ORA-02051: another session or branch in same transaction failed or finalized ORACLE 报错 故障修复 远程处理
文档解释
ORA-02051: another session or branch in same transaction failed or finalized
Cause: A session at the same site with the same global transaction ID failed. The failure could also be caused by an application error if an attempt was made to update the database while another tightly coupled transaction branch with the same global transaction ID was finalized or aborted.
Action: No action necessary as the transaction will be automatically recovered. In the case of an application error, make sure there are no more updates to the database once the transaction manager has started two-phase commit for tightly coupled distributed transaction.
Oracle ORA-02051 错误消息指示另一个会话或分支参与相同的事务,但未能成功完成或已结束。
官方解释
ORA-02051:另一个会话或分支参与相同事务,但已失败或终止。
这是一个严重级别的错误,即代码20,非死不可。
此错误出现的一般原因是一些事务操作发生在一个活动的数据库会话或分支中,但它也由于某些原因未能提交或正常完成,如连接中断,网络中断或程序代码不正确。
常见案例
在运行查询时发生ORA-02051错误,如:
SELECT * FROM table_name;
ERROR at line 1:
ORA-02051: another session or branch in same transaction failed or finalized
正常处理方法及步骤
1、使用活动会话识别哪个会话(如果可用)在运行相同的事务,并调查它的活动状况。如果有必要,可以尝试终止该会话,以确定是否解决了问题。
2、尝试使用原子释放来完成当前的事务:
COMMIT FORCE ‘transxn’;
3、如果当前事务是实际发生错误的会话的一部分,则可以使用以下语句来强制提交:
ALTER SYSTEM COMMIT FORCE ‘transxn’;
4、如果错误仍在发生,则可能需要重置数据库(关闭,然后重新打开)。
