描述
删除现有地图影像图层缓存(包括磁盘上的所有关联文件)。
使用方法
由于这是一种不可恢复的操作,因此只有确定不再使用缓存时,方可执行此项操作。如果要删除切片但保留缓存文件夹结构和切片方案,请使用管理地图服务器缓存切片工具,并将更新模式设置为 DELETE_TILES。
此工具运行后,将重新启动服务。
语法
arcpy.server.DeleteMapServerCache(input_service, {num_of_caching_service_instances})
参数 | 说明 | 数据类型 |
input_service | 待删除缓存切片所属的地图影像图层。 | Image Service; MapServer |
num_of_caching_service_instances (可选) | 定义用于更新/生成切片的实例数。该参数的值将设置为无限 (-1),且无法进行修改。 | Long |
派生输出
名称 | 说明 | 数据类型 |
out_job_url | 输出 URL。 | 字符串 |
代码示例
在本例中,将使用 DeleteMapServerCache 删除名为 Rainfall 的地图服务的一个缓存。
# Name: DeleteMapServerCache.py
# Description: The following stand-alone script demonstrates how to delete map server cache
# tiles if the corresponding cache schema or tiles has been created
# 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 variables for mapservice 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
numOfCachingServiceInstances = 2
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')
# To Recreate all the tiles for the default number of scales generated
try:
starttime = time.clock()
result = arcpy.DeleteMapServerCache_server(inputService,
numOfCachingServiceInstances)
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("Deleted cache tiles & schema for mapservice " + serviceName + \
"\n in " + str(elapsedtime) + " sec \n on " + arg2)
except Exception as e:
# If an error occurred, print line number and error message
tb = sys.exc_info()[2]
report.write("Failed at \n" "Line %i" % tb.tb_lineno)
report.write(str(e))
print("Deleted Map server Cache Tiles ")
report.close()
