ArcGIS Help 10.1 - 在 Oracle 中编写企业级地理数据库升级脚本

可以修改和使用在本主题中提供的其中一个 Python 脚本来连接和升级企业级地理数据库。

第一个脚本使用现有数据库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。此脚本在您无法访问 ArcGIS for Desktop 时特别有用；您可以在安装了具有 Geodatabase Update 扩展模块的 ArcGIS Engine Runtime 或 ArcGIS for Server Enterprise（Standard 或 Advanced）的计算机上运行 Python 脚本、提供连接信息和升级地理数据库。

无论是使用现有数据库连接文件还是通过脚本中的参数，您所建立的与地理数据库之间的连接都是直连。运行脚本的计算机上必须有以下内容：

Oracle 客户端，配置为连接到数据库
如果将从 32 位 ArcGIS 客户端升级，则必须使用 32 位 Oracle 客户端。
ArcGIS 客户端，可能是 ArcGIS for Desktop（高级版或标准版）、具有 Geodatabase Update 扩展模块的 ArcGIS Engine Runtime 或 ArcGIS for Server Enterprise（Standard 或 Advanced）
确保在运行脚本前对 ArcGIS 客户端授权。

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

步骤:

将这些脚本之一复制到 ArcGIS for 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。

如果现有数据库连接文件使用直连并以 ArcSDE 管理员的身份进行连接，则根据不同的操作系统来修改和使用以下脚本之一：

# Name: upgradesdegdb_Example.py
# Description: Connect from a Windows computer 
# with an existing database connection file 
# and upgrade an enterprise geodatabase in Oracle
# 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(Default_gdb, "PREREQUISITE_CHECK", "UPGRADE")

# Name: upgradesdegdb_Example.py
# Description: Connect from a Linux or UNIX computer 
# with an existing database connection file 
# and upgrade an enterprise geodatabase in Oracle
# Author: Esri

# Import arcpy module
import arcpy
 
# Local variables:
Output_Workspace = "<user>/connections/<Connection_file>"
Default_gdb = "<user>/connections/<Connection_file>"

# Process: Upgrade Geodatabase
arcpy.UpgradeGDB_management(Default_gdb, "PREREQUISITE_CHECK", "UPGRADE")

如果计算机上没有用于编写升级脚本的数据库连接文件，则可复制和修改以下脚本：

Type upgrade_gdb.py -h or upgrade_gdb.py --help for usage
