二.分析

此类问题通常是由于网络问题或远程数据库异常导致的分布式事务失败。

执行下面SQL语句

select LOCAL_TRAN_ID,GLOBAL_TRAN_ID,STATE,MIXED,HOST,COMMIT# from dba_2pc_pending;#dba_2pc_pending视图记录等待恢复的分布式事务的信息select * from DBA_2PC_NEIGHBORS;#视图记录未决的分布式事务的输入输出连接信息

三.处理

1.如果在上述视图中查询到记录，则尝试force commit/rollback

commit force '644.3.881743';

2.如果不成功则进行如下操作

(1).Disable分布式恢复SQL> ALTER SYSTEM DISABLE DISTRIBUTED RECOVERY;System altered. (2).Puege(清空)in-doubt transaction entry：SQL> exec DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('644.3.881743');PL/SQL procedure successfully completed. (3).然后enable 分布式恢复：SQL> ALTER SYSTEM ENABLE DISTRIBUTED RECOVERY;
