oracle数据库中有2个实例，监听怎么配置

环境 centos 5.4 + oracle 10g r2

已有实例 xxxio 和监听listener 端口1521

现又新建实例 xxxdb 监听名称listener02 端口 1522实现 listener02 只加载实例 xxxdb

1.创建数据库 实例名xxxdb

2.netca 创建监听 listener02 端口1522

3.配置listener.ora 如下

# listener.ora Network Configuration File: /u01/app/oracle/product/10g//network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = xxxio)

(ORACLE_HOME = /u01/app/oracle/product/10g/)(PROGRAM = extproc)

)

(SID_DESC =

(SID_NAME = +ASM)

(ORACLE_HOME = /u01/app/oracle/product/10g/))

(SID_DESC =

(SID_NAME = xxxdb)

(ORACLE_HOME = /u01/app/oracle/product/10g/))

)

SID_LIST_LISTENER02 =

(SID_LIST =

(SID_DESC =

(SID_NAME = xxxdb)

(ORACLE_HOME = /u01/app/oracle/product/10g/))

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))

)

LISTENER02 =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1522)))

)

说明 ： 自己在配置过程中也遇到了好多问题 ，最后通过查看资料和实际测试 证明上述的配置是正确的1.首先用netca创建 listener02 后 会在配置文件listener.ora中 生成如下的信息 。这说明一个监听创建成功。

可以启动 、关闭 。但是没有加载实例。

LISTENER02 =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1522)))

)

2.在配置文件listener.ora 中加入如下信息 ，才能将实例xxxdb 加载到监听 listener02中 实现 各尽其职SID_LIST_LISTENER02 = --这的命名是SID_LIST_监听名(SID_LIST =

(SID_DESC =

(SID_NAME = xxxdb)

(ORACLE_HOME = /u01/app/oracle/product/10g/))

)

你好的！

正常来说如果跨实例的话，需要建立dblink!

完后直接insert into 表1 select * from 表2@dblinkName；

不知道还有什么问题！

欢迎采纳！
