Problem: A remote process, created with the Generate to Coverage Wizard, never finishes execution

Description

Using the Geoprocessing Server to process a job created with the Generate to Coverage Wizard never finishes processing.

Cause

A remote geoprocessing job, from the Generate to Coverage Wizard, may never complete if the input generate file is defined using a Universal Naming Convention (UNC) path.

There is a known problem with using UNC paths in the generate module.

Solution or Workaround

  1. Copy the generate file onto the Geoprocessing Server.
  2. Populate the Generate to Coverage Wizard by selecting the generate file stored on the Geoprocessing Server (Step 1).
  3. Click the 'Save to AML' button on the last panel of the Wizard. Give an appropriate name and location. Close the Wizard; do not execute it.
  4. Open the AML file with a text editor. The contents will be similar to the code sample below, where gpsComputer is the name of the geoprocessing machine:

    Code:
    /* Begin: Generate to Coverage Wizard
    /* Aml script created with ArcToolBox for tool: Generate to Coverage Wizard
    /* Editing this file may make it unreadable to the ArcToolbox
    Precision Single Highest
    Precision DOUBLE
    Generate d:\wksp\outputcov
    Input \\gpsComputer\temp\file.gen
    Polygons
    quit
    /* End: Generate to Coverage Wizard

  5. Replace the UNC path to the input file with the equivalent local path. Change the output coverage local path to a UNC path where the geoprocessing server can write the results.

    Code:
    /* Begin: Generate to Coverage Wizard
    /* Aml script created with ArcToolBox for tool: Generate to Coverage Wizard
    /* Editing this file may make it unreadable to the ArcToolbox
    Precision Single Highest
    Precision DOUBLE
    Generate \\mymachine\wksp\outputcov
    Input c:\temp\file.gen
    Polygons
    quit
    /* End: Generate to Coverage Wizard

  6. Open the ArcToolbox Run Geoprocessing AML tool. Load the AML script from step 5 and run it.
