Oracle監聽與tnsnames檔案標準配置解決監聽無法串連問題

Oracle監聽與tnsnames檔案標準配置解決監聽無法串連問題

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}

解決一則問題如下：

1.建立立監聽程式報錯：連接埠被佔用

2.ORA-12514:監聽程式當前無法識別串連描述符中請求的服務

解決如下：

1.在Oracle 11g network/admin目錄下建立lintener.ora監聽檔案，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目錄下建立tnsnames.ora檔案，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.重啟監聽程式。

lsnrct reload

4.查看監聽程式

[oracle@reportdb ~]$ lsnrctl status
