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 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 or Portal for ArcGIS.

• 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 parameter (manage_mode in Python) to REPORT_BUNDLE_STATUS. The report is stored in a new file geodatabase named Status.gdb, specifically within a feature class named TaskStatus.

  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

ManageMapServerCacheStatus(input_service, manage_mode, {scales}, {num_of_caching_service_instances}, {report_folder}, {area_of_interest}, {report_extent})

Parameter	Explanation	Data Type
input_service	The map image layer for which the cache status will be modified.. You can choose it by browsing to the desired service in Portal or you can drag and drop a web tile layer from the Catalog pane Portal tab to supply this parameter.	Image Service; MapServer
manage_mode	DELETE_CACHE_STATUS —Deletes the status information used by the server. REBUILD_CACHE_STATUS —Deletes, then rebuilds the status information used by the server. REPORT_BUNDLE_STATUS —Creates status information in a new file geodatabase named Status.gdb in a folder you specify in the Output Folder parameter. This option is used when you want to create a custom status report for a particular area of interest or set of scales.	String
scales [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
num_of_caching_service_instances (Optional)	Defines the number of instances that will be used to update/generate the tiles. The value for this parameter is set to unlimited (-1) and cannot be modified.	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.	Folder
area_of_interest (Optional)	An area of interest (polygon) that determines what geography the status report will cover. This parameter is only applicable when building a custom status using the REPORT_BUNDLE_STATUS option.	Feature Set
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

Derived Output

Name	Explanation	Data Type
output_folder	The output service URL.	String

Code sample

ManageMapServerCacheStatus example (stand-alone script)

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[]"
