配置data guard网络监听的时候，连接测试报错如下：
error:
ora-12514: tns:listener does not currently know of service requested in connect
descriptor
出错原因是由于，在修改init$oracle_sid.ora文件时，在主库里面新添加了一项db_unique_name=10gpri；
备库上新添加一项db_unique_name=10gstandby.
在配置监听文件和客户端tnsnames.ora时，就要修改global_dbname 成相应的10gpri或10standby.
[oracle@dg01 admin]$ cat listener.ora
listener =
(description_list =
(description =
(address_list =
(address = (protocol = tcp)(host = 172.21.1.30)(port = 1521))
)
)
)
sid_list_listener =
(sid_list =
(sid_desc =
(sid_name = plsextproc)
(oracle_home = /u01/oracle/product/10.2.0/db_1 )
(program = extproc)
)
(sid_desc =
(global_dbname = 10gpri)
(oracle_home = /u01/oracle/product/10.2.0/db_1)
(sid_name = dg01)
)
)
[oracle@dg01 admin]$ cat tnsnames.ora
10gpri=
(description =
(address = (protocol = tcp)(host = 172.21.1.30)(port = 1521))
(connect_data =
(server=dedicated)
(service_name = 10gpri)
)
)
10gstandby=
(description =
(address = (protocol = tcp)(host = 172.21.1.31)(port = 1521))
(connect_data =
(server=dedicated)
(service_name = 10gstandby)
)
)
在两个节点上测试如下：
