使用脚本在 Linux、UNIX 或 Windows 上的 DB2 中创建地理数据库

您可以复制并修改示例脚本以便在 Linux、UNIX 或 Windows 上的现有 IBM DB2 数据库中创建地理数据库。

在运行脚本之前必须完成一些附加任务。以下步骤对这些任务和脚本自身进行了介绍:

步骤:
  1. 在服务器上安装并配置 DB2
  2. 在 DB2 服务器上创建名为 sde 的操作系统登录。
  3. 将 sde 用户添加到具有 SYSMON 权限的组。
  4. 创建一个数据库并注册到 Spatial Extender。
  5. 将数据库上的 DBADM 授予 sde 用户。
  6. 如果要从 DB2 服务器以外的计算机运行 Python 脚本,请在将要运行脚本的计算机上安装并配置 DB2 客户端。

    DB2 客户端安装程序可从 Esri 客户关怀中心门户网站下载。如果安装 DB2 客户端运行 32 位 ArcGIS 客户端,则安装 32 位版本的 DB2 客户端。如果安装 DB2 客户端运行 ArcGIS 服务器,则安装 64 位版本的 DB2 客户端。有关详细信息,请参阅设置到 DB2 的连接

  7. 将示例脚本复制到已安装 ArcGIS Desktop(ArcEditor 或 ArcInfo)、ArcGIS Server(标准版或高级版)、或 ArcGIS Engine 及 Geodatabase Update 扩展模块的 ArcGIS Desktop 或任意 Python IDE(例如 PythonWin 或 WING)的 Python 窗口中。

    此示例脚本在现有 DB2 数据库中启动地理数据库功能:

  8. 修改此脚本以包含特定于您的站点的信息。
  9. 运行您复制和更改的脚本。

用于地理数据库创建的日志文件 (GDBCreateGeodatabase<#>.log) 会写入运行此脚本的计算机上 TEMP 或 TMP 变量所指定的目录。
