oracle11g rac监听配置的示例分析

这篇文章主要介绍了oracle11g rac监听配置的示例分析，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

（1）概述
rac配置如下：
[grid@dbrac1 admin]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.56.2    dbrac1
192.168.56.3    dbrac1-vip
10.10.10.10     dbrac1-priv

192.168.56.4    dbrac2
192.168.56.5    dbrac2-vip
10.10.10.11     dbrac2-priv

192.168.56.8 rac-scan
[grid@dbrac1 admin]$

一、查看节点1的oracle、grid用户下的监听及tns配置文件
oracle用户下：
[oracle@dbrac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

DBRAC =

    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dbrac)
    )
)

[oracle@dbrac1 admin]$
[oracle@dbrac1 admin]$ sqlplus / as sysdba

[grid@dbrac1 admin]$ lsnrctl status LISTENER_SCAN1

LSNRCTL for Linux: Version 11.2.0.4.0 – Production on 19-OCT-2017 14:43:09

local_listener 默认不需要配置，默认配置指向1521端口，对于单实例改变端口需要指向tns里的连接字符串，而在rac配置中默认指向本节点的vip。
remote_listener指向的是scan监听名，需要远程监听是配置。

Oracle 11.2版本后，有一个新的监听文件endpoints_listener.ora被引进，里面的内容是节点的IP和VIP信息。
Endpoints_listener.ora 文件的作用是向后兼容11.2版本以前的数据库，DBCA建库时，需要通过获取endpoints的位置信息来配置数据库参数和tnsnames，其中最下面两行参数涉及ENABLE_GLOBAL_DYNAMIC_ENDPOINT参数，ENABLE_GLOBAL_DYNAMIC_ENDPOINT参数的作用是允许监听程序接受针对oracle 11.2版本之前未进行动态注册的连接

（2）使用srvctl 工具添加监听并手动加入静态注册信息
–添加监听：（在grid用户下执行）
[grid@dbrac2 admin]$ srvctl config network
Network exists: 1/192.168.56.0/255.255.255.0/eth0, type static
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl add listener -h

Adds a listener configuration to the Oracle Clusterware.

Usage: srvctl add listener [-l ] [-s] [-p "[TCP:][, …][/IPC:][/NMP:][/TCPS:] [/SDP:]"] [-o ] [-k ]
    -l            Listener name (default name is LISTENER)
    -o          ORACLE_HOME path (default value is CRS_HOME)
    -k              network number (default number is 1)
    -s                       Skip the checking of ports
    -p "[TCP:][, …][/IPC:][/NMP:][/TCPS:] [/SDP:]"       Comma separated tcp ports or listener endpoints
    -h                       Print usage

-k 填入方才获得的network number，-p填入端口号，-l填入监听名，-o 填入GI HOME路径

–执行：
[grid@dbrac2 admin]$ srvctl add listener -l LISTENER_wang -o $ORACLE_HOME -p 1522 -k 1
[grid@dbrac2 admin]$

–查询监听状态：
[grid@dbrac2 admin]$ srvctl status listener -h

Displays the current state of the listener.

Usage: srvctl status listener [-l ] [-n ] [-v]
    -l            Listener name
    -n            Node name
    -v                       Verbose output
    -h                       Print usage
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_wang
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is not running
[grid@dbrac2 admin]$

–启动监听：
[grid@dbrac2 admin]$ srvctl start listener -l LISTENER_wang
[grid@dbrac2 admin]$

–查看新建的监听状态：
[grid@dbrac2 admin]$ lsnrctl stauts LISTENER_wang

LISTENER_WANG_DBRAC2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=dbrac2-vip)(PORT=1522))(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.56.4)(PORT=1522)(IP=FIRST))))# line added by Agent

–之后仅需要加入静态注册信息即可,如:
SID_LIST_LISTENER_WANG =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = dbrac)
      (ORACLE_HOME = /oracle/app/11.2.0/grid)
      (SID_NAME=dbrac2)
    )
)

加入如上信息到listener.ora配置文件中(SID_LIST_($LISTENER_NAME)，并重启监听即完成静态注册：
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_WANG
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is running on node(s): dbrac1,dbrac2
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl stop listener -l LISTENER_WANG
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_WANG
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is not running
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl start listener -l LISTENER_WANG -n dbrac2
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_WANG
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is running on node(s): dbrac2
命令srvctl start listener -l LISTENER_WANG -n dbrac2只在一个节点启动监听

–启动监听不加参数默认是在两个节点同时启动
[grid@dbrac2 admin]$ srvctl stop listener -l LISTENER_WANG
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_WANG
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is not running
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl start listener -l LISTENER_WANG -n dbrac1,dbrac2
PRKO-2003 : Invalid command line option value: dbrac1,dbrac2
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl start listener -l LISTENER_WANG
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_WANG
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is running on node(s): dbrac1,dbrac2

–查询监听LISTENER_WANG状态：
[grid@dbrac2 admin]$ lsnrctl status LISTENER_WANG
