当执行下列命令时出现ORA-12514错误
[oracle@edbjr2p1 admin]$ sqlplus system/oracle@PROD
SQL*Plus: Release 11.2.0.4.0 Production on Sat May 3 12:25:27 2014

ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
解决：
1.查看listener.ora文件
[oracle@edbjr2p1 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = edbjr2p1.us.oracle.com)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
)

ADR_BASE_LISTENER = /u01/app/oracle
2.查看tnsnames.ora文件
[oracle@edbjr2p1 admin]$ cat tnsnames.ora
PROD =
(DESCRIPTION =
                (ADDRESS =
                        (PROTOCOL = TCP)
                        (HOST = edbjr2p1.us.oracle.com)
                        (PORT = 1521)
                )
                (CONNECT_DATA =
                        (SERVICE_NAME = PROD.us.oracle.com)
                )
        )
3.在listener.ora中增加下列几行
[oracle@edbjr2p1 admin]$ vim listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = edbjr2p1.us.oracle.com)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
)
SID_LIST_LISTENER =
        (SID_LIST =
                (SID_DESC =
                (GLOBAL_DBNAME = PROD.us.oracle.com)
                (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
                (SID_NAME = PROD)
                )
        )
ADR_BASE_LISTENER = /u01/app/oracle
4.测试是否成功
