System.OutOfMemoryException while fetching 100000 records over WCF 10 times

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :WCF
 
Hi, I am testing bulk data transfer over WCF service and my scenario is as follows. WCF service contains method GetData which fetch data from DB(100000 records), fills datatable, converts this datatable to array of string and returns this array of string This service is hosted in the windows app programmatically (No config file) AT the client side, proxy object is created using channelfactory In a button click event, simply call to GetData method and holds it into string array, then covert this array back to datatable and assign this datatable to grid. I have written custom class to convert datatable to string array and vice versa which will be available on both sides. Now when I click button to execute this operation, then 9 times it works perfectly fine but on the 10th click it gives System.OutOfMemoryException in custom class method which coverts array to datatable and each time error is on different line. I am unable to find solution for it. I have tried setting all used objects to nothing wherever possible but the error still persists. Can anyone help me on this. Regards, PrabiI can be still better.

SQL and Merge replication -> Number of records limited to 100000?

  

Hi all,

I´ve a publication in a server with SQL 2008 Enterprise.

I´ve a  client with SQL 2008 Express. Here i´ve a clean database.

There's a table in the server with 569856 records and it´s included in a publication with no filters.

I create a Merge subscription, but when it finished the client table has only 100000 records.

Is there a limit in SQL 2008  Express?

Thanks.

An error occured during local report processing. Exception of type 'System.OutOfMemoryException' W

  

I've been getting this error, randomly when previewing two reports.

It does not seem to be based on report complexity, size, subreports etc. When
reports are deployed to server, they all run fine. I just get the out of memory error locally.

1. I have one version with 2 datasets, and a number of matrix, table and list data regions.
2. I have a second version with only one table data region.
3. There is no custom code, variables, prompts or generally anything other than basic
formatting in the report.
4. Both reports are based on the same SQL table.

I can seem to run the two reports (both based on same SQL table) a few times, and
then they start giving the out of memory error.

I can open other other reports and they preview fine locally.

What I've tried so far to no avail:

1. Deleted the downloaded data before refreshing the two reports.
2. Tried building the two reports before running.
3. Tried changing the process priority to high for devenv.exe.
4. Removed filters in the reports.
5. Changed the physical order of the underlying table.
6. Closed the reports and then re-opened them.
7. Close Visual Studio and Re-Open. This seems to work for a while and then the two
reports start giving the error messages again.

System Development Life Cycle

  
The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), the fountain model and the spiral model. Mostly, several models are combined into some sort of hybrid methodology
