Oracle 12c 新特性 --- Oracle Data Guard Broker 支持执行DGMGRL命令脚本
作者：

概念
This feature enables command scripts to be executed through the Oracle Data Guard broker DGMGRL command-line interface; much like in SQL*Plus. DGMGRL commands, SQL commands using the broker SQL command, and operating system commands using the new HOST (or !) capability can be put into a file and executed on the DGMGRL command line.
该特性使命令脚本可以通过Oracle Data Guard broker DGMGRL命令行界面执行;就像在SQL*Plus。DGMGRL命令、使用代理SQL命令的SQL命令，以及使用新的主机(或!)功能的操作系统命令可以放入文件中，并在DGMGRL命令行上执行。
This feature enables customers who use the standard interface to Oracle Data Guard (DGMGRL) in their broker configurations to use scripts for Oracle Data Guard operations.
该特性使使用标准接口的客户可以在其代理配置中使用Oracle Data Guard(DGMGRL)，从而为Oracle数据保护操作使用脚本。
实验
1）@命令允许执行存储在脚本文件中的DGMGRL命令，脚步里的命令是能在DGMGRL命令行执行的脚步： 详细更多可执行命令可参考官方文档：
