11g R2 rac linstener 监听配置

两个节点host,ipvip ,scan的信息 #eth0-Public IP 162.12.0.1    cqltjcpt1 162.12.0.3    cqltjcpt2   #eth1 PRIVATE IP 192.12.0.1   cqltjcpt1-prvi 192.12.0.3   cqltjcpt2-prvi   #VIP 162.12.0.5   cqltjcpt1-vip 162.12.0.7   cqltjcpt2-vip   #SCAN 162.12.0.9   cqltjcptscan       11G rac中，监听文件默认配置在grid用户下   [root@cqltjcpt2 ~]# su - grid [grid@cqltjcpt2 ~]$ cd $ORACLE_HOME [grid@cqltjcpt2 grid]$ cd network/admin/ [grid@cqltjcpt2 admin]$ ll   -rw-r--r-- 1 grid oinstall  189 Jan  7 21:21 endpoints_listener.ora -rw-r--r-- 1 grid oinstall  350 Jan  7 21:21 listener.ora drwxr-xr-x 2 grid oinstall 4096 Jan  7 21:04 samples -rw-r--r-- 1 grid oinstall  205 May 11  2011 shrept.lst -rw-r--r-- 1 grid oinstall  227 Jan  7 21:21 sqlnet.ora   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     [grid@cqltjcpt2 admin]$ more endpoints_listener.ora LISTENER_CQLTJCPT2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP) (HOST=cqltjcpt2-vip)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=162.12.0.3)(PORT=1521)(IP=FIRST))))                  由于用hosts解析配置本例中没有配置DNS，只有一个scan listener 此时scan监听只运行在Node1上   [grid@cqltjcpt2 admin]$ ps -ef | grep tnslsnr grid      9840     1  0 Jan07 ?        00:00:22 /u01/oracle/grid/bin/tnslsnr LISTENER -inherit grid     22674 21922  0 11:08 pts/1    00:00:00 grep tnslsnr   [grid@cqltjcpt2 ~]$ ssh cqltjcpt1 [grid@cqltjcpt1 ~]$ ps -ef | grep  tnslsnr grid      8211     1  0 Jan07 ?        00:00:44 /u01/oracle/grid/bin/tnslsnr LISTENER -inherit grid      8380     1  0 Jan07 ?        00:00:02 /u01/oracle/grid/bin/tnslsnr LISTENER_SCAN1 -inherit grid     22060 22021  0 11:08 pts/1    00:00:00 grep tnslsnr   从ps -ef输出可以看到，无论是scan监听，还是本地监听都是运行在grid用户的oracle_home下     NODE2本地监听指向的是vip地址162.12.0.7 ，因为rac是通过vip对外提供服务     [oracle@cqltjcpt2 ~]$ sqlplus  / as sysdba   SQL> show parameter local_listener   NAME            TYPE        VALUE --------------- ---------- -------------------------------------------------------------------------------- local_listener  string      (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=162.12.0.7)(PORT=1521))))   remote_listener指向的是scan监听名   SQL> show parameter remote_listener                NAME               TYPE         VALUE -----------------  -----------  ------------------------------ remote_listener    string       cqltjcptscan:1521     切换至grid用户   [root@cqltjcpt2 ~]# su - grid [grid@cqltjcpt2 ~]$ cd $ORACLE_HOME/network/admin [grid@cqltjcpt2 admin]$ ls endpoints_listener.ora  listener.ora    samples  shrept.lst  sqlnet.ora   查看监听文件内容 [grid@cqltjcpt2 admin]$ more listener.ora   LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1))))                    LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))))                ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON                  ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON                     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     查看监听状态，可以看到cqltgsqz2实例已经运行 [grid@cqltjcpt2 ~]$ srvctl  status listener Listener LISTENER is enabled Listener LISTENER is running on node(s): cqltjcpt1,cqltjcpt2     [grid@cqltjcpt2 ~]$ lsnrctl status listener   LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 08-JAN-2013 10:58:30   Copyright (c) 1991, 2011, Oracle.  All rights reserved.   Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))) STATUS of the LISTENER ------------------------ Alias                     LISTENER Version                   TNSLSNR for Linux: Version 11.2.0.3.0 - Production Start Date                07-JAN-2013 22:44:03 Uptime                    0 days 12 hr. 14 min. 26 sec Trace Level               off Security                  ON: Local OS Authentication SNMP                      OFF Listener Parameter File   /u01/oracle/grid/network/admin/listener.ora Listener Log File         /u01/oracle/app/oracle/diag/tnslsnr/cqltjcpt2/listener/alert/log.xml Listening Endpoints Summary...   (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=LISTENER)))   (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=162.12.0.3)(PORT=1521)))   (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=162.12.0.7)(PORT=1521))) Services Summary...
