Oracle监听与tnsnames文件标准配置解决监听无法连接问题
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Helvetica}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Helvetica; min-height: 13.0px}
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
