ORA-16123 错误表示有一个显式的事务需要提交前的确认。这在执行跨多个表的复杂操作时可能会发生,例如从一个数据库表移动大量数据到另一个数据库表中。

官方解释

ORA-16123 表示发出方正请求提交一个显式事务,但该事务太复杂,超出系统能处理的范围,需要 DBA 预先确认,即该事务安全可以提交。

常见案例

常见的发生案例是在执行更新数据的操作时,事务太复杂,涉及多张表,超出系统能处理的范围,这时需要 DBA 预先确认,才能够将其提交。

一般处理方法及步骤

1.确认是哪个用户提交了此事务,使用下面的语句:

select session_id, serial#, distinct client_process, username from v$session;

2.将查询结果里username 为此用户,会话 ID (session_id) 及序列 (serial#) 锁住:

alter system kill session ‘session_id, serial#’;

3.将此用户的锁解开:

alter system unlock session ‘session_id, serial#’

4.使用授权的启用和禁用功能,让用户可以提交事务:

alter user user_name identified by 设置密码; grant select, update, delete, insert on table_name to user_name; grant commit to user_name;

5.用户提交事务后,再禁用该用户的权限:

revoke select, update, delete, insert on table_name from user_name; revoke commit from user_name; alter user user_name identified by 空;
