＆＃34;新事务无法在指定的事务协调器中登记＆＃34;在链接服务器到Oracle

Question

当我尝试使用＆＃34; BEGIN DISTRIBUTED TRANSACTION＆＃34;从链接服务器调用storedprocedure时命令，我收到以下错误。

OLE DB provider "OraOLEDB.Oracle" for linked server "LINKSERVER2" returned message "New transaction cannot enlist in the specified transaction coordinator. ".
Msg 7391, Level 16, State 2, Line 4
The operation could not be performed because OLE DB provider "OraOLEDB.Oracle" for linked server "LINKSERVER2" was unable to begin a distributed transaction.

当我这样跑时，程序通过。

set @sql=  'begin INSERT INTO FEED.K_PACKING_CHARGE(org_code , sale_packing_size , amount)
VALUES (''2'' , ''100'' ,  ''3''); end;'

exec (@sql)  AT LINKSERVER_1 ;

但是当我尝试添加＆＃34;开始分发交易＆＃34;命令，我收到错误

BEGIN DISTRIBUTED TRAN
set @sql=  'begin INSERT INTO FEED.K_PACKING_CHARGE(org_code , sale_packing_size , amount)
VALUES (''2'' , ''100'' ,  ''3''); end;'

exec (@sql)  AT LINKSERVER_1 ;
 COMMIT

如果我在某台计算机上运行创建链接服务器，则没有问题。但是我使用两台计算机（一台是MSSQL服务器，另一台是Oracle数据库），我收到错误。
