Shoba,
I’m not too sure which database connection properties you are taking about – could you elaborate?
If you are looking at deploying assembly resources to BizTalk, you should take a look at the ‘BTSTask AddResource’ command (see http://msdn.microsoft.com/en-us/library/aa578463.aspx for more information), which allows you to specifiy the server name and database that the assembly should be deployed to.
Rgds, Nick.
