Oracle 11g2的监听器配置教程

2017年12月12日  | 移动技术网IT编程  | 我要评论
oracle的监听器服务注册方式有两种，分别为动态和静态。通过动态注册的服务在lsnrctl status时显示的状态为ready，静态的服务为unknown。
11g2以前的版本，监听器通过listener.ora文件进行配置。在11g2版本中，监听器的配置方式发生了变化，增加了一个新的配置文件endpoints_listener.ora，并且此文件和原来的listener.ora文件都转移到$grid_home/network/admin目录下了。

11g2的监听器的配置信息保存在$grid_home/network/admin/listener.ora和endpoints_listener.ora两个文件中。
文件endpoints_listener.ora的内容如下：
.ora代码
复制代码 代码如下:

listener_serv2=
(description=
(
address_list=
(address=(protocol=tcp)(host=xxdb2-vip)(port=1551))
(address=(protocol=tcp)(host=10.10.10.100)(port=1551)(ip=first))
)
)

文件listener.ora的内容如下：
.ora代码
复制代码 代码如下:

listener=(description=(address_list=(address=(protocol=ipc)(key=listener)))) # line added by agent
listener_scan1=(description=(address_list=(address=(protocol=ipc)(key=listener_scan1)))) # line added by agent
enable_global_dynamic_endpoint_listener_scan1=on # line added by agent
enable_global_dynamic_endpoint_listener=on # line added by agent
enable_global_dynamic_endpoint_listener_wfg=on # line added by agent

.ora代码
##静态服务注册添加条目
复制代码 代码如下:

sid_list_listener =
(sid_list =
(sid_desc =
(global_dbname = servdb)
(oracle_home = /u01/oracle/app/oracle/product/10.2.0/db)
(sid_name = servdb1)
)
)

如果需要添加静态注册的服务，和以前版本一样是在listener.ora文件中添加相应的条目。
使用lsnrctl status listener检查监听器状态，如下：
log代码
复制代码 代码如下:

在11g2的grid infrastructure上安装oracle 10g，10g的监听器配置文件也要采用$grid_home/network/admin下的文件。
但需要做一个折中操作，将10g的$oracle_home/network/admin下listener.ora文件设置为$grid_home/network/admin下endpoints_listener.ora的文件链接。
