第一种方法使用联机目录分析归档日志
1、打开数据库的追加日志(这个一定要注意了,否则分析出来的都是ddl)
---10g特性,不然无法查出dml操作的数据
SELECT SUPPLEMENTAL_LOG_DATA_MIN FROM V$DATABASE;
如果结果为YES就不需要追加日志反之,
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
2、切换日志,然后执行事务删除.
CONN / AS SYSDBA
ALTER SYSTEM SWITCH LOGFILE;
CONNECT TEST/TEST
DELETE FROM TEST1 WHERE ID=1;
COMMIT;
CONN / AS SYSDBA
ALTER SYSTEM SWITCH LOGFILE;
SELECT NAME FROM V$ARCHIVED_LOG;
3、将新生成的日志文件添加到LOGMINER列表中。
EXECUTE DBMS_LOGMNR.ADD_LOGFILE (-
'C:oracleproduct10.2.0flash_recovery_areaTESTARCHIVELOG2007_10_31O1_MF_1_72_3LHVWNOZ_.ARC',-
DBMS_LOGMNR.NEW);
4、为LOGMINER指定将要使用的联机目录。如果源数据库处于打开或者是可用状态,那么它也可用。
EXECUTE DBMS_LOGMNR.START_LOGMNR(-
PTIONS => DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG);
5、在V$LOGMNR_CONTENTS中查询有关删除事务的信息。
SELECT USERNAME,SQL_REDO,SQL_UNDO FROM
V$LOGMNR_CONTENTS WHERE USERNAME='TEST'
AND PERATION='DELETE';

已选择6行。
6、结束LOGMNR
execute dbms_logmnr.end_logmnr;
----------------------------------------------------------------------
第二种方法使用LOGMINER字典
1、首先修改参数文件
添加UTL_FILE_DIR=c:log_miner
2、以sys用户运行脚本,创建数据字典文件
SQL> execute dbms_logmnr_d.build('testtrace.ora', 'c:log_miner',dbms_logmnr_d.store_in_flat_file);
PL/SQL 过程已成功完成。
3、建立日志分析表,使用dbms_logmnr.add_logfile()
SQL> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.new,logfilename=>'C:oracleproduct10.2.0flash_recovery_areaTESTARCHIVELOG2007_10_31O1_MF_1_72_3LHVWNOZ_.ARC');
PL/SQL 过程已成功完成。
4、添加用于分析的日志文件
SQL> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.addfile,logfilename =>'C:oracleproduct10.2.0flash_recovery_areaTESTARCHIVELOG2007_10_31O1_MF_1_73_3LHZO54W_.ARC');
execute dbms_logmnr.add_logfile(options =>dbms_logmnr.addfile,logfilename =>'C:oracleproduct10.2.0flash_recovery_areaTESTARCHIVELOG2007_10_31O1_MF_1_71_3LHVOK7B_.ARC');
PL/SQL 过程已成功完成。
5、启动LogMiner进行分析。
SQL> execute dbms_logmnr.start_logmnr(dictfilename =>'c:log_minertesttrace.ora',starttime =>to_date-('20071031 09:00:00','yyyymmdd hh24:mi:ss'),endtime =>to_date('20071031 12:00:00','yyyymmdd-hh24:mi:ss'));
6、查看日志分析的结果,通过查询v$logmnr_contents可以查询到
SELECT USERNAME,SQL_REDO,SQL_UNDO FROM
V$LOGMNR_CONTENTS WHERE USERNAME='TEST'
AND PERATION='DELETE';
输出结果同上一个实验.在这里就不在贴出结果。
7、结束LogMiner的分析。
execute dbms_logmnr.end_logmnr;
PL/SQL 过程已成功完成。
8、可以把这个文件从日志分析表中移除,从而不进行分析。
SQL> execute dbms_logmnr.add_logfile(options =>dbms_logmnr.removefile,logfilename =>'d:oracleora92rdbmsARC00038.001');
PL/SQL 过程已成功完成。
