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：<span style="color:#ff0000;">ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA</span>

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
