Oracle 的listener.log 日志超过4G导致SQL速度极慢，监听命令能执行要10min。

查看上面的alter日志可以一个问题就是【TNS-12570: TNS: 包阅读程序失败】

找了好久都没有什么头绪，结果看到$ORACLE_HOME/diag\tnslsnr\WIN-LO2BM3SDT1A\listener\trace 目录下

有一个listener.log 日志文件大小到4G多，找了下windows 文件系统的配置如下，这个文件明显达到极限（客户服务器为NTFS 64位 txt文件可以支持到4G），

Windows下可以使用下面的命令来控制

lsnrctl set log_status off

rename listener.log listener.old

lsnrctl set log_status on

理论上硬盘还剩多少就可以保存多大的文件

NTFS（Windows）：支持最大分区2TB，最大文件2TB

FAT16（Windows）：支持最大分区2GB，最大文件2GB

FAT32（Windows）：支持最大分区128GB，最大文件4GB

HPFS（OS/2）：支持最大分区2TB，最大文件2GB

EXT2和EXT3（Linux）：支持最大分区4TB，最大文件2GB

JFS（AIX）：支持最大分区4P（block size=4k），最大文件4P

XFS（IRIX）：这是个正经的64位的文件系统，可以支持9E（2的63次方）的分区
