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 16:54:16Copyright (c) 1991, 2002, Oracle Corporation.

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_configConnecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC)))Saved LISTENER1 configuration parameters.Listener Parameter File /opt/oracle/product/9.2.0/network/admin/listener.oraOld Parameter File /opt/oracle/product/9.2.0/network/admin/listener.bakThe 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#----ADDED BY TNSLSNR 14-NOV-2006 16:39:12---LOG_FILE_LISTENER1 = a.log#-------------------------------------------- |
