Webservice response times --How can we improve ?

Hi All,
I am making two different calls to a Function module from java
1. web service 2. Jco
When I go to STAD transaction i can see webservice response timings are more compared to Jco.
What intresting here for is CPU timings and DB timings.
Some case The DB timings for webservice 3 to 4 times more than Jco .
Ideally DB timings should be similar in both the cases..right ??
CPU timngs also more in webservice ? Why ? How we optimze this for good performance of web service ??
My webservice is simple one conatins 4 input parmaters (simple type) retuening a simple structure.
Jco response time is around 500-2000 (ms)
web service response time is 2000-5000 (ms)
Looking for expert suggestions from our community
Thanks in advance.
Best Regards,Anilkumar

hi,
JCo is an native binary RFC oder FastRFC, walks through the Gateway,
Webservice are textoriented, more Overhead and in summary with still less performance,
walks through the ICM
e.g. RFC-Connections are ca. 10 times faster than Webservices!

Large records retrieve from network took too much time.How can I improve it

HI All
I have Oracle server 10g, and I have tried to fetch around 200 thousand (2 lack ) records. I have used Servlet that is deploy into Jboss 4.0.
And this records come from network.
I have used simple rs.next_ method but it took too much time. I have got the only 30 records with in 1 sec. So if I want all these 2 lacks records system take around more than 40 min. And my requirement is that it has to be retrieve within 40 min.
Is there any another way around this problem? Is there any way that at one call Result set get 1000 records at one time?
As I read somewhere that “ If we use a normal ResultSet data isn't retrieved until you do the next call. The ResultSet isn't a memory table, it's a cursor into the database which loads the next row on request (though the drivers are at liberty to anticipate the request). “
So if we can pass the a request to around 1000 records at one call then maybe we can reduce time.
Has anyone idea How to improve this problem?
Regards,
Shailendra Soni

That true...
I have solved my problem invokeing setFetchSize on ResultSet object.
like ResultSet.setFetchSize(1000).
But The problem sorted out for the less than 1 lack records. Still I want to do the testing for more than 1 lack records.
Actually I had read a one nice article on net
[http://www.precisejava.com/javaperf/j2ee/JDBC.htm#JDBC114]
They have written a solutions for such type of the problem but they dont give any examples. Without examples i dont find how to resolve this type of the problem.
They gave two solutions i,e
Fetch small amount of data iteratively instead of fetching whole data at once
Applications generally require to retrieve huge data from the database using JDBC in operations like searching data. If the client request for a search, the application might return the whole result set at once. This process takes lot of time and has an impact on performance. The solution for the problem is
1. Cache the search data at the server-side and return the data iteratively to the client. For example, the search returns 1000 records, return data to the client in 10 iterations where each iteration has 100 records.
// But i don't understand How can I do it in java.
2. Use Stored procedures to return data iteratively. This does not use server-side caching rather server-side application uses Stored procedures to return small amount of data iteratively.
// But i don't understand How can I do it in java.
If you know any one of these solutions then can you please give me examples to do it.
Thanks in Advance,

Hello there, there is a rare window that keeps popping up every time i start Logic. I'd like to send a screenshot... anyway, it's a "tempo" window with strange layout about midi effects and so,.... is it normal? How can i improve this? Thanks.

hello there, there is a rare window that keeps popping up every time i start Logic. It's a "tempo" window with strange layout about midi effects and so,.... is it normal? How can i improve this? Thanks.

Hmm, that's some sort of MIDI Arpeggiator setup in your environment. Strange that you don't know it, this has to be custom-installed, it is not part of the standard setup.
You can do two things about it:
1.unlock your current screenset (shift-L), then close the (Bass Driver) window, then relock the screenset (shift-L). Next time you open up this project you won't see the Bass Driver, but it is still in the project.
2. You can remove the whole page: open the Environment (cmd-8), then go to the dropdown menu arrow top left of the Environment window and select the Bass Driver layer. If it is selected, dropdown again and choose Delete. Now Save your project under a different name (Save As...), so that you still keep the Bass Driver setup in the original project. If you don't need to keep it, you can simply Save.

Mac book pro stops responding after Maverick OS restart. Currently have a circle with a line through it after 20+ hours. Tried to shut it down and use the Time Machine to restore but no response. How can I restore with Time Machine if it will not start?

sonjadg,
you can purchase a replacement pair of grey installation DVDs for your MacBook Pro from either Apple or iFixit. If Startup Manager is only showing an OS X Installer volume, then it sounds like the Mavericks installer had a problem midway through its installation process. To fix this, you’re going to need to erase your internal disk and reïnstall your original version of OS X from the grey Mac OS X Install DVD, use Software Update to get it back to 10.6.8 (presuming that your MacBook Pro originally came with Snow Leopard), and then restore from Time Machine.

Hi there skmonirul,
Welcome to Apple Support Communities.
From what I gather, iMessages are taking longer than expected to send on your iPhone 4s. If you aren’t seeing issues with other apps, try restarting your iPhone as shown here:
Restart or reset your iPhone, iPad, or iPod touch - Apple Support
If the issue persists, try restoring your iPhone as shown in the article below.
Use iTunes to restore your iOS device to factory settings - Apple Support
So long,

How can I improve my phone signal most of the time I have no service

How can I improve my signal - my old android phone had a brilliant signal however more often than not I have no signal on the iphone

Like Peter said, attitude doesn't help, we need all the information possible to construct a picture of whats going on. Plus, the number of people here to help that are from the UK is limited, so chill out, drink some tea, have a scone and then lets talk
Anyways, since you're in Europe, are you using a provider that uses EE's towers? or EE themselves?
I ask because some MVNO providers are only licensed to use one spectrum. I know this because of the provider 3/Three. Coming from a stay Austria, I can use any 3 partner network but only on 3G, not LTE, 4G, or GSM.
But since it's a service issue, talk to your provider accordingly. Ask them what frequency bands are coming from the tower you're nearest to, or you can check it out yourself with the Field Test Mode.

How can I improve the stability of itunes64bit 8.0.2 on my Vista system?

Vista Home Premium: iTunes64bit: application crashes after adding album photos and then changing views (list, Album, split) or clicking on different playlists and back to the entire music library.
The library has 42,000 items (mostly music) so it is quite large. At launch it takes a long time for itunes to load and display. There is no user cues telling me it is running. It simply displays after 60 or more seconds.
Then I start working in the library, pasting pictures to multiple items, modifying album titles.
After doing a few management tasks on my music items and navigating back and forth between the music library and playlist (changing views), the application stop being responsive and according to the log, the app just plainly crashes.
Sometimes I can restart successfully but most of the times, I need to stop the itunes service or log-out before I can restart it successfully.
I am using itunes64bit 8.0.2
I am running it on a machine equipped with 4GB of ram and the library lives on a 500GB external hard drive plugged-in through USB 2.0.
How can I improve the stability of itunes64bit on my system?

My videos from my iphone are horrible when I transfer them to my PC. How can I improve the video on my PC? Can I just convert the files to WMV? When the video plays the speed is off, it's half slow-motion and staggers into normal play. The clips are slightly cut as well, the clips do not roll continuously. I'm taling about videos that are no more than 2 minutes long. I'm frustrated and I could really use some advice-my kids basketball games is what I'm recording and I'm trying to send them to my family (they are not very tech savvy). Thanks

Not it's only function but one for which it was most admirably suited, which is why I really hope someone can find a work around. I am hoping my post to the Apple feedback may prompt a useful response from Apple and I live in hope that my post here will elicit a useful response from another user. I did not miss the the text at the top of the feedback form but you presumably missed my initial text, 'someone here can explain' or my subsequent 'work around from another user'
Just in case anyone reading this has a large collection of music videos, video podcasts or iTunes U then DO NOT upgrade your iPad to iOS 5. If you are considering purchasing the iPad as a useful mobile device to experience these media organised in your iTunes please don't as you will be wasting your money. (unless someone on this forum knows of a way to undo the mess created by those infallible folks at Apple)

How Can we improve the report performance..?

Hi exports,
I am learning the Business Objects XIR2, Please let me know How Can we improve the report performance..?
Please give the answer in detailed way.

First find out why your report is performing slowly. Then fix it.
That sounds silly, but there's really no single-path process for improving report performance. You might find issues with the report. With the network. With the universe. With the database. With the database design. With the query definition. With report variables. With the ETL. Once you figure out where the problem is, then you start fixing it. Fixing one problem may very well reveal another. I spent two years working on a project where we touched every single aspect of reporting (from data collection through ETL and all the way to report delivery) at some point or another.
I feel like your question is a bit broad (meaning too generic) to address as you have phrased it. Even some of the suggestions already given...
Array fetch size - this determines the number of rows fetched at a single pass. You really don't need to modify this unless your network is giving issues. I have seen folks suggest setting this to one (which results in a lot of network requests) or 500 (which results in fewer requests but they're much MUCH larger). Does either improve performance? They might, or they might make it worse. Without understanding how your network traffic is managed it's hard to say.
Shortcut joins? Sure, they can help, as long as they are appropriate. [Many times they are not.|http://www.dagira.com/2010/05/27/everything-about-shortcut-joins/]
And I could go on and on. The bottom line is that performance tuning doesn't typically fall into a "cookie cutter" approach. It would be better to have a specific question.

How can we improve performance while selection production orders from resb

Dear all,
there is a performance issue in a report which compares sales order and production order.
Below is the code, in this while reading production order data from resb with the below select statement.
can any body tell me how can we improve the performance? should we use indexing, if yes how to use indexing.
*read sales order data
SELECT vbeln posnr arktx zz_cl zz_qty
INTO (itab-vbeln, itab-sposnr, itab-arktx, itab-zz_cl, itab-zz_qty)
FROM vbap
WHERE vbeln = p_vbeln
AND   uepos = p_posnr.
    itab-so_qty = itab-zz_cl * itab-zz_qty / 1000.
    CONCATENATE itab-vbeln itab-sposnr
       INTO itab-document SEPARATED BY '/'.
    CLEAR total_pro.
**read production order data*
    SELECT aufnr posnr roms1 roanz
    INTO (itab-aufnr, itab-pposnr, itab-roms1, itab-roanz)
    FROM resb
    WHERE kdauf = p_vbeln
    AND   ablad = itab-sposnr+2.

Himanshu,
Put a break point before these two select statements and execute in the production.This way you will come to know which select statement is taking much time to get executed.
In both the select statements the where clause is not having the primary keys.
Coming to the point of selecting the data from vbap do check the SAP note no:-185530 accordigly modify the select statement.
As far as the table RESB is concerened here also the where clause doesn't have the primary keys.Do check the SAP Note No:-187906.
I guess not using primary keys is maring the performance.

How can I Improve the Performance using Global Temo Tables ??

Hi,
Can anyone tell me , How can i make use of Global Temporary Tables to improve the Performance.
I have few sample scripts ,
Say i have the View based on some Complex query like ,
CREATE OR REPLACE VIEW Profile_values_view AS
SELECT d.Profile_option_name, d.Profile_option_id, Profile_option_value,
u.User_name, Level_id, Level_code
FROM Profile_definitions d, Profile_values v, Profile_users u
WHERE d.Profile_option_id = v.Profile_option_id
AND ((Level_code = 'USER' AND Level_id = U.User_id) OR
(Level_code = 'DEPARTMENT' AND Level_id = U.Department_id) OR
(Level_code = 'SITE'))
AND NOT EXISTS (SELECT 1 FROM PROFILE_VALUES P
WHERE P.PROFILE_OPTION_ID = V.PROFILE_OPTION_ID
AND ((Level_code = 'USER' AND
level_id = u.User_id) OR
(Level_code = 'DEPARTMENT' AND
level_id = u.Department_id) OR
(Level_code = 'SITE'))
AND INSTR('USERDEPARTMENTSITE', v.Level_code) >
INSTR('USERDEPARTMENTSITE', p.Level_code));
Now i have created the Global temp Table as ,
CREATE GLOBAL TEMPORARY TABLE Profile_values_temp
Profile_option_name VARCHAR(60) NOT NULL,
Profile_option_id NUMBER(4) NOT NULL,
Profile_option_value VARCHAR2(20) NOT NULL,
Level_code VARCHAR2(10) ,
Level_id NUMBER(4) ,
CONSTRAINT Profile_values_temp_pk
PRIMARY KEY (Profile_option_id)
) ON COMMIT PRESERVE ROWS ORGANIZATION INDEX;
Now I am Inserting the Records into Temp table as
INSERT INTO Profile_values_temp
(Profile_option_name, Profile_option_id, Profile_option_value,
Level_code, Level_id)
SELECT Profile_option_name, Profile_option_id, Profile_option_value,
Level_code, Level_id
FROM Profile_values_view;
COMMIT;
Now what my doubt is, when do i need to execute the Insert Statement.
Say , if the View returns few millions of records , then loading such a data into Global Temporary table takes lot of time.
Then what is the use of Global Temporary tables and how can i improve the Performance using the same.
Raj

Thanks for the responce ,
There are 2 to 3 complex views in our database, and there always be more than 5000+ users will be workinf on the application and is OLTP application. Those complex views are killing the application performance.
I what i felt was, if i create the Global Temporary tables for thow views and will be able to load the one third million of records returned by the views in to cache and can improve the application performance.
I have created the Global Temporary tables for 2 views with the option On Commit Preserve , But after am inserting the records into the Temp table and when i Issue the commit statement, the Temp table is getting Cleared.
I really got surpised of this behaviour as i know that with the Option On Commit Preserve , the rows should retain in the Temp Table, Instead , it's getting cleared.
Pelase suggest , what to do ??

How can I improve performance for BC4J/JSP-application

Hi,
I have developed a JSP-Applikcation with the master-detail views. This Application has been implemented
as SSO enabled web portlet into portal. Whenn I click on a row retrieved from the master view (Master.jsp), it take 15 seconds
until the associated data in detail view will be displayed on the other window(Detail.jsp). The master table has about 2500 records and detail table about 7000. (Other case: it takes 2 seconds for 162 rows (master) and 228 rows (detail) respectively)
In Master.jsp I set rangesize = "10" to reduce data loading time.
======================== master.jsp =================================
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView" rangesize="10">
<a href="detail.jsp?RowKeyValue=<jbo:ShowValue datasource="dsMaster" dataitem="RowKey"/>">
Here Click
</a>
==================================================================
Because all records from master view have firstly to be retrieved to locate right row, I set rangesize="-1" in detail.jsp. Consequently this leads to a lower performance.
When rangesize="20" sets instead rangesize="-1", The performance is good, but the wanted Data from detail view are not displayed if the records of master view cliked on ist not in this range.
======================== detail.jsp ======================================
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView" rangesize="-1">
<jbo:RefreshDataSource datasource="dsMaster">
<jbo:Row id="msRow" datasource="dsMaster" action="Find" rowkeyparam="RowkeyValue">
<jbo:dataSource id="dsDetail" appid="testAppId viewobject="DetailView">
======================================================================
Is my programming logic not to be suited for the high performance?
How can I improve the performance, if it is so?
Many thanks for your help.
regards,
Yoo

Welcome to the forum.
I created some indexes. I heard that the indexes are not used when there is a NULL but when I checked the xecution plan It uses index. What columns are indexed?
And what do:
select i.sub_type
,      count(*)
from   express.invoices i
where i.nbr is not null
and    i.extract_batch is null
group by i.sub_type; and
select i.sub_type
,      count(*)
from   express.invoices i
group by i.sub_type; return?
Also, try use the {noformat}{noformat} tag when posting examples/execution plans etc.
See: HOW TO: Post a SQL statement tuning request - template posting for more tuning instructions.
It'll make a big difference:

How can I improve reception?

I have a MiFi 5110L and live in a rural area. How can I improve reception so pages don't freeze and go unresponsive so frequently?

I routinely get -100dBm reception. I don't usually get an error message; I
just drop from 3G to 1X. I'm in 85545. I've found I get better reception
in the motorhome than I do in the house. I had such a hard time getting
the sim card in the first time I'm hesitant to take it out, but if I keep
having problems, I'll try that. I know that living so rural means I don't
get the same reception as I would in a metro area. Would installing an
antenna of some sort help reception? What type of antenna should I install?
Thanks for the help.
