How can i improve jsf application? It eat a lot of CPU.

I use only request beans, state save method is server.
How can I improve it, what is with state manager, save state tree.?

Profile your application and find the CPU hotspots. Then you can figure out what needs improvement.

How can I improve below SQL performance.

Hi,
How can I improve below SQL performance. This SQL consumes CPU and occures wait events. It is running every 10 seconds. When I look at the session information from Enterprise Manager I can see that "Histogram for Wait Event: PX Deq Credit: send blkd"

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:
SELECT i.ID
FROM EXPRESS.invoices i
WHERE i.nbr IS NOT NULL
AND i.EXTRACT_BATCH IS NULL

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.

Yoo

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 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 picture quality...now grainy after IOS update!

How can I improve picture quality...now grainy after IOS update!

Hello, dreamer5th.
Thank you for visiting Apple Support Communities.
Here are some troubleshooting steps that I would recommend going through when experiencing this issue. They are labeled for the iPhone; however, the steps also apply to your iPad. Also, make sure to test the camera in well lighted conditions as this can affect picture quality.
Camera isn't functioning or has undesired image quality
If the screen shows a closed lens or black image, force quit the Camera app.
If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
Cases can interfere with the camera and the flash. Try gently cleaning the lens with a clean dry cloth or removing the case if you see image or color-quality issues with photos.
Try turning iPhone off and then back on.
Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
Try to remain steady while focusing:
Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center.
Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
Video: Adjust focus before you begin recording. You can also tap to readjust focus while recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll.
Note: Video-recording features are not available on original iPhone or iPhone 3G.
If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.

If the issue persists see the last section labeled Issue not resolved.

It sounds like you essentially have a new computer and unless you restored from a backup your iTunes library would be empty. You can transfer your iTunes purchases from your iPod to the computer by:
iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
SInce you changed syncing computers. after you move the stuff you need to restore the iPod to factory defaults and sync the stuff back to your iPod. If you had the iPod backup file you could restore from backup.
If you have non-iTunes pruchases you can copy them to your computer by using one of the third-party programs discussed in this previous discussion:

How can I execute external application?

Hi friends I want printing my barcodes a laser printer (Kyocera) it isn't a barcode printer. So I think (and I look kyocera web page my model doesn't support barcode printing in sap) print my barcodes using an external system. Before SAP we are using JollyPrint application for printing barcodes. It is using an Excel file.
I can create a excel file for this application. I must execute this (JollyPrint-it is a label application) application when I press a button. How can I execute this application?
Thanks
Mehmet
P.S. I have been writing this message with details may be somebody can give me a simple way for this

Well, I can suggest you following steps. May be it works for you .
-Create an external OS command in SM69
-Test OS command in SM49 ( about OS command if you search in SDN youll get lot of material )
-Create a Script at your OS level, Im assuming you might have some UNIX flavor or Sun solarias.
-Create a Shell script , which execute the printer job from OS .
-Shell script will have parameters . ( e.g. printer name, destination etc )
-set the path of shell script directory in SM69 ( the command you just created )
-Execute shell script using your ABAP program ( use FM "SXPG_COMMAND_EXECUTE" )
In the ABAP program you can pass the parameters and execute the command from ABAP as a result your job will start printing on the required destination. Moreover, you can also capture the spool at OS level .
FYI
For UNIX script, if you search in www.google.com ( UNIX forums) . youll get shell script .
Hope thisll give you idea!!
P.S award the points.
Good luck
Thanks

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 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.

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.
