ORA-12514: TNS:listener does not currently know of service requested in connect

1，登录报错如下：

[oracle@oracle_yueworld admin]$ rlwrap sqlplus system/system51@st1SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 3 16:33:26 2015Copyright (c) 1982, 2009, Oracle.  All rights reserved.ERROR:ORA-12514: TNS:listener does not currently know of service requested in connectdescriptor

2，查看下lsnrctl状态，看是否是lsnrctl监听的问题

[oracle@oracle_yueworld admin]$ lsnrctl statusLSNRCTL for Linux: Version 11.2.0.1.0 - Production on 03-DEC-2015 17:03:07Copyright (c) 1991, 2009, Oracle.  All rights reserved.Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.121.51)(PORT=1521)))STATUS of the LISTENER------------------------Alias                     LISTENERVersion                   TNSLSNR for Linux: Version 11.2.0.1.0 - ProductionStart Date                03-DEC-2015 17:02:55Uptime                    0 days 0 hr. 0 min. 11 secTrace Level               offSecurity                  ON: Local OS AuthenticationSNMP                      OFFListener Parameter File   /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.oraListener Log File         /oracle/app/oracle/diag/tnslsnr/oracle_yueworld/listener/alert/log.xmlListening Endpoints Summary...  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.121.51)(PORT=1521)))The listener supports no servicesThe command completed successfully[oracle@oracle_yueworld admin]$ [oracle@oracle_yueworld admin]$ 

从中可以看出监听正常，但是The listener supports no services这个貌似是不识别service_name啊

3，去查看下参数

SQL> show parameter name;NAME                     TYPE    VALUE------------------------------------ ----------- ------------------------------db_file_name_convert             string  /oracle/app/oracle/oradata/pow                         erdes, /oracle/app/oracle/orad                         ata/orcldb_name                  string  orcldb_unique_name               string  stunqglobal_names                 boolean     FALSEinstance_name                string  orcllock_name_space              stringlog_file_name_convert            stringservice_names                string  stunqSQL> 

看到db_name和db_unique_name以及service_names不一样

4，解决方案

在listener.ora文件里面添加SID_LIST_LISTENER，如下所示：

[oracle@oracle_yueworld admin]$ more listener.ora # listener.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER =  (SID_LIST =    (SID_DESC =      (GLOBAL_DBNAME = stunq)      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/dbhome_1)      (SID_NAME = stunq)    )  )LISTENER =  (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.51)(PORT = 1521))  )ADR_BASE_LISTENER = /oracle/app/oracle[oracle@oracle_yueworld admin]$ 

再重启lsnrctl服务:

[oracle@oracle_yueworld admin]$ lsnrctl startLSNRCTL for Linux: Version 11.2.0.1.0 - Production on 03-DEC-2015 18:00:09Copyright (c) 1991, 2009, Oracle.

Instance "stunq", status UNKNOWN, has 1 handler(s) for this service...The command completed successfully[oracle@oracle_yueworld admin]$ 

看到The listener supports no services错误已经没有了，可以去试试登录

5，再次登录报错

[oracle@oracle_yueworld admin]$ rlwrap sqlplus  orclk/st141118@st1SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 3 18:03:55 2015Copyright (c) 1982, 2009, Oracle.

6，去修改服务端和客户端的配置文件

google了很多资料，大部分都说是listener.ora配置错误导致listener找不到你要请求的sid。这有两种可能，一种是client端的tnsnames.ora中配置了错误的SID，一种是server端的listener.ora中配置错了SID。仔细检查，然后开始修改服务器listener.ora listener.ora，将SID_NAME修改成正确的instance_name为orcl

[oracle@oracle_yueworld admin]$ more listener.ora # listener.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER =  (SID_LIST =    (SID_DESC =      (GLOBAL_DBNAME = stunq)      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/dbhome_1)      (SID_NAME = orcl)    )  )  #PS: 这里面的SID_NAME是oracle实例名，GLOBAL_DBNAME是全局的dbname，是db_unique_nameLISTENER =  (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.51)(PORT = 1521))  )ADR_BASE_LISTENER = /oracle/app/oracle[oracle@oracle_yueworld admin]$ 

修改客户端tnsnames.ora

[oracle@oracle_yueworld admin]$ vim tnsnames.ora # tnsnames.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora# Generated by Oracle configuration tools.st1 =  (DESCRIPTION =    (ADDRESS_LIST =      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.51)(PORT = 1521))    )    (CONNECT_DATA =      (SERVICE_NAME = stunq)    )  )  # PS：这里的service_name就是可以从执行 show parameter name;中显示的service_names参数值。

7，然后验证登录，成功了，如下所示：

[oracle@oracle_yueworld admin]$ [oracle@oracle_yueworld admin]$  rlwrap sqlplus orclk/st141118@st1SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 3 19:43:10 2015Copyright (c) 1982, 2009, Oracle.  All rights reserved.Connected to:Oracle Database 11g Release 11.2.0.1.0 - 64bit ProductionSQL>
