Posted By:      Posted Date: August 28, 2010    Points: 0   Category :.NET Framework
I have a windows client application which would be used many users. This application submit requests to run a workflow (note that this is not a WWF or WCF service, its a class library thats gonna do some processing). What would be the best approach to code this? Would processing each request on a separate thread be a correct way? I am a newbie at this. PLease help. Thanks!

ewa refresh succeeds, but fails with multiple concurrent requests


we have about 30 excel web access web parts spread across 6 pages.  they all connect to ssas using windows authentication, and they all work fine.

we have a user that wants to set his browser to open the 6 pages on 6 tabs as his "home" tab arrangement.  so when he launches his browser, all 6 pages open simultaneously.  all of the ewa web parts give the error:

"An error has occurred trying to perform the requested action. Please try again."

when i check the logs, i don't see any exceptions.  i just see the messages below. i have set the "maximum concurrent queries per session" for the trusted file location to 1000.  i've tried changing various other settings in the excel services config.  i have no idea what else to try based on this information:



10/03/2010 19:19:30.98 	w3wp.exe (0x0AB0)            	0x1160	Excel Services Application  	Excel Calculation Services  	6v6o	Assert 	(0): location: (0) condition:  StackTrace: at Microsoft.Office.Server.Native.dll: (sig=35b73ac2-5d4b-41d9-b101-286fc6f53dd5|2|microsoft.office.server.native.pdb, offset=203FD) at Microsoft.Office.Server.Native.dll: (offset=20959) at xlsrv.dll: (sig=ae42e7c5-84bd-429e-bec2-0fdd9dad3ee7|2|xlsrv.pdb, offset=4C58E8) at xlsrv.dll: (offset=33

Concurrent requests WCF + net.tcp



we are using the WCF service and hosted using a console application, now we are using LoadRunner and hitting it concurrently

Where giving 50 hits at a time few requests (26) gets completed successfully and remaining gives error TCP error code 10061: No connection could be made because the target machine actively refused it.

Any help is appreciated.

SDLC Approach or Software Development Life Cycle

SDLC process stats from conception to completion of any software project. According to this approach the software development team is responsible for the whole project development life cycle. After doing SRS and requirements analysis; developers follow different models of Software development Life Cycle (SDLC) available, while the most common model is SDLC waterfall model. They divide project in different stages & phases and the output of each stage or phase becomes the input for next stage.
