Geoprocessing service with REST and Web

[JanicePoehlman]

When I use the REST endpoint to access my geoprocessing service I can successfully run a tool (export, et al) on all my files.  When I use the web browser to access the same tool & geoprocessing service I get about a 50% success rate due to a time out error.

I suspect a time out setting somewhere in the JavaScript/Web interaction with AGS.  Has anyone else run into this issue as well and know where this parameter might be set?

The REST web.config file includes a <httpRuntime executionTimout="1200' />
The GP service parameters are default at 600s max time a client can use a service, 60s max time client will wait for service, 1800s max time idle instance kept running.

The files that I am processing should take just over 2 minutes of process time, based on testing and like-sized files.  All files run successfully at the REST endpoint --where is the (likely 120s) setting that I can change on the web end to get my larger files to process??

Thank you.

Synchronous GP task are ideal for short running tasks. Since this task takes ~ 2 minutes, can you consider publishing this tool as an Asynchronous GP Service.

[JanicePoehlman]

Per your suggestion, Ravi, I'll create a separate GP service for this tool and set it up as asynchronous.  I'll serve it in our development environment.  Thanks, I'll report back on how it performs.

Actually, I solved the timeout of exported large file sizes by changing the timeouts of a number of configuration files, which didn't affect application performance.  The configurations that I changed were:

web.config at REST api
timeout = 1200

NAM gateway
gateway timeout to 1200

web.config for application timeout
timeout value = 1200000
execution timeout = 1200000
