今天在测试机上, 误删除listener.log,重建后居然没有内容写进来,

执行：

 $ Lsnrctl status

发现正常

$ lsnrctl

>Show log_file

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=mant)(PORT=1521)))

LISTENER parameter "log_file" set to listener.log

The command completed successfully

>show log_status

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=mant)(PORT=1521)))

LISTENER parameter "log_status" set to ON

The command completed successfully

很是郁闷了一会儿 。

> set log_status off ;

> set log_status on;

再观察listener.log，已经有记录了 ！
