oracle一個別例項配置多個listener或多個埠

Oracle
listener.ora檔案的內容如下:
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))
)
)
上面的配置只配置了一個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名稱一致。
SID_DESC則註冊要提供服務的資料庫例項名。這樣LISTENER2 才能夠提供服務。
再來啟動兩個listener
[oracle@jingyong udump]$ lsnrctl stop listener

一個oracle例項對於多個監聽，一個監聽對於多個埠。
現在我們可以建立一個oracle例項一個監聽的兩個埠。這一共有兩種方法：
在listener檔案新增一行，具體如下：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = jingyong)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = jingyong)(PORT = 1522))
)
)
這時我們只有重啟監聽，就可以用兩個埠連線資料庫例項了。。。。
當然我們也可以一個例項啟動兩個監聽，但是具體只有一個監聽起作用。
我們可以在一個資料庫下，一個例項對於一個監聽，但例項必須在不同目錄。或者先建監聽，再建例項。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))
)
)
