Networker恢復oracle rac到單機

此處oracle為oracle19c pdb

參考 Networker恢復oracle單節點，這裡主要列出來一些不同之處

oracle恢復過程

此處oracle204是我用來恢復的單機

在oracle204機器上，建立最簡單的c引數檔案

restore database

因為我spfile裡面已經設定了，如果沒有設定，需要在rman恢復指令碼里自己指定檔案轉換

db_file_name_convert  和  db_file_name_convert引數會自動轉換asm路徑檔案到本地路徑

所以直接restore database
