Создание базы геоданных с помощью скриптов в Oracle

Для создания базы геоданных в системе управления базами данных Oracle, вы можете скопировать и отредактировать один из предоставленных примеров скриптов.

Перед запуском скрипта необходимо выполнить дополнительные действия. Описание этих действий и самого скрипта приводится ниже.

Шаги:

1. Установите и настройте Oracle на своем сервере.
2. Если вы будете запускать скрипт Python с другого компьютера, а не с сервера Oracle, установите клиент Oracle на компьютер, с которого будет запускаться скрипт Python.

   Клиент Oracle можно загрузить с портала поддержки пользователей Esri (Esri Customer Care Portal). Если вы будете запускать скрипт из 32-битного клиента ArcGIS, загрузите 32-битную версию клиента Oracle. Если вы будете запускать скрипт из ArcGIS for Server, загрузите 64-битную версию клиента Oracle. Дополнительные сведения см. в разделе Настройка подключения к Oracle.

3. Скопируйте один из этих примеров скриптов в окно Python в ArcGIS for Desktop или в любой Python IDE, например, PythonWin или WING, на компьютере с установленным ArcGIS for Desktop (Standard или Advanced), ArcGIS for Server (Standard или Advanced) или ArcGIS Engine с дополнительным модулем Geodatabase Update.

   Данный пример создает пользователя sde и табличное пространство, задает пользовательские права доступа для создания базы геоданных, и затем создает базу геоданных:

4. Измените скрипт, чтобы включить информацию, относящуюся к вашему сайту.
5. Запустите скопированный и измененный скрипт.

Файл отчета о создании базы геоданных (GDBCreateGeodatabase<#>.log) будет записан в папку, заданную переменной TEMP или TMP на компьютере, где был запущен скрипт.
