使用"LogMiner"的具体步骤：
1.创建DBMS_LOGMNR包
SQL>@$ORACLE_HOME/rdbms/admin/dbmslm.sql |
2.创建相关数据字典
SQL>@$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 immediateSQL>startup |
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''); |
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''); |
删除:
SQL> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.removefile,logfilename =>''/opt/oracle/ora92/rdbms/ARC00011.001''); |
8.启动LogMiner进行分析
SQL> execute dbms_logmnr.start_logmnr(dictfilename =>''/opt/oracle/logminer/log/sqltrace.ora'',starttime =>to_date(''20040625 09:00:00'',''yyyymmdd hh24:mi:ss''),endtime =>to_date(''20040625 22:00:00'',''yyyymmdd hh24:mi:ss'')); |
9.参看分析结果
select operation,sql_redo,sql_undo from v$logmnr_contents; |
10.结束分析
SQL> execute dbms_logmnr.end_logmnr; |
注释：假如结束视图，v$logmnr_contents中的分析结果也将随之消失。
