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;
}
