Has anyone come across any good tools (preferably but not necessarily FOSS) that can read a SQL Server (2005/2008) trace file and execute the commands against another database. We are attempting to perform some performance testing on our SQL servers and would like to replicate an actual load.
I have come across but not yet used:
You can replay a SQL Server Profiler trace against another server using the SQL Server Profiler itself.
See the following Microsoft Reference as a starting point.
Quest Software also have a tool called Benchmark Factory that can be used to perform SQL Server load testing.
