如果你的数据库监听器日志出现了问题，你可以用set log_file命令重新定位一个日志文件。
下面我们来介绍两个命令:
LSNRCTL> set current_listener
LSNRCTL> set log_file .log |
注释：使用set current_listener可以访问非缺省监听器，使用set log_file更改名称后，原来有问题的日志文件可以清除或实现日志重定位:
oracle@jumper admin]$ lsnrctl

加入你需要将此修改永久化，你需要使用save_config命令来保存一下：
LSNRCTL> save_config
Connecting to (DESCRIPTION=
(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
Saved LISTENER1 configuration parameters.

至此listener.ora文件会被增加如下记录：
[oracle@jumper oracle]$ tail -5 /opt/oracle
/product/9.2.0/network/admin/listener.ora
#----ADDED BY TNSLSNR 14-NOV-2006 16:39:12---
