oracle rac下添加靜态注冊監聽器listener

通過設定不同的listener，可以在一台伺服器多執行個體c環境下實作業務的隔離，友善業務起停和管理。添加的方法除了netca外，比較簡單的方式是使用srvctl指令，具體用法如下

[[email protected] ~]$ srvctl add listener -h

Adds a listener configuration to the Oracle Clusterware.

Usage: srvctl add listener [-l <lsnr_name>] [-s] [-p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]"] [-o <oracle_home>] [-k <net_num>]

-l <lsnr_name> Listener name (default name is LISTENER)

-o <oracle_home> ORACLE_HOME path (default value is CRS_HOME)

-k <net_num> network number (default number is 1)

-s Skip the checking of ports

-p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]" Comma separated tcp ports or listener endpoints

-h Print usage

具體過程如下，資料庫是oracle 11gr2版本

1，開始添加 ，使用grid使用者

[[email protected] admin]$ srvctl add listener -l listener_epm -p 1522 -o $ORACLE_HOME

2，啟動

srvctl start listener -l listener_epm

啟動後相關檔案才發生變化

[[email protected] admin]$ cat listener.ora

LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent

The listener supports no services

The command completed successfully

4,vi listener.ora 添加以下資訊，主要要修改三個節點的資訊（後來證明，本步驟可以省略，可能因為靜态監聽資訊已在endpoints_listener.ora檔案中了）

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = epmdb)

(ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db_1)

(SID_NAME = epmdb3)

)

)

5, 重新開機listener

[[email protected] admin]$ srvctl stop listener -l listener_epm

[[email protected] admin]$ srvctl start listener -l listener_epm

這時服務還是沒有注冊上來

[[email protected] admin]$ lsnrctl status listener_epm

6,什麼原因？應該是local_listener設定問題,還需要修改該參數

[email protected](dtydb5)> show parameter local

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD

DRESS=(PROTOCOL=TCP)(HOST=10.4

.124.245)(PORT=1521))))

[email protected](dtydb5)> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.4.124.245)(PORT=1522))))' scope=both sid='*';

系統已更改。

alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.4.124.243)(PORT=1522))))' scope=both sid='epmdb1';

alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.4.124.244)(PORT=1522))))' scope=both sid='epmdb2';

alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.4.124.245)(PORT=1522))))' scope=both sid='epmdb3';

7，已成功注冊
