使用Logmnr方法分析数据库日志

核心提示： 3、使用logMiner进行日志分析1).无限制条件，即用数据字典文件对要分析的日志文件所有内容做分析SQL> execute dbms_logmnr.start_logmnr(DictFileName => 'G:oraclelogsdict.ora');PL

3、使用logMiner进行日志分析

1).无限制条件，即用数据字典文件对要分析的日志文件所有内容做分析

SQL> execute dbms_logmnr.start_logmnr(DictFileName => 'G:oraclelogsdict.ora');
PL/SQL procedure successfully completed

2).带限制条件，可以用scn号或时间做限制条件,也可组合使用

--分析日志列表中时间从07.02.28从10:00到15:00的内容

SQL> execute dbms_logmnr.start_logmnr(startTime => to_date('20070228100000','yyyy-mm-dd hh24:mi:ss'),endTime => to_date('20070228150000','yyyy-mm-dd hh24:mi:ss'),DictFileName => 'G:oraclelogsdict.ora');
PL/SQL procedure successfully completed
dbms_logmnr.start_logmnr函数的原型为：
PROCEDURE start_logmnr(
startScn INNUMBER default 0 ,
endScnINNUMBER default 0,
startTimeINDATE default '',
endTime INDATE default '',
DictFileNameINVARCHAR2 default '',
Options INBINARY_INTEGER default 0 );

4.分析后释放内存

SQL> execute dbms_logmnr.end_logmnr;

PL/SQL procedure successfully completed

5.其它

1).删除日志分析文件

exec dbms_logmnr.add_logfile('G:ORACLEORADATAORADBSPREDO04.LOG',dbms_logmnr.removefile);

三、查看LogMiner工具分析结果

SQL> select * from dict t where t.table_name like '%LOGMNR%';--看所有与logmnr相关的视图
