查到的session_info为空处理：
1.select supplemental_log_data_min,supplemental_log_data_pk,supplemental_log_data_ui from vdatabase; alter database drop supplemental log data (primary key, unique index) columns; alter database add supplemental log data; ....过30分钟 2、将redo日志文件添加到logmnr分析日志列表 exec sys.dbms_logmnr.add_logfile(logfilename=\>'redo日志1', options=\>sys.dbms_logmnr.new); exec sys.dbms_logmnr.add_logfile(logfilename=\>'redo日志2', options=\>sys.dbms_logmnr.addfile); exec sys.dbms_logmnr.add_logfile(logfilename=\>'redo日志n', options=\>sys.dbms_logmnr.addfile); 3、启动并分析redo日志 exec sys.dbms_logmnr.start_logmnr(options =\> sys.dbms_logmnr.dict_from_online_catalog); 4、查看分析结果 spool c:\\log.txt select \* from vlogmnr_contents ;
spool off
5、停止logmnr
exec sys.dbms_logmnr.end_logmnr
6、取消补充日志
alter database drop supplemental log data (primary key) columns;
alter database drop supplemental log data (unique) columns;
alter database drop supplemental log data;
