假如你的数据库的监听器日志出了问题，你可以用set log_file命令重新定位一个日志文件得来解决此问题。

你可以参考以下两个命令:

LSNRCTL> set current_listener <listener name>
LSNRCTL> set log_file <sid name>.log

注释：set current_listener命令可以访问非缺省监听器，当你使用set log_file命令更改名称以后，原来有问题的日志文件则可以清除或实现日志重定位：

[oracle@jumper admin]$ lsnrctl

LSNRCTL for Linux: Version 9.2.0.4.0 - Production on 10-NOV-2006 16:54:16

Welcome to LSNRCTL, type "help" for information.

LSNRCTL> set current_listener LISTENER1
Current Listener is LISTENER1
LSNRCTL> set log_file
Parameter Value: a.log
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
LISTENER1 parameter "log_file" set to a.log
The command completed successfully
LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
STATUS of the LISTENER
------------------------
Alias                     LISTENER1

Uptime                    0 days 0 hr. 2 min. 6 sec
Trace Level               off

Listener Parameter File   /opt/oracle/product/9.2.0/network/admin/listener.ora
Listener Log File         /opt/oracle/product/9.2.0/network/log/a.log
Listening Endpoints Summary...

假如你需要将这个修改永久化，你可以使用save_config命令来保存。

LSNRCTL> save_config
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))
Saved LISTENER1 configuration parameters.
Listener Parameter File /opt/oracle/product/9.2.0/network/admin/listener.ora
Old Parameter File /opt/oracle/product/9.2.0/network/admin/listener.bak
The command completed successfully

此时，listener.ora文件会被增加以下的记录：

[oracle@jumper oracle]$ tail -5 /opt/oracle
/product/9.2.0/network/admin/listener.ora
