Wish you all very Happy GIS day…!!!!
Today November 14 has been celebrated as GIS DAY, the annual salute to geospatial technology and its power to transform and better our lives. I wish all my fellow colleagues and all others who work in geospatial technology a very happy day.
I have been facing one of the error in our sliverlight application (using ESRI 2.4 API) which calls our custom geoprocessing (using ArcGIS 10 SP4) tasks to execute huge huge process which last for more than 10 min (avg), but before that client gets timed out. This is very much annoying and lot of users complained about this. In Fiddler we are getting timeout exception in stack trace.
Server Error in ‘/ArcGIS/rest’ Application.
Request timed out. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Request timed out.
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
[HttpException (0x80004005): Request timed out.]
After going through all ESRI/Microsoft forums. I have increased a) Increased executiontime out value in web.config b) Increased GP Tool client timeout values , but nothing worked and application fails with same mesage. The REST tool is working fine when this executed from browser and URL is available and correct. This is an POST request FYI.
We have trying a lot on this but did not get any clue. After lot of research, we have checked restlog.txt (under C:\inetpub\wwwroot\ArcGIS\rest) folder and found below log message
Log Entry : 11/8/2012 6:06:40 AM
ERROR:Thread was being aborted. :: at ESRI.ArcGIS.REST.GPServer.SubmitGPTaskJsonFormatter.Init()
at ESRI.ArcGIS.REST.RestHttpHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext context)
so we narrowed down that this request sent to server was aborted after some time because of some reasons. We have checked all time out property in IIS/ASP.NET but could not succeed. This becomes complex now. This entire effort consumed lot of effort because custom tool will run for 30 min and then it will fail, so we need lot of time to change one parameter and test from the client application. We kept on trying on this.
The process got terminated so that it couldn’t do logging in ArcGIS Server level so that exception didn’t happen inside of the service call handling. This means that the query handling thread got terminated from ASP.NET / IIS level. We have got some clue from ESRI Forum as well.
We have added <httpRuntime executionTimeout=”7200″/> in Web.config file under C:\inetpub\wwwroot\ArcGIS\rest folder and our issues are resolved. This value extended the execution time out and process ran smoothly and client application displayed the results as well.
Finally we learnt from this link “Since ASP.NET timeout is internally implemented so that the check fires in every 15 seconds. When using the default value, the ASP.NET aborts the query thread in 110 – 125 seconds”
Thanks to ESRI Forum and Antti Kajanus . Issue has been resolved successfully.
I believe ESRI will provide detailed stack trace on their REST API calls, I assume this was in their list.
Finally – Wish you a All very Happy Diwali!!!!

Finally after a long wait, ESRI sliverlight 3.0 has been released. I am very much looking for this mainly for one reason i.e support for Microsoft Sliverlight 5.0. Most of our client groups have updated with Microsoft Sliverlight 5.0 but our application supports only version 4.0 hence waiting for this release.
There are many features available in latest version, but feature which really impressed me and which I am looking for is below
1. Support for datum transformation for handling projection system changes from client
2. Support for geometry with Z and M values by which order of rings in polygons can be identified.
3. Enhance query options with order by results and generate statistics
4. Beautiful print task , which has been waiting for a long time. Excellent ESRI.
5. Ablity to change layer rendering /order or add layers on fly in map services are the excellent.
Please click here to read full updates and enhancements.
Really excited to work with the latest API and upgrade our applications.
I am getting lot of emails about ESRI web API concepts/basics and how to use them, how it differs from other API’s comparisons etc… Many students asking me for training materials and tutorials/getting started materials.

Please write me for any questions/clarifications. Hope this helps lot.
I am just going through the ESRI and learning what are all new features available in ArcGIS 10.1. This post talks about the important changes which I have noticed and interests on the new version. There are many more..
1. New look for ArcGIS. This looks really cool at least to me , I like different colors and new fonts.
2. ArcGIS 10.1 no longer supports VBA environment. So folks be prepared move out of VBA tools. I have seen lot of data development company uses VBA as primary language for their work. If so, its time to change.
3. ArcGIS 10.0 is the last release that the ArcObjects SDK for Microsoft .NET will support Visual Studio 2008. ESRI constantly supports MS.
4. Major Change :
ArcGIS Server 10.0 is the last release with support for 32‐bit operating systems. The next
release of ArcGIS Server (10.1) will run natively as a 64‐bit application, requiring 64‐bit operating
systems. [Added 8/18/2011] This includes the ArcSDE technology component of ArcGIS Server
known as the ArcSDE application server.
We have faced enough problems with 32bit/64 bit platforms on ArcGIS server. Thanks ESRI 🙂
5. ArcGIS server 10 is last release of using MXD. From 10.1 , all are MSD’s. This is an interesting change. Need to check how compatablity of MSD’s with Web API’s.
6. Cool feature: Installation of ArcGIS server made easier – No SOM and SOC’s
With the new architecture of of ArcGIS Server 10.1 , accounts are no longer required for ArcSOM and ArcSOC processes. SOM and SOC’s are no longer used. Instead one account is used to run the ArcGIS Server process . The rest of the configuration is done through the updated manager. This is very good stuff. One who installs and maintains Server know how to difficult with all these accounts .
7. ArcGIS Server 10.1 will be the last planned release for the ArcGIS Server Web ADFs, No DCOM support, web editing functionality of default Web ADF will no longer be supported. Custom developed applications from business partners and users using fine grained ArcObjects through DCOM will not be supported. We are already started using Geoprocessing Framework and SOE;s
8. AUTOMATIC REST CACHE clearing . This is MUST required
