服务器“服务器不可用"上的MSDTC [英] MSDTC on server 'server is unavailable'

问题描述

我在SQL Server上收到此奇怪的错误.而且我在较旧的帖子中找不到解决方案.

I get this weird error on SQL Server. And I cannot find solution in older posts.

我有此过程:

create proc _upJM_SyncAll_test
as
begin
    DECLARE @SQLString nvarchar(max)

set @SQLString = N'
DELETE FROM OPENQUERY([LOCAL_MYSQL],''SELECT acSubject FROM _utjm_setitemprices'') where acSubject not in (select acSubject from _uvJM_SetSubj)
DELETE FROM OPENQUERY([LOCAL_MYSQL],''SELECT acSubject FROM _utjm_setsubj'') where acSubject not in (select acSubject from _uvJM_SetSubj)

update a
set acName2 = b.acName2,
    acName3 = b.acName3,
    acAddress = b.acAddress,
    acPost = b.acPost,
    acPostName = b.acPostName, 
    acCountry = b.acCountry, 
    acVATCodePrefix = b.acVATCodePrefix,
    acCode = b.acCode, 
    anDaysForPayment = b.anDaysForPayment
from OPENQUERY([LOCAL_MYSQL],''SELECT * FROM _utjm_setsubj'') a join _uvJM_SetSubj b on (a.acSubject = b.acSubject)
where 1=1
and (   isnull(a.acName2,'''') <> isnull(b.acName2,'''') OR 
        isnull(a.acName3,'''') <> isnull(b.acName3,'''') OR 
        isnull(a.acAddress,'''') <> isnull(b.acAddress,'''') OR 
        isnull(a.acPost,'''') <> isnull(b.acPost,'''') OR 
        isnull(a.acPostName,'''') <> isnull(b.acPostName,'''') OR 
        isnull(a.acCountry,'''') <> isnull(b.acCountry,'''') OR 
        isnull(a.acVATCodePrefix,'''') <> isnull(b.acVATCodePrefix,'''') OR 
        isnull(a.acCode,'''') <> isnull(b.acCode,'''') OR 
        isnull(a.anDaysForPayment,'''') <> isnull(b.anDaysForPayment,'''')
)

insert into OPENQUERY([LOCAL_MYSQL],''SELECT * FROM _utjm_setsubj'') (acSubject, acName2, acName3, acAddress, acPost, acPostName, acCountry, acVATCodePrefix, acCode, anDaysForPayment)
select b.acSubject, b.acName2, b.acName3, b.acAddress, b.acPost, b.acPostName, b.acCountry, b.acVATCodePrefix, b.acCode, b.anDaysForPayment
from OPENQUERY([LOCAL_MYSQL],''SELECT * FROM _utjm_setsubj'') a right join _uvJM_SetSubj b on (a.acSubject = b.acSubject)
where a.acSubject is null '

EXECUTE sp_executesql @SQLString;
end

当我在Management Studio中运行程序时，如下所示:

When I run procedure in management studio like this:

  exec dbo._upJM_SyncAll_test

一切正常.我没有错误，同步工作正常.

everything is OK. I get no error, sync is working just fine.

但是当我在触发器中执行以下代码时:

But when I put execute in trigger like this:

create trigger _utrJM_SetSubj on tHE_SetSubj after insert, update, delete
as
begin
    exec dbo._upJM_SyncAll_test
end

我收到此错误:

消息8501，级别16，状态3，过程_upJM_SyncAll_test，第54行
服务器服务器"上的MSDTC不可用.

Msg 8501, Level 16, State 3, Procedure _upJM_SyncAll_test, Line 54
MSDTC on server 'server' is unavailable.

过程_upJM_SyncAll_test只有39行...

Procedure _upJM_SyncAll_test has only 39 lines...

推荐答案

对于我来说，该服务已已停止.解决方案:需要打开MSDTC服务

In my case, the service was stopped. solution: need to turn the MSDTC service on

1. 转到服务. (开始>设置>控制面板>管理工具>服务)
2. 找到名为"分布式事务处理协调器"的服务，然后 右键单击(在其上并选择)> 开始.
3. 使此服务自动运行 ，以永久解决此问题

1. go to Services. (START > SETTINGS > CONTROL PANEL > ADMINISTRATIVE TOOLS > SERVICES)
2. Find the service called 'Distributed Transaction Coordinator' and RIGHT CLICK (on it and select) > Start.
3. make this service to run Automatically for solving this issue permanently
