认真就输

昨晚群里一个兄弟问他们一体机环境，监听日志文件没有写到XML文件，并且listener.log中也没有写日志文件。

监听状态如下：

部分敏感信息已经被替换
[grid@www.htz.pw ~]$ lsnrctl status

这里可以看到监听日志位置到$ORACLE_HOME/network/log位置，而非adr目录，并且listener.log修改时候是在6月份。

1，11G监听文件位置

11G环境中，监听文件默认存放在adr目录中，并且存放2份，一份xml格式，一份文本格式，如下：

xml位置
[oracle@www.htz.pw sql]$lsnrctl status|grep "Log File"
Listener Log File         /oracle/app/oracle/diag/tnslsnr/orcl9i/listener/alert/log.xml
文件格式位置
[oracle@www.htz.pw sql]$ls -l $ORACLE_BASE/diag/tnslsnr/`hostname`/listener/trace/listener.log
-rw-r-----  1 oracle oinstall 1973762 Sep  3 06:22 /oracle/app/oracle/diag/tnslsnr/orcl9i/listener/trace/listener.log

1.1 禁用监听日志的adr功能

[oracle@www.htz.pw sql]$ps -ef|grep lsn

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = /oracle/app/oracle

DIAG_ADR_ENABLED_LISTENER=off

再次加载监听

[oracle@www.htz.pw sql]$lsnrctl reload

Listener Log File         /oracle/app/oracle/product/11.2.0/db_1123/network/log/listener.log

看到监听日志文件路径已经回到10G的默认的方式，存放$ORACLE_HOME/network/admin/log下面

1.2 修改监听日志文件名与路径

有时由于空间原因，需要修改监听日志文件名与路径的位置，下面将日志文件路径名修改到/tmp，文件名修改为www.htz.pw，文件名自动增加.log结尾

增加参数到listener.ora中
[oracle@www.htz.pw sql]$echo "LOG_DIRECTORY_LISTENER=/tmp">>$ORACLE_HOME/network/admin/listener.ora
[oracle@www.htz.pw sql]$echo "LOG_FILE_LISTENER=www.htz.pw">>$ORACLE_HOME/network/admin/listener.ora
[oracle@www.htz.pw sql]$cat !$
cat $ORACLE_HOME/network/admin/listener.ora

    )
  )

ADR_BASE_LISTENER = /oracle/app/oracle

LOG_DIRECTORY_LISTENER=/tmp

重新加载监听

这里看到监听文件名与路径都已经修改了

2 监听日志文件中无新日志生成

通过监听登陆数据库，都会向监听日志文件写日志，并且使用动态监听，pmon进程会将动态注册的信息写到监听日志文件中去。常常遇到监听日志文件中无新内容，一般情况下是：

1，日志文件达到4G，部分OS达到4G后，不会向监听日志文件写新的内容。

2，无新连接，可以通过lsnrctl service来查看

在这位兄弟的情况就是日志达到4G的大小

[grid@www.htz.pw ~]$ ls -l /u01/app/grid/network/log/listener.log
-rw-r----- 1 grid oinstall 4294967366 Aug  6 16:37 /u01/app/grid/network/log/listener.log

3 清理日志文件

[oracle@www.htz.pw tmp]$lsnrctl
