Manage Map Server Cache Scales (Server)
Summary
Updates the scale levels in an existing cached map service. Use this tool to add new scales or delete existing scales from a map cache.
Usage
-
If you remove scales from an existing cache, it will permanently delete all existing cached tiles within that level of detail.
Syntax
| Parameter | Explanation | Data Type |
server_name |
The ArcGIS Server machine hosting the service from which you want to remove cache scales. | String |
object_name |
The name of the map service from which you want to remove cache scales. | String |
levels [levels,...] |
The scale values to be included in the updated tiling scheme.  Caution:You must specify existing scale values if you want to keep them. Any existing scale levels you do not specify in this tool will be permanently deleted. For example, if you have four existing scales and you wish to add two scales, make sure your final list has a total of six scales. | Value Table |
Code Sample
This example modifies a map cache tiling scheme to contain four scales.
