描述

在现有已缓存地图或影像服务中更新比例级别。使用此工具可添加新比例或从缓存中删除现有比例。

代码示例

ManageMapServerCacheScales 示例（独立脚本）

在本例中，将地图缓存切片方案修改为包含四个比例。

# 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()
    
print "Updated Map server Cache scales "
