Manage Map Server Cache Scales

Summary

Updates the scale levels in an existing cached map or image service. Use this tool to add new scales or delete existing scales from a cache.

Usage

  • If you remove scales from an existing cache, it will permanently delete all existing cached tiles within that level of detail.

Syntax

ManageMapServerCacheScales(input_service, scales)
ParameterExplanationData Type
input_service

The map or image service for which you want to add or remove cache scales.

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. Change the backslashes to forward slashes, for example, GIS Servers/arcgis on MYSERVER (admin)/USA.MapServer.

Code sample

ManageMapServerCacheScales example (stand-alone script)

This example modifies a map cache tiling scheme to contain four scales.

# Name: ManageMapServerCacheScales.py
# Description: The following stand-alone script demonstrates how to add/delete
#               MapServer cache scales for a map service with an existing schema
#               
# Requirements: os, sys, time & 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
import arcpy
from arcpy import env
import os, sys, time, datetime, traceback, string

# Set environment settings
env.workspace = "C:/data"

# List of input variables for map service properties
connectionFile = r"C:\Users\<username>\AppData\Roaming\ESRI\Desktop10.1\ArcCatalog"
server = "arcgis on MyServer_6080 (publisher)"
serviceName = "Rainfall.MapServer"
inputService = connectionFile + "\\" + server + "\\" + serviceName
scales = "250000;125000;64000;5250"

currentTime= datetime.datetime.now()
arg1 = currentTime.strftime("%H-%M")
arg2 = currentTime.strftime("%Y-%m-%d %H:%M")
file = 'C:/data/report_%s.txt' % arg1

# print results of the script to a report
report = open(file,'w')


try:
    starttime = time.clock()
    result = arcpy.ManageMapServerCacheScales_server(inputService, scales) 
    finishtime = time.clock()
    elapsedtime = finishtime - starttime

    #print messages to a file
    while result.status < 4:
        time.sleep(0.2)
    resultValue = result.getMessages()
    report.write ("completed " + str(resultValue))
    
    print "Updated the number of cache scales successfully for " + serviceName
    " in " + str(elapsedtime) + " sec \n on " + arg2

except Exception, e:
    # If an error occurred, print line number and error message
    tb = sys.exc_info()[2]
    report.write("Failed at step 1 \n" "Line %i" % tb.tb_lineno)
    report.write(e.message)
report.close()
