Greetings, I am trying to tune my application and the first step is to test certain long-running queries to see if certain variations in the MDX will allow them to run faster. The problem is that I keep getting timeouts on my test server after ~1000 seconds or so. I have altered the timeout properties in the following locations: On the XMLA server: Analysis Server timeout property = 24000 seconds IIS timeout property for the website = 24000 seconds httpExecution timeout in machine.config = 24000 seconds datasources.xmla timeouts (both named and unnamed) = 24000 seconds On the Web Server (at this time it is my desktop -- I am running the code in the debugger): httpExecution timeout in machine.config = 24000 seconds IIS timeout property for the website = 24000 seconds I am missing something. Can someone help me? Thanks, Chris Magoun
