bit of time. Do you really need all these records in the itab? How many records is the select bringing back? I'm assuming that you have got and are using indexes on your ZEEDMT_ZMON table.
In this situation, I'd first of all try to think of another way of running the query and restricting the amount of data, but if this were not possible I'd just run it in the background and accept that it is going to take a long time. -
Performance problem between Oracle.DataAccess v1 and v2
Hi, I have serious performance problem with OracleDataReader when I use the GetValues method.
My server is Oracle 9.2.0.7, and i use ODAC v10.2.0.221
I create a dummy table for benchmark :
create table test (a varchar2(50), b number)
begin
for i in 1..62359 loop
insert into test values ('Values ' || i, i);
end loop;
commit;
end;
I use the same code for benchmark Framework v1 and Framework v2.
Code :
try {
OracleConnection c = new OracleConnection("user id=saturne_dbo;password=***;data source=satedfx;");
c.Open();
go(c);
c.Close();
catch (Exception ex) {
MessageBox.Show(ex.Message);
private void go(IDbConnection c) {
IDbCommand cmd = c.CreateCommand();
cmd.CommandText = "select * from test";
cmd.CommandType = CommandType.Text;
DateTime dt = DateTime.Now;
IDataReader reader = cmd.ExecuteReader();
int count = 0;
while (reader.Read()) {
object[] fields = new object[reader.FieldCount];
reader.GetValues(fields);
count++;
reader.Close();
TimeSpan eps = DateTime.Now - dt;
MessageBox.Show("Time " + count + " : " + eps.TotalSeconds);
Result are :
Framework v1 with OracleDataAccess 1.10.2.2.20 "Time 62359 : 0.5"
Framework v2 with OracleDataAccess 2.10.2.2.20 "Time 62359 : 3.57" FACTOR 6 !!!!!
I notice same problem with oleDb provider and Microsoft Oracle Client provider..
It's a serious problem for my production server, the time calculation explode...
Where is the explication ?
Do u know solution ?Can you please try out following -
1. Create a .NET 1.x DLL with your benchmark code. This will obviously use ODP.NET for .NET 1.x.
2. Call this assembly routine from a .NET 1.x executable and note the results.
3. Now call this assembly routine from a .NET 2.0 executable and note the results.
The idea is to always use "ODP.NET for .NET 1.x" even in .NET 2.0 runtime. This will tell us whether the performance degradation is a runtime issue. -
Query performance problem - events 2505-read cache and 2510-write cache
Hi,
I am experiencing severe performance problems with a query, specifically with events 2505 (Read Cache) and 2510 (Write Cache) which went up to 11000 seconds on some executions. Data Manager (400 s), OLAP data selection (90 s) and OLAP user exit (250 s) are other the other event with noticeable times. All other events are very quick.
The query settings (RSRT) are
persistent cache across each app server -> cluster table,
update cache in delta process is checked ->group on infoprovider type
use cache despite virtual characteristics/key figs checked (one info-cube has1 virtual key figure which should have a static result for a day)
=>Do you know how I can get more details than what's in 0TCT_C02 to break down the read and write cache events time or do you have any recommandation?
I have checked and no dataloads were in progres on the info-providers and no master data loads (change run). Overall system performance was acceptable for other queries.

Performance problem with Integration with COGNOS and Bex
Hi Gems
I have a performance problem with some of my queries when integrating with the COGNOS
My query is simple which gets the data for the date interval : "
From Date: 20070101
To date:20070829
When executing the query in the Bex it takes 2mins but when it is executed in the COGNOS it takes almost 10mins and above..
Any where can we debug the report how the data is sending to the cognos. Like debugging the OLEDB ..
and how to increase the performance.. of the query in the Cognos ..
Thanks in Advance

AKHi,
Please check the following CA Unicenter config files on the SunMC server:
- is the Event Adapter (ea-start) running ?, without these daemon no event forwarding is done the CA Unicenter nor discover from Ca unicenter is working.
How to debug:
- run ea-start in debug mode:
# /opt/SUNWsymon/SunMC-TNG/sbin/ea-start -d9
- check if the Event Adaptor is been setup,
# /var/opt/SUNWsymon/SunMC-TNG/cfg_sunmctotng
- check the CA log file
# /var/opt/SUNWsymon/SunMC-TNG/SunMCToTngAdaptorMain.log
After that is all fine check this side it explains how to discover an SunMC agent from CA Unicenter.

Performance problems related to Timesheet entry and Time Admin processing.
Implementing 9.0, they are in UAT, experiencing performance delays on timeadmin and timesheet page when using apply rules button, they have quite a bit of rules and when number of users increase to 30 concurrent users severe performance issue are experienced on timesheet, at this point they are more concerned with the timesheet performance than the time admin performance, they have delayed their go live date until this issue gets resolved.
In the Performance Monitor data were are getting several failed status' for the PMU 'JOLT Request' and PMU Details 'ICPanel'. In the additional data area it states:
Error Status Code:

BDB read performance problem: lock contention between GC and VM threads
Problem: BDB read performance is really bad when the size of the BDB crosses 20GB. Once the database crosses 20GB or near there, it takes more than one hour to read/delete/add 200K keys.
After a point, of these 200K keys there are about 15-30K keys that are new and this number eventually should come down and there should not be any new keys after a point.
Application:
Transactional Data Store application. Single threaded process, that's trying to read one key's data, delete the data and add new data. The keys are really small (20 bytes) and the data is large (grows from 1KB to 100KB)
On on machine, I have a total of 3 processes running with each process accessing its own BDB on a separate RAID1+0 drive. So, according to me there should really be no disk i/o wait that's slowing down the reads.
After a point (past 20GB), There are about 4-5 million keys in my BDB and the data associated with each key could be anywhere between 1KB to 100KB. Eventually every key will have 100KB data associated with it.
Hardware:
16 core Intel Xeon, 96GB of RAM, 8 drive, running 2.6.18-194.26.1.0.1.el5 #1 SMP x86_64 x86_64 x86_64 GNU/Linux

Diagnosis:
I'm seeing way to much lock contention on the Java Garbage Collector threads and also the VM thread when I strace my java process and I don't understand the behavior.
We are spending more than 95% of the time trying to acquire locks and I don't know what these locks are. Any info here would help.
Earlier I thought the overflow pages were the problem as 100KB data size was exceeding all overflow page limits. So, I implemented duplicate keys concept by chunking of my data to fit to overflow page limits.
Now I don't see any overflow pages in my system but I still see bad bdb read performance.

The above stats show that there is too much time spent locking (futex calls) and I don't understand that because
the application is really single-threaded. I have turned on asynchronous transactions so the writes might be
flushed asynchronously in the background but spending that much time locking and timing out seems wrong.
So, there is possibly something I'm not setting or something weird with the way JVM is behaving on my box.
I grep-ed for futex calls in one of my strace log snippet and I see that there is a VM thread that grabbed the mutex
maximum number(223) of times and followed by Garbage Collector threads: the following is the lock counts and thread-pids
within the process:
These are the 10 GC threads (each thread has grabbed lock on an avg 85 times):

Maybe I should make my application a Concurrent Data Store app as there is really only one thread doing the writes and reads. But I would like
to understand why my process is spending so much time in locking.
Can I try any other options? How do I prevent such heavy locking from happening? Has anyone seen this kind of behavior? Maybe this is
all normal. I'm pretty new to using BDB.
If there is a way to disable locking that would also work as there is only one thread that's really doing all the job.
Should I disable the file system cache? One thing is that my application does not utilize cache very well as once I visit a key, I don't visit that
key again for a very long time so its very possible that the key has to be read again from the disk.
It is possible that I'm thinking this completely wrong and focussing too much on locking behavior and the problem is else where.
Any thoughts/suggestions etc are welcome. Your help on this is much appreciated.

Performance Problems with UI Element Tabstrip and IE
Hi,
I use the UI Element "Tabstrip" in a Java Web Dynpro Application. The application gets slower the more I jump from one tab to the next. All the other UI Elements (e.g. ComboBox, TextField) are affected, too.
A system trace on the Web AS seems to indicate that it is a client problem.
We are using the Internet Explorer 6.0.2900.2180 XP SP2 and the J2EE Engine 6.40.
It seems to be a problem with the Tabstrip element in combination with the IE (Firefox 3 works fine). We created a test application with only the tabstrip element, three tabs, and a combo box. After several clicks on the tabs, the test application gets slower...
Does anyone has had the same problem with the tabstrips, or anyone an idea what might be the reason??
Thanks,

2.1 RC1 - Performance problem, typing lag in EA2 and RC1
Hi!
I have searched and searched the forum but cannot find any reference to this specific issue.. Please accept my apologies if this has already been posted as I can't believe there are no other occurences of this out there
On moving from 1.5.5 to either 2.1 EA2 or RC1, I experience massive performance issues making SQL Developer unusable.
Basically, just typing into a SQL worksheet consumes most of my machine CPU and results in a huge amount of lag: typing a simple SELECT statement will take 10 to 20 seconds just for the text to catch up with my typing! It's infuriating!
I've disabled all of the Code Insight options, ensure the 'Select default path to look for scripts' field is empty and I've tried both the JRE inclusive and exclusive versions all with the same result. If I fire up 1.5.5 I'm immediately back in business with no lag between typing and the display.
My laptop is well spec'd - XP Pro, 2Ghz dual core, 2 GB RAM
Any thoughts other than what I've tried above?
Many thanks in advance!
Edited by: user4523743 on 07-Dec-2009 03:21Okay, this is weird. I can get around this by setting the 'Select default path for scripts' preference to something other than blank!
I'm wondering if this is because a group policy sets the default homedrive / My Documents folder to something on a network share. Could it be that having this value blank is causing SQL Developer to poll this share, and therefore the network, causing the performance issue?
As it is, setting the value to something on the local drive (C:\) seems to fix it - contrary to what other posts have had to say on the matter of this preference! -

([\d]{3}& shy ;[\d]{3}& shy ;[\d]{4}|[\d]{3}& nbsp ;[\d]{3}& nbsp ;[\d]{4})
(which searches for numbers in the 888-555-1234 or 888 555 1234 formats)
This will work fine if I manually enter it into the search text area. However if I save it to file and reload it, it will no longer work because the ­ and characters are now displayed as " " (space) and "-"(shy) rendering the saved query useless as it's no longer searching for the code. I have some fairly long and complex queries and this is becoming a problem.
Thanks for any help.
I'm currently using Dreaweaver CS4 at home and CS5.5 at work.Thanks for your reply Kenneth, but that is not what I'm trying to accomplish. I'm looking for the HTML entities that exist in the source code which are & shy ; and & nbsp ; (without the spaces). As I mentioned above, if I enter them manually in the search box, I will get the corrrect results. If I save the search and then reload it, the special characters are no longer in HTML and the search is now useless.
Just for example again
In an open document in code view insert a number in the format (without the spaces): 888& nbsp;888& nbsp ;8888
Open a search dialog box and enter (without the spaces): [\d]{3}& nbsp ;[\d]{3}& nbsp ;[\d]{4}
The search will find that entry.
Save search as phone.dwr for example. Then load it and try the search again. It won't work because upon loading the search Dreamweaver replaces the HTML code which was saved with the rendered HTML. So now the search shows up as: [\d]{3} [\d]{3} [\d]{4} which will not find the string with hard coded non-breaking spaces that I'm looking for.
Basically I want to be able to save a search query for reuse. When I load a search query, I want it to be exactly what I saved, not something that DW has rendered (that doesn't work). -
Improving performance in a merge between local and remote query
If you try to merge two queries, one local (e.g. table in Excel) and one remote (table in SQL Server), the entire remote table is loaded in memory in order to apply the NestedJoin condition. This could be very slow. In my case, the goal is to import only
those rows that have a product name listed in a local Excel table.
I used the SelectRows by using the list of values of the local query (having only one column) in order to apply an "IN ('value1', 'value2', ...)" condition in the SQL statement generated by Power Query (see examples below).
Questions:
Is there another way to do that in "M"?
Is there a way to build such a query (filter a table by using values obtained in another query) by using the user interface?
Is this a scenario that could be better optimized in the future by improving query folding made by Power Query?
Thanks for the feedback!
Local Query
let
LocalQuery = Excel.CurrentWorkbook(){[Name="LocalTable"]}[Content]
in
LocalQuery
Remote Query
let
Source = Sql.Databases("servername"),
Database = Source{[Name="databasename"]}[Data],
RemoteQuery = OasisDataMart{[Schema="schemaname",Item="tablename"]}[Data]
in
RemoteQuery
Merge Query (from Power Query user interface)
let
Merge = Table.NestedJoin(LocalQuery,{"ProductName"},RemoteQuery,{"ProductName"},"NewColumn",JoinKind.Inner),
#"Expand NewColumn" = Table.ExpandTableColumn(Merge, "NewColumn", {"Description", "Price"}, {"NewColumn.Description", "NewColumn.Price"})
in
#"Expand NewColumn"
Alternative merge approach (editing M - is it possible in user interface?)
let
#"Filtered Rows" = Table.SelectRows(RemoteQuery, each List.Contains ( Table.ToList(LocalQuery), [ProductName] ))
in
#"Filtered Rows"

Power Pivot and SSAS Tabular.Bingo! You've find a serious performance issue!
The very same result can be produced in a fast or slow way.
Slow technique: do the RemoveColumns before the SelectRows (maybe you don't have to apply any transformations to the table you want to filter before the SelectRows - I haven't tested this):
let
Source = Sql.Databases(".\k12"),
AdventureWorksDW2012 = Source{[Name="AdventureWorksDW2012"]}[Data],
dbo_FactInternetSales = AdventureWorksDW2012{[Schema="dbo",Item="FactInternetSales"]}[Data],
#"Removed Columns" = Table.RemoveColumns(dbo_FactInternetSales,{"SalesOrderLineNumber", "RevisionNumber", "OrderQuantity", "UnitPrice", "ExtendedAmount", "UnitPriceDiscountPct", "DiscountAmount", "ProductStandardCost", "TotalProductCost",
"SalesAmount", "TaxAmt", "Freight", "CarrierTrackingNumber", "CustomerPONumber", "OrderDate", "DueDate", "ShipDate", "DimCurrency", "DimCustomer", "DimDate(DueDateKey)", "DimDate(OrderDateKey)", "DimDate(ShipDateKey)", "DimProduct", "DimPromotion", "DimSalesTerritory",
"FactInternetSalesReason"}),
#"Filtered Rows" = Table.SelectRows(#"Removed Columns", each List.Contains(Selection[ProductKey],[ProductKey]))
in
#"Filtered Rows"
Fast technique: do the RemoveColumns after the SelectRows
let
Source = Sql.Databases(".\k12"),
AdventureWorksDW2012 = Source{[Name="AdventureWorksDW2012"]}[Data],
dbo_FactInternetSales = AdventureWorksDW2012{[Schema="dbo",Item="FactInternetSales"]}[Data],
#"Filtered Rows" = Table.SelectRows(dbo_FactInternetSales, each List.Contains(Selection[ProductKey],[ProductKey])),
#"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"SalesOrderLineNumber", "RevisionNumber", "OrderQuantity", "UnitPrice", "ExtendedAmount", "UnitPriceDiscountPct", "DiscountAmount", "ProductStandardCost", "TotalProductCost",
"SalesAmount", "TaxAmt", "Freight", "CarrierTrackingNumber", "CustomerPONumber", "OrderDate", "DueDate", "ShipDate", "DimCurrency", "DimCustomer", "DimDate(DueDateKey)", "DimDate(OrderDateKey)", "DimDate(ShipDateKey)", "DimProduct", "DimPromotion", "DimSalesTerritory",
"FactInternetSalesReason"})
in
#"Removed Columns"
I think that Power Query team should take a look at this.
Thanks!

Performance Problems Bex 7.0 and Office 2007 Workbooks
Hi
we had a performance Problem with Bex 7.0 and Worksbooks in Office 2007.
The Workbooks are created with Office 2003 and runs with good performance but in Office 2007 the performance is inacceptable.
E.g. open Workbook with Office 2003 -- 30 seconds
open Workbook with Office 2007 -- 15 minutes
We do everything what we find in SAP Notes, Whitepapers oder SDN Messages.
For Example:
- We installed all Excel Patches witch descriped in: Microsoft Excel 2007 &
SAP Business Explorer Compatibility
- We set the optimize X: RS_FRONTEND_INIT setting u2018ANA_USE_OPTIMIZE_STG = Xu2019
- We open worksbooks in Office 2007 with the repair Flag.
- We used Flag open in XLS format
But same Workbooks are extrem slow.
We try to create a new Workbook with Office 2007 and it runs with good performance.
But there are 500 Workbooks we didn`t wont to create all new.
System Information:
BW: 7.0 Netweaver 7.01 BI_CONT 7.05
Client: SAP Gui 7.10 BI Explorer: 902
Thank your for your Help.
Edited by: Carsten Ziemann on Feb 2, 2011 4:36 PMHello Carsten,
Try to use Workbook compression:
- Open the specific workbook in BEx Analyzer
- Open Workbook Settings dailog
- Check "Use Optimized Storage"
- Click on OK Button
- Save the workbook
But also, your front end tools are on a very old version.
I would like to recommend you to install the latest patch of SAPGUI 7.20 and Business Explore 7.20.
Front End Version 7.10 will be supported until April 2011.
But, if you want to continue using 7.10, update to latest patch:
http://service.sap.com/swdc
> Support Packages and Patches
> Browse our Download Catalog
> SAP Frontend Components
> SAP GUI FOR WINDOWS
> SAP GUI FOR WINDOWS 7.10 CORE
> Win32

Any help is highly appreciated
Thanks
sahmadHi,
Check these notes:
Note 497289 - Performance when reading shipment
Note 801419 - Performance problems in shipment (cost) processing
and related notes
Too, check if you have implemented BADI's related with shipment costs.
Other way is to do a trace with ST05 to find the bottleneck. Check with a Basis consultant and perhaps you can solve it with a secondary index. But first check the first notes.
Regards,

Performance problem using OBJECT tag
I have a performance problem using the java plugin and was wondering if anyone else was has seen the same thing. I have a rather complex applet that interacts with java script in a web page using the LiveConnect API. The applet both calls javascript in the page and is called by java script.
Im using IE6 with the java plugin that ships with the 1.4.2_06 JVM. I have noticed that if I deploy the applet using the OBJECT tags, the application seems the trash everytime I call a java method on the applet from javascript. When I deplot the same applet using the APPLET tag the perfomance is much better. I would like to use the OBJECT tag because it applet bahaves better and I have more control over the caching.
This problem seems to be on the boundaries of IE6, JScript, the JVM and my Applet (and I suppose any could be the real culprit). My application is IE5+ specific so I can not test the applet in isolation from the surround HTML/JavaScript (for example in another browser).
Does anyone have any idea?
thanks in advance.
