oracle logminer

第一步：首先在spfile中添加一下内容：

SQL> alter system set UTL_FILE_DIR = 'd:/search' scope = spfile;（目录可以是任意位置）

SQL> shutdown immediate;

SQL> startup;



第二步：创建字典文件：

EXECUTE   dbms_logmnr_d.build(dictionary_filename=>'sqltrace.ora',dictionary_location=>'d:/search');

第三步：将待查询内容的日志文件添加到字典中去

exec dbms_logmnr.add_logfile(options =>dbms_logmnr.new, logfilename =>'E:\oracle_data\oradata\testdb\redo01.log');

如果还要添加日志文件，则将DBMS_LOGMNR.NEW改为DBMS_LOGMNR.ADDFILE;

exec dbms_logmnr.add_logfile(options => dbms_logmnr.addfile, logfilename =>'E:\oracle_data\oradata\testdb\redo02.log');

exec dbms_logmnr.add_logfile(options => dbms_logmnr.addfile, logfilename =>'E:\oracle_data\oradata\testdb\redo03.log');


第四步：分析数据

exec dbms_logmnr.start_logmnr(DictFileName=>'d:/search/sqltrace.ora');

第五部：查看内容

select username, sql_redo, sql_undo from v$logmnr_contents where username ='sys' and peration ='select';
