Oracle 监听器日志配置与管理

本文主要描述对Oracle监听器日志文件的配置与管理。有关监听器的描述请参考

    配置非默认端口的动态服务注册    

一、监听器日志特性

1.  监听器日志是一个纯文本文件，通常位于$ORACLE_HOME/network/log目录下，与sqlnet.log日志文件处于同一路径            
2.  其缺省的文件名为listener.log。对于非缺省的监听器，则产生的日志文件通常为listenername.log                        
3.  该文件缺省由监听器自动创建，当日志文件丢失时或不存在时，会自动重新创建一个同名的文件，与alert_<SID>.log文件类似 
4.  该文件的尺寸会不断自动增长，当尺寸过大时或不便于阅读时，考虑将其备份                                            
5.  Oracle监听器在运行时不允许对日志文件做删除，重命名操作                                                          
6.  可以设置日志状态为ON或OFF来实现启用或关闭日志     

二、设置日志文件目录及路径

       1.  设置日志文件目录的两种方法        

[sql] view plain copy

 print?

1. lsnrctl SET LOG_DIRECTORY directory  
2.           
3. LSNRCTL> SET LOG_DIRECTORY /usr/oracle/admin/log  

[sql] view plain copy

 print?

1. lsnrctl SET LOG_FILE file_name  
2.          
3. LSNRCTL> SET LOG_FILE file_name  

[sql] view plain copy

 print?

1. lsnrctl SET LOG_STATUS {on | off}  
2.   
3. LSNRCTL> SET LOG_STATUS {on | off}

 print?

1. C:/>cd /oracle/ora92/network/log     -->切换到监听器日志文件所在目录                                           
2. C:/oracle/ora92/network/log> lsnrctl set log_status off -->暂停或脱机记录日志文件                              
3. C:/oracle/ora92/network/log> rename listener.log listener.old -->重命名日志文件，一般加上日期                  
4. C:/oracle/ora92/network/log> lsnrctl set log_status on -->联机监听器日志文件，会自动重新创建一个新的日志文件   

[sql] view plain copy

 print?

1. $ lsnrctl set log_status off                                                                               
2. $ mv listener.log listener.old -->另一种方法，cp listener.log /log/bak/. 然后 cp /dev/null >listener.log   
3. $ lsnrctl set log_status on                                                                                    

[sql] view plain copy

 print?

1. [oracle@test ~]$ cd /home/oracle/log                                                      
2. [oracle@test log]$ lsnrctl set log_status off  -->如果存在密码，应使用LSNRCTL界面来完成   
3.
