Secuenciar los comandos de la base de datos y la creación de la geodatabase en PostgreSQL

Puede copiar y modificar una de las secuencias de comandos de ejemplo provistas. Uno crea una base de datos y una geodatabase en un cluster de base de datos de PostgreSQL. El otro crea una geodatabase en una base de datos PostgreSQL existente configurada previamente.

Existen tareas adicionales que debe completar antes de ejecutar la secuencia de comandos. Aquellas tareas y secuencias de comandos en si se describen en los siguientes pasos:

Pasos:

1. Instale y configure PostgreSQL en el servidor.
2. Modifique el archivo pg_hba.conf para permitir la conexión con el cluster de la base de datos.
3. Cree un directorio y el espacio de tabla para almacenar la base de datos de PostgreSQL.
4. Si desea ejecutar la secuencia de comandos de Python desde un equipo diferente al servidor en donde se instaló PostgreSQL, instale el cliente libpq de PostgreSQL en el equipo desde el que ejecutará la secuencia de comandos de Python.

   Los archivos cliente de PostgreSQL se pueden descargar desde el Portal de atención al cliente de Esri. Estará ejecutando la secuencia de comandos desde un cliente de 32 bits de ArcGIS, descargue los archivos del cliente de PostgreSQL de 32 bits. Si desea ejecutar la secuencia de comandos de ArcGIS for Server, descargue los archivos de cliente de PostgreSQL de 64 bits. Consulte en Configurar una conexión con PostgreSQL para obtener más información.

5. Copie una de estas secuencias de comandos de ejemplo en la ventana de Python en ArcGIS for Desktop o a cualquier IDE de Python, como PythonWin o WING, en un equipo donde ArcGIS for Desktop (Standard o Advanced), ArcGIS for Server Enterprise (Standard o Advanced) o ArcGIS Engine con la extensión Geodatabase Update está instalado.

   En este ejemplo crea un esquema y usuario de sde, se otorgan los privilegios de usuario sde para crear una geodatabase, se especifica un espacio de tabla para almacenar la base de datos, crea una base de datos y, a continuación, crea la geodatabase.

6. Altere la secuencia de comando para incluir la información específica a su sitio.
7. Ejecute la secuencia de comandos que copió y que modificó.

Un archivo de registro para la creación de geodatabase (GDBCreateGeodatabase<#>.log) se escribe en el directorio especificado para la variable TEMP o TMP en el equipo en el que se ejecuta la secuencia de comandos.
