Scrolling of large amount of data with Unscrolled HEADER .How to do???

I am in much need of scrolling a large amount of data without scrolling the header,i.e. while scrolling,only data will be scrolled,so that I can see the header as well.I am using JSP in struts framework.Waiting for your help friends.Thanks in advance.

1) Install Google at your machine.
2) Open it in your favourite web browser.
3) Note the input field and the buttons.
4) Enter smart keywords like "scrollable", "table", "fixed" and "header" in that input field.
5) Press the first button. You'll get a list of links.
6) Follow the relevant links and read it thouroughly.

Sorting large amounts of data with treemap

Hello. Im doing a project where I have to sort a large amount of data. The data is formed by a unique number and a location (a string).
Something like this
NUMBER .... CITY
1000123 BOSTON
1045333 HOUSTON
5234222 PARIS
2343345 PARIS
6234332 SEATTLE
I have to sort the data by location and then by unique number...
I was using the TreeMap to do this : I used the location string as a key - since I wanted to sort the data by that field - but, because the location string is not unique, at the moment to insert the data on the TreeMap, it overwrites the object with the same location string, saving only the last one that was inserted.
Is there any Collection that implements sorting in the way that I need it?... or if there isnt such thing... is there any collection that supports a duplicated key object???
Thanks for your time!
Regards
Cesar

... or use a SortedSet for the list of numbers (as the associated value for
the location key). Something like this:voidAddTuple(String location, Integer number) {
   SortedSet numbers= set.get(location);
   if (numbers == null)
      set.put(location, numbers= new TreeSet());
   numbers.put(number);
}kind regards,

Best strategy to retrieve large amount of data with EJB ?

Hi all
I have an EJB 3 which is fronted by a Web Service. The EJB retrieves a large amount of objects (TaskList) and returns it to the client.
@Stateless
public List <TaskList> findByRole(String role){
List <TaskList> tasklist = em.createNamedQuery("findByRole")
.setParameter("Role", role)
.getResultList();
return tasklist;
}The problem is the query is rather slow but especially returning lots of objects in the SOAP envelopes takes a lot of time.
So I'd like to retrieve only a "slot" of the data. Is there any EJB3/Hibernate object which could help ?
By myself the only solution that I found is to turn the SLSB into SFSB , add a parameter to the method and return only a slot, not the whole TaskList.
@Stateful
List <TaskList> tasklist;
public List <TaskList> findByRole(String role, int slot){
tasklist = em.createNamedQuery("findByRole")
.setParameter("Role", role)
.getResultList();
// Take a piece of the TaskList
return tasklist;
}What do you think ? any idea on how to improve this ?
Thanks

Scrolling of data with UNSCROLLED header.using struts.Tried a lot my friend

Got the class file fr.improve.struts.taglib.layout.util.FixedHeaderCollection which will be used to solve the problem.But how to use this in struts-layout.tld & in my application,where I am using layout:collection.

I am also attaching the portion of that particular JSP page:

Java NIO - reading large amount of data

Hi,
I have diffuculties of reading large amount of data with SocketChannel (using directAllocated buffer & allocated one). Files greater than 300KB are cut even though I tried write the data into FileChannel.
My Code:
ByteBuffer directBlockBuffer = ByteBuffer.allocateDirect(150000);
buffer = ByteBuffer.allocate(6000000);
out = new     FOS("d:\\msgData.tmp");
fc=out.getFOS().getChannel(); // FileChannel
int fileLength = (int)fc.size();
while (clientChannel.read(directBlockBuffer)>0)
{                              directBlockBuffer.flip()                         buffer.put(directBlockBuffer);
     directBlockBuffer.compact();
//close data file
                                   buffer.flip();
                                   fc.write(buffer);
                                   fc.close();
FOS.close();
// end of code
Any ideas?
Thanks
AST

I don't understand how the "write" result will help read the whole data.
Anyway, I changed the code so the SocketChannel will read in smaller chunks (~8KB) & the FileChannel writes in every read
but the data stream is cut again (to ~5KB no matter what size of file I send).
In the updated code when try to compare socketChannel.read to -1 I got endless loop.
I'm basically trying to write POP3/SMTP server program, this part of code handles attachment that is received by the SocketChannel in one unit (i.e 1+ MB of data, the other SMTP commands/lines are no more than 27 chars and simple to handle).
Therefore I need to be ready to accept large amount of data to the buffer & write it to filechannel. (In the POP3 thread I'm using MappedByteBuffer successfully).
Updated code:
ByteBuffer directBlockBuffer = ByteBuffer.allocateDirect(8192);
while (clientChannel.read   (directBlockBuffer>0&&directBlockBuffer.hasRemaining))
          directBlockBuffer.flip();
          fc.write(directBlockBuffer);
          directBlockBuffer.clear();
     }I think based on API my code is logical (and good for small files) but what about handling bigger files (up to 5MB)?
Thanks,

Error in Generating reports with large amount of data using OBIR

Hi all,
we hve integrated OBIR (Oracle BI Reporting) with OIM (Oracle Identity management) to generate the custom reports. Some of the custom reports contain a large amount of data (approx 80-90K rows with 7-8 columns) and the query of these reports basically use the audit tables and resource form tables primarily. Now when we try to generate the report, it is working fine with HTML where report directly generate on console but the same report when we tried to generate and save in pdf or Excel it gave up with the following error.

With journaling, I have found that my computer is saving a large amount of data, logs of all the changes I make to files; how can I clean up these logs?

With journaling, I have found that my computer is saving a large amount of data, logs of all the changes I make to files; how can I clean up these logs?
For example, in Notes, I have written three notes; however if I click on 'All On My Mac' on the side bar, I see about 10 different versions of each note I make, it saves a version every time I add or delete a sentence.
I also noticed, that when I write an email, Mail saves about 10 or more draft versions before the final is sent.
I understand that all this journaling provides a level of security, and prevents data lost; but I was wondering, is there a function to clean up journal logs once in a while?
Thanks

Are you using Microsoft word? Microsoft thinks the users are idiots. They put up a lot of pointless messages that annoy & worry users. I have seen this message from Microsoft word. It's annoying.
As BDaqua points out...
When you copy information via edit > copy, command + c, edit > cut, or command +x, you place the information on the clipboard. When you paste information, edit > paste or command + v, you copy information from the clipboard to your data file.
If you edit > cut or command + x and you do not paste the information and you quite Word, you could be loosing information. Microsoft is very worried about this. When you quite Word, Microsoft checks if there is information on the clipboard & if so, Microsoft puts out this message.
You should be saving your work more than once a day. I'd save every 5 minutes. command + s does a save.

How do I pause an iCloud restore for app with large amounts of data?

I am using an iPhone app which is holding 10 Gb of data (media files) .
Unfortunately, although all data was backed up, my iPhone 4 was faulty and needed to be replaced with a new handset. On restore, the 10Gb of data takes a very long time to restore over wi-fi. If interrupted (I reached the halfway point during the night) to go to work or take the dog for a walk, I end up of course on 3G for a short period of time.
Next time I am in a wi-fi zone the app is restoring again right from the beginning
How does anyone restore an app with large amounts of data or pause a restore?

You can use classifications but there is no auto feature to archive like that on web apps.
In terms of the blog, Like I have said to everyone that has posted about blog preview images:

Large Amount of Data in JSF

Hello,
I am using the Table Group component for displaying data in my application designed in Java Studio Creator.
I have enabled paging on the component. I use CachedRowSet on the bean for the page for getting the data. This works very well at the moment in my development environment. At the moment I am testing on small amount of data.
I was wondering how does this component perform with very large amounts of data (>75,000 rows). I noticed that there is a button available for users to retrieve all the rows. So I was wondering apart from that instance, when viewing in a paged mode does the component get all the results from the database everytime ?
Which component would be best suited for displaying large amounts of data in a table format?
Thanks In Advance!!

Thanks for your reply. The table control that I use does have paging as a feature and I have enabled it. It still takes time to load the data initially.
I wonder if it is got to do with the logic of paging. How do you specify which set of 20 records to extract from SQL.
Thanks for your help!!

Open Large amount of data

Hi
I have a file on application server in .dat format, it contains large amount of data may be 2 million of records or more, I need to open the file to check the record count, is there any software or any option to open the file, I have tried opening with Notepad, excel .... it gives error..
please let me know
Thanks

Hi,
Try this..
Go to AL11..
Go to the file directory..Then in the file there will be field called length..which is the total length of the file in characters..
If you know the length of a single line..
Divide the length of the file by the length of single line..I believe you will get the number of records..
Thanks,

Bex Report Designer - Large amount of data issue

Hi Experts,
I am trying to execute (on Portal) report made in BEx Report Designer, with about 30 000 pages, and the only thing I am getting is a blank page. Everything works fine at about 3000 pages. Do I need to set something to allow processing such large amount of data?

Hi Sauro,
I have not seen this behavior, but it has been a while since I tried to send an input schedule that large. I think the last time was on a BPC NW 7.0 SP06 system and it worked OK. If you are on a recent support package, then you should search for relevant notes (none come to mind for me, but searching yourself is always a good idea) and if you don't find one then you should open a support message with SAP, with very specific instructions for recreating the problem from a clean input-schedule.
Good luck,
Ethan

Report in Excel format fails for huge amount of data with headers!!

Hi All,
I have developed an oracle report which fetches upto 5000 records.
The requirements is to fetch upto 100000 records.
This report fetches data if the headers are removed. If headers are given its not able to fetch the data.
Have anyone faced this issue??
Any idea to fetch huge amount of data by oracle report in excel format.
Thanks & Regards,
KP.

Hi Manikant,
According to your description, the performance is slow when display huge amount of data with more than 3 measures into powerpivot, so you need the hardware requirements for build a PowerPivot to display huge amount of data with more than 3 measures, right?
PowerPivot benefits from multi-core processors, large memory and storage capacities, and a 64-bit operating system on the client computer.
Based on my experience, large memory, multiprocessor and even
solid state drives are benefit PowerPivot performance. Here is a blog about Memory Considerations about PowerPivot for Excel for you reference.
http://sqlblog.com/blogs/marco_russo/archive/2010/01/26/memory-considerations-about-powerpivot-for-excel.aspx
Besides, you can identify which query was taking the time by using the tracing, please refer to the link below.

Advice needed on how to keep large amounts of data

Hi guys,
Im not sure whats the best way is to make large amounts of data available to my android app on the local device.
For example records of food ingredients, in the 100's?
I have read and successfully created .db's using this tutorial.
http://help.adobe.com/en_US/AIR/1.5/devappsflex/WS5b3ccc516d4fbf351e63e3d118666ade46-7d49. html
However to populate the database I use flash? So this kind of defeats the purpose of it. No point in me shifting a massive array of data from flash to a sql database, when I could access the data direct from the as3 array?
So maybe I could create the .db with an external program? but then how would I include that .db in the apk file and then deploy it to users android device.
Or maybe I create a as3 class with an xml object init and use that as a means of data storage?
Any advice would be appreciated

You can use any means you like to populate your SQLite database, including using external programs, (temporarily) embedding a text file with SQL statements, executing some SQL from AS3 code etc etc.
Once you have populated your db, deploy it with your project:

Looking for ideas for transferring large amounts of data between systems

Hello,
I am looking for ideas based on best practices for transferring Large Amounts of Data in and out of a Netweaver based application.
We have a new system we are developing in Netweaver that will utilize both the Java and ABAP stack, and will require integration with other SAP and 3rd Party Systems. It is a standalone product that doesn't share any form of data store with other systems.
We need to be able to support 10s of millions of records of tabular data coming in and out of our system.
Since we need to integrate with so many different systems, we are planning to use RFC for our primary interface in and out of the system. As it turns out RFC is not good at dealing with this large amount of data being pushed through a single call.
We have considered a number of possible ideas, however we are not very happy with any of them. I would like to see what the community has done in the past to solve problems like this as well as how SAP currently solves this problem in other applications like XI, BI, ERP, etc.

Also I've noticed that if i move / copy things with Dolphin they're substantially slower than if I use cp/mv. But cp/mv works fine for me...
Also run Dolphin from terminal to try and see what's the problem.
Hope that help at least a bit.
Could you explain why Dolphin should be slower? I'm not attacking you, I'm just asking.
Cause I thought that Dolphin is just a „little" wrapper around the cp/mv/cd/ls applications/commands.

Azure Cloud service fails when sent large amount of data

This is the error;
Exception in AZURE Call: An error occurred while receiving the HTTP response to http://xxxx.cloudapp.net/Service1.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being
aborted by the server (possibly due to the service shutting down). See server logs for more details.
Calls with smaller amounts of data work fine. Large amounts of data cause this error.
How can I fix this??

Go to the web.config file, look for the <binding> that is being used for your service, and adjust the various parameters that limit the maximum length of the messages, such as
maxReceivedMessageSize.
http://msdn.microsoft.com/en-us/library/system.servicemodel.basichttpbinding.maxreceivedmessagesize(v=vs.100).aspx
Make sure that you specify a size that is large enough to accomodate the amount of data that you are sending (the default is 64Kb).
Note that even if you set a very large value here, you won't be able to go beyond the maximum request length that is configured in IIS. If I recall correctly, the default limit in IIS is 8 megabytes.
