Hierarchical tree item - how to improve performance

I'm loading hierarchical tree item with query.
Problem is that it takes very long to load all the items(300, but can be more) to the hierarchical item.
Query takes 0.5 sec., but loading it into the item with Set_Tree_Property(htree, Ftree.RECORD_GROUP
the code:
PL1 := Create_Group_From_Query('pl1', query);
v_ignore := Populate_Group(PL1); -- 0.5 sec
Ftree.Set_Tree_Property(htree, Ftree.RECORD_GROUP, PL1); -- 3 sec.
Does anyone have any idea what to do to improve tree loading?

Hello,
try to play a little bit with the state-column of your query. If you only display the first hierarchy level
and set the state of the "hidden" nodes to open, I think ist is the state 1, then it works much faster.

How to improve performance of Siebel Configurator

Hi All,
We are using Siebel Configurator to model the item structures. We wrote few constraint rules on that. But while launching the configurator it is taking more time to open.
Even without rules also it is behaving in the same manner.
Any inputs on this could be highly appreciated

How to improve performance of MediaPlayer?

I tried to use the MediaPlayer with a On2 VP6 flv movie.
Showing a video with a resolution of 1024x768 works.
Showing a video with a resolution of 1280x720 and a average bitrate of 1700 kb/s leads to a delay of the video signal behind the audio signal of a couple of seconds. VLC, Media Player Classic and a couple of other players have no problem with the video. Only the FX MediaPlayer shows a poor performance.
Additionally mouse events in a second stage (the first stage is used for the video) are not processed in 2 of 3 cases. If the MediaPlayer is switched off, the mouse events work reliable.
Does somebody know a solution for this problems?
Cheers

How to improve performance when there are many TextBlocks in ItemsControl items?

Hi,
I'm trying to find a way to improve performance for a situation when there is an ItemsControl using UI and Data virtualization and each item on that control has 36 TextBlocks. Basically the item is a single string. There are so many TextBlocks
to allow assigning different brushes to different parts of the string. Performance of this construction is terrible. I have 37 items visible on the screen and if I try to scroll up or down it scrolls into the black space and then it takes a second or two to
show the items.
I tried different things. For example, the most successful performance-wise was to replace TextBlocks with Borders and then draw bitmaps. In other words, I prepared 127 bitmaps for each character (I need ASCII only) and then I used those bitmaps
to set Border.Backgrounds. It improved performance about 1.5 - 2 times but it consumed much more memory (which is not surprising, of course). Required amount of memory is so big that it throws OutOfMemoryException on 512MB emulator but works on 1GB. As a result
I don't thing it is a good solution.
Another thing that worked perfect is to replace 36 TextBlocks with only 6 TextBlocks. In this case the performance improvement is about 5 - 10 times but I lose the ability to set different colors to different parts of the string. It seems that
the performance degrades dramatically with the increase of number of TextBlocks. Is there another technique to draw strings where literally each character can be of different color with decent performance?
Thank you
Alex

Using Runs inside TextBlocks gives approximately the same improvement as using bitmaps 1.5 - 2 times faster but it is not even close to the case with just a couple of TextBlocks in the ItemsControl item. Any other ideas?

How to improve performance on SD document with over 1000 line items

Dear experts,
A lot of our SD document contains 1500 to 5000 line items. Saving a simple change of one line item description would take 5 minutes (with or without pricing considerations). We are on ECC 5.0. Does anyone know of an existing snote or ways that would help to improve performance?
A related question on performance tracing. I have done some tracing and notice that the time to access SQL/buffer/enqueue/RFC only amount to less than 50% (sometimes 5%) of the total processing time. What has the system been doing for the "unrecorded" time?
Thank you and appreciate!
-cynthia

I would check which modules or which parts of code take the most of the processing time. You can use SE30 to check one order save.
If it's not SQL - then it may be internal processing like inefficient loops and so on. For example runtime of nested loops with big tables have grows exponentially.
It may be caused by SAP code - search OSS notes for based on the module names which consume most time.
OR it can be caused by the code in your userexits - then developers have to fix it and redesign using more efficient technique.

Hierarchical Tree. How do I know which node is selected.

Hi All,
I have a Hierarchical tree, How do I know which node is selected
by the user. Similar is the case with list item.
Thank You,
Raj.

Raj,
For the hierarchical tree, use the when-tree-node-activated
trigger and the Ftree.Get_Tree_Node_Property built in to identify
the node that was selected.
For a list box use a when-list-changed trigger. To refer to the
value of the selected list item you can use the block.item
syntax.

HOW TO IMPROVE PERFORMANCE ON SUM FUNCTION IN INLINE SQL QUERY

SELECT NVL(SUM(B1.T_AMOUNT),0) PAYMENT,B1.ACCOUNT_NUM,B1.BILL_SEQ
FROM
SELECT P.T_AMOUNT,P.ACCOUNT_NUM,P.BILL_SEQ
FROM PAYMENT_DATA_VIEW P
WHERE TRUNC(P.ACC_PAYMENT_DATE) < '01-JAN-2013'
AND P.CUSTOMER_NAME ='XYZ'
AND P.CLASS_ID IN (-1,1,2,94)
) B1
GROUP BY B1.ACCOUNT_NUM,B1.BILL_SEQ
Above is the query.If we run inner query it takes few second to execute but while we are summing up the same amount and bill_Seq using inline view, it takes time to execute it.
Note: Count of rows selected from inner query will be around >10 Lac

The two DISTINCTs are redundant, as UNION results in unique records, as a set can't have duplicates.
Other than that the query is not formatted and unreadable, and you didn't provide a description of the tables involved.
Your strategy seems to be maximum help from this forum with minimum effort from yourself, other than hitting copy and paste.

How to improve performance for Custom Extractor in BI..

HI all,
I am new to BI and started working on BI for couple of weeks.. I created a Custom Extractor(Data View) in the Source system and when i pull data takes lot of time.. Can any one respond to this, suggesting how to improve the performance of my custom Extractor.. Please do the needfull..
Thanks and Regards,
Venugopal..

Dear Venugopal,
use transaction ST05 to check if your SQL statements are optimal and that you do not have redundant database calls. You should use as much as possible "bulking", which means to fetch the required data with one request to database and not with multiple requests to database.
Use transaction SE30 to check if you are wasting time in loops and if yes, optimize the algorithm.
Best Regards,
Sylvia

Hierarchical Tree Items question, in Oracle9i forms builder ^^;

Hi,I'm kind of new to using the Hierachical Tree item in Oracle9i Forms builder. so anyway,in the book it was explaining how it's done clearly,but, what I want to do using that item is kind of different;
in the book it has the way of making it like a navigator for the items/fields/tables in the database,either by creating a view for those fields by using Select Statements or using the whole table itself.
however,what I'm trying to do is to have that tree list the names of Forms I have already created and probably the list of Reports I got,so it would sort of like a Menu and I could add a trigger to open the form/report once an item in the tree is double clicked on
here's an example of what I'm talking about :
http://i7.photobucket.com/albums/y264/_Crzy_Chck_/Htree.jpg
sorry the screen shot isn't the best ^^;
that's from a company my friend works at,they have that tree as a menu for their forms and reports,once u double click on a form name or a report,it opens up ^^;
I tried google/yahoo,I got the same info I found on the book.

Or you may want to check out this code:
   PROCEDURE next_menu(
      menu_in                                        IN OUT   NUMBER

   END next_menu;tree_item contains the name of the tree item you are using. the select statement is based on a table that is like EMP, where one EMP van be another EMP's manager. In this table a menu-option can be another menu-option's master.
this is a recursive function that keeps calling itself untill the query finds no more record.
Good Luck!
