嘗試各種方法都沒搞定，偵聽啟動和停止都特別慢。
查看監聽日誌的大小，位置如下：
$ORACLE_BASE\diag\tnslsnr\<hostname>\listener\trace\listener.log——4G大小
出現該BUG問題的平臺
Oracle Net Services - Version 11.1.0.7 to 11.2.0.4 [Release 11.1 to 11.2]
Microsoft Windows (32-bit)
Microsoft Windows x64 (64-bit)
This issue is limited to the Windows OS.
Checked for relevance on 14-OCT-2013
解決方法：關閉監聽寫日誌
腳本：
LSNRCTL>set current_listener <listener_name>
LSNRCTL>set log_status OFF
或者，，重命名listener.log，然後重啟服務，好了。。。。。開心。。。
