使用"LogMiner"的具体步骤：
1.创建DBMS_LOGMNR包
SQL>@$ORACLE_HOME/rdbms/admin/dbmslm.sql 数据挖掘交友
|
2.创建相关数据字典
SQL>@$ORACLE_HOME/rdbms/admin/dbmslmd.sql
|
3.修改初始化参数UTL_FILE_DIR,指定分析数据的存放处
SQL>alter system set UTL_FILE_DIR=""/opt/oracle/logminer"" scope=spfile;
|
4.重启数据库
SQL>shutdown immediate
SQL>startup 数据挖掘工具
|
5.创建数据字典文件
SQL>execute dbms_logmnr_d.build
(dictionary_filename =>""sqltrace.ora"",dictionary
_location =>""/opt/oracle/logminer/log""); 数据挖掘实验室
|
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""); 数据挖掘交友
|
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""); 数据挖掘研究院
|
删除:
SQL> execute dbms_logmnr.add_logfile
(options =>dbms_logmnr.removefile,logfilenam
e =>""/opt/oracle/ora92/rdbms/ARC00011.001""); 数据挖掘研究院
|
8.启动LogMiner进行分析
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_date
(""20040625 22:00:00"",""yyyymmdd hh24:mi:ss"")); 数据挖掘交友
|
9.参看分析结果
select operation,sql_redo,sql_undo from v$logmnr_contents; 数据挖掘论坛
|
10.结束分析
SQL> execute dbms_logmnr.end_logmnr; 数据挖掘实验室
|
注释：如果结束视图，v$logmnr_contents中的分析结果也将随之消失。
