Facing a problem when running a geoprocessing service

MuralidharMoka — Tue, 15 Nov 2011 23:01:07 GMT

I am facing a problem when running a Geoprocessing service.

In a nut shell, the whole process is this,

1. We select two graphics from a featurelayer and save it to another Featurelayer1. To these graphics
     we add and attribute PRIM_TRANS_ID

2.The Geoprocessing service will now be kicked . The Geoprocessing service will merge these above two graphics and creates a resulting graphic and saves to another layer say FeatureLayer2 with the same PRIM_TRANS_ID.

3.We try to query the Featurelayer2 and get the graphic.

The problem is the First steps happens sucessfully. The graphics are saved to Featurelayer1.
The Geoprocessing service says it succeeded and gives the job id, but does not create the final graphic in Featurelayer2. We get a 0 Count in the Featurelayer2.

Say if we run the Geoprocessing service once again with the same Trans_Id.Now the graphics get created. It looks like we are kicking the Geoprocessing service even before the graphics are created in the Featurelayer1. But we saw the the grapics are already before starting the geoprocessing task(We set a brek point and observed the graphics are there)

We just wanted to know what is happening. why does the resultant layer gets the graphic when we re run it. But not the first time.

private string PRIM_TRANS_ID = null; //global

             public MainPage()
               {
                  DissolveFeature = MyMap.Layers["UtilityDissolveFeature"] as FeatureLayer; //this is nothing but Featurelayer1
                  DissolveFeature.EndSaveEdits += new EventHandler<EndEditEventArgs>(DissolveFeature_EndSaveEdits);

                }

private void btnProcessTask_Click(object sender, RoutedEventArgs e)
        {
            //after selectin the graphics this is called
            ProcessGeoProcessingTask();
        }

        private void ProcessGeoProcessingTask()
        {
            //STEP1:Get the selected Graphic and create a Copy
            PRIM_TRANS_ID = Guid.NewGuid().ToString();
            foreach (Graphic g in countylayer.SelectedGraphics)
            {
                if (g == null)
                {
                    MessageBox.Show("Graphic is Null select County Layer");
                    return;
                }
                Graphic countyGrpahic = g;
                Graphic copyGraphic = new Graphic()
                {
                    Geometry = countyGrpahic.Geometry
                };
                //add a Guid attribute

                copyGraphic.Attributes.Add("PRIM_TRANS_ID", PRIM_TRANS_ID);
                DissolveFeature.Graphics.Add(copyGraphic);
            }
            DissolveFeature.SaveEdits();

Give a closer look on information, first time execution displays two warnings..hence there is something wrong in code. Debug the GP tools and see the issue.

Thanks for looking into this. I dont know what GPTools are. Can you please explain me more.
I am still unable to figure this out.
Thanks

I assumed that Geoprocessing call which you make is custom call. i.e. You can created Geoprocessing model and published as Geoprocessing tool (GP Tool) and accessing the same in client application.

I thought "poly_dissolve_model" is your custom program designed for dissolve operation based on condition. Let me know if my assumption is correct

You are right.The Poly_dissolve_model is the Geoprocessing service we wrote which will merget two graphics and creates a new graphic which we are trying to access. But we dont get the graphic back.

Again simply this is what we are doing
1.We have a FeatureLayer( To this layer we add a two or three graphics with an attribute PRIM_TRANS_ID)
2.We have a geoprocessing service-GP tool( this will take those graphics and merges it and creates a new graphic )
3.We have an final featurelayer2 (Result layer where we final graphic merged graphic gets created)

Step1: done in ProcessGeoProcessingTask()
Step2: done in DissolveFeature_EndSaveEdits //Geoprocessing done here
Setp3: geoprocessorTask_JobCompleted

We have other Geoprocessing services also which we are using and we have problems like.
If the client runs the Geoprocessing service, it works the first time and then it starts failing
2nd, 3rd times and so on.
After some time if we try like after 1hr.It again works for the first times and fails.
When this happens we start our geoprocessing service to trouble shoot, some times it works and some times it doesnt. We are yet unable to identify why geoprocessing services are not working properly. Let us know if our code should take care of any thing once we start or end a Geoprocessing service.

I gave code in txt file.
