"Heterogeneous queries and use of OLEDB providers are not supported in fiber mode."

This is a classic.


I've seen this in environments where someone is trying desperately to resolve SQL Server performance issues.  Out of the blue, linked server/DTC queries will begin to fail with the following error message:


Heterogeneous queries and use of OLEDB providers are not supported in fiber mode.

Using a DDL trigger push changes over a linked server

Here's a script I put together to automatically propagate schema changes to keep two SQL Server databases in sync using a DDL trigger.  This could just as easily be applied to two databases connected by linked server connections.

This isn't the only solution for schema-only change propagation, I'll have a blog post on that later and update this one when I do.
