在 DB2 中编写 ArcSDE 地理数据库升级脚本

可以修改和使用在本主题中提供的某个 Python 脚本来连接和升级 ArcSDE 地理数据库。

前面两个脚本使用现有的 ArcSDE 连接文件来连接和升级地理数据库。

第二个脚本显示如何能够在用于升级地理数据库的相同脚本中提供连接信息。此脚本在无法访问 ArcGIS Desktop 时特别有用;您可在已安装 ArcGIS Engine(含 Geodatabase Update 扩展模块)或 ArcGIS Server Enterprise(标准版或高级版)的计算机上运行 Python 脚本,并提供连接信息和升级地理数据库。

无论是使用现有的 ArcSDE 连接文件还是通过脚本中的参数,您与地理数据库建立的连接都是直连。用于运行脚本的计算机上必须有以下内容:

请确保升级之前已经阅读和执行过升级 DB2 中的地理数据库的准备工作中的步骤。

步骤:
  1. 将这些示例脚本之一复制到 ArcGIS Desktop 中的 Python 窗口或任何 Python IDE(如 PythonWin 或 WING)。根据需要更改任意变量值,以与您的站点信息相匹配。
    • 如果现有 ArcSDE 连接文件使用直连并以 ArcSDE 管理员的身份进行连接,则请根据不同的操作系统来复制和修改以下脚本之一:
      # Name: upgradesdegdb_example.py
      # Description: Connect from a Windows computer 
      # with an existing ArcSDE connection file 
      # and upgrade an ArcSDE for DB2 geodatabase
      # Author: Esri
      
      # Import arcpy module
      import arcpy
       
      # Local variables:
      Output_Workspace = "C:\\ArcGIS\connection_files\<Connection file>"
      Default_gdb = "C:\\ArcGIS\connection_files\<Connection file>"
      
      # Process: Upgrade Geodatabase
      arcpy.UpgradeGDB_management(<Connection file>, "PREREQUISITE_CHECK", "UPGRADE")
