為稽核重新建立舊的 Cloud EPM 環境

Cloud EPM 僅支援一個月週期的快照相容性；您可以將維護快照從測試環境移轉至生產環境，反之亦然。但是，某些客戶的稽核要求可能需要在最近的環境中還原多年的快照，並在短時間內存取應用程式。

您應該將此指令碼排定為每個月執行一次，以轉換可用的快照並使其與最新的 Cloud EPM 修補程式層級相容。Oracle 建議您在每個月的第三個星期五之後執行該指令碼，以確保生產環境中的所有問題皆已解決。

指令碼的運作方式

對於客戶儲存的每個快照，使用 EPM Automate 升級指令碼完成下列任務：

1. 使用 input.properties 檔案中的資訊，登入環境
2. 使用 recreate 命令以翻新環境
3. 將快照匯入環境
4. 對環境進行日常維護，這會造成將快照轉換為與目前 Cloud EPM 修補程式層級相容的格式。
5. 將 Artifact Snapshot (維護快照) 下載到資料夾。如果藉由從 snapshots/18.05 上傳快照來重新建立 18.05 環境，則 Artifact Snapshot 會下載至 snapshots/18.06。
6. 將重新建立舊環境的結果透過電子郵件傳送到某個電子郵件地址 (若有指定)。

執行指令碼

1. 建立 input.properties 檔案，並使用環境資訊對其進行更新。將檔案儲存在本機目錄中。這個目錄在此探討中稱為 parentsnapshotdirectory。此檔案的內容因作業系統而異。

   確保您在此目錄中具有寫入權限。至於 Windows，您可能需要使用以管理員身分執行選項來啟動 PowerShell，才能執行指令碼。

2. 建立 upgradeSnapshots.ps1 (Windows PowerShell) 或 upgradeSnapshots.sh (Linux/UNIX) 指令碼，並將其儲存在 input.properties 所在的 parentsnapshotdirectory 中。
3. 建立子目錄，例如 snapshots，位於 parentsnapshotdirectory 中。
4. 在您在上一步驟建立的目錄 (snapshots) 中，為要轉換的每月快照建立一個子目錄，使其與目前的 Cloud EPM 修補程式層級相容。使用 YY.MM 格式來命名目錄；例如，18.05 的目錄可儲存 2018 年 5 月的快照。
5. 將快照複製到適當的子目錄。例如，將 2018 年 5 月的快照複製到 snapshots/18.05。
6. 啟動指令碼。
   • Linux/UNIX：執行 ./upgradeSnapshots.sh。
   • Windows PowerShell：執行 upgradeSnapshots.ps1。

Windows

複製本節中的指令碼，以建立 input.properties 和 upgradeSnapshots.ps1 指令碼。

建立 input.properties

proxyserverpassword=proxyPassword
proxyserverdomain=proxyDoamin
