监听日志太大，如何删除？

1.先去监听日志的目录里面并查看大小

        cd $ORACLE_HOME/network/log/
        du -sh *

2.到listener里面，查看对应的log_file和log_status

    [oraarp@localhost log]$ lsnrctl
    LSNRCTL> show log_file
    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521)))
    LISTENER parameter "log_file" set to listener.log
    The command completed successfully
    LSNRCTL> show log_status
    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521)))
    LISTENER parameter "log_status" set to ON
    The command completed successfully

3.现在可以关闭listener log

    LSNRCTL> set log_status off
    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521)))
    LISTENER parameter "log_status" set to OFF
    The command completed successfully

4.然后mv以前的日志文件

    [oraarp@localhost log]$ mv listener.log listener.log.bak
    

5.再开启listerer log

    LSNRCTL> set log_status on
    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521)))
    LISTENER parameter "log_status" set to ON
    The command completed successfully

   这个时候，就会产生一个新的默认名字为listener.log日志。这个时候你就可以删除以前的log日志了。
