Acessing ElectricSources through ArcFM server giving error. Following is the code sniplet, same works fine if implement in desktop

Code to execute on FeederManager Find button click

//get ServerContext from MapService

//Get IMap from ServerContext
IMapServer mapser = mapResource.MapServer;

}

eSource = new ElectricSources(pGeomNet);
}

Miner.Interop.IMMFeederSource fSource = eSource.AvailableFeeders["EV-01"];

IMMFeederSpace feederSpace = eSource.FeederSpace;

IPropertySet properties = new ESRI.ArcGIS.esriSystem.PropertySet();
properties.SetProperty("SearchType",0); // Convert.ToInt32 (drListFeeder.SelectedItem.Value));
properties.SetProperty("Phase", -1); //drEnergised.SelectedItem.Value);
properties.SetProperty("Feeders", fSource);
properties.SetProperty("LinesOnly", null);
properties.SetProperty("AutoZoom", null);
properties.SetProperty("FeederSpace",feederSpace);
properties.SetProperty("SelectableLayersOnly", null);

IMMSearchConfiguration config = new SearchConfiguration();
config.SearchParameters = properties;

MMSearchControl serchContol=new MMSearchControl();
IMMSearchResults result = fSearch.Find(config, serchContol);




Error while getting fSource
eSource evaluation fails with following exception
{Miner.Geodatabase.Integration.ElectricSources}
AvailableFeeders: Function evaluation timed out.
AvailableSubstations: Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.

It looks like you may be running into a timeout issue of some sort. Assuming you're using 9.3.1, I recommend checking the following ArcFM Help Documentation to tweak your timeout settings: Configuring ArcFM Solution > ArcFM Server > ArcFM Viewer for ArcGIS Server > Optional Configurations. There are a few sub-categories in there with articles on adjusting various timeouts.

Also, I recommend testing the functionality of this button against small networks to verify functionality. Because a Server application is a web application, it doesn't like to deal with 30,000+ features and can take a very, very long time to do so (unlike Desktop); that is likely the root of the issue here.

Thanks Denton for reply, but problem still not resolved

The same exception occurs even when we test the application only with one feeder left in the map service and increase time-outs in the configuration settings of the application for AJAX, sessionState, JavaScript and Network time-outs.

What we noticed here is the exception comes less than 20 Sec. We tested with the feeder data of around 1000 features also.

We had run the downstream trace on one of the biggeste feeder and it got executed successfuly in web but while accessing ElectricSources we are getting the error. NOt able to understand why it is happening

What sort of work have you done thus far in terms of debugging? It would be really helpful to know what line is choking the tool. I recommend inserting some debug text, or stepping through the code one line at a time to find out exactly where it crashes. That might give some additional insight as to what is happening.

As an additional note, I searched the ArcFM Server Developer Help Guide, and didn't find mention of IMMFeederSource, or FeederSource. Since the error message in the Miner Event Log seems to indicate that the error occurs getting fSource, I would say that if, during your debugging, you find that the line which causes the tool to crash is:
Miner.Interop.IMMFeederSource fSource = ....
then, the problem is because that isn't available in Server. That conclusion is supported by the fact that your code works as-is in a desktop environment.

Let me know how the debugging goes.

We able to get the electric sources now with the code given below but not able to run the feeder manager search, code attached and also attaching the screenshots of debugger

After a chat with a developer, it is likely that the problem here is that a map is needed for Feeder Manager to do its stuff. In a Desktop or Engine environment, we rely on grabbing that focus map from a runtime environment. But, unfortunately, that's not available to us in Server - this is why you're basically getting a null object error; the map is null.
