Sql 无法安装程序集“amqmdnet”，因为现有策略将阻止它被使用

嗨， 我尝试在SQL server中注册amqmdnet.dll作为IBM WebSphere MQ for Windows的一部分，以便部署SQL CLR存储过程将其用于MQ mesaging

create assembly amqmdnet                                                
from 'c:\mssql\assembly\amqmdnet.dll'                                   
with permission_set = unsafe   

Msg 6586, Level 16, State 1, Line 1                                     
Assembly 'amqmdnet' could not be installed because existing policy      
would keep it from being used.  

代码是：

create assembly amqmdnet                                                
from 'c:\mssql\assembly\amqmdnet.dll'                                   
with permission_set = unsafe   

Msg 6586, Level 16, State 1, Line 1                                     
Assembly 'amqmdnet' could not be installed because existing policy      
would keep it from being used.  

服务器的响应是：

create assembly amqmdnet                                                
from 'c:\mssql\assembly\amqmdnet.dll'                                   
with permission_set = unsafe   

Msg 6586, Level 16, State 1, Line 1                                     
Assembly 'amqmdnet' could not be installed because existing policy      
would keep it from being used.  

-版本：

create assembly amqmdnet                                                
from 'c:\mssql\assembly\amqmdnet.dll'                                   
with permission_set = unsafe   

Msg 6586, Level 16, State 1, Line 1                                     
Assembly 'amqmdnet' could not be installed because existing policy      
would keep it from being used.

CLR已启用，Trustly已启用，其他CLR过程工作正常

create assembly amqmdnet                                                
from 'c:\mssql\assembly\amqmdnet.dll'                                   
with permission_set = unsafe   

Msg 6586, Level 16, State 1, Line 1

如何解决这个问题

您使用的是什么版本的MQ？我能够在SQL Server 2008 R2上成功注册WMQ 7.5.0.0版本amqmdnet.dll。MQ和SQL Server均未应用任何service Pack。@Shashi amqmdnet.dll版本为7.5.0.2您是否取得了任何进展？MQ程序集是否在GAC中？如果是这样，您是否可以从GAC取消注册MQ程序集，然后在SQL Server中运行创建程序集？要取消注册MQ程序集，可以从/bin目录运行amqiregisterdotnet.cmd/u bat文件。@Shashi谢谢！从GAC注销ASM后，dll已在SQL中成功注册。不幸的是，这部电影的作者盖伊现在正在度假。几周后他将继续工作：太好了！如果策略文件位于GAC中，SQL Server似乎存在一些问题。
