這篇文章主要介紹了 oracle11g rac 監聽配置的示例分析，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓丸趣 TV 小編帶著大家一起了解一下。
（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]$

local_listener 默認不需要配置，默認配置指向 1521 端口，對于單實例改變端口需要指向 tns 里的連接字符串，而在 rac 配置中默認指向本節點的 vip。
remote_listener 指向的是 scan 監聽名，需要遠程監聽是配置。
Oracle 11.2 版本后，有一個新的監聽文件 endpoints_listener.ora 被引進，里面的內容是節點的 IP 和 VIP 信息。
Endpoints_listener.ora 文件的作用是向后兼容 11.2 版本以前的數據庫，DBCA 建庫時，需要通過獲取 endpoints 的位置信息來配置數據庫參數和 tnsnames，其中最下面兩行參數涉及 ENABLE_GLOBAL_DYNAMIC_ENDPOINT 參數，ENABLE_GLOBAL_DYNAMIC_ENDPOINT 參數的作用是允許監聽程序接受針對 oracle 11.2 版本之前未進行動態注冊的連接
（2）使用 srvctl 工具添加監聽并手動加入靜態注冊信息
– 添加監聽：（在 grid 用戶下執行）
[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 填入方才獲得的 network number，- p 填入端口號，- l 填入監聽名，-o 填入 GI HOME 路徑
– 執行：
[grid@dbrac2 admin]$ srvctl add listener -l LISTENER_wang -o $ORACLE_HOME -p 1522 -k 1
[grid@dbrac2 admin]$
– 查詢監聽狀態：
[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]$
– 啟動監聽：
[grid@dbrac2 admin]$ srvctl start listener -l LISTENER_wang
[grid@dbrac2 admin]$
– 查看新建的監聽狀態：

– 之后僅需要加入靜態注冊信息即可, 如:

(SID_LIST =
(SID_DESC =

(ORACLE_HOME = /oracle/app/11.2.0/grid)

)
加入如上信息到 listener.ora 配置文件中 (SID_LIST_($LISTENER_NAME)，并重啟監聽即完成靜態注冊：
[grid@dbrac2 admin]$ srvctl status listener -l LISTENER_WANG
Listener LISTENER_WANG is enabled
Listener LISTENER_WANG is running on node(s): dbrac1,dbrac2
[grid@dbrac2 admin]$
