要對監聽記錄檔（listener.log）進行定期清理，如果不定期清理，會遇到下面一些麻煩：

     1：監聽記錄檔（listener.log）變得越來越大，佔用額外的儲存空間。（當然現在儲存白菜價，不差那幾G的空間。但是我們還是要本著工匠情懷，精益求精）     2：監聽記錄檔（listener.log）變得太大會帶來一些問題：LISTENER.LOG日誌大小不能超過2GB，超過會導致LISTENER監聽器無法處理新的串連。     3：監聽記錄檔（listener.log）變得太大，給寫入、查看帶來的一些效能問題、麻煩。  另：監聽日誌listener.log日誌放在了$ORACLE_BASE/diag/tnslsnr/機器名/listener/trace目錄下  日誌內容如下參考：
