Large data-centric applications in flex?

Has anyone built a large data-centric application in flex? Are there code examples online?
I have read several articles about how to structure large applications in Flex but as yet have not seen any code examples of how this is achieved in practice.
Any help/links would be greatly appreciated, google hasn't helped me too much.

Tim, here is a bit of feedback about DCD
data management only supporting int as returntype for method createItem ( signature in the docs is createItem(item:myDatatype):int ) seems a bit limitative. We should be able to return the PK datatype or eventually the bean itself. When we are configuring data management the first thing we pick is the primary key so the wizard should be able to validate if the returntype for createItem match de PK. UpdateItem is also problematic, we are assuming that the bean is saved as is, but if we want to update some additional fields server-side, we have to implement some kind of push so the client is updated. The update signature should be updateItem((item: myDatatype):myDatatype or updateItem((item: myDatatype):*
Really don't like the way the services are generated inline and with the endpoint hardcoded. In the past, no endpoint was necessary, even less a full hardcoded one. Since we point it to the services-config, why is there a need to write it in the code? Removing it from the services generated we are still able to run it successfully.
Pagination should support a single count method for multiple paged queries as I explained in another thread. A ER has been made https://bugs.adobe.com/jira/browse/FB-20809.
Lazy-loaded related objects should be supported, the basic support lazy-loading just for the first level (object itself) is quite limitative because complex objects (with many associations ) will take a lot of time to load every single related object. For small projects it can ok, but not for medium / large ones.
The invocation process to service call should be based on events like the rest of the frameworks, flex included, like that we would be able to easily replace the generated code with our own implementation.
Forms generation is quite useful, just think it should be more advanced like enabling formatting and validation process.

How to access internal table data from webdynpro to Flex application.

Hi Connoisseur
The data transfer from Abap WebDeypro to flex island works well. I followed , there is an example from Thomas Jung (by the way as always Great Work) and Karthikeyan Venkatesan (Infosys) but this example covers simple type only.
There is no example with complex types like arrayCollection which handle the transfer of data from flex to WebDynpro.

Flex / Data / Create Application from Database

Hi, I had a question,
When I create an application from a Database (Flex / Data /
Create Application from Database).
Can I modify the coded to convert it into a module?
I have a main application that I would like to load the
Database as a module. I tried replacing the <mx:Application>
Tags to Module but didn't work...
Thanks.

Hi,
no. no answer as yet. Seems to be a connection issue with the
Windows 2003 Server, although all the seetings are correct.
I installed WAMP Server 2.0 locally to see if I can get the
project running locally, and it works fine. I can connect no
problem to the MySQL Database on my local PC. I might just have to
migrate everything over manually once the project is
complete.

Why would I need to use LiveCycle Data Services in a Flex app?

I cannot figure out what additional functionality is provided by using LiveCycle Data Services in my Flex apps. I cannot get a clear understanding of how using LiveCycle Data Services would benefit my applications. Does someone out there use LiveCycle Data Services? If so, what do you do with it in Flex?
Thanks!

- data push for publish/subscribe implementations
User has to do nothing to get updated information. You push it to their machine when new data is available, like Yahoo finance updated quotes.
- data paging
You don't want to display one million rows in your datagrid at once. Get a batch of data, if the user scrolls down, get the next batch, etc.
- server side clustering
One server does not get overloaded. High traffic sites have their large number of concurrent connections managed more efficiently.
- JMS services
JMS is a powerful technology for messaging throughout an application, and LCDS makes it much easier.
- RTMP tunneling
Allows the use of the RTMP protocol in LiveCycle Data Services applications. Makes it easier to traverse firewalls and proxies appropriately that currently prevent direct RTMP client connections to the server.

Data centric check-in

We've had a number of posts here about various issues folks have encountered when trying to use the new data centric features in FB4. I hope we've been able to help work through most of them! I'd like to ask, though, about some general thoughts on this set of features. For those of you who have tried to connect to PHP or ColdFusion or other services, have you been generally successful? Do you find these features helpful? If you've worked with Flex in the past, do you find this approach an improvement? If this is your first time trying Flex, do you find this workflow helpful? And in general, do you feel that you would be able to build your real-world projects with FB4? Any other feedback or suggestions for us?
Thanks!

SOLUTION: Building the Flex 2 FlexStore application in Flex 3

I gave step by step instructions on building the Flex 2 FlexStore application in Flex 3 as a post in the Adobe Flex 3 Cookbook:
http://www.adobe.com/cfusion/communityengine/index.cfm?event=showdetails&productId=2&postI d=15606&loc=en_US
If you don't want to go there, here are the instructions:
1) Download the Adobe FlexStore archive flexstore.zip file.
    - go to http://examples.adobe.com/flex2/inproduct/sdk/flexstore/flexstore.html
    - right-click the application and select View Source
    - click the "Download source (ZIP, 1769K)" link in bottom of the left-side-bar
2) Create a directory "flexstore" somewhere on your harddrive
3) Extract the contents of the flexstore.zip file to the directory flexstore you
   just created. The directory flexstore should now have these top-level contents:
       assets           (directory)
       data             (directory)
       productsView     (directory)
       samples          (directory)
       AC_OETags.js     (file)
       beige.css        (file)
       blue.css         (file)
       build.bat        (file)
       build.sh         (file)
       flexstore.html   (file)
       flexstore.mxml   (file)
       HomeView.mxml    (file)
       main.css         (file)
       ProductsView.mxml    (file)
       README.htmlSupportView.mxml   (file)
4) Launch Flex Builder 3.
5) Select File - Switch Workspace and change the workspace to the directory
   containing the directory "flexstore" you created.
6) After Flex Builder re-launches, create a new Flex Project named "flexstore":
    - ensure the "Web application" radio button is selected for "Application type"
    - click the "Next" button, not the "Finish" button
    - click "Next" again in the "Configure Output" screen
    - ensure the "Main source folder" TextInput has "src" in it
    - ensure the "Main application file" TextInput has "flexstore.mxml" in it
    - click the Finish button
7) Drag all the unzipped files now visible in your Flex Builder "flexstore" project
   folder to the "src" folder Flex Builder created for you, and click "Yes" when
   asked if you want to overwrite the flexstore.mxml file Flex Builder created for you.
8) In Flex Builder, drag the following folders into the "src" folder:
    - assets
    - data
    - productsView
    - samples
9) Right click file build.bat and select Open With - Text Editor.
    - Remove the following line from the file:
         ..\..\bin\mxmlc.exe %OPTS% flexstore.mxml
    - Edit the following lines, replacing "..\..\bin\mxmlc.exe" with the hardcoded
      path to the mxmlc compiler for the Flex 3 SDK, which on my computer is
      "C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\bin\mxmlc.exe". Make sure
      it is enclosed in double-quotes. This will be to build.sh for Mac users.
         BEFORE
         ..\..\bin\mxmlc.exe %OPTS% beige.css
         ..\..\bin\mxmlc.exe %OPTS% blue.css
         AFTER
         "C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\bin\mxmlc.exe" %OPTS% beige.css
         "C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\bin\mxmlc.exe" %OPTS% blue.css
10) Open a DOS window (Terminal in Mac) and change the current directory to the "src"
    directory on the local harddisk, which for me is:
    C:\aaaFlexApps\flexstore\src
11) Execute build.bat (build.sh on Mac).
12) Ensure beige.swf and blue.swf are created in the project "src" directory.
13) Select Project - Clean to rebuild the project.
14) Ensure beige.swf and blue.swf and all the other files from the src
    directory were copied to the bin-debug folder.
15) You should now be able to launch the application.

Reading Large data files from client machine ( urgent)

Hi,
I want to know the best way for reading large data at about 75MB file from client machine and insert to the database.
Can anybody provide sample code for it.
Loading the file should be done at client machine and inserting into the database should be done at server side.
How should i load the file?
How should i transfer this file or data to server ?
How should i insert into the database ?
Thanks in advance.
regards
Kalyan

Like I said before you should be using your application server to serve files >from the server off the filesystem. The database should not store files this big >and should instead just have a reference to this file. I think u have not understood the problem corectly.
I will make it clear.
The requirement is as follows.
This is a j2ee based application.
Application server is oracle application server.
Database is oracle9i
it is thick client (swing based application)
User enters datasource like c:\turkey.data
This turkey.data file contains data

like wise we may have more than 3 lacs rows in it.
We need to read this file and transfer this to the application server. Which are EJBS.
There we read this file each row in file is one row in the database for a table.
Like wise we need to insert 3 lacs records in the database.
We can use Jdbc to insert the data which is not a problem.
Only problem is how to transfer this data to server.
I can do it in one way. This is only a example
I can read all the data in StringBuffer and pass to server.
There again i get the data from StringBuffer and insert into database using jdbc.
This way if u do it. It is performance issue and takes long time to insert into the database.It even may give MemoryOutofBond exception.
just iam looking for the better way of doing this which may get good performace issue.
Hope u have understood the problem.

How to connect oracle data through BlazeDS in flex 4

How to connect oracle data through BlazeDS in flex 4

Hi
               If u want to connect to the database oracle just paste the Ojdbc14.jar file into the lib folder of blazeds project..
                         Normally blazeds distribution version contains blazeds.war file... upload that war file to the tomcat or any other application server..
                      u will get the build path and in lib folder paste the ojdbc14.jar file to connect to the oracle and do u r stuff at server side java ....
                  if this will reslove ur problem please mark as answered..

What is the best approach to return Large data from Stored Procedure ?

no answers to my original post, maybe better luck this time, thanks!
We have a stored proc (Oracle 8i) that:
1) receives some parameters.
2)performs computations which create a large block of data
3) return this data to caller.
compatible with both ASP (using MSDAORA.Oracle), and ColdFusion (using Oracle ODBC driver). This procedure is critical in terms of performance.
I have written this procedure as having an OUT param which is a REF CURSOR to a record containing a LONG. In order to make this work, at the end of the procedure I have to store the working buffer (an internal LONG variable) into a temp table, and then open the cursor as a SELECT from the temp table.
I have tried to open the cursor as a SELECT of the working buffer (from dual) but I get the error "ORA-01460: unimplemented or unreasonable conversion requested"
I suspect this is taking too much time; any tips about the best approach here? is there a resource with REAL examples on returning large data?
If I switch to CLOB, will it speed the process, be compatible with callers, etc ? all references to CLOB I saw use trivial examples.
Thanks for any help,
Yoram Ayalon

Create a new farm in the secondary Data Center at the same patch level with the desired configuration. Replicate the databases using the method of choice (Mirroring, AlwaysOn, etc.). Create a downtime window where you can then attach the databases to the
new farm's Web Application(s)/Service Application(s).

How to handle large data sets?

Hello All,
I am working on a editable form document. It is using a flowing subform with a table. The table may contain up to 50k rows and the generated pdf may even take up to 2-4 Gigs of memory, in some cases adobe reader fails and "gives up" opening these large data sets.
Any suggestions?

Ok, that is good to know. We will be working in roughly the same order
of magnitude. The final application will run on a well equipped server,
unfortunately my development machine is not as powerful so I can't
really test that.

We have a very hierarchical model. I still wonder to what extent EMF and
QVTo at least try to let go of objects which are not needed anymore and
allow them to be garbage collected?
> Is the GC overhead limit not tied to the heap space limits of the JVM?
Apparently not, quoting
http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html:
"The concurrent collector will throw an OutOfMemoryError if too much
time is being spent in garbage collection: if more than 98% of the total
time is spent in garbage collection and less than 2% of the heap is
recovered, an OutOfMemoryError will be thrown. This feature is designed
to prevent applications from running for an extended period of time
while making little or no progress because the heap is too small. If
necessary, this feature can be disabled by adding the option
-XX:-UseGCOverheadLimit to the command line."
I will experiment a little bit with different GC's, namely the parallel GC.

Exe on Cloud Service crashing for slightly larger data

Hi,
I have launched a C++ exe in cloud service which is working fine for smaller data and crashing as we provide slightly larger data which is taking hardly 5 minutes to solve when running locally.
Can anyone suggest what could be the issue???
Thank you.

Hi ,
It seems that this is the executionTimeout error. Please try to change "executionTimeout" value.
<system.web>
<httpRuntime executionTimeout="600" />
</system.web>
>>Also, can you explain the parallel approach that we can use to handle data on azure role. I am using a single web role in my application.
I am not familiar with C++, but I think you could use the concurrent or multiple threads on your projects:
http://stackoverflow.com/questions/218786/concurrent-programming-c
And I found some resource about how to deploy exe on azure, please refer to it:
http://www.codeproject.com/Articles/331425/Running-an-EXE-in-a-WebRole-on-Windows-Azure
Another way, You also used the startup script to start and run the EXE file, you could see this blog,

Error deploying data tier application to SQL Azure at "Registering metadata for database" step ... should I care?

I'd like to move an on-premesis SQL Server Database to SQL Azure. I've used SQL Mgmt Studio to Extract Data Tier Application and save my db as a dacpac file. Now I'm connected to my Azure server and I've chosen to Deploy Data Tier Application. I select my
dacpac and the deploy starts but then on the last step "Registering metadata for database" it times out. I've tried it a couple of times and each time the deployed database is there and appears to be fully populated, but I'm not sure if I can ignore
that error and continue. What is supposed to happen in that step, and should I expect it to fail when deploying to SQL Azure?
I'm following the steps here http://msdn.microsoft.com/en-us/library/hh694043.aspx in the Using Migration Tools > Data-tier Application DAC Package section, except that to deploy there's no SQL Mgmt Studio > Object Explorer [server]
> Management >"Data Tier Applications" node, so I'm deploying by right-clicking on the server name and choosing "Deploy Data-tier Application".
My (total) guess here is that it's deployed the database fine and it's doing whatever magic happens when you register a data tier application, except that it's not working for SQL Azure.
I'm running against a server created for the new Azure service tiers, not against a Web/Business edition server.
The full details of error I get are below.
thanks,
Rory

Hello,
The registration process creates a DAC definition that defines the objects in the database, and register the DAC definition in the master system database in Windows Azure SQL Database.
Based on the error message, there is timeout error when connect to SQL Database. Did you deploy a large database? When move large data to Azure SQL Database, it is recommended to use SQL Server Integration Services (SSIS) and BCP utility.
Or you can try to create a client application with the Data-Tier Application Framework (DACFx) client tool to import database and handle connection loss it by re-establish the connection.
