一、在配置好的DG上修改Listener文件，增加GLOBAL_DBNAME.
注意這裏的GLOBAL_DBNAME參數格式：<db_unique_name>_DGMGRL.<db_domain> 的連接。
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.150)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcm)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcm)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl_st_DGMGRL)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcm)
)
)
ADR_BASE_LISTENER = /u01/app/oracle二、重啓監聽，會發信啊之前配置的orcl_st_DGMGRL也註冊進來了

4.啓用fast_start如果報警告，是因爲需要先在別的機器啓動start observer。start observer需要單獨在服務器上啓動，在後臺自動運行，不能關閉，否則主備庫就無法自動監控運行狀態。就無法使用快速啓動故障轉移功能。
