监听日志存放的位置;

[oracle@www log]$ pwd
/u01/oracle/product/10.2.0/network/log 

[oracle@www log]$ ls -l
总计 32
-rw-r----- 1 oracle oinstall 30445 07-25 18:03 listener.log

日常维护中误删除监听日志，但是监听还能正常工作

那么我们测试监听日志被删除后，重新写入监听日志的一个过程

[oracle@www log]$ rm -rf listener.log -----------删除监听日志
[oracle@www log]$ ls
[oracle@www log]$ lsnrctl
