Oracle RAC下添加静态注册监听器listener
通过设置不同的listener，可以在一台服务器多实例c环境下实现业务的隔离，方便业务起停和管理。添加的方法除了netca外，比较简单的方式是使用srvctl命令，具体用法如下
[grid@dtydb5 ~]$ 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
具体过程如下，数据库是oracle 11gr2版本
1，开始添加 ，使用grid用户
[grid@dtydb5 admin]$ srvctl add listener -l listener_epm -p 1522 -o $ORACLE_HOME
2，启动
srvctl start listener -l listener_epm
启动后相关文件才发生变化
[grid@dtydb5 admin]$ cat listener.ora

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

[grid@dtydb5 admin]$
[grid@dtydb5 admin]$
[grid@dtydb5 admin]$
[grid@dtydb5 admin]$ cat endpoints_listener.ora

The listener supports no services
The command completed successfully
4,vi listener.ora 添加以下信息，主要要修改三个节点的信息（后来证实，本步骤可以省略，可能因为静态监听信息已在endpoints_listener.ora文件中了）
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, 重启listener
[grid@dtydb5 admin]$ srvctl stop listener -l listener_epm
[grid@dtydb5 admin]$ srvctl start listener -l listener_epm
这时服务还是没有注册上来
[grid@dtydb5 admin]$ lsnrctl status listener_epm

6,什么原因？应该是local_listener设置问题,还需要修改该参数
sys@EPMDB3(dtydb5)> show parameter local

local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=10.4

系统已更改。
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';
