-- 我的测试环境：primary的tnsnames别名test，standby主机的tnsnames别名testdg。数据库版本：11GR2.
-- 基本学习完成,再补充一些不常用命令:

DGMGRL> help

The following commands are available:

add            Adds a standby database to the broker configuration
connect        Connects to an Oracle database instance
convert        Converts a database from one type to another
create         Creates a broker configuration
disable        Disables a configuration, a database, or fast-start failover
edit           Edits a configuration, database, or instance
enable         Enables a configuration, a database, or fast-start failover
exit           Exits the program
failover       Changes a standby database to be the primary database
help           Displays description and syntax for a command
quit           Exits the program
reinstate      Changes a database marked for reinstatement into a viable standby
rem            Comment to be ignored by DGMGRL
remove         Removes a configuration, database, or instance
show           Displays information about a configuration, database, or instance
shutdown       Shuts down a currently running Oracle database instance
sql            Executes a SQL statement
start          Starts the fast-start failover observer
startup        Starts an Oracle database instance
stop           Stops the fast-start failover observer
switchover     Switches roles between a primary and standby database

Use "help " to see syntax for individual commands

-- 还可以在dgmgrl执行startup以及shutdown数据库.使用一些sql可以执行一些管理命令.
DGMGRL> connect sys/btbtms@test
Connected.
DGMGRL> sql 'alter system checkpoint ';
Succeeded.
