执行RMAN 存储脚本

• 执行脚本：

RUN { EXECUTE SCRIPT

script_name

; }

• 执行全局脚本：

RUN { EXECUTEGLOBAL SCRIPT

script_name

; }

连接到目标数据库和恢复目录，然后使用EXECUTE SCRIPT命令即可执行存储脚本。请注意，EXECUTE SCRIPT命令需要RUN块。如果脚本中的某一RMAN 命令失败，则不会执行脚本中的后续RMAN 命令。

执行脚本时，脚本将使用当时配置的自动通道。如果需要替换已配置的通道，请在脚本中使用ALLOCATE CHANNEL命令，如下例所示：

RMAN> RUN

{

ALLOCATE CHANNEL ch1 DEVICE TYPE DISK;

ALLOCATE CHANNEL ch2 DEVICE TYPE DISK;

ALLOCATE CHANNEL ch3 DEVICE TYPE DISK;

EXECUTE SCRIPT full_backup;

}
