Oracle 11g2的监听器配置

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:

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:

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

 

##静态服务注册添加条目
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:

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。
