Manage Map Server Cache Status (Server)
Summary
Manages internal data kept by the server about the built tiles in a map or image service cache.
Usage
- This tool can remove or rebuild the cache completion status information reported in ArcMap or ArcGIS Server Manager.
This tool is useful for rebuilding the cache status after you manually copy tiles into the cache directory or build tiles on demand.
This tool is the only way to build a status for a cache created with a previous release of ArcGIS Server.
Rather than creating a status for the entire cache, you can alternatively use this tool to create status reports for custom areas of interest and scale levels. You do this by setting the Manage Mode (manage_mode) parameter to REPORT_BUNDLE_STATUS. The report is stored in a new file geodatabase named Status.gdb, specifically within a feature class named TaskStatus that you can display and view in ArcMap.
Note that your cache directory also contains a Status.gdb that pertains to the entire cache and is updated when you use the other Manage Mode options for this tool. You cannot substitute a custom Status.gdb in this location.
Syntax
| Parameter | Explanation | Data Type |
input_service | The map or image service for which the status will be modified. This is a string containing both the server and service information. To see how to construct this string, open ArcCatalog, select your service in the Catalog tree, and note the text in the Location toolbar. Then change the backslashes to forward slashes, for example, GIS Servers/arcgis on MYSERVER (admin)/USA.MapServer. | String |
scales (Optional) |
The scale levels for which the status will be modified. This parameter is only applicable when building a custom status using the REPORT_BUNDLE_STATUS option for the manage_mode parameter. | Double |
manage_mode |
| String |
num_of_caching_service_instances (Optional) |
The total number of instances of the System/CachingTools service that you want to dedicate toward running this tool. You can increase the maximum number of instances per machine of the System/CachingTools service using the Service Editor window available through an administrative connection to ArcGIS Server. Ensure your server machines can support the chosen number of instances. This tool uses three instances by default, if that many are available. Using a larger number of instances with this tool may cause the operation to slow down. | Long |
report_folder (Optional) |
Output folder for the Status.gdb. This parameter is only applicable when building a custom status using the REPORT_BUNDLE_STATUS option. The account running ArcGIS for Desktop needs write access to this folder. This folder must not already have a Status.gdb in it. | Folder |
report_extent (Optional) |
A rectangular extent defining the area for which the status will be built. This parameter is only applicable when building a custom status using the REPORT_BUNDLE_STATUS option. Note that the Area Of Interest parameter allows you to specify an area of interest that is nonrectangular. | Extent |
area_of_interest (Optional) |
An area of interest (polygon) that determines what geography the status report will cover. This can be a feature class, or it can be a feature that you interactively define in ArcMap. This parameter is only applicable when building a custom status using the REPORT_BUNDLE_STATUS option. | Feature Set |
Code Sample
ManageMapServerCacheStatus example
Delete the status information for a cache.
# Name: ManageMapServerCacheStatus.py
# Description: The following stand-alone script demonstrates how to delete
# Status of cache using ManageMapServerCachStatus tool
# Requirements: os, sys, time and traceback modules
# Any line that begins with a pound sign is a comment and will not be executed
# Empty quotes take the default value.
# To accept arguments from the command line replace values of variables to
# "sys.argv[]"
# Import system modules
