listenora.ora默认保存位置是/u01/app/oracle/product/11.2.0/db_1/network/admin
现通过TNS_ADMIN环境变量来从重定向监听文件位置；
将监听配置文件listener.ora复制到/u02/data目录下，原位置listenor.ora文件重命名或删除；

设置环境变量：
[oracle@OL541 admin]$ echo $TNS_ADMIN
默认为空
[oracle@OL541 ~]$ export TNS_ADMIN=/u02/data/.
[oracle@OL541 ~]$ echo $TNS_ADMIN
/u02/data/.

启动监听：
[oracle@OL541 ~]$ lsnrctl start

从上述输出日志可看出监听文件启动位置变化了。
