Oracle 11g logminer实验

创建目录:mkdir -p /home/Oracle/logmnr

将归档打开,可以为后面的归档分析实验做准备。

安装三个包:

dbmslm.sql

dbmslmd.sql

dbmslms.sql

完毕后,设置utl_file_dir

alter system set utl_file_dir = '/home/oracle/logmnr' scope=spfile;

重启生效

创建数据字典:

begin

dbms_logmnr_d.build(

dictionary_filename=>'logminer_dict.dat',

dictionary_location=>'/home/oracle/logmnr');

end;

/

现在可以创建列表了:

execute dbms_logmnr.add_logfile(options=>dbms_logmnr.new,logfilename=>'/home/oracle/app/oracle/oradata/bdlms/redo11.log');

添加:

execute dbms_logmnr.add_logfile(options=>dbms_logmnr.new,logfilename=>'/home/oracle/app/oracle/oradata/bdlms/redo21.log');

此时可以查看v$logmnr_logs

启用日志分析:

begin

dbms_logmnr.start_logmnr(

dictfilename=>'/home/oracle/logmnr/logminer_dict.dat'

);

end;

/

也可以限制条件:

begin

dbms_logmnr.start_logmnr(

dictfilename=>'/home/oracle/logmnr/logminer_dict.dat',

starttime =>to_date('2012-01-01 16:40:23','YYYY-MM-DD HH24:MI:SS'),

endtime =>to_date('2012-01-02 16:40:00','YYYY-MM-DD HH24:MI:SS')

);

end;

/

观察分析结果:

select sql_redo from v$logmnr_contents;

也可以把此结果保存起来:

create table log_backup as select * from v$logmnr_contents;

最后停掉日志分析:

execute dbms_logmnr.end_logmnr();
