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 |
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 LSNRCTL for Linux: Version 9.2.0.4.0 - Production on 10-NOV-2006 16:54:16 Copyright (c) 1991, 2002, Oracle Corporation. All rights reserved. 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 Version TNSLSNR for Linux: Version 9.2.0.4.0 - Production Start Date 10-NOV-2006 16:54:12 Uptime 0 days 0 hr. 2 min. 6 sec Trace Level off Security OFF SNMP 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...

Service "eygle" has 1 instance(s). Instance "eygle", status UNKNOWN, has 1 handler(s) for this service... The command completed successfully 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. 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 |
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--- LOG_FILE_LISTENER1 = a.log #---------------------------------- |
