給11gR2 RAC添加LISTENER監聽器並靜態註冊
給11gR2 RAC添加LISTENER監聽器並靜態註冊
2011/12/04 by Maclean Liu 14 Commentshtml
以前有同窗想要給11gR2的RAC添加LISTENER監聽器，查看了listener.ora並發現問題:node
[oracle@vrh2 ~]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 04-DEC-2011 02:51:40 Copyright (c) 1991, 2011, Oracle. All rights reserved.

以上listener.ora配置文件中的信息是Grid Infrastructure安裝過程當中Agent自行添加的(During the Grid Infrastructure installation, the (default) node VIP listener is always created referencing the public network)，比較難以理解的多是LISTENER僅指定了PROTOCOL=IPC的信息， 而沒有指定監聽的地址、端口等信息。數據庫
實際上11.2 GI的LISTENER 監聽器配置默認受到11.2新引入的endpoints_listener.ora配置文件的管理：併發
Listener.ora [grid@netrac1 admin]$ more listener.ora LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2)))) # line added by Agent 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_SCAN2=ON # line added by Agent The ENABLE_GLOBAL_DYNAMIC_ENDPOINT_ parameter is set to allow the listener to accept connections for pre-11.2 databases which did not register the dynamic endpoint.

我一開始覺得LISTENER默認監聽的地址和端口被寫到了OCR中，後來用ocrdump轉儲註冊信息發現沒有相關記錄。 後來才發現原來11.2 GI中監聽器的地址和端口信息被移到了 endpoints_listener.ora中， 「Line added by Agent」說明是由Oraagent 進程更新的記錄。oracle
注意：使用 endpoints_listener.ora的狀況 下不該使用lsnrctl管理LISTENER，而需使用srvctl或crsctl工具管理，不然lsnrctl將不會識別endpoints_listener.ora中的信息，形成監聽沒有在必要地址、端口上工做。如：app

而在11.2 RAC中listener.ora僅記錄LISTENER的IPC條目。這樣作的目的是方便dbca配置數據庫參數及tnsnames.ora配置文件。tcp
瞭解到以上信息後可能你對當前11.2 RAC中的listener.ora文件中的監聽配置信息再也不感到奇怪。工具
咱們可使用netca圖形化工具或者srvctl 命令行工具添加監聽配置； 若是僅僅是手動在listener.ora中添加記錄的話是沒法被註冊爲Cluster Ready Service的服務的，將不會被CRS管理。this
方法1：spa
使用netca和netmgr圖形化工具，完成添加監聽和靜態註冊的工做。
1) 以Grid Infrastructure GI用戶登陸任意節點，並運行netca啓動圖形界面：
su - grid (grid)$ export DISPLAY=:0 (grid)$ netca
選擇LISTENER Configuration
選擇ADD
填入監聽名字
選擇subnet和availabe protocol ，通常默認便可，除非你有多個public network網段
填入端口號
選擇NO
選擇要啓動的監聽名，即方纔你建立的監聽名
以後選擇FINISH退出netca 界面，啓動netmgr界面，爲監聽加入靜態註冊的信息：
su - grid (grid)$ export DISPLAY=:0 (grid)$ netmgr
點選方纔建立的監聽器，選擇Database Services菜單
填入Global Database Name和本地實例的SID信息，並確認ORACLE HOME Directory(應是Grid Infrastructure的Home目錄)正確後點選Save Network Configuration。
以後使用srvctl 或 crsctl 重啓該監聽便可生效：
[grid@vrh1 admin]$ crsctl status res ora.MACLEAN_LISTENER.lsnr NAME=ora.MACLEAN_LISTENER.lsnr TYPE=ora.listener.type TARGET=ONLINE , ONLINE STATE=ONLINE on vrh1, ONLINE on vrh2 [grid@vrh1 admin]$ crsctl stop res ora.MACLEAN_LISTENER.lsnr CRS-2673: Attempting to stop 'ora.MACLEAN_LISTENER.lsnr' on 'vrh1' CRS-2673: Attempting to stop 'ora.MACLEAN_LISTENER.lsnr' on 'vrh2' CRS-2677: Stop of 'ora.MACLEAN_LISTENER.lsnr' on 'vrh1' succeeded CRS-2677: Stop of 'ora.MACLEAN_LISTENER.lsnr' on 'vrh2' succeeded [grid@vrh1 admin]$ crsctl start res ora.MACLEAN_LISTENER.lsnr CRS-2672: Attempting to start 'ora.MACLEAN_LISTENER.lsnr' on 'vrh2' CRS-2672: Attempting to start 'ora.MACLEAN_LISTENER.lsnr' on 'vrh1' CRS-2676: Start of 'ora.MACLEAN_LISTENER.lsnr' on 'vrh1' succeeded CRS-2676: Start of 'ora.MACLEAN_LISTENER.lsnr' on 'vrh2' succeeded [grid@vrh1 admin]$ lsnrctl status MACLEAN_LISTENER LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 27-NOV-2011 11:00:42 Copyright (c) 1991, 2011, Oracle.

以上使用netca和netmgr圖形界面工具完成了新監聽的添加和靜態註冊工做。
2. 使用srvctl 工具添加監聽並手動加入靜態註冊信息
檢查默認network的network number,紅色的數字
[grid@vrh1 admin]$ srvctl config network
Network exists: 1/192.168.1.0/255.255.255.0/eth0, type static
srvctl 添加監聽的語法以下
[grid@vrh1 admin]$ 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
[grid@vrh1 admin]$ srvctl add listener -l NEW_MACLEAN_LISTENER -o $CRS_HOME -p 1601 -k 1
-k 填入方纔得到的network number，-p填入端口號，-l填入監聽名，-o 填入GI HOME路徑
[grid@vrh1 admin]$ srvctl start listener -l NEW_MACLEAN_LISTENER
srvctl start listener啓動新添加的監聽後listener.ora和endpoints_listener.ora會出現新的記錄:
[grid@vrh1 admin]$ head -1 listener.ora NEW_MACLEAN_LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=NEW_MACLEAN_LISTENER)))) # line added by Agent [grid@vrh1 admin]$ head -1 endpoints_listener.ora NEW_MACLEAN_LISTENER_VRH1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=vrh1-vip)(PORT=1601)) (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.161)(PORT=1601)(IP=FIRST)))) # line added by Agent
以上已經完成了監聽的添加，足見使用srvctl管理更爲簡便。
以後僅須要加入靜態註冊信息便可,如:
SID_LIST_NEW_MACLEAN_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = VPROD)
(ORACLE_HOME = /g01/11.2.0/grid)
(SID_NAME = VPROD1)
)
)
加入如上信息到listener.ora配置文件中(SID_LIST_($LISTENER_NAME)，並重啓監聽即完成靜態註冊：
[grid@vrh1 admin]$ srvctl stop listener -l NEW_MACLEAN_LISTENER [grid@vrh1 admin]$ srvctl start listener -l NEW_MACLEAN_LISTENER [grid@vrh1 admin]$ lsnrctl status NEW_MACLEAN_LISTENER LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 27-NOV-2011 11:21:37 Copyright (c) 1991, 2011, Oracle.
