How to Improve Perfomance of JavaApp with several tabs in JDeveloper

Hi,
One of my screens in my java application has several tabs. The master detail relationship is defined in a MDPanel using bindNestedContainer/findNestedPanelBinding constructs. If there are several wiews being linked to the master record, performance is not good.
In Forms builder, we encounter the same problem. The solution there is to remove the relations and dynamically set the where clause using the block property. Can I do the same in JDeveloper? If yes, where is this best implemented? AppModule or in the UI?
I appreciate if you can give sample code or a reference where I can understand fully the Entity/View/AppModule framework. Currently, I am dependent on the wizard to create these objects. How can I optimize the wizard generated code?
Thanks.

Hi,
Removing viewlinks and using query bind variables have improve the performance significantly. Thank you for your suggestion.
However, my next concern is on data creation. What is the equivalent of WHEN-CREATE-RECORD in Forms? The ffg. set of codes does not seem to work.
panelBinding.addRowSetListener(new PanelRowSetHandler());
private class PanelRowSetHandler extends JUPanelRowSetAdapter {
public void rowInserted(JUIteratorBinding iter, InsertEvent event) {
if (iter.equals("EndorsementMembers")) {
String branch = (String)panelBinding.findCtrlValueBinding("branch").getAttributeValue();
Integer endorsTransNo = (Integer)panelBinding.findCtrlValueBinding("endorsTransNo").getAttributeValue();
panelBinding.findCtrlValueBinding("EndmembBranch").setAttributeValue(branch);
panelBinding.findCtrlValueBinding("EndmembEndorsTransNo").setAttributeValue(endorsTransNo);
Also, I am wondering whether I can access the create method of the Entity Object in the View Object so that I can just pass the parameter values defined here.
Thanks and regards,
Angela

Create home page with several tabs upon opening Safari

I would like to create a home page with several tabs upon opening Safari is this possible?

Yes, it's possible.
First create a folder of bookmarks containing the pages you want to have appear as tabs when you start Safari.
Once you've got that bookmarks folder set up, go into your General Safari preferences. At "New windows open with:" select "Choose tabs folder ..." as per the following screenshot:
.... and select the bookmarks folder you set up before.
Quit and restart Safari. Do the contents of the bookmarks folder open in tabs in a new window?
(To change what tabs you have opening in a new window, just change the content of the bookmarks folder you've selected in your preferences.)

When I minimize ff with several tabs I can maxamize the one I was on straight away but any other one I have to click twice, why?

when I minimize my ff with several tabs it goes to my task bar with a number of shadows equal to the tabs I have opened if I mouse over it I get small previews of the tabs open and I can open the one I was on last straight away but if I click on any other I get a beep and then nothing so I have to do the same thing again before it will open to a different tab, why?

Odd thing when ff is maximized and I go to the preview in the windows task bar I can click on any tab and it will open right away it's only when ff is minimized that I have to click twice. fyi I have tab previews checked and I have tried to unset it the reset it to see if that would help but no go.

How to authorise single Ereader device with several Adobe IDs?

Is it technically possible in Adobe's DRM system to connect a single epub ebook reader with several Adobe Digital Editions IDs?
The background of my question is following: I got an ADE account and a laptop computer and Ereader authorised with that account. My wife got an ADE account of her own and her computer and her own Ereader authorised with her account. So both of us got 4 more devices to be authorised with if I understand the system right.
What I have in mind is to authorise my wife's Ereader with my ADE account, too, in order to be able to transfer DRM protected epub ebooks that I purchased under my account to her Ereader. But I'm afraid to overwright the original authorisation on her Ereader by authorising it with my Adobe ID and therefore restrain from fiddling with the device authorisation.
Any advise by Adobe or someone else in the community? I was not able to find any useful advise in various forums.
Many thanks for help!
Best regards,

How to make a panoramic view with several photos

With Iphoto 09 is there a way to create a panorama with several pictures and pull them altogether?? thank you

No, you need to use a third party app for this kind of work. Some cameras come with an app that will do this. Otherwise search on MacUpdate

When one window containing 1 tab is closed, the other window with several tabs closes also

I have a set of web pages that reproducibly causes Firefox to act incorrectly. When Firefox is first started I click the "Restore previous desktop" button. Then I have 2 Firefox windows. The first to open has 6 tabs; the second has 1 tab. When I close the 2nd window (with 1 tab), it also closes Firefox completely with no error message. When I run Firefox again, "Restore" creates both windows exactly as they were before.
I don't know yet if the actual URLs make a difference, but here they are anyway:
'''''Window 1:'''''

***** NOTE THIS TAB IS PROBLEMATIC *****
When I press Alt+D, Ctrl+C, and Ctrl+V it into this comment box, I get
'''woot'''
When I look at the actual contents of the web page being displayed, it is the verizon wireless rebate page:
'''www.verizonwireless.com/rebates'''
The page has definitely finished being rendered (the refresh icon is displayed after the url "woot"), but the URL does not match the page. The URL displayed is not even in its proper form (i.e., www.woot.com).
Remember that this page was RESTORED by Firefox from a previous session. It is as if I was on that tab at verizon, tried to go to woot.com by typing "woot" (which would of course bring up a search rather than the web page), DIDN'T PRESS ENTER, and Firefox is duplicating that entire sequence.

'''''Window 2:'''''

With this exact set of windows and tabs, as restored by Firefox in a brand new instance of it, double-clicking the red Firefox in the top left corner of the 2nd window causes both windows to close.
I wish I could save this configuration so I could always reproduce the error, but I need my computer :)

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.
*Help > Troubleshooting Information > Profile Directory: Open Containing Folder
*http://kb.mozillazine.org/Profile_folder_-_Firefox
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

How do I merge multiple windows into 1 window with several tabs?

In Safari it is possible to merge several open windows into 1 single window, with each window becoming a new tab within the new window, so you can easily switch from tab to tab. I cannot find how to do this in Firefox - does anyone know if it is possible? Thanks.

Try Tab Mix Plus.

How to Print one PDF document (with several documents inside) at once?

When I select several emails and convert them into one single PDF file, I would like to know how can I print (hardcopy print) all emails at once, instead of having to select each one at a time to prit it.
I have ADOBE Acrobat X Pro V10.
Can anyone help me with this? It would save a lot of time.
Thank you

I am using XI and it has a better print dialog for portfolios, but I think this Adobe blog link explains what you need for X:

Not sure why the link I posted above looks like is has spaces, but there are no spaces in the link.

How to Improve perfomance of this query

Hi,
Please help me to improve this query performance. Objective of this query is to find out individual count who order the product in last two year and create a matrix with time period
Challenge is Both the table having more than 600 million record so it is taking to much time to execute
SELECT count(unique b.individual_id),
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 45 THEN 1 ELSE 0 END )) AS one_month ,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 105 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 45 THEN 1 ELSE 0 END )) AS Three_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 195 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 105 THEN 1 ELSE 0 END )) AS six_month,

Challenge is Both the table having more than 600 million record so it is taking to much time to execute Dombrooks has provided you with an excellent response.
In addition, you should mention how much time the query is currently taking and how much do you expect it to take, what is your database version etc.
One of the most important thing is to post your SQLs and EXPLAIN PLAN outcomes in readable format. You can do this by wrapping it within \ and \ tags.
Now, based on the limited details that you have provided, following are my questions/observations:
a) You claim that both tables have more than 600 million rows but your plan shows that optimizer is expecting to find only 46 million rows in ORDER table. You may want to confirm if statistics on both the tables are correct.
b) Your plan appears to suggest that the UNIQUE is not affecting the query results. Based on your knowledge of your data, do you need the COUNT(UNIQUE individual_id) or can it be just COUNT(individual_id)?
c) Finally, if you are interested in only last two years of data, you should probably have a WHERE predicate on your ORDER table which filters data based on ORDER_DT. Something like following:
SELECT count(unique b.individual_id),
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 45 THEN 1 ELSE 0 END )) AS one_month ,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955'))>= SYSDATE - 105 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 45 THEN 1 ELSE 0 END )) AS Three_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 195 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 105 THEN 1 ELSE 0 END )) AS six_month,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 380 and NVL(ORDER_DT,TO_DATE('05-MAY-1955')) <= SYSDATE - 195 THEN 1 ELSE 0 END )) AS one_year,
sum((CASE WHEN NVL(ORDER_DT,TO_DATE('05-MAY-1955')) >= SYSDATE - 745 and NVL(ORDER_DT,TO_DATE('05-MAY-1955'))<= SYSDATE - 380 THEN 1 ELSE 0 END )) AS two_year

where b.individual_id = a.individual_id

How to improve perfomance in database operations

In my programme i do some select, insert operations many time. so when i run my program with atlease 80000 customer data it takes 1 hrs to complete the task.
So i switched to use threads. So i use n number of threads and gave a new connection to each thread and splited my customer data for each threads. so each thread contain 80000/n data.
when i check the perfomance both (with and without thread) are equal
so help me to improve the perfomance :)

s friend. most of the time it invokes the database operations. i use addbatchs to execute the code. wait i will give the timelines,

How to print a Vbox container with several pages

I need to print a Vbox container that contains severval pages
of content with .5 inch margins and a footer with the page number.
The content is created from htmlText coming from several reccords
in a MySQL table. I have been able to print the content using
FlexPrintJob across multiple pages, but the print fills the entire
page with no margins and the footer only on the last page. How can
I best do this?

I had a similar issue, here are some tips:
Check Flex's example for printing a PrintDataGrid in mulitple
pages (
http://livedocs.macromedia.com/flex/2/langref/mx/printing/PrintDataGrid.html
or in the Printing chapter of the Flex Developer's Guide), that
will give you an idea of how to handle the footer and the header.
Now about the margins you will have to do it manually, i
can't think of any other solution for that.
If you still have doubts, let me know about it, trying to be
as specific as possible

How to display a long text with several in multiple lines in template cell

Hi,
   here i have one string such as 'Power MOS_TestTestTest'. But it will display in the template cell as
   'Power
   MOS_TestTestTest'.
   And what i want is 'Power MOS_TestTes
                               tTest'.
How to achieve this ? ths

Hi,
If the Width of the Templete in not sufficient to display whole text then from the next word it is dislpayed in the next line. As in your case ..
'Power
MOS_TestTestTest'.
If you want to have this like
'Power MOS_TestTes
tTest'.
You need to write the logic to split the string as per your rquirement and print them.
