Oracle一个实例配置多个listener或多个端口

一个oracle实例对于多个监听，一个监听对于多个端口。现在我们可以创建一个oracle实例一个监听的两个端口。这一共有两种方法：

Oracle一个实例配置多个listener或多个端口

listener.ora文件的内容如下:

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))

)

)

上面的配置只配置了一个listener

下面再增加一个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_ 这里的要和LISTENER名称一致。

SID_DESC则注册要提供服务的数据库实例名。这样LISTENER2 才能够提供服务。

再来启动两个listener

[oracle@jingyong udump]$ lsnrctl stop listener
