ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

在配置oracle监听的时候竟然报了错：ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

以下是我报错的配置：

listener.ora的配置：

[oracle@sm2 admin]$ cat listener.ora 
LISTENER = (
        DESCRIPTION_LIST = (
                DESCRIPTION = 
                (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.137.82)(PORT = 1521))
                (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
)

SID_LIST_LISTENER = (
        SID_LIST = (
                SID_DESC =
                        (GLOBAL_DBNAME = sm2)
                        (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
                        (SID_NAME=sm2)
        )
)
ADR_BASE_LISTENER = /u01/app/oracle

tnsname.ora的配置：

[oracle@sm2 admin]$ cat tnsnames.ora 
sm2 = (
        DESCRIPTION = (
                ADDRESS_LIST = (
                        ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.137.82)(PORT = 1521)
                )
    )
    (ONNECT_DATA =
                (SERVICE_NAME = sm2)
                (SERVER = DEDICATED)
        )
)

监听能正常启动：

[oracle@sm2 admin]$ lsnrctl status

tnsping 能ping通：

[oracle@sm2 admin]$ tnsping sm2

使用sqlplus登陆时报错了：

[oracle@sm2 admin]$ sqlplus sys/oracle@sm2 as sysdba

ERROR:
ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

解决办法：

说明：其实上面出现这样的情况是在tnsname.ora中配置错了，将tnsname.ora中的ADDRESS_LIST参数去掉就行了。

最终的tnsname.ora中的配置变为：

[oracle@sm2 admin]$ cat tnsnames.ora

sm2 = (
	DESCRIPTION = (
		ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.137.82)(PORT = 1521)
	)
    (CONNECT_DATA =
		(SERVER = DEDICATED)
		(SERVICE_NAME = sm2)
	)
)

这样就行了

验证：

[oracle@sm2 admin]$ sqlplus sys/oracle@sm2 as sysdba
