Listener log 概述

在ORACLE數據庫中，如果不對監聽日志文件（listener.log）進行截斷,那么監聽日志文件（listener.log）會變得越來越大.

Listener log location

For oracle 9i/10g

在下面的目錄下：

$ORACLE_HOME/network/log/listener_$ORACLE_SID.log

For oracle 11g/12c

在下面的目錄下：

$ORACLE_BASE/diag/tnslsnr/主機名稱/listener/trace/listener.log

或者通過 lsnrctl status 也可以查看位置

這里展示的是 xml格式的日志，跟.log并無區別。

或者11g可以通過 adrci 命令

Listener log日志文件清理

需要對監聽日志文件（listener.log）進行定期清理。
1：監聽日志文件（listener.log）變得越來越大，占用額外的存儲空間
2：監聽日志文件（listener.log）變得太大會帶來一些問題，查找起來也相當麻煩
3：監聽日志文件（listener.log）變得太大，給寫入、查看帶來的一些性能問題、麻煩

定期對監聽日志文件（listener.log）進行清理，另外一種說法叫截斷日志文件。

列舉一個錯誤的做法

oracle@entel2:[/oracle]$mv listener.log listener.log.20161201 oracle@entel2:[/oracle]$cp /dev/null listener.log oracle@entel2:[/oracle]$more listener.log

如上所示，這樣截斷監聽日志（listener.log）后，監聽服務進程（tnslsnr）并不會將新的監聽信息寫入listener.log，而是繼續寫入listener.log.20161201

正確的做法

1：首先停止監聽服務進程（tnslsnr）記錄日志。

oracle@entel2:[/oracle]$lsnrctl set log_status off

2：將監聽日志文件（listener.log）復制一份，以listener.log.yyyymmdd格式命名

oracle@entel2:[/oracle]$cp listener.log listener.log.20161201

3：將監聽日志文件（listener.log）清空。清空文件的方法有很多

oracle@entel2:[/oracle]$echo “” > listener.log 或者 oracle@entel2:[/oracle]$cp /dev/null listener.log 或者 oracle@entel2:[/oracle]$echo /dev/null > listener.log 或者 oracle@entel2:[/oracle]$>listener.log

4：開啟監聽服務進程（tnslsnr）記錄日志

oracle@entel2:[/oracle]$lsnrctl set log_status on

當然也可以移走監聽日志文件（listener.log），數據庫實例會自動創建一個listener.log文件。

oracle@entel2:[/oracle]$ lsnrctl set log_status offoracle@entel2:[/oracle]$mv listener.log listener.yyyymmddoracle@entel2:[/oracle]$lsnrctl set log_status on

清理shell腳本

當然這些操作應該通過shell腳本來處理，然后結合crontab作業定期清理、截斷監聽日志文件。

簡單一點的（核心部分）

rq=` date +"%d" ` cp $ORACLE_HOME/network/log/listener.log $ORACLE_BACKUP/network/log/listener_$rq.log su - oracle -c "lsnrctl set log_status off" cp /dev/null $ORACLE_HOME/network/log/listener.log su - oracle -c "lsnrctl set log_status on"

這樣的腳本還沒有解決一個問題，就是截斷的監聽日志文件保留多久的問題。比如我只想保留這些截斷的監聽日志一個月時間，我希望作業自動維護。不需要我去手工操作。有這樣一個腳本cls_oracle.sh可以完全做到這個，當然它還會歸檔、清理其它日志文件，例如告警文件（alert_sid.log）等等。功能非常強大。
