Nueva creación de un entorno antiguo de EPM Cloud para auditorías

EPM Cloud soporta la compatibilidad con instantáneas solo para un ciclo mensual. Puede migrar instantáneas de mantenimiento del entorno de prueba al de producción y viceversa. Sin embargo, es posible que los requerimientos de auditoría de algunos clientes necesiten restaurar instantáneas de varios años en el entorno más reciente, y acceder a la aplicación en un periodo de tiempo breve.

Debe programar este script para que se ejecute una vez al mes a fin de convertir las instantáneas disponibles y hacerlas compatibles con el nivel de revisión más reciente de EPM Cloud. Oracle recomienda que ejecute un script después del tercer viernes del mes para asegurarse de que todos los problemas del entorno de producción se han resuelto.

Funcionamiento del script

Por cada instantánea que el cliente almacena, el script actualizado realiza estas tareas mediante el uso de EPM Automate:

1. Con la información del archivo input.properties, se conecta a un entorno.
2. Utiliza el comando recreate volver a crear el entorno.
3. Importa la instantánea en el entorno.
4. Ejecuta el mantenimiento diario en un entorno, lo que convierte la instantánea al formato compatible con el nivel de parche de EPM Cloud actual.
5. Descarga Artifact Snapshot (la instantánea de mantenimiento) en una carpeta. Si ha recreado un entorno 18.05 cargando instantáneas de snapshots/18.05, Artifact Snapshot se descarga en snapshots/18.06.
6. Envía por correo electrónico el resultado de la nueva creación de entornos antiguos a una dirección de correo electrónico si se especifica.

Ejecución del script

1. Cree el archivo input.properties y actualícelo con información de su entorno. Guarde el archivo en un directorio local. Este directorio lo denominaremos parentsnapshotdirectory. El contenido de este archivo difiere según su sistema operativo.

   Asegúrese de que tiene privilegios de escritura en este directorio. Para Windows, puede que necesite iniciar PowerShell mediante la opción Ejecutar como administrador para poder ejecutar los scripts.

2. Cree el script upgradeSnapshots.ps1 (Windows PowerShell) o upgradeSnapshots.sh (Linux/UNIX) y guárdelo en parentsnapshotdirectory, donde se ubica input.properties.
3. Cree un subdirectorio, por ejemplo, snapshots, en parentsnapshotdirectory.
4. En el directorio que ha creado en el paso anterior (snapshots), cree un subdirectorio para la instantánea mensual que desea convertir para hacerla compatible con el nivel de parche de EPM Cloud actual. Asigne un nombre al directorio con el formato YY.MM; por ejemplo, 18.05 para el directorio en el que se almacenan las instantáneas de mayo de 2018.
5. Copie las instantáneas en el subdirectorio adecuado. Por ejemplo, copie las instantáneas de mayo de 2018 en snapshots/18.05.
6. Inicie el script.
   • Linux/UNIX: ejecute ./upgradeSnapshots.sh.
   • Windows PowerShell: ejecute upgradeSnapshots.ps1.

Windows

Cree los scripts input.properties y upgradeSnapshots.ps1 copiando los scripts de esta sección.

Creación de input.properties

username=exampleAdmin
userpassword=examplePassword
serviceurl=exapleURL
proxyserverusername=proxyServerUserName
proxyserverpassword=proxyPassword
proxyserverdomain=proxyDoamin
parentsnapshotdirectory=C:/some_directory/snapshots
emailtoaddress=exampleAdmin@oracle.com

Actualización de input.properties

Creación de upgradeSnapshots.ps1
