本篇文章小编给大家分享一下处理Oracle监听文件listener.log问题实例,小编觉得挺不错的,现在分享给大家供大家参考,有需要的小伙伴们可以来看看。
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。
