ORA-01591: lock held by in-doubt distributed transaction

ORA-01591: lock held by in-doubt distributed transaction

引文档如下:


错误代码:ORA-01591


错误原因:使用了分布式事务，造成这个问题的原因很多时候都是由于网络问题造成的


解决办法:


1.找到TRAN_ID
Select 'Rollback force '''||LOCAL_TRAN_ID||'''' from sys.pending_trans$;




2.將其COMMIT或ROLLBACK:  
rollback force LOCAL_TRAN_ID;  
commit force LOCAL_TRAN_ID;  


3.如果执行失败,则强行从资料字典中删除该交易记录:
set transaction use rollback segment system;   
delete from dba_2pc_pending where local_tran_id = LOCAL_TRAN_ID;   
delete from pending_sessions$ where local_tran_id = LOCAL_TRAN_ID;   
delete from pending_sub_sessions$ where local_tran_id = LOCAL_TRAN_ID;   
commit;


4.执行失败,还一种情况可以尝试下重起一下Oracle服务,这种情况我遇到过一次，重新启动后该锁自动解除（因为对删除数据字典比较担心,所以胡乱试了一次重启数据库,前提是执行了commit force LOCAL_TRAN_ID;失败之后重新启动）


5.生成语句操作语句的程序


begin 
  for r in (select local_tran_id  
              from dba_2pc_pending t  
             where t.state = 'collecting') loop  
    --dbms_output.put_line('commit force '''||r.local_tran_id||''';');  
    dbms_output.put_line('delete from dba_2pc_pending where local_tran_id = '''||r.local_tran_id||''';');  
    dbms_output.put_line('delete from pending_sessions$ where local_tran_id = '''||r.local_tran_id||''';');  
    dbms_output.put_line('delete from pending_sub_sessions$ where local_tran_id = '''||r.local_tran_id||''';');  
  end loop;  
  dbms_output.put_line('commit;');  
end;
