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
