一、背景
oracle监听日志文件大小达到4G，不会往监听日志文件中写入新的日志，此时就要对监听日志进行清除。
二、清除监听日志
oracle的监听日志目录：
/u01/app/oracle/diag/tnslsnr/node01/listener/trace（node01是主机名）
1.查看监听状态
\[oracle@node01 listener\]$ lsnrctl status

监听状态是开启的，需要注意的是监听处于开启状态是不可以修改监听日志文件名或者删除监听日志文件的。
2.清除监听日志的方法
方法一、关闭监听清除监听日志
- 1.关闭监听
\[oracle@node01 listener\]$ lsnrctl stop

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=node01)(PORT=1521)))
The command completed successfully
- 2.清除监听日志
\[oracle@node01 trace\]$ rm -rf listener.log
也可以备份监听日志文件，然后再删除原有监听日志文件
\[oracle@node01 trace\]$ mv listener.log listener.log.bak
\[oracle@node01 trace\]$ ll
\-rw-r-----. 1 oracle oinstall 106920 Aug 19 03:24 listener.log.bak
- 3.重新开启监听
\[oracle@node01 trace\]$ lsnrctl start

方法二、不关闭监听清除监听日志
- 1.查看当前监听状态
\[oracle@node01 listener\]$ lsnrctl
