常见案例

一般情况下，当开发人员尝试初始化LogMiner时，就会发生这种情况。

正常处理方法及步骤

1. 首先，查找所有活动的LogMiner会话：

select sid, serial# from v$session

where program like ‘%LogMiner%’;

2. 关闭此会话：

alter system kill session ‘SID,Serial#’;

3. 再次初始化LogMiner：

begin

dbms_logmnr.add_logfile();

dbms_logmnr.start_logmnr(

options=>dbms_logmnr.dict_from_online_catalog);

end;
