23 November 2009 18:13

Ok, so your reaction to the title is probably the same as mine when i found out about SSAS server level locks!

To date i had always used the profiler gui to do the SSAS tracing but today i found myself needing to initiate and manage a trace with scripts. The good news is that it can be done!
