oracle 多執行個體 端口,oracle一個别執行個體配置多個listener或多個端口

listener.ora檔案的内容如下:

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = jingyong)

(ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)

(SID_NAME = jingyong)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = jingyong)(PORT = 1521))

)

)

上面的配置隻配置了一個listener

下面再增加一個listener_2

SID_LIST_LISTENER_2 =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = jingyong)

(ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)

(SID_NAME = jingyong)

)

)

LISTENER_2 =

(DESCRIPTION_LIST =

(DESCRIPTION =

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

)

)

SID_LIST_這裡的要和LISTENER名稱一緻。

SID_DESC則注冊要提供服務的資料庫執行個體名。這樣LISTENER2 才能夠提供服務。

再來啟動兩個listener

一個oracle執行個體對于多個監聽，一個監聽對于多個端口。

現在我們可以建立一個oracle執行個體一個監聽的兩個端口。這一共有兩種方法：

在listener檔案添加一行，具體如下：

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = jingyong)(PORT = 1521))

)

(DESCRIPTION =

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

)

)

這時我們隻有重新開機監聽，就可以用兩個端口連接配接資料庫執行個體了。。。。

當然我們也可以一個執行個體啟動兩個監聽，但是具體隻有一個監聽起作用。

我們可以在一個資料庫下，一個執行個體對于一個監聽，但執行個體必須在不同目錄。或者先建監聽，再建執行個體。一樣能達到效果。。。

具體配置如下：

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = jingyong)

(ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)

(SID_NAME = jingyong)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = jingyong)(PORT = 1521))

)

)

SID_LIST_LISTENER_2 =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = jingyong)

(ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)

(SID_NAME = jingyong)

)

)

LISTENER_2 =

(DESCRIPTION_LIST =

(DESCRIPTION =

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

)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = jingyong)(PORT = 1523))

)
