处理Oracle 监听文件listener.log问题

如果连接时候变得较慢 查看Oracle日志记录，可能是因为此文件太大，超过2G，
需要定期清理，（如果多用户，记得用root，可能没权限）
查看listener.log？
find / -name listener.log
经查看，竟然高达2G得日志数据，由于一些老旧的OS不支持2GB以上的文件，故当listener.log文件
超过2GB时，会出现无法处理新的连接，新的操作系统虽然不会出现这个问题，但我们依然需要对其
进行定期处理清理。
Listener log日志文件处理
[oracle@localhost home]$ lsnrctl LSNRCTL> set log_status off Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) LISTENER parameter "log_status" set to OFF The command completed successfully LSNRCTL> show log_status Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) LISTENER parameter "log_status" set to OFF The command completed successfully LSNRCTL> exit [oracle@localhost home]$ find -name listener.log home/oracle/app/oracle/diag/tnslsnr/localhost/listener/trace/listener.log [oracle@localhost ~]$ cd /home/oracle/app/oracle/diag/tnslsnr/localhost/listener/trace/ [oracle@localhost trace]$ mv listener.log listener.log.20191127 [oracle@localhost trace]$ ls listener.log.20191127 ora_2617_140154513196800.trc [oracle@localhost trace]$ lsnrctl LSNRCTL> set log_status on Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) LISTENER parameter "log_status" set to ON The command completed successfully LSNRCTL> show log_status Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) LISTENER parameter "log_status" set to ON The command completed successfully LSNRCTL> reload Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) The command completed successfully LSNRCTL> exit [oracle@localhost trace]$

我们通过重命名日志文件之后，会自动生成一个新的listener.log文件。当然也可以进行清空处理，可以先copy一下备份，然后进行清空处理。
总结
