How to better the performance while Swing??(urgent)

Hi all,
I am working on a product where there are many applets embedded within the JSPs.So each time when the user go out and again come back to the page,the applets are getting loaded after taking a lot of time(almost 30-40secs).Do please note that all these applets contain a lot of UI controls which would be populted by the user.
Please tell me how to improve the performance of these applets by holding the data once entered by the user.
thnx & rgds,

hi,
One way is to use jar files, Once the jar files are installed on the client machine they dont need to be downloaded every time.

How to improve the Performance of Swing Components

Hi
I have developed a GUI Framework with Swing components. I observed that when number of components are more, the GUI is slow. Could anybody suggest me the ways to improve the performance of Swing Components
Thanks

Hi There - I haven't found issues so far with the speed of the GUI building, it seems fast when compared with .NET applications
Are you doing any database querying on form load? This can slow down the loading of the GUI, I use persistence in an application and before the GUI is shown the persistence unit logs in to the database and registers itself - it does take 2/3 seconds to register and complete whatever it does before the form builds and shows
Also check if you are loading/using any network based files on form load, this can also slow down the building considerably as well. Apart from that it's hard to say where your issue may lie apart from removing controls and checking build speed until you find the one that's slowing it down (not a good approach though) I sometimes had to load csv files from a network drive and if the file server is slow or LAN speed isn't great this can also cause a delay, hope you find it.....

How to improve the performance of Swing Application?

My project is a Swing based application which uses java 1.2.1 API.
The problem is my application is very slow and gets hung many times, inspite of the system configuration being good ( 256 Mb RAM, 733MHz processor).
Do give me some suggestions to improve the performance.
Regards,
sudhakar

The system configuration is more than enough to run java applications.
You are probalbly doing time-consuming operations in the event thread. Which blocks the event thread and the gui seems not to be responding. If you you have a very bad design.
Use a thread for time consuming operations.

How can we improve the performance while fetching data from RESB table.

Hi All,
Can any bosy suggest me the right way to improve the performance while fetching data from RESB table. Below is the select statement.
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.
Here I am using 'KDAUF' & 'ABLAD' in condition. Can we use secondary index for improving the performance in this case.
Regards,
Himanshu

Hi ,
Declare intenal table with only those four fields.
and try the beloe code....
SELECT aufnr posnr roms1 roanz
INTO table itab
FROM resb
WHERE kdauf = p_vbeln
AND ablad = itab-sposnr+2.
yes, you can also use secondary index for improving the performance in this case.

Do you have an idea how to improve the performance ?

Hi All,
Greeting,
I'm doing SEM IP. Regarding the performance, do you have some thought about this ?
So I have planning report for project report . As we know, if we forecast against project, means the date itself is the life of the project itself.
It means it could be more than 10 years (forecast period) and 10 years (actual period). Currently I segregate between actual and forecast into different info cube .
But the performance of the planning report is slow now. Do you have an idea about this how to increase the performance. The performance I mentioned here is when we're going to the report (after putting in the value in the selection screen).
The other question, at this moment, I have a multiprovider than this multi provider consist 2 info cubes ( actual and forecast ). Than my aggregation is sitting on top of that multi-provider .
My question whether that's approach correct or not ? Or do we have to create 1 aggregate (only for forecast), than I have multi-provider consisting forecasting aggregation and actual cube .
than my query will sit on top of that multi-provider ?
Which one is better ??
Thanks a lot all,
really need your help,

Hi,
For the performance tuning, you can consider any of the following three methods,
1. Indices
With an increasing number of data records in the InfoCube, not only the load but also the query performance can be reduced. This is attributed to the increasing demands on the system for maintaining indexes. The indexes that are created in the fact table for each dimension allow you to easily find and select the data.
2. Partitioning
By using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. Thanks to this separation, performance is increased when reporting, or also when deleting data from the InfoCube.
3. Aggregates
Aggregates make it possible to access InfoCube data quickly in Reporting. Aggregates serve, in a similar way to database indexes, to improve performance.
4. Compressing the Infocube
Infocube compression means aggregation of the data ignoring the request idu2019s. After compression, the system need not perform aggregation using the request ID every time you execute a query.
And I feel that as per your scenario, you need to do first compress the data based on user requirements and have only the required data in the infocube.
And for the approach regarding the Aggregation level design, choosing between the two approaches depends on the user requirements. For example,
If you have aggregation level created on top of multiprovider containing actual and forecast cube, in your report (created on top of aggregation level) you can view the key figure values present in both the cubes, which is not possible in the other approach.
So this approach is suited if your requirement is to view the records from both the cubes in your report (Comparing planning and actual values).
The second approach is used if your requirement is only to report on planning forecast cube.
Hopes this solves your issue.

Balajee

I wanted to modify the query, since its taking lot of time to load the data.
Please suggest : -
Treat this is very urgent.

Hi Shyamal,
In your program , you are using "into corresponding fields of ".
Try not to use this addition in your select query.
Instead, just use "into table it_list".
As an example,
Just give a normal query using "into corresponding fields of" in a program. Now go to se30 ( Runtime analysis), and give the program name and execute it .
Now if you click on Analyze button , you can see, the analysis given for the query.The one given in "Red" line informs you that you need to find for alternate methods.
On the other hand, if you are using "into table itab", it will give you an entirely different analysis.
So try not to give "into corresponding fields" in your query.
Regards,
SP.

How bad is the performance hit with RTMPT?

In a conversation with engineers recently at a CDN it was suggested to me that streaming all video over RTMPT only was a viable solution to the barriers posed by firewalls and proxies blocking port 1935. They indicated that they had seen no signifigant performance degradation with tunneling and that many of their clients were making the switch from "rollover" type connection models to connection via RTMPT only.
This ran counter to my notion of the process. I have always thought the packet overhead was signifigant.
Is it? How bad is the performance hit for streaming live h.264 video?

Hmmm... That's quite a hit.
I'm trying to determine the best strategy for reaching the most people with the least performance hit. A guy lays out his strategy here:
http://www.kensodev.com/2010/02/19/rtmp-being-blocked-by-firewalls-flash-media-server/
He basically says ditch 1935. Never use it. Always use 80. Like this:
rtmp://your_ip_address:80/app_name
If that fails, do this:
rtmpt://your_ip_address:80/app_name
Does that seem valid? Does that first option avoid the perfomance hit of tunnelling while getting you more connections? If so, it makes me think there is no benefit at all to connecting via 1935.

How to improve the performance of adobe forms

Hi,
Please give me some suggestions as to how to improve the performance of adobe form?
Right now when I' am doing user events it is working fine for first 6 or 7 user events. From the next
one it is hanging.
I read about Wizard form design approach, how to use the same here.
Thanks,
Aravind

Hi Otto,
The form is created using HCM forms and processes. I' am performing user events in the form.
User events will doa round trip, in which form data will be sent to backend SAP system. Processing will
happen on the ABAP side and result will appear on the form. First 6 or 7 user events works correctly,
the result is appearing on the form. Around 8 or 9th one, the wait symbol appears and the form is not
re-rendered. The form is of size 6 pages. The issue is not coming with form of size 1 page.
I was reading ways to improve performance during re-rendering given below.
http://www.adobe.com/devnet/livecycle/articles/DynamicInteractiveFormPerformance.pdf
It talks about wizard form design approach. But in SFP transaction, I am not seeing any kind of wizard.
Let me know if you need further details.

How to measure the performance of sql query?

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
         SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
         OBJECT_NAME,
         CARDINALITY,
         LAST_OUTPUT_ROWS,
         LAST_CR_BUFFER_GETS,
         LAST_DISK_READS,
         LAST_DISK_WRITES,
FROM     V$SQL_PLAN_STATISTICS_ALL P,
         (SELECT *
          FROM   (SELECT   *
                  FROM     V$SQL
                  WHERE    SQL_TEXT LIKE '%findme%'
                           AND SQL_TEXT NOT LIKE '%V$SQL%'
                           AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
                  ORDER BY LAST_LOAD_TIME DESC)
          WHERE ROWNUM < 2) S
WHERE    S.HASH_VALUE = P.HASH_VALUE
         AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

How to see the object while moving on the artboard?

hello everyone;
maybe a silly question; how to see the object while moving on the artboard? i dont wanna see only the objects bounding box(outline of the object). i wanna see the object it self. thank you.

What have they gone and messed up now?
When I drag an object (with bounding boxes turned on), the object moves and the bounding box stays still until I stop dragging, upon which it snaps to the object’s new position.
If I don’t have bounding boxes turned on (as I usually work), the object moves when dragged.
If what Bedri says is right, they’ve gone and mended something that wasn’t busted.

Waiting for quick response.
Best regards,
BDP

Bansidhar,
1) You need to add a check to make sure that internal table t_dels_tvpod (used in the FOR ALL ENTRIES clause) is not blank. If it is blank skip the SELECt statement.
2) Check the performance with and without clause 'AND lfart NOT IN r_del_types_exclude'. Sometimes NOT causes the select statement to not use the index. Instead of 'lfart NOT IN r_del_types_exclude' use 'lfart IN r_del_types_exclude' and build r_del_types_exclude by using r_del_types_exclude-sign = 'E' instead of 'I'.
3) Make sure that the table used in the FOR ALL ENTRIES clause has unique delivery numbers.
Try doing something like this.
TYPES: BEGIN OF ty_del_types_exclude,
         sign(1)   TYPE c,
         option(2) TYPE c,
         low       TYPE likp-lfart,

      t_del_types_exclude TYPE TABLE OF ty_del_types_exclude,
      t_dels_tvpod_tmp    LIKE TABLE OF t_dels_tvpod        .
IF NOT t_dels_tvpod[] IS INITIAL.
* Assuming that I would like to exclude delivery types 'LP' and 'LPP'
CLEAR w_del_types_exclude.
REFRESH t_del_types_exclude.
w_del_types_exclude-sign = 'E'.
w_del_types_exclude-option = 'EQ'.
w_del_types_exclude-low = 'LP'.
APPEND w_del_types_exclude TO t_del_types_exclude.
w_del_types_exclude-low = 'LPP'.
APPEND w_del_types_exclude TO t_del_types_exclude.
t_dels_tvpod_tmp[] = t_dels_tvpod[].
SORT t_dels_tvpod_tmp BY vbeln.
