1.創建dbms_logmnr包
sql>@$oracle_home/rdbms/admin/dbmslm.sql
2.創建相關數據字典
sql>@$oracle_home/rdbms/admin/dbmslmd.sql
3.修改初始化參數utl_file_dir,指定分析數據的存放處
sql>alter system set utl_file_dir='/opt/oracle/logminer' scope=spfile;
4.重啟數據庫
sql>shutdown immediate
sql>startup
5.創建數據字典文件
sql>execute dbms_logmnr_d.build(dictionary_filename =>'sqltrace.ora',dictionary
_location =>'/opt/oracle/logminer/log');
6.建立日志分析表
sql> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.new,logfilename =>'/opt/oracle/ora92/rdbms/arc00009.001');
7.添加用于分析的日志文件
sql> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.addfile,logfilename=>'/opt/oracle/ora92/rdbms/arc00010.001');
sql> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.addfile,logfilename =>/opt/oracle/ora92/rdbms/arc00011.001');
刪除
sql> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.removefile,logfilenam
e =>'/opt/oracle/ora92/rdbms/arc00011.001');
8.啟動logminer進行分析
sql> execute dbms_logmnr.start_logmnr(dictfilename =>'/opt/oracle/logminer/log/sqltrace.or
a',starttime =>to_date('20040625 09:00:00','yyyymmdd hh24:mi:ss'),endtime =>to_d
ate('20040625 22:00:00','yyyymmdd hh24:mi:ss'));
9.參看分析結果
select operation,sql_redo,sql_undo from v$logmnr_contents;
10.結束分析
sql> execute dbms_logmnr.end_logmnr;
一旦結束視圖v$logmnr_contents中的分析結果也隨之不再存在。
