解决一则问题如下:

1.新建立监听程序报错:端口被占用

2.ORA-12514:监听程序当前无法识别连接描述符中请求的服务


解决如下:

1.在Oracle 11g  network/admin目录下建立lintener.ora监听文件,配置如下:

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.


SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

(PROGRAM = extproc)


)    

(SID_DESC =

(SID_NAME = orcl)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

)

)


LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = reportdb)(PORT = 1522))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))

)

)


ADR_BASE_LISTENER = /u01/app/oracle



2.在 network/admin目录下建立tnsnames.ora文件,配置如下:

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.



LISTENER_ORCL =

(ADDRESS = (PROTOCOL = TCP)(HOST = reportdb)(PORT = 1522))


ORACLR_CONNECTION_DATA =  

(DESCRIPTION =  

(ADDRESS_LIST =  

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))  

)  

(CONNECT_DATA =  

(SID = CLRExtProc)  

(PRESENTATION = RO)  

)  

)  


ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = reportdb)(PORT = 1522))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)


3.重启监听程序。

lsnrct reload


4.查看监听程序

[oracle@reportdb ~]$ lsnrctl status

命令执行成功


5.Tnsping ORCL实例测试

[oracle@reportdb ~]$ tnsping orcl

已使用的参数文件:


已使用 TNSNAMES 适配器来解析别名

尝试连接 (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = reportdb)(PORT = 1522)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl)))

OK (0 毫秒)
